How to install fishing line on a champion petrol trimmer

The type of lawn mower, such as a trimmer, is divided into several main categories: petrol, battery, mechanical and electric. Each has a unique structure.

In a gasoline engine, fuel is mixed with air until it enters the cylinder and is then ignited by a spark plug. Power is regulated by the amount of mixture supplied using the handle or gas pedal. The gasoline engine has high speed and power density with relatively low noise levels. It has a simple design. The main disadvantage. fuel consumption.

Electric motor It produces not only environmentally friendly operation, but also much lower noise levels. For an electric motor to work, it must be connected to a power source, such as 220-380 volts.

The advantage of a battery type motor is that you do not need a constant connection to the mains. The tool allows you to work intensively until the battery runs out.

Engine power (displacement) trimmers. This is one of the most important characteristics of an internal combustion engine (ICE). The internal combustion engine converts the energy obtained from fuel combustion into mechanical energy. This process occurs in the combustion chamber (cylinder) of the engine. Next, mechanical energy is transmitted through various components and assemblies to the wheels of the lawn mower (lawn mowers, aerators, verticals, etc.). The cylinder volume, or the sum of the cylinder volumes, determines the size of the engine. Its power largely depends on the power of the engine, since much more fuel is burned with more fuel. With higher engine power, engine life is longer because it does not have to work to its limit.

Fuel tank trim volume. An important characteristic of the engine, which is responsible for the duration of operation. Fuel tank. This is a tank for storing and returning fuel (gasoline, diesel) to the internal combustion engine. Fuel tanks are mainly made from steel, plastic or aluminum.

If the tank capacity is too small, frequent refueling stops are required. The more powerful the engine, the greater the consumption of the combustible mixture; accordingly, the larger the tank must be in order to continuously process the required area. Tank capacity is measured in liters.

Trimmers are gas, electric or even rechargeable. They are equipped with engines that are different. Most models of gasoline trimmers have a top engine. Top motor trimmers are more practical, properly balanced and have high power, which is great for intensive lawn processing. Such engines have good cooling and are maximally protected from mechanical damage and moisture.

From the bottom of the engine, Generally, electric trimmer models are available. They are characterized by low power and small overall dimensions. They also do not cool well and have some length limitations. They are not protected from moisture and mechanical damage.

For ease of understanding, the power of internal combustion engines is usually measured in Horsepower (H.P.). The more powerful a lawn engine, the more work it can do in less time. But for heavy duty work, you need to consider the torque achieved at a certain engine speed as it depends on the traction force and the higher the torque (measured in Newton meters), the easier it will be for your machine to cope with heavy work.

When choosing lawn equipment (lawn mowers, lawn mowers, aerators) with a certain power, it is necessary to take into account: the type and volume of work performed, the size of the area, and soil properties.

Motor trimmer power, adjustable by pressing the pedal or gas. The more you press, the more fuel is delivered. the air mixture in the combustion chamber increases power accordingly. The efficiency of an internal combustion engine trimmer is measured by fuel consumption in grams to obtain a kilowatt-hour.

Modern trimmers are designed for lawn care; depending on the model, they can be equipped with different cutting elements; this can be used to mow a variety of vegetation.

The most common attachment is considered to be a hair growth line or, as it is called, a cord. Main purpose: mowing grass in not very neglected places (it’s convenient to get around fences, trees, buildings). It is wound on a special head with the release of a pair of ends that serve as a cutting tool. They can be from 0.8 to 5 mm thick. The dense hairs are used on high-power gas trimmers and can trim large weeds, thick stems of dry grass and the soft new growth of small shrubs. Chisels up to 2 millimeters are used mainly on electric trimmers because they have a less powerful motor and design.

According to the method of releasing the fishing line, it is divided into: manual, semi-automatic (the cord is pulled out from the head when the operator presses it to the ground) and automatic (the fishing line is extended to the required length when speed is gained). In the latter case, there is a high consumption of the cutting element, so semi-automatic models are the most popular.

When trimming thicker grass or shrubs, use a knife or disc. A knife can be made of plastic or metal and have a different number of blades. For the most difficult work (shrubs, small young trees), metal discs with a large number of teeth are used. Some trimmer models may be equipped with a saw blade (height cutter) designed for trimming tree branches.

The ability to use knives and blades depends on the power of the engine and the design of the trimmer, you must carefully follow the instructions. For curved rod models, you can use fishing rods and small plastic knives.

Metal blades and discs are used on straight trimmers. Because this design is safer for the operator (the greater the distance from the cutting head, the special handle, the stop). When a knife or disc touches a hard surface, it is often thrown back. Additionally, a heavier tool places more stress on the trimmer's components.

Choosing a line for a trimmer head

There are many types of heads that are designed for different types of fishing line. The latter is also available in several diameters: from 1.0 mm to 3.2 mm. Moreover, its cross-section can be round (including with a special groove to reduce noise), square, twisted and star-shaped.

There are no clear preferences, which explains the wide variety of shapes and diameters on the market. The round shape is usually stronger, but has poorer cutting ability, and also produces a characteristic sound when rotated. Therefore, sometimes an acoustic groove is made on it, however, the use of this fishing line makes sense only on battery-powered trimmers; in machines with a gasoline engine and mains drive, the sound level of the drive itself practically drowns out the sound from the fishing line. A square has good cutting ability, and despite the fact that such a fishing line is less durable than a round one, on average it is consumed less. A square fishing line quite easily cuts off shoots of the same willow up to 1 cm in diameter. The star has the maximum number of cutting edges, cuts the best and is consumed the fastest.

The next nuance when choosing is rigidity. The fact is that when producing nylon, a modifier (often maleic anhydride) is added to it, which improves its strength and prevents tearing. However, modifiers are not the cheapest component; they are trying to save money on them. Therefore, a seemingly good fishing line that was left over for the winter suddenly behaves completely differently in the spring - it breaks and stops coming out of the reel normally. There is a recommendation to soak the fishing line in water before work, but I don’t see much point in this; maleic anhydride interacts with water, but if there is not enough of it in the nylon, then there will be nothing to interact with. Therefore, there is no point in stocking up on fishing line for a long period of time; breaking or constantly tearing fishing line, which also does not want to come out of the reel itself, can significantly complicate the work.

The trimmer is the most common unit used for cutting grass and cutting small bushes. This device is distinguished by its ease of maintenance, easy operation during operation, and thanks to its low weight, even ladies can handle a child. Everyone understands that for high-quality work on mowing grass, the correct selection of cutting tools is required. As a last resort, trimmers use special cutting attachments (discs, knives), or trimmer heads with fishing line inside. Nozzles and fishing line are consumable tools; if the knives have the option of sharpening, then when the fishing line is used up, it needs to be changed. Here we will tell you very carefully how to change fishing line correctly.

The mowing head for grass is a cylindrical body where a reel (spool) with a fishing line (cord) tucked in is inserted. This design can be installed on both gasoline and electronic trimmers. The heads differ in the method of threading and feeding the cord and come in 3 types.

Automatic. The cord is fed if the user reduces the engine speed. Although automatic line feeding is convenient if huge amounts of work are being done, such bobbins have one drawback - high thread consumption.
Automatic. The implementation of this type of heads does not require the user to perform complex manipulations. The principle of their operation is designed in such a way that the cord is automatically extended, like an office cord, when the machine is running at full speed. Simply hit the trimmer head slightly on the ground (this releases the blockage of the cord), and the line, thanks to centrifugal force, moves out of the spool, after which it is cut to the appropriate length with a knife placed on the protective casing.
Manual. To lengthen the cord, the machine must be stopped, after which the line is stretched manually.

For the above reasons, automatic bobbins are the best option. It should also be noted that trimmer reels come in single-string types (used only for trimming grass) and double-string ones, which are used for mowing tall grass and small, thin-trunked shrubs.

Before starting the process of changing the cord, trimmer users need to remove and disassemble the reel. Let's look at how to do this.

The trimmer's mowing head consists of several parts: a casing, a spring (not on all models), a bobbin with cord and a cover.

Attention! Before proceeding with any maintenance activities on the electronic unit, it must be disconnected from the network.

In most cases, trimmers use 3.5 mounting options for the mowing head.

To remove the trimmer head, you will need to completely disassemble it.

To remove the cover covering the inside of the head, you need to press the latches (latches) located on both sides of it.

In this embodiment, the head is screwed onto the gearbox shaft. To remove it, you will need to fix this popular rumor. For this purpose, similar trimmers, for example, Huter and Champion devices, have a hole through which you can insert either a narrow screwdriver or an iron rod.

What is needed to remove the bobbin, do 3.5 regular steps.

Insert a screwdriver into the hole and lock the shaft.
Grasp the head housing and begin to twist it clockwise. It should be twisted in this direction due to the fact that the thread cut on the shaft is left-handed.

What is the duration of the project, what model of trimmer is used, the type, thickness and length of fishing line is selected. The diameter of the cord is possibly from 1.2.7 to 4 mm. It’s easy to think that the thicker you thread the cord, the more tough and thick grass it can cut.

Almost always use a universal fishing line with a diameter of 4.5 mm.

There are 3 methods to find out what size line your mower is using.

What is needed to replace the cord

With regular use of the trimmer to cut grass, the discs become dull, but they can be sharpened and continue to be used. The line in the reel tends to run out, so it becomes necessary to refill a new one, for which you need to determine the type of head and prepare a cord of the required thickness and length.

So, the mowing head is a cylindrical body in which a spool with fishing line is located. This detail is present on both electric trimmers and gasoline scythes of any brand, be it Bosch, Makita, STIHL or another brand. There are three types of heads depending on the method of threading and feeding the line.

The operating principle of the automatic group heads is that they independently feed the line when the mower reduces the engine speed. Such designs are convenient when working on large areas, but have the disadvantage of high cord consumption.
The heads of the semi-automatic group are easy to operate - automatic line feeding is performed at maximum engine speed. To unblock the cord, you need to gently tap the tool on the ground, after which the unlocked thread moves out of the spool. Trimming to the required length is done with a knife mounted on a protective casing.
Trimmers with manual line feed must first be turned off, and then pull out the line yourself.

On a note! The most convenient and best priced are semi-automatic cord reels.

Reels for electric and gasoline streamers can be with one or two tendrils of fishing line. The former are used for trimming low grass growth, the latter - for mowing tall grass and small shrubs.

On a trimmer head with automatic refilling

For heads with automatic threading, you just need to wind and clamp the edges of the fishing line, and the tool will perform further winding on its own when turned on. It is impossible to make a mistake here, because the coil itself recognizes how the antennae should be positioned.

On a note! The advantages of trimmers with such a head include the convenience of laying the cord, but the disadvantages are high cost and difficult repairs.

Line selection

In order for threading the fishing line into the trimmer head to be successful, it is important not to make a mistake with the choice of consumables. The thicker the cord you set, the thicker and tougher the grass it will be able to cut. Universal fishing line , the diameter of which is 2 mm. You can select the diameter suitable for the mower in the following ways:

Check the instructions that came with your trimmer for line thickness information.
Pay attention to the bobbin itself. Sometimes it contains information about possible fishing line diameters.
Another option is to try inserting the cord into the outlet hole. If it fits through it without difficulty, then the selected fishing line diameter is suitable for use.

You can select the cord thread according to the type of engine. If the line is too thick, the resistance to rotation will increase - in this case the engine will overheat greatly and will soon fail. Useful tips:

For an electrical device with a motor less than 500 V, a thread with a thickness of 1.3 mm is suitable. If you can’t find one, then you can use a 1.6 mm fishing line. If the power is more than 1 kW, then choose a cord with a diameter of 2 mm.
With a gasoline trimmer, the shaft mower matters. For the bent version, a 2 mm cord is often used. If the shaft is straight, then install a thread of 2.4–2.5 or 3 mm. The thickest fishing line is installed on powerful devices - from 1.3 kW.

Pay attention to the type of cross-section of the cord thread. Some popular options:

The most common fishing lines are with a round cross-section. They mow down fresh grass well, but cope less well with shrubs and dead wood.
Twisted (spiral) cord is not very strong, but is well suited for thin young grass.
The jagged thread with sharp edges is ideal for large weeds in neglected areas.
You can mow your lawn more evenly with a rectangular, star or square trimmer line, but they are not very strong.
The strongest is a two-component cord with an internal core and a round cross-section.

Types of trimmer line

Please note that you cannot use wire, metal strings and cables, or regular fishing thread instead of fishing line. The device will be dangerous both for the user and for others. So the cable or similar products will gradually begin to work, as a result of which their ends will unravel and small pieces will fly apart at high speed.

Models of trimmers

The following models of Champion petrol trimmers are now available on the Russian market.

T252 is the simplest, cheapest and most compact model weighing less than 5 kg. Equipped with a two-stroke engine with a power of 0.75 kW and a volume of 25.4 cubic meters. cm, which provides an idle speed of up to 2800 rpm. Gas tank volume – 0.75 l. An ergonomic P-shaped handle and a curved detachable rod with a length of 1585 mm provide good maneuverability and ease of use of the product. A fishing line with a diameter of 2 mm is used as a cutting unit, which provides a cutting area width of 38 cm.

Such characteristics make it possible to use this option for caring for small home lawns with thin grass.

T256 is a modernization of the previous model, characterized by the use of a straight rod 1493 mm long and a U-shaped handle. As a cutting unit, either a spool of fishing line with a diameter of 2.4 mm is used, which provides a working area width of 40 cm, or a three-pronged knife, which provides mowing in an area 25.5 cm wide. The presence of a knife and a thicker fishing line allows this option to be used for home lawns with fairly thick grass and small bushes. The weight of the product is about 6 kg.
T333 - this brush cutter differs from the T256 model with a more powerful (0.9 kW, 32.6 cc) engine and a 0.95 liter gas tank, which allows it to be used for tidying up larger lawns. Weight – 6.7 kg.
T433 – differs from the T333 model by an even more powerful motor (1.25 kW, 42.7 cc), which allows it to be used for caring for lawns with thick grass and tall, strong shrubs. The increase in power led to an increase in the weight of the product to 8.2 kg.

T433-2 is an upgrade of the previous model, equipped with a spool of cutting line with a diameter of 3 mm, which allows you to cut even thicker grass.
T433S-2 - differs from the T433 model by the use of a reinforced one-piece rod and a carbide cutting blade with 40 teeth, which allows you to cut the thickest grass and shrubs.
T523 - differs from the T433 lawn mower by installing an even more powerful engine (1.4 kW, 51.7 cc), which increased the weight of the product to 8.3 kg. In addition, this option is equipped with a carbide knife with 40 teeth.
T374FS is an industrial lawn mower for the care of large lawns and gardens with a four-stroke engine with a power of 1 kW and a volume of 37 cubic meters. cm. Fuel tank volume – 0.75 l. A knife with 3 teeth is used as a cutting tool, providing a working area width of 25.5 cm. Weight - 7.5 kg.
T394FS-2 is another industrial version with a 4-stroke engine with a power of 1.2 kW and a volume of 38.9 cc. cm. Gas tank volume – 0.9 l. As a cutting unit, it is possible to install a spool of fishing line with a diameter of 2.4 mm, providing a mowing width of 44 cm, or an 80-edged knife with a working area width of 25.5 cm. The mower weighs 7.7 kg.

Previously, the company also produced a gasoline mower LMH5629, equipped with wheels, but this model is currently discontinued.

HOW TO CHANGE THE LINE TO AN Electronic TRIMMER

To correctly find how many meters of fishing line will be needed for a particular reel, you need to wind it onto the bobbin in such a way that the skein does not exceed the diameter of the sides. If the line sticks out over the edges of the spool, you cannot stick it into the housing. When you have decided on the length of the material, you need to thread it into the bobbin, so do the following.

You need to fold the fishing line in half so that one end is 10-15 cm longer than the other.
Be careful that the bobbin is divided into 5 parts by the central edge, from which charging begins. Find a groove in it and insert a cord, bent twice, into it, applying a little force.
It is of fundamental importance to find in which direction the line on the reel. If you look closely, you will of course find an arrow or an inscription with an arrow on the bobbin indicating which direction the winding should be carried out. There are times when there is no arrow on the reel. Under these circumstances, look for the arrow marked on the mowing head and wind the cord in the opposite direction.
Winding should be carried out carefully, turn to turn, with the highest thread tension.
When laying the cord is completed, you will need to first secure the small end of the fishing line by inserting it into a groove of suitable diameter on the side of the reel.
The second end, the longer one, is attached to the groove on the back of the bobbin.
After fixing the fishing line, trim its ends, leaving an allowance of about 10 cm.
Next you need to install the loaded reel into the mowing head. For this purpose, alternately inserting and pulling the thread along the output holes of the head, place the bobbin in the casing, then, applying the required force, pull the line out of the fixing grooves and tighten it.
Now there is an option to put on the cover and secure it with latches.

Some reels provide a second method of fastening the cord: you can load 4 pieces of thread, instead of 1, folded in half. The line is changed using the following method.

Before changing what is also called loading the new thread into the spool, determine how many meters of it will be needed using the method discussed above.
Bend one end of the cord to form a hook.

For Shtil brand brush cutters, there is a very simple and fast method of changing the fishing line without disassembling the mowing head, you can find out everything about it by watching this video.

The ends of the cord protruding from the holes in the casing must, of course, be cut to the required length when the part is installed in the trimmer. There are two ways to do this:

by turning on the trimmer (when rotating, the ends of the fishing line will be cut on a knife attached to the protective casing);
cutting off the excess ends with scissors in such a way that they do not touch the casing body.

The second method is used if there is a passage, if it was necessary to install a cord of huge diameter, and the trimming knife is not able to shorten it.

See information regarding cord thickness in the instructions for the device.
Look at the bobbin itself. On its surface there may be information about the probable diameters of the fishing line.

The line is wound onto a reel located in the mowing head. Therefore, first you need to open it (this was discussed above). There are 2.4 methods for winding cord.

Preparing for replacement

Disassembling the trimmer spool

For clarity, the mowing head (spool) was removed from the brush cutter. To change the fishing line, you don’t need to remove it; everything is done locally. It does NOT take a lot of time.

We disassemble the trimmer spool. it is held on by latches. Remove the cover by pressing the latches. If you do this with your hands, there is not enough effort, then use a screwdriver.

The spool consists of the following:

Housing with spring
Cover with locking latches
Reel with button

The principle of action is the following. By pressing the button, the reel presses on the spring and comes out of the fixing grooves in the spool cover. By holding the reel in this state, you can rotate it and adjust the length of the fishing line. When the button is released, the housing spring returns the coil to its initial fixed state.

Disassembled trimmer spool

There are several holes on the bottom of the reel for different diameters of lines. These may vary among different trimmer manufacturers. In some cases (like here) they are signed, in others they are.

These holes are necessary to fix the fishing line when replacing it. After winding the grandmother's fishing line, the ends of the latter are inserted into them. This is necessary so that the line does NOT unwind when the reel is installed in the trimmer body. In other words, it makes line changes easier.

Holes for fixing fishing line

There are models without indicating the diameter of the consumables. Then, in order to find out what is the largest diameter of line that can be used, it is tried on using the holes for the line exit from the trimmer spool body (see Sketch below).

Trying on the fishing line exit holes

The reel has two sections for fishing line, separated by a partition. They may not exist. They are only needed to differentiate and facilitate winding of consumables.

Two sections for fishing line

First, the required length of the loess is determined. The latter is wound into one of the sections of the coil so that it does not go beyond its limits. In this case, 3 mm was wound, the length was about 2 meters. THOSE. For 2 sections, a 4-meter length will be useful. This is for the 1st method. For the second method, two sections of 2 meters are required.

Determining the required line length

Now you need to figure out which way you need to wind it. To do this, many manufacturers of trimmers put special markings on the reels, such as in the figure below.

Special designation on the reel

If no such markings were found, then you must direct your attention to the spool body. There, in an inescapable order, there is an arrow that shows the movement of the mowing head. The line is wound in the opposite direction.

Designation on the spool body

Step three: assembly of the head assembly

Pull the ends of the line through a pair of rounded slots on the reel. Replace both washers and the spring (if any in the design) included in the package with new elements. Bend both ends of the fishing line at right angles.

The last technical touch of the process of replacing the fishing line with the trimmer. placing the cover on the head with the following fixation by pressing force and turning slightly.

Pass each end through the hole in the base of the winding drum. Place the coil in the inner area of the head with emphasis on the spring. Place the lid, align it with the base and lightly press down with a slight counterclockwise rotation to place the lid on the tabs. This completes the replacement procedure.

If the thread has been loaded into the mowing head, but the protruding ends of the cord are not long enough, then before starting the machine they need to be lengthened - this applies to the head with manual adjustment. But there are cases when using an automatic mowing head when, due to the insufficient length of the protruding ends of the cord, they are not extended automatically. Here you need to turn off the unit (on an electronic device, you definitely need to unplug the plug from the socket), manually press the button located at the bottom of the part, and pull out a little fishing line. After this procedure, the cord will again be able to extend due to centrifugal force, if the spindle speed is set to the highest possible speed.

Whatever thickness of fishing line you use, you should keep in mind: in order not to constantly interrupt work and even change the cord, you should avoid areas where the working tool touches hard surfaces (pebbles, curbs, thick dry branches, etc.).

Some trimmer users are wondering: how to replace the cord that is used by default in this type of device? They begin to carry out dangerous experiments by installing iron or copper wire, iron cables, or even ordinary fishing line, into the mowing head.

If you install a metal cable instead of a fishing line, the trimmer turns into a dangerous device not only for the user, but for others. This fact is explained by the fact that during the operation of the unit, the metal cable will be evenly worked, its ends will unravel, and small pieces of wire will fly in different directions at high speed.

A similar thing happens with the use of metal or copper wire, only with the difference that the torn pieces will be larger and can cause significant injury.

If you happen to hook yours, or someone else’s leg, while working with an iron cable (wire), then a strong and deep tissue incision, and sometimes even amputation of your toes, is guaranteed for you. It is not in vain that the manufacturer uses nylon for such purposes, since it is quite light and strong, and when it comes off, it does not fly far and cannot cause injury.

Using fishing line in the trimmer instead of the standard one, of course, of course, but this will add unnecessary hassle for you, since it quickly wears out, breaks, mows slowly and is also not suitable for cutting tough grass. And in addition, when carrying out work, a long period of time is wasted in order to never replace a broken tool.

READ Trimmer works but does not turn

Automatic spools for trimmers, how often do they break?

These are modern coils that have high reliability and efficiency. The principle of their operation is such that the cord is lengthened when the engine speed is reduced in automatic mode. The mower does not need to control the process of feeding the line, as this happens automatically.

Automatic heads are 2-3 times more expensive than semi-automatic ones, so not every trimmer owner can afford such devices. However, experience confirms that a good and high-quality automatic reel for a trimmer or lawn mower lasts quite a long time and does not break. The advantages of automatic heads also include the high speed of line threading. To do this, the fishing line is threaded through the holes in the head, and it is wound manually onto the reel.

The test shown in the video below will help you verify the effectiveness of automatic trimmer reels. Heads of different types are used as experimental “rabbits”.

Types of trimmer heads for reels

The main element of the trigger is the mowing head, which is a cylindrical body with a reel (spool) inserted inside. The fishing line (cord) is tucked into it. The heads differ from each other in the method of feeding and threading the cord. There are three types of heads in total:

Automatic. The line is fed after this as the user reduces the engine speed. Automatic cord feeding is very convenient when you need to do a large amount of work. The disadvantage of such a head is the high thread consumption.
Semi-automatic. The use of such a head does not require the user to perform any complex manipulations. The principle of its operation is designed in such a way that the fishing line begins to automatically lengthen while the trimmer is operating at full speed. You just need to lightly hit the head of the device on the ground (this will remove the blockage of the fishing line), and the cord will move out of the bobbin due to centrifugal force. Then the fishing line is cut to the required length with a knife, which is located on the protective casing.
Manual. To lengthen the cord, you need to stop the machine. After this, the line will need to be pulled out manually.

Types of trimmer reels

How to wind fishing line onto the mowing head of a trimmer or brush cutter

For the second and third options, the coils, depending on the design, are disassembled using different methods. In reels with a lamb, the lamb is turned out, in reels with latches, the latches are pressed and one part of the reel is released from the other. If the halves of the spool are connected by thread, then it is enough to turn them by hand in the opposite direction until they are completely unscrewed.

Slowly completed disassembly of the spool reel without losing its spare parts allows you to move on to the main task - winding fishing line into the reel. The technological features of the spool design and the number of working antennae determine the sequence of actions.

The simplest option and easy sequence of actions:

The dimensions of the reel and the length of the unique factory winding determine the recommended length of fishing line for winding - 2...5 m.
One end of the fishing line is inserted into the fixing technological hole located inside the spool.
The fishing line is wound onto the drum in the reverse rotation of the spool in the direction of the trimmer - you, on the inside of the reel there is an arrow indicating which direction the winding is being carried out.
A small section of the fishing line is left free to be taken out - it is fixed in a special groove on the inside of the reel, created to hold the winding when assembling the spool into working condition.
The remaining end of the fishing line is passed through the hole in the outer part of the reel.
The reel halves are assembled and put on the trimmer rod.

In this type of spool, you should find the number of grooves for winding line lying on the inside of the reel:

one groove - both tendrils are wound together along one groove;
two grooves - who winds the tendril along a personal groove.

Remove the coil from the trimmer

On small electric trimmers with a bottom-mounted motor (where the motor is located near the ground when operating), the coil usually has two buttons on the sides. We press on them and disconnect one half of the coil body from the second, which remains on the trimmer . Along with the first half, the inner part is also removed, onto which the fishing line is directly wound. When disassembling, be careful: there is a spring inside that can fly out and get lost.

On electric and gasoline trimmers with a curved rod (such trimmers do not yet have the ability to install a knife), you need to grab the coil body itself with one hand, and with the other hand you need to start rotating the thumb on it counterclockwise. It is he who attaches the reel to the trimmer rod. Having unscrewed the thumb, carefully remove the entire coil, trying not to lose the spring inside.

On electric and gasoline trimmers with a straight rod and a gearbox at its end (on such trimmers, in addition to fishing line, you can also install a knife), look for a hole under the coil, insert, for example, a screwdriver into it, quietly rotate the coil until the screwdriver goes even deeper, and the coil will lock. Now we twist the entire coil clockwise (since the thread is left-handed) and remove it from the trimmer. Next we disassemble the coil. It can be assembled using latches or twisted with a lamb. If the coil is on latches, then press on the sides on the base of the latches so that they bend and release one half of the coil body from the other. We just twist the lamb. There may also be a third type of connection of the two halves of such a coil: with it you need to grab the lower part with one hand, and the upper part with the other, and begin to turn them in opposite directions. When disassembling such a coil, you also need to make sure that the spring inside is not lost.

How to Thread Line into a Champion Trimmer

Warranty production of the trimmer's factory refill will inevitably require a line change. Having a very rough idea of what it really is, how to thread the line into the trimmer reel without the help of others, newbies reluctantly take on this task. But with certain abilities, mastering this simple science does not present any difficulties, and a similar abstract presented below will greatly facilitate this common rumor process.

First, to wind the fishing line, you need to remove the reel (spool, spool) from the trimmer - certain steps will depend on the complexity of the configuration and the type of the product itself:

small electronic trimmers with a working arrangement of the motor and coil at the bottom, you have side buttons on both sides of the reel. When you press there simultaneously, the upper part of the reel, together with the internal contents for winding the fishing line, is disconnected, although the lower part remains on the trimmer. It is better to disassemble the bobbin on a flat, smooth place so that the spring included in the structure does not jump out or get lost;
electronic and gasoline trimmers with a curved rod without the ability to install a knife, you have reels with a special wing: in similar designs, you should hold the spool in a stationary position with one hand, and with the other turn the wing nut that locks the bobbin on the rod counterclockwise. After disconnecting the nut, the entire bobbin is removed.
electronic and gasoline trimmers with the ability to install a knife on a straight rod (for example, STIHL trimmers) have a hole under the reel. To keep the rod stationary, a screwdriver, or another suitable object, is inserted into this hole, and with a slow rotation, such mutual placement is achieved when the screwdriver goes inside the hole and the reel is fixed. After which the coil body is rotated clockwise (with a left-hand thread) and removed from the trimmer.

For both cases, a fishing line 2-3 m long is taken. In single-groove reels the fishing line is pulled into a through hole, its ends (tendrils) are folded together and aligned, then they are wound in the opposite direction of rotation of the reel on the rod - the correct direction of winding is usually indicated on the inside by an arrow. If there are locking grooves, the ends of the fishing line are threaded there, or, in other words, held with the fingers of your free hand, threaded through the through hole of the outer half of the reel, the spool is locked and attached to the trimmer rod.

The difference between winding fishing line in two-groove reels is that first a piece of fishing line 2-5 m long is folded in half (to determine the middle fold), and the fold loop is inserted into a special groove between the grooves. Both antennae of the fishing line are wound along their own groove; fixing the antennae and assembling the reel is similar to the option discussed above with one groove.

The first time you complete this process, it will seem long and quite labor-intensive, but with the passage of time and experience, this problem will be solved much faster and easier.

The video below will clearly show how to thread the fishing line into the trimmer reel and wind it correctly - this operation is not difficult at all and, with some patience, will certainly be crowned with success:

There is a type of reel where an automatic mechanism produces winding without the help of others - the user only needs to thread the line correctly. The fishing line is passed through a hole on the inside of the body, its tendrils are threaded through the hole on the outer body without winding, the bobbin is assembled, and when the winding button is rotated, the fishing line inside is wound independently. In such a bobbin it is impossible to wind it by mistake: the mechanism itself will determine the correct direction, since it can only rotate in one direction.

Option

In this embodiment, the head is screwed onto the gearbox shaft. To remove it, you will need to fix this shaft. To do this, similar trimmers, for example, Huter and Champion devices, have a hole through which you can insert either a thin screwdriver or a metal rod.

So, to remove the bobbin, follow 2 simple steps.

Insert a screwdriver into the hole and lock the shaft.
Grasp the head housing and begin to twist it clockwise. You should twist in this direction because the threads cut on the shaft are left-handed.

Preparation - remove and disassemble the spool

In most models of electric and gas trimmers, you will need to remove the spool to change the fishing line. The FUBAG tool allows you to skip this step. To make the instructions universal, we will still look at it in detail:

Lock the shaft. Insert the locking element into the corresponding hole. It can be a thin screwdriver or a metal rod.

Unscrew the spool housing. In our example - strictly in a clockwise direction.

Unscrew the cap in accordance with the direction indicated on the housing.

The preparatory stage has been completed. You can proceed to winding the fishing line.

How to change line in a trimmer

The trimmer is the most common unit used for cutting grass and cutting small bushes. This device is distinguished by its ease of maintenance, simple operation during operation, and thanks to its low weight, even women can handle it. It is no secret that in order to perform high-quality grass mowing work, the correct selection of cutting tools is required. As a last resort, trimmers use special cutting attachments (discs, knives) or trimmer heads with fishing line inside. Attachments and fishing line are consumable tools, but if the knives can be sharpened, then when the fishing line is used up, it needs to be replaced. In this article we will tell you in as much detail as possible how to properly replace the fishing line.

Cord breaks

If the fishing line often breaks, this may be due to the following reasons:

there are stones, small branches and other solid obstacles in the grass;
the user mows the grass close to the fence, and if it is mesh, then this breaks off the “tendrils” even faster;
poor quality cord (it is recommended to purchase a quality one);
The outlet holes in the mowing head are worn out, causing the line to rub against the sharp edges of the bushings and break off (a complete replacement of the part will be required).

The fishing line flies out

The reason that the cord unwinds after starting the unit can also be a weakening of the spring inside the head. In addition, there are cases when, when the unit is turned on, the mowing head flies apart and the spring installed in it is lost. Inexperienced users do not notice the absence of a spring and assemble this unit without it. Therefore, the cord does not hold and flies out under the influence of centrifugal force.

Trimmer coil structure

Mowing heads for trimmers come in a variety of designs, some simple and some complex. The figure below shows a semi-automatic trimmer head from a Husqvarna brush cutter (Husqvarna) disassembled.

This type of head is present in most gas mowers and electric trimmers, such as STIHL (STIHL), Patriot (Patriot), Champion ( Champion ), Bosch (Bosch), Huter (Huter) and others. The design of the mowing head is quite simple. It includes the following parts:

mowing head base;
button for semi-automatic cord feeding;
bobbin (reel) into which the fishing line is threaded;
spring;
eyes - through them the fishing line comes out;
trimmer head cover;
fishing line (cord).

There are also simpler trimmer heads, shown in the following photo.

All these attachments do not allow you to change the length of the fishing line in semi-automatic mode (after pressing a button). If the cord breaks, you have to stop the mower and change it manually.

Line does not automatically extend

If, when you lightly hit the trimmer coil button on the ground, the line does not lengthen, then the reasons for this may be the following.

Option 1 - biting occurred, i.e. clamping the cord between the turns. This problem usually appears if the user winds the line onto the reel unevenly, with intersecting turns, or winds it with insufficient tension. In the latter case, when the mowing head rotates at high speeds under the influence of centrifugal force, the cord begins to tighten, resulting in possible inter-turn clamping of the fishing line. To fix the problem, you will have to disassemble the reel on a trimmer and rewind the cord correctly, that is, in even turns with good tension.

Option 2 - the ends are too short and protrude from the head. The line may not come out when it hits the ground if its ends protruding from the head are not long enough (short). In this case, the centrifugal force is not enough to the line . Therefore, you need to stop the unit (turn off the engine or unplug the electric trimmer) and pull out the line manually, after pressing the button.

Option 3 - the fishing line is soldered inside the mowing head. This causes the reel to lock and not spin when the button is pressed. Basically, this happens for several reasons: poor quality of the cord, overheating of the reel during prolonged operation of the unit, impact of the fishing line on hard objects.

In the first case, the cord from third-party manufacturers may be made of low-quality and fusible materials that cannot withstand mechanical and temperature loads. Therefore, preference should be given to “branded” fishing lines.
But, if you nevertheless purchased a fishing line of unknown quality, and it often gets soldered during operation, then you can follow the example of some users who, after threading the cord into the reel, moisten it with either silicone grease (from a can) or mineral oil. This procedure greatly reduces the likelihood of soldering turns of fishing line together.
Also, the fishing line can become soldered if, during mowing, it hits a hard object (stone, fence, dry branch, etc.). As a result of this, it stretches a little and is pulled back into the head at high speed. The cord heats up due to friction, and its turns stick together. The only thing that can be done to eliminate this problem is to open the trimmer reel and rewind the line.

How to remove and disassemble the coil

Before starting the process of replacing the cord, trimmer users need to remove and disassemble the reel. Let's look at how to do this.

The trimmer's mowing head consists of several parts: a casing, a spring (not in all models), a bobbin with cord and a cover.

Attention! Before you begin any maintenance work on the electrical unit, it must be disconnected from the network.

Trimmers most often use 2 options for mounting the mowing head.

DIY trimmer coil repair

A trimmer, be it gasoline or electric, is the only correct solution for cutting grass in hard-to-reach places that a wheeled lawn mower cannot handle. Trimmers use metal knives or a special fishing line as a cutting tool, which is threaded into the trimmer reel. But, unfortunately, trimmer heads become unusable over time during use. Some problems can be fixed with your own hands, while others will require a complete replacement of the mowing head.

Line winding algorithm

Depending on which trimmer model is used, the type, thickness and length of the fishing line is selected. The cord diameter can be from 1.2 to 4 mm. It is not difficult to guess that the thicker you thread the cord, the tougher and thicker the grass it can cut.

In most cases, a universal fishing line with a diameter of 2 mm is used.

In order to find out what diameter line can be used on your mower, there are 3 ways.

See information about cord thickness in the instructions for the device.
Look at the bobbin itself. Information about possible fishing line diameters can be printed on it.
Insert the line into the outlet hole. If it easily fits into it, then a cord of this diameter can be used.

The line is wound onto a reel located in the mowing head. Therefore, you need to open it first (this was discussed above). There are 2 ways to wind cord.

Basic coil malfunctions

Users of electric trimmers and lawn mowers often encounter problems with the semi-automatic mowing head. Coil malfunctions can be the following:

the line does not extend automatically;
the cord spontaneously comes out of the reel.

The cord spontaneously elongates

There are situations when a trimmer user notices a very rapid consumption of fishing line. At the same time, he never hit the button on the ground to lengthen the fishing line. The reason that the line spontaneously lengthens, being cut off by a special knife on the casing of the device, may be the absence of a spring in the mowing head. Often, novice users of mowers, trying to load fishing line into the reel, forget to install the pressure spring in the head, or completely lose it when opening the lid, and in the future, do not even suspect its existence.

Also, the line can be extended without using a button if the spring is weakened. If checking the spring has confirmed this fact, then it is necessary to place several washers under it to strengthen its clamping properties.

Features and manufacturers

Anywhere, sloppy, poorly maintained grass looks very bad. Ordinary lawn mowers do not always help to tidy it up. They are very expensive, and even if you have the funds, a serious disadvantage is their lack of maneuverability. A small trimmer can do about the same job. However, it is smaller and cheaper.

High-quality trimmers are produced by those companies that have launched the production of high-quality tools of a different profile. If you don’t understand the intricacies, you can safely choose the following products:

Common mistakes

Although winding line is a very common task, many newbies can wind the line incorrectly. Below are the most common mistakes.

Many people, when measuring thread, think that four m is a lot. Because of this, people often measure less and therefore end up running out of line. Don’t be afraid to measure out too much, because you can always cut off the excess.
In a hurry, some people do not follow the threading grooves inside the reel and wind the thread at random. This leads to the line “flying out” of the reel and can even cripple it.
For winding, you should use only suitable fishing line. This error is more common. It is necessary to look not only at the width and volume of the fishing line, but also at its type. You should not use the first line you come across for winding, which will not meet your goals. For example, there is no need to use a thread on young grass if you need to mow dead wood.
Do not turn on the device until it is completely wound and assembled. Although this goes without saying, some people do this in order to check whether everything is made correctly.
Under no circumstances should you confuse the direction of refueling, because this will overload the engine, and it will soon fail.

It’s entirely common for newbies to make mistakes, so you need to follow the tips given in this article.

How it all works and works

A trimmer is a hand-held tool that allows you to cut green grass with a soft stem and not too thick dead wood. It is lighter than a lawn mower and is carried on a belt rather than rolling on wheels.

Due to its low weight, this device can be moved without problems within one area and between adjacent areas.

Using a lawn trimmer, you can quickly remove unnecessary vegetation. This technique is also used:

mowing plants near houses, along paths and fences;

tidying up the banks of rivers, lakes, and streams.

This functionality allows you to use trimmers:

ordinary people (dacha residents and homeowners);

utility services and management companies;

enterprises and organizations with a large adjacent territory.

To prepare for work, just put the trimmer on yourself using special belts. Then the head of the device is brought closer to the grass and the motor is started. Torque force is transmitted to the bobbin using a rigid shaft located inside a special tube. The head has a cutting part. Her quick movements help cut through grass stems.

To avoid impacts against hard obstacles, trimmers are equipped with protective covers. Motors can be electric or gasoline powered. Besides these parts and the fuel reservoir, a typical design includes:

Line and reel for trimmer CHAMPION

a bobbin ending with a fishing line or a knife;

Final point of instructions

Usually the process of replacing fishing line with a trimmer of a certain model is popularly described by the accompanying documentation.
Another issue is that this documentation is often supplied in a foreign language, because most of the unfortunate lawn mowers are their own. imported products. Meanwhile, there is a much more common, economical method that is beneficial for human health and nature. tidying up lawns with an ordinary farm scythe. Scythe Blade:

Doesn’t “tear” grass trunks,
DOES NOT uproot plants
Cuts neatly

Which in the future is accompanied by abundantly growing greenery, and not the formation of dead wood as a result of the trimmer's work.

Recommendations for selection

Electrical devices are connected to home electrical networks with a voltage of 220 V. They cannot do without a carrying device that is plugged into a relatively close outlet. This solution is definitely not suitable for cleaning a large lawn or remote areas in a personal plot. But electric trimmers are silent and do not emit harmful emissions into the atmosphere. The handles are easily adjustable in height, and consumers can install exactly the knife they need.

However, we must remember that an electric trimmer cannot be used in wet weather or for cutting wet grass. In addition, you will have to constantly make sure that the cutter does not touch the power cord. As for gasoline devices, they are heavier than their electric counterparts. In many ways, this disadvantage is compensated by increased maneuverability and greater productivity. With such a tool, you don’t have to worry about power interruptions or blackouts, and even work where there is no power supply at all.

Changing blades on a gasoline trimmer is no problem. This is a reliable and comfortable device. Its performance is sufficient even for commercial applications.

But this technique creates quite a lot of noise, and therefore you have to work with protective headphones. And the inconvenience for other people cannot be ignored either.

To tidy up the ground near the house, home lawns, flower beds and gardens, you can limit yourself to trimmers with a power of 0.5 kW. If the electric motor is located at the bottom, the design is simplified and lighter. However, this increases the danger when coming into contact with wet objects. The structure of the bar cannot be ignored either. If it is made according to a straight line, then the trimmer will be more reliable and efficient.

Of the individual models worthy of attention:

What is a trimmer?

The base of this equipment consists of the following elements:

An engine whose main function is to rotate the cutting head at the end of the rod;
Specifically, a head consisting of a reel on which either a fishing line or a knife can be wound;
Knives or fishing line spinning at high speed, which are the main cutting part of the device; how to load the fishing line into the trimmer will be discussed a little further.

An electronic device is inferior in power to a gasoline device, so it is perfectly suitable for working on a standard plot of land adjacent to a house with a source of electronic energy. The main positive aspects of such equipment are the absence of noise during operation, light weight, ease of operation and, of course, environmental friendliness.

READ How to Test Trimmer Magneto

As for gasoline trimmers, such equipment, of course, is more mobile, so it can be safely transported from place to place and get rid of annoying vegetation in any area. There is absolutely no need to use electricity here, which has a positive effect on the functionality of such a device - the cutting attachments can be changed when working with a wide variety of weeds.

One of the most common attachments is a fishing line, so you should apply the brakes more carefully on this element.

Possible causes of problems with electric streamers

When using a trimmer with an electric motor installed, problems with speed also occur. But they are caused by completely different problems compared to fuel spits. The electric motor does not develop the required rotation speed in the following cases:

if the voltage in the supply network is below the rated value for the electric motor by more than 10%;
in case of problems with the soft start system (if this unit is installed);
when there are problems with the brush assembly;

To eliminate a voltage problem, you need to use a multimeter or tester to check its value in the outlet from which the electric braid is powered. If it is less than the minimum permissible value, then to increase it you will need to turn off all electrical appliances or install a stabilizer.

A prerequisite for normal operation of the trimmer is the use of an extension cord with a core cross-section corresponding to the power of the scythe engine.

To repair the soft start unit, you will need to have appropriate knowledge of electronics, so it is better to contact a service center. There they will determine whether it is repairable or whether it needs to be replaced. You can check the button yourself or find a block diagram and try to figure it out.

The brushes may wear out, resulting in loss of contact, which leads to the motor stopping. The brushes are easy to replace. The features of the process are determined by the model of brush cutter used. At the same time, you will also need to clean all contacting surfaces.

If the windings burn out, if you continue to mow grass or bushes, the electric motor will quickly burn out. This will be accompanied by the appearance of a burning smell, up to the melting of individual parts. The electric motor will need to be replaced.

Wedging of rotating parts occurs for various reasons. To identify and eliminate them, you will need to sort out the drive unit. There are models in which the number of revolutions is automatically adjusted depending on the load, increasing as it increases - their rotation speed drops at idle.

The video shows an algorithm for identifying the most common reasons why the trimmer does not reach the required speed:

Use of low quality fuel

The trimmer does not develop speed if it is filled with low-quality fuel. For this reason, the engine may not start at all or may run jerkily, changing the speed of rotation of the knife or fishing line.

To independently determine the quality of the gasoline used, perform the following steps.

Use a special wrench to remove the spark plugs.
Their working contacts are inspected for the presence of a red brick-colored coating: if there is one, then the fuel used contains significant inclusions of additives.

In general, spark plugs often act as indicators that help determine problems with the combustion chamber of a gasoline engine, because they can be quickly removed and inspected.

If deposits are detected, it is necessary to drain the fuel poured into the tank and replace it with high-quality fuel. The lawn mower used should only be filled with the grades of gasoline specified by the manufacturers in the operating instructions. It is also necessary to clean the spark plugs from deposits before reinstalling them.

Common reasons for trimmers running at low speeds

The problem when the lawn mower does not pick up speed occurs mainly with gasoline units. This affects equipment of various models, for example, Husqvarna, Champion , STIHL.

With high-quality products, such problems occur less frequently than with cheap ones from unknown manufacturers.

Some of the structural elements that may cause problems can be visually inspected, but to check the functioning of the remaining components, you will need to disassemble the lawn mower.

Engine problems

If everything is in order with the fuel, filters and spark plug, then the next source may be a gasoline engine. It may have the following mechanical failures:

problems with the carburetor;
problems with the engine drive mechanism.

There is a small cable in the carburetor section. It may subside and lead to the problem in question. Therefore, when working on a carburetor, you should first check the condition of the cable and, if necessary, tighten it (but not to the limit). The main thing is not to overdo it with tension, so that it does not crack under load.

Afterwards, you need to check the operational settings of the carburetor, which must correspond to the parameters given in the instructions. If they are installed correctly, but there is no desired effect, then you should disassemble the part, rinse, clean, blow through all its strokes with a pump and put it back together. The carburetor itself must be free of mechanical damage.

If it is impossible to restore the carburetor's performance on your own, it is better to replace it with a new part or resort to the services of professionals.

If adjusting or replacing the carburetor does not give the required result, it is necessary to clean the drive mechanism and lubricate the cable located inside it with oil.

READ Fuel Consumption Per 1 Hour of Trimmer Operation

You can fix problems with the engine yourself if you have the required skills, but it is better to use the services of a service center for this. Its specialists will conduct a comprehensive diagnosis of the trimmer and determine the exact cause of the drop in speed.
