Some tricks for working with a gas trimmer

Summer time has arrived, and lawn mowers are making their usual noise in the garden plots. Great tool, powerful and mobile. Using a gasoline trimmer, you can mow the grass and get rid of dried weeds. However, there are times when the lawn mower does not start, operates intermittently, or does not develop full power. There is certainly no time for work here! And as they say, you pull the starter handle more than you mow.

Difficulties with starting arise not only for seasoned lawn mowers, but also for new ones. What to do in this situation? There is only one way out - listen to the advice of experts and take advantage of their practical experience!

For what reason does the Shtil electric scythe not develop full power?

When using an electric trimmer, RPM problems may also occur. Here the reasons are completely different than for fuel streamers.

You can troubleshoot problems yourself

Shtil electric trimmer

The electric trimmer does not develop the required power because:

the network voltage is below the required minimum for the device by more than 10%;
there was a failure in the soft start (if such a system is available);
there is a malfunction of the brush assembly;
the motor winding was burnt;
rotating parts sometimes jam.

To adjust the voltage, you should first check its power. If it does not meet the standards, it should be increased using a stabilizer.

Repair of the soft start system is carried out only at a service center.

Note! When the brushes wear out, you simply need to replace them. When installing new ones, it is recommended to clean all surfaces with which they come into contact.

To adjust the voltage, you should first check the power.

If the motor windings burn out, you need to change the electric motor.

Jamming of rotation parts can occur for various reasons. To eliminate them, the entire drive assembly must be reviewed.

For your information! The last problem may also arise with another unit from this company - the Shtil pruning shears, and sharpening the disc with scissors will be the solution.

FS 130

The model is a professional model, so the goals set for him will be a little higher. It is designed for mowing coarse grass, cleaning tough bushes and young trees.

It features the latest high-power engine that does not emit large amounts of harmful emissions.

The Stihl FS 130 mower costs around $400.

engine power - 1.9 hp;
engine volume - 36.3 cm3;
tank volume - 0.53 l;
rod - straight;
handle - T-shaped;
equipment - shoulder strap, two-blade knife;
line diameter - 2.4 mm;
weight - 5.9 kg.

The range of prices for these models does not indicate any difference in quality; first of all, each Stihl mower is designed for a specific type of work.

It is clear that there is no point in purchasing a more expensive and powerful model if you have a small plot or front lawn. Simpler models will cope with this task perfectly, but the word “simplicity” is not used here in a derogatory manner. More powerful mowers are designed to handle larger areas with overgrown and dense surfaces, hence the price difference. If you are confused by such a variety of tools, then do not be upset, but feel free to click here and we will tell you how to choose a lawn mower for your dacha.

However, no matter what model you choose, you must follow certain operating rules recommended by the manufacturer in order to avoid possible breakdowns.

Why do the trimmer speed drop?

There are a number of different events to this common difficulty. During your time working with the device, there is an opportunity to encounter both obvious problems, the signs of which are correctly traced, and asymptomatic variations. Option 1 is simpler in terms of finding difficulty. If the trimmer does not develop, and there are no clear signs of breakdowns, then it will be necessary to alternately check more common cases of problems, and if a prerequisite is found, remove it.

Features and best models

The mower, which is distinguished by its versatility, reliability and ease of operation, deserves special mention. The company's specialists created many varieties of braids, with different features and applications.

For example, the range of lawn mowers is designed for mowing grass in large areas. For this purpose, a self-propelled wheeled system was developed, with the help of which it became possible to care for a large area without spending a lot of time and effort. A brush cutter is perfect for decorating shrubs, giving them some artistic image and texture.

If you need a more subtle approach to grass cleaning, for example, around flower beds or between trees, then a gasoline trimmer, designed for accuracy and precision, will do the job perfectly. The company's specialists took into account all the nuances and possible difficulties when working with scythes, so they equipped them with nylon strings, which prevent mechanical damage to trees.

A special AutoCut trimmer head is also used, which ensures the normal functionality of the gas trimmer string knives. This article will tell you about the prices for gasoline manual lawn mowers and trimmers, and it will also help you make the right purchase, which you will not regret.

There are two types of these mowers: amateur and professional models, designed to solve problems of a certain complexity. The first category includes models FS 38, FS 45, FS 55, etc. The features and differences of these tools are the motor power (from 0.9 to 1.2 hp depending on the configuration) and tank volume (approximately 0. 34 l).

Professional trimmers include the Stihl FS 130 and FS 250. Let's look at the characteristics and properties using the example of several mowers, in particular the FS 38, FS 70 and FS 130.

Diagnosis and troubleshooting of electric motors

Malfunctions of electric trimmers can be as follows:

insulation failure or cable break;
malfunctions in the cutting tool area;
Damage to the socket or plug.

To cope with these breakdowns, you do not need to disassemble the entire device.

If the engine has serious problems, it will have to be disassembled. To do this you need to unscrew several screws. Having gained access to the engine parts, you need to do the following:

check the degree of wear of the brushes - unsuitable parts will need to be replaced with new ones;
ring the motor winding - the resistance should be high;
check the stator and rotor - to test the rotor winding with a multimeter, measure the resistance: large deviations from the norm indicate a malfunction, the absence of resistance on the stator winding also indicates a breakdown (the stator housing is diagnosed in a similar way).

The Stihl ms 250 chainsaw does not develop speed and stalls when you press the gas.

Problems with low rpm are common with cheap trimmers. However, if not properly maintained, manual mowers such as Huter, Patriot 3055, and Echo also suffer from this.

What to do if the gas trimmer does not pick up speed?

If you once got a trimmer that works with gasoline, then you probably had to deal with the problem of turning on the trimmer, and similarly with the problem that the gas trimmer does not develop.

That is why this article was created.

What should you do if the trimmer , which has been working for you for a couple of years, suddenly just stops gaining momentum, and the engine simply stalls? In this case, we should consider a number of problems associated with stopping the engine.

The engine may stall under various circumstances. At times, the reason for the incorrect operation of a gasoline-powered trimmer is a clogged air filter.

The filter itself is one of the most important events, due to which the work of a gasoline trimmer may end.

Various debris often gets there, dust particles get there, which also clog the filter, so it needs to be cleaned and washed every month, or more often, it all depends on how correctly you can choose the studio, what power the gasoline trimmer has, and how often you use this device.

Immediately after starting

Many owners of garden equipment face the problem of the trimmer engine stopping after it has started. Petrol tool repair technicians are confident that the problem lies in the fuel system, or, to be more precise, in the carburetor. As a result of violation of its settings, uneven fuel supply occurs and, as a result, increased vibration and engine shutdown.

Trimmer ignition module

Another reason why the trimmer starts and immediately stalls is a clogged fuel valve. To restore the circulation of gasoline in the fuel system, it is enough to dismantle the valve and remove contaminants.

The problem may be a malfunction of the ignition module, but in case of such a malfunction it is best to contact a specialized center.

READ Trimmer Gasoline Refill

The unit may stall immediately after starting if the carburetor is misaligned or incorrectly configured - this causes uneven fuel supply. The result of this is that the device begins to vibrate distinctly. To troubleshoot problems, the carburetor is reconfigured following the instructions for the mechanism.

The engine also stops when the fuel supply valve becomes clogged. In such cases, simply cleaning it is enough. If the lawn mower started working at first, but then immediately stalled, then fuel may be supplied to the carburetor unit with some difficulty. Loosening the valve helps solve the issue, which ensures free circulation of the mixture in the system.

A stop can also be caused by air leaks if there is mechanical damage to the hose (holes, cracks) that takes in fuel. In this case, you should increase the drive speed to quickly expel air bubbles from the system.

The trimmer won't start - how to find and fix the problem?

There is a whole list of breakdowns, as a result of which the household trimmer stops starting. In electric and gasoline scythes, the reasons may differ. This is due to differences in the design of electric and brush cutters.

Most often, electric scythes do not work due to problems with the cable. It is possible that as a result of accidental contact of the cutting elements with the wiring, the latter remained broken. In this case, you will need to replace the cable, having first cleaned and insulated the contacts.

Another reason for the breakdown of the electric scythe is the jamming of the protective relay, which is activated whenever there is a short circuit in the network. In this case, the relay must be replaced, otherwise there is a risk of fire in the internal wiring of electric trimmers.

There are many more reasons why a gas trimmer will not start.

Their list includes:

loss of properties by the fuel mixture - if, when storing a lawn mower, there is fuel left in its tank, then the garden tool most likely will not start. In this case, you will need to drain the fuel, blow out the cylinder, add fresh mixture and start the trimmer. The brush cutter also stops starting due to poor quality of fresh fuel, so to refuel the scythe you need to use only gasoline from gas stations of trusted brands;
incorrect proportion when preparing the fuel mixture - in this case, the mower does not start well due to its spark plug being flooded with engine oil. The operator will need to remove, clean and dry the spark plug, then install it back and try to start the trimmer. If this does not help, then the spark plug will need to be replaced with a new part;
accumulation of debris or a malfunction of the air filter - in both cases, the element will not be able to pass the air that is necessary for mixing with the fuel mixture. A dirty filter will need to be cleaned, and a faulty one will need to be replaced;
breakage or deformation of the flexible shaft placed inside the rod - to eliminate the breakage, you will need to remove the gearbox, remove the shaft and install a new one in its place;
muffler malfunction - the trimmer may not start due to clogging or deformation of the muffler. In both cases, harmful emissions will accumulate in the cylinder, which will lead to serious engine damage. To avoid this, the operator will need to replace the muffler as soon as the problem is discovered.

User manual

Particular attention should be paid to how to properly carry out the first start-up and running-in of a gasoline mower. Competent actions will maximize the life of the trimmer and reduce the cost of its maintenance and repair.

Before you start the device for the first time, you will need to carry out several preparatory steps. Their list includes a visual assessment of the condition of the gearbox and the preparation of a high-quality fuel mixture, taking into account what kind of oil should be poured in accordance with the manufacturer’s instructions and recommendations.

It is the composition of the fuel that experts and experienced owners of gasoline trimmers recommend focusing on. In situations with two-stroke engines, unlike four-stroke engines, the components will be gasoline and oil

The proportions are indicated in the relevant instructions supplied with the equipment, or on fuel and lubricants labels. The annotations, among other things, indicate the type of fuel and engine oil recommended by the developers.

After all trimmer components have been inspected and the fuel has been properly prepared, you can proceed directly to its start-up and subsequent running-in of the internal combustion engine. This process includes the following steps:

the lawn mower must be placed in a horizontal plane on the most flat surface possible;

the lever controlling the air damper is moved to the closed position;

using a primer, fuel is pumped to the carburetor (a few movements are enough);

the ignition is turned on by the corresponding switch;

the starting cord should be pulled out as smoothly as possible until resistance is felt;

The device is started by several sharp jerks of the cord;

After the engine has started, the air supply should be opened.

In some situations, the trimmer may not start or may stall immediately after starting. In such cases, you need to slightly open the air supply to the carburetor and try again. After a positive result, you should let the engine run for at least 5 minutes in idle mode.

Using the lever, the air supply should be set so that the reel with fishing line or the knives remain motionless. After the engine has completely warmed up, the damper is opened by moving the mentioned lever to the position marked with the ON icon, and the gas regulator is half-clamped for 20-30 seconds. In the next step, the trigger is released and the trimmer idles for approximately 40 seconds. Similar manipulations are repeated for 10-15 minutes, after which it is necessary to take a 20-minute break.

By repeating the above steps, further running-in of the internal combustion engine of the gasoline mower is carried out. The next stage is running in the gearbox, for which you will need to select an appropriate area with soft grass. The latter is mowed for 5-10 minutes with periodic gas boosts (1/2 - 2/3 of maximum speed). This cycle is repeated several times at intervals of 20-25 minutes.

Sooner or later, trimmer owners have to face the need to change the fishing line. This is an integral part of the operation of such equipment. There are several ways to update the cutting element in question. The simplest option involves the following manipulations:

remove the head from the trimmer and clean it thoroughly;
unwind the required length of fishing line (recommended 2-3 meters) and bite it off with wire cutters;
bend the fishing line so that one end is 15 cm longer than the other;
place the bend on the spike located between the grooves of the reel;
wind the fishing line simultaneously in two directions, temporarily fixing it in the grooves (the direction of winding is indicated by the arrow);
pass the ends through special holes in the lid;
insert the reel with the new line into place and snap it into place.

Often, during the operation of a Stihl lawn mower, it may be necessary to adjust the carburetor. If you have the appropriate knowledge and skills, you can do it yourself. At the preparatory stage, you will need to thoroughly rinse the air filter. It is worth noting that this is highly recommended to be done every ten hours of operating the mower.

The setting is carried out with three screws, one of which is responsible for the fuel supply. It is tightened until the internal combustion engine begins to stall. Then you should unscrew the screw a quarter of a turn (if the engine has stalled, then 1/2). After starting the trimmer, continue to unscrew the same screw until the internal combustion engine begins to operate stably at higher speeds.

Which is better - STIHL or Husqvarna

If we objectively analyze the reviews of the owners of Shtil and Husqvarna lawn mowers on different forums, we can draw a general conclusion that these models are approximately at the same technical level in terms of reliability. But, if we compare lawn mowers in terms of safety and convenience, some consumers prefer the Husqvarna brand.

Husqvarna 545Rx brush cutter

The guard on the Husqvarna brush cutter is larger in size, the engine is completely covered with plastic, the unit starts up more smoothly and picks up the required speed more smoothly. All components are optimally easy and quick to repair.

Calm starts worse, its sound is sharper, and the color of the plastic gets dirty. At the same time, Stihl lawn mowers use maintenance-free gearboxes that do not require additional lubrication. Husqvarnovsky must be lubricated, only then a long service life is guaranteed. The Stihl piston group can withstand a not very high-quality fuel mixture without breaking down.

Husqvarna 325Rx brush cutter

A big plus of STIHL trimmers is the ergonomic vibration-damping pads, which you can work with for a long time without discomfort. The fuel consumption of STIHL lawn mowers is 20% lower, and the emission of harmful substances into the atmosphere is 70% less. They note that the always-on ignition on Husqvarna is, in fact, a serious disadvantage, based on safety precautions.

More complex reasons for lawn mower failure

If the step-by-step troubleshooting algorithm does not produce results, and your scythe still does not start or stalls, it is worth inspecting the carburetor and the engine itself. A clogged carburetor can be one of the reasons for unstable operation of the tool. There are three main problems here:

Clogged channels or jets. All this is cleaned with special washes or blown with a powerful jet of compressed air from a compressor. Do not use needles or wire, as the bores may be damaged;
Worn carburetor gasket. The solution is to replace the failed gasket;
Violation of tightness. To check this indicator, you can use a regular household tonometer, replacing the pressure gauge with a suitable one. Keep an eye on the readings: if they do not change, everything is fine, but if the pressure starts to drop, it means that some part of the carburetor is faulty. You'll have to find it and replace it with a new one.

If everything is in order with the carburetor, then the gasoline trimmer may not start due to wear on the piston group. If chips, scratches or burrs are found on the piston or cylinder, they should be replaced. Piston rings must be checked. A slight luffing of the piston when the connecting rod swings indicates that it is time to change the rings. This procedure is best left to the service center specialists.

Problems starting the engine

Correctly identifying the cause of the failure is very important, because otherwise we simply cannot eliminate it. If there are no extraneous sounds when trying to adjust the chainsaw (knocking, grinding, etc.)

D.), It often turns out that in fact there are no problems. For example, if you start the chainsaw incorrectly and pull the fork for a long time, the engine simply fills up and starts very strong.

To properly start the chainsaw engine, set the lever or switch to the flap position. Then you need to pump the mixture into the carburetor if you have a fuel pump. Pull the crank handle out until the motor resistance becomes noticeable, and pull the amplitude vigorously while holding your hand to the side. After two. three such movements, the engine must first start, and then decay. If this does not happen, then you need to move the lever to the half-throttle position or simply to the working position, and then continue to operate the chainsaw in this mode. Many half-throttle chainsaws lock automatically when you pull the choke

Some models have a keyed ignition, it is important to make sure it is turned on

If the engine does not start, the first thing to do is. unscrew and check the spark plug. There are times when a plant fills the burner with fuel during the cold season. Then you also need to unscrew the spark plug, dry the combustion chamber with one plant, clean the spark plug, screw it in and restart. It is advisable to immediately check for a spark. on the twisted spark plug we put on a cap with a high voltage wire, we put it on the cylinder and we pull the starter. Visually observe a frequent blue spark. OK. We twist the candle into place and fire it up. If there is no spark, change the spark plug and try again. Again, no. Check the connection of the high voltage wire to the spark plug, coil and ignition system.

In general, the condition of the spark plug can be used to determine the type of fault.

Dry. Most likely the fuel mixture is not entering the cylinder. This is not an ignition system, so the spark plug is screwed in and checked.
Wet, heavily splashed with fuel. The cause of an excess fuel mixture is a violation of the starting rules, as described above, or an incorrect carburetor setting.
Covered with black carbon. This may indicate the use of low-quality oil, an incorrectly adjusted carburetor, or an incorrectly calculated ratio of gasoline to oil. The spark plug should be washed, cleaned of carbon deposits with a sharp object (an awl or a needle), wipe the electrodes with a cloth and put them in place.

Trimmer Stihl FS 55 Brushcutter Does not develop speed, stalls, we are sorting out the carburetor

When checking the spark plug, you need to pay attention to the gap between the electrodes: the normal is considered to be from 0.5 to 0.65 mm. Damaged or worn gasket should be replaced

A properly adjusted carburetor chainsaw ensures its efficiency at full power with the most economical fuel consumption.

The need to adjust the carburetor chainsaw is infrequent, since the adjustment is initially performed by the manufacturer to achieve optimal operating mode. The adjusting screws are designed to allow more precise adjustment of the carburetor chainsaw, if necessary.

When and why is this needed?

Among the reasons for the failure of fixation of the adjusting screws, the most common are the following:

Strong vibration or damage to the protective cap. This happens rarely, but it does happen.
Serious engine (piston) wear. Of course, in this case it is better to take care of repairing the chainsaw, but at the same time, adjusting the carburetor can improve its functionality for some time.
Litter in the carburetor due to low quality gasoline or due to scale formation. In this case, in addition to adjusting the carburetor, it can be avoided.

Strainer in carburetor

The last possible place for a blockage to form is the strainer in the carburetor. The diagram below shows the number 13.

To clean the strainer, you need to remove the carburetor from the Windshield 180 chainsaw. The job begins by removing the top cover of the saw, after which the two nuts are unscrewed using an 8mm socket. In addition, it is removed from the filter housing guides, after which the choke rod and the engine control lever are disconnected. Finally, the fuel hose and throttle body are disconnected and the carburetor can be removed from the guides.

The carburetor filter is installed in the fuel pump chamber; to achieve it, one screw securing the pump cover is loosened and removed along with the gaskets.

Clean the mesh filter, you can only use compressed air. Any mechanical methods are strictly prohibited because the mesh is very soft and easily changes shape. It creases easily when you push it, and there are curves on the edge of the seat that prevent filtered fuel from getting into the carburetor.

During the cleaning process, the seat with the filter installed in it should be half-closed with your finger, and then only blow air, otherwise the mesh may fly away and can no longer be found.

About the carburetor design

The carburetor serves to mix the flammable mixture with air while maintaining predetermined proportions. If clear doses are not followed, the proper operation of the engine is at risk. When a huge amount of air enters during mixing of the components, but there is not enough fuel, then such a mixture is considered “lean”.

Oversaturation should not be allowed, because with a larger amount of fuel compared to air, malfunctions or engine wear are also likely. Carburetor adjustment is needed not only before initial use, but also when any differences in its operation are detected. Before working with a chainsaw, do not forget to run it in.

Carburetor components

The carburetor design contains a standard set of parts, but may vary little depending on the manufacturer. Components:

The basis. This is a special tube that is visually similar to an aerodynamic design. Air passes through it. In the transverse direction, a damper is located in the middle of the pipe. Its position can be changed. How to adjust the carburetor on How to change the piston on the Trimmer. The more it is extended into the passage, the less air enters the engine.
Diffuser. This is the constricted part of the tube. Here's what it looks like on how to adjust a carburetor on a chainsaw to set it up. With its help, the air supply speed increases precisely in the segment from which the fuel comes out.
Channels for fuel supply. The fuel mixture is contained in the float chamber, then passes into the nozzle, from which it flows into the atomizer.
Float chamber. It is a separate structural element, reminiscent of the shape of a tank. Designed to constantly maintain the optimal level of fuel fluid before entering the channel from which air enters.

Step 2

Install the plate with the manual fuel pumping button and tighten the four screws.

The carburetor is assembled and ready for further use.

Repairing a lawn mower carburetor may seem like a complicated process for the first time, but if you have to disassemble it a second time, this procedure will not cause any particular difficulties.

If you do not find any of the listed problems in your carburetor, it is recommended to seek help from a specialized service.

Step 3

They have the ability to wear out during use. From prolonged use, they become deformed, stretch, lose elasticity, low-quality fuel corrodes them, and can no longer perform their functions well. This also applies to the needle itself. The fact is that it is covered with a thin layer of rubber, which wears out during operation and can no longer fit tightly into the hole. The lawn mower begins to work intermittently. To eliminate such a breakdown, it is necessary to replace all worn parts. Where can I get them?

It includes two diaphragms, a gasket, a needle valve and a spring.

All carburetor wear parts can be replaced. Therefore, you should not rush and buy a new one, and you also don’t need to run to the workshop; repairs can be done by any user of a brush cutter. Professionals claim that the quality of the components in the repair kit even exceeds the characteristics of the original carburetor parts. Therefore, a high-quality repaired unit will work better than a new one.
