Husqvarna chainsaws (Husqvarna): features, main breakdowns and solutions to them, popular models

Husqvarna is the favorite saw manufacturer on the market today. It produces gasoline-powered tools that can be used for personal and professional purposes.

The manufacturer started producing chain saws in 1920. Since then, he has introduced to the market noteworthy and modern developments that impress with their highest quality. At first, all Husqvarna tools were made in Swedish factories, but now the company’s facilities are also located in Brazil, the USA, France, China, and Poland.

Information about whether you have a Chinese chainsaw or an analogue from another country can be found on the manufacturer’s website. But it is worth considering that all products undergo complete quality control.

Husqvarna chainsaw design:

  • new type of engine;
  • comfortable handles;
  • strong bar with saw chain;
  • noise suppression system during sawing;
  • right hand protection;
  • two plastic tanks for fuel and oil;
  • body resistant to any load.

Adjusting the Husqvarna chainsaw carburetor

If the required power is not obtained, you need to adjust the carburetor on the Husqvarna chainsaw. This procedure can be carried out at home using screws H, T, L.

First launch of the Husqvarna 135 saw

Setting up the Husqvarna chainsaw carburetor occurs in the following sequence:

  • First, warm up the tool’s motor by turning it on for 5 minutes.
  • Then turn screw L until the maximum speed begins.
  • Then immediately turn the screw in the other direction a quarter turn.
  • Press the gas trigger and hold it in this position for 10 seconds. Immediately turn screw H a quarter turn.
  • Release the gas and turn screw T clockwise.
  • When the chain begins to rotate, the screw must be turned back until the bar stops.

After these manipulations, the Husqvarna should begin to gain momentum and work perfectly.

Chainsaw Husqvarna 440

The tool cuts down small and medium-sized trees. It can be used to harvest wood for the winter. The intelligent design ensures smooth and safe operation of the saw.

The Husqvarna 440 chainsaw has the following properties:

  • engine power – 2.2 l. With;
  • the tire has a size of 40 cm;
  • fuel tank – 370 ml;
  • lubricant reservoir – 250 ml;
  • weight – 4.8 kg.

Replacing a sprocket on a Husqvarna chainsaw

If the saw does not start or begins to stall when reaching high speeds, it means the clutch is worn out. Its repair consists of completely replacing the mechanism.

  • Remove the air filter and spark plug.
  • Next, you need to remove the sprocket from the Husqvarna and look for any blockages.
  • Unscrew the clutch coil and remove the pressure washer.
  • Next, install a new clutch and replace the sprocket.

Finally, assemble the mechanism and test the saw. If the parts were installed correctly, the tool will simply gain momentum. But it is worth considering that at first the operation of the device will be accompanied by hums. They will end when the asterisk is one hundred percent in its place.

Chainsaw Husqvarna 555

A semi-professional model that is used in the garden and in sawmills. She quickly saws through large pillars and can prepare firewood for the winter. There is an inertia brake and a vibration damping system.

chainsaw has the following properties:

  • power is 4.3 liters. With;
  • the tire has a size of 50 cm;
  • fuel tank – 650 ml;
  • oil tank – 330 ml;
  • weight – 6 kg.

Gasoline to oil ratio for Husqvarna chainsaw

Any model runs on a fuel mixture that consists of oil and gasoline grade over 90. Fuel for a Husqvarna is mixed in the following ratio:

  • for products with a capacity of less than 2 liters. With. it is necessary to mix gasoline and oil in a ratio of 1:40;
  • for tools with power above 2 HP. With. combine gasoline and oil in a ratio of 1:50.

Husqvarna chainsaw stalls when pressing gas

You need to inspect the spark plug and repair or replace it. The cause of the breakdown lies specifically in it or in the cessation of fuel supply.

  • If the spark plug is wet, it means the carburetor has failed. It needs to be diagnosed and adjusted.
  • If there is no fuel supply, inspect the entire fuel system and its hoses.

Why it won’t start and what to do

Among the malfunctions of the Husqvarna chainsaw are poor engine starting. The engine either cannot be started at all, or it starts poorly.

There is no clear answer to the question why the chainsaw won’t start. The main assembly unit of the tool is the engine. The following conditions affect the stability of operation:

  • fuel mixing;
  • air;
  • presence of a spark;
  • lubricant

Each factor is responsible for its own working unit:

  • for the fuel mixture - carburetor;
  • for air - a cleaning system, in particular an air filter;
  • for the spark - the ignition mechanism and spark plug;
  • lubrication - lubrication system and gasoline.

A common reason why chainsaws do not start is failure to follow the starting algorithm. The engine unit should only be started after all parts have been completely assembled:

The chain brake is always on. To avoid losing control of the instrument, you must not start in the air.

Starting the engine in a cold state is done as follows:

  1. Place the tool on the ground, step on the back handle with your right foot, and place your left hand on the front handle.
  2. The saw is in a stable state, the chain does not touch the ground.
  3. With your right hand, take the starter handle and pull the cord, but do not twist it around your hand.
  4. As soon as the first flash occurs, return the choke lever to its initial position, opening it, and repeat the start.
  5. They gas it and let it go. The blocking is disabled.
  6. The engine is switched to idle speed by quickly turning off the gas limiter.

Starting a warm engine is carried out in the same sequence, but without opening the damper.

If the start is made correctly, but the engine does not work, a possible reason is the lack of fuel in the tank, or the carburetor fuel chamber is not filled. Check the tank and chamber, fill them with the mixture.

If the ignition system malfunctions, inspect the spark plug and check for the presence of a spark at the electrodes. If it is wet (gasoline floods the spark plug) and a spark is not detected, the part is turned out, dried or replaced. If it is dry and there is a spark, then there is a problem in the fuel equipment - clogging, depressurization of the gas intake.

Magneto malfunctions are also confirmed by a weak spark. Despite the ignition operation, there may be no flash in the cylinder, while the spark plug removed from the cylinder is wet. The solution is to purge the cylinder with the carburetor flaps open.

The electrodes of the system are covered with soot or oily. This can be removed with a wire brush. The spark plug is washed and cleaned by allowing the gasoline to evaporate.

Violation of the gap between the side and central electrodes leads to a poor start. The normal interval is 0.6-0.7 mm. It is adjusted by hemming.

If the ceramic insulator surrounding the central spark plug or the current-carrying core of the wire is damaged, replace it.

If it starts and stalls

The Husqvarna chainsaw starts and stalls when you press the gas. This is caused by a clogged carburetor jet and a dirty fuel tank filter. The defect is eliminated as follows:

  • disconnect the fuel hose from the carburetor;
  • inspect the fluid leakage - the breather is clean if a full stream comes out.

The next reason why a chainsaw stalls is contamination of the muffler with exhaust resins. The issue can be resolved by cleaning.

Wear of piston rings affects the operation of the cylinder-piston group. If there is play during inspection, parts are replaced.

When starting the engine, the unit may also stall:

  • as a result of water entering the mixture;
  • due to poor chain lubrication;
  • oil wire leakage;
  • clogged channels.

Pay attention to the chain:

  • if dryness increases, clean the oil supply channels, inspect the elements connecting the fittings to the tubes;
  • If there is an oil leak at the connecting points or there are cracks in the tubes, they are sealed with sealant.

The engine does not develop speed:

  • if the piston rings burn in the grooves;
  • when the crankcase rubber seals wear out and lose elasticity;
  • leaks in the connection between the cylinder and the crankcase;
  • due to incorrect setting of the ignition timing;
  • as a result of contamination of the cylinder fins and fan grille;
  • under heavy load immediately after purchasing a new engine.

How to start a chainsaw correctly: instructions

Let's look at the main steps that must be followed in order to start the STIHL chainsaw correctly.

  • Before starting, the chain brake must be activated. It is activated by pressing it forward (as shown in the photo).
  • Remove the protective cover from the tire.
  • If the model has a decompression valve, it should be set to the on position, which will make it easier to start the tool’s motor.
  • Press down on the fuel pump to reduce the number of pumps and make starting easier.
  • The combination lever must be turned on in cool start mode. To do this, you need to lock the gas lever and push the combination lever all the way down.
  • Before starting the system, you need to ensure a level surface. In this case, the cutting part must be at a distance from the ground, otherwise it will become dull when starting.
  • Take the tool with both hands, while keeping it on the ground. The left hand should be on the chainsaw handle, and the right hand should be on the starting cable. Secure the tool with your right foot by stepping on the rear handle.
  • Gently pull the starter cable with your right hand until you feel strong resistance. Using force, pull the starter rope a couple of times, starting the engine briefly. With all this, in order to avoid abrasion, it is recommended to pull the cable upwards from the body.
  • After a short start, the engine stalls. Now move the combination lever up one click. The lever should take the half-throttle position.
  • Pull the starter rope again to start the chainsaw engine.
  • When the engine is started with a small press of your finger, operate the throttle lever. The combination lever will automatically be switched to idle speed.
  • Without touching the gas lever, move the chainsaw.
  • Pull the handle towards you to release the chain brake. The position of the left hand remains unchanged, the hand is on the handle. The chain will be unlocked after the appropriate click.

What to do if the chainsaw does not start?

But what to do if all the steps specified in the operating instructions have been followed, but the chainsaw still does not start? Regardless of the manufacturer of the chainsaw - STIHL, Husqvarna, Partner, Ural, Druzhba - a number of general activities can be identified for the tool factory.

Below are practical tips from professionals that have been tested in practice and have proven effectiveness:

  • Don't be nervous and don't try to adjust the chainsaw's carburetor.
  • Set the instrument aside and let it rest. The reason may simply be that the candles are flooded. Give them a chance to dry.
  • Take the instruction manual. Try starting the saw again. There is no need to turn on the saw brake.
  • If this does not help, try removing the cover from the chainsaw body and removing the air filter. This way you can check the cleanliness of the filter and at the same time make the starting process easier.
  • Replace the spark plugs. If it is not possible to install new spark plugs, you can use the old ones by first removing and calcining them.
  • If a strange, pungent odor appears, it means that excess fuel has entered the chainsaw engine. To correct this situation, you need to remove the spark plug and, turning the saw over with the hole down, drain the excess. Without returning the saw to its normal position, sharply pull the starter several times. This way you will ensure that combustion products leave the chamber. The spark plug must be wiped dry and calcined, and then screwed in again and started without installing the filter.
  • It is necessary to check the surface of the piston for the presence of fuel. If you unscrew the spark plug and notice through the hole that it is dry inside, you need to inject some fuel into the chamber using a syringe. The cause of problems in this case may be a blockage that interferes with the supply of fuel to the engine. If the engine can be started with a small amount of fuel, then the thrust will clear the blockage and the problem will be solved.
  • The last two actions can be performed only if the candle is dry.
  • Check the starter for serviceability. to start a chainsaw without a starter .
  • Check the ignition unit for spark.
  • Try carefully removing the tool's muffler and starting it without it.

Each saw has its own manufacturing characteristics. You can watch the video on how to start a Husqvarna chainsaw. Follow the instructions carefully and the saw will serve you for a long time.

How to start a chainsaw

The question of how to start a chainsaw can be divided into two parts:

The information from the first part will be useful to those who have lost the annotation, or to those whose annotation is not very informative.

The 2nd part will tell you what needs to be done if you have done everything according to the instructions correctly, but the chainsaw still does not start. It will also be useful for those who have trouble starting their chainsaw.

1. Start the chainsaw according to the instructions

Different chainsaws may start differently. Let's look at two more popular mechanisms that are used to start a chainsaw, available today. For example, let's take the Stihl MS 180 and Echo CS-352ES chainsaws. To properly start a Stihl, Husqvarna or other brand of chainsaw, you must first read the instructions and follow its steps. If you have a chainsaw of a different brand, then just try to start it by analogy, because most likely you have the same or a similar mechanism.

Before starting the description of the starting process, I would like to see that some chainsaws have written in the annotation that before starting the chainsaw it is necessary to turn on the critical stop brake. It's safer this way. But with a fixed brake, it is more difficult to start the chainsaw, so it is better to unlock it. If you do everything wisely, then the chainsaw will not do anything for you during startup. If you are afraid that without locking the brake, the chainsaw will cause harm to you when you try to start it, then it is better not to take up this tool at all.

So, let's start with the Stihl MS 180.

    The first thing you need to do before starting this chainsaw is to move the damper adjustment lever to the lower position (Fig. 1). Please note that this lever only moves all the way down on the chainsaw if the gas button is pressed. Therefore, we hold down the gas button and move the lever down. Then we close the valve in the carburetor and secure the gas in the pressed position on the chainsaw.

Rice. 1 After you have done this, then to start the chainsaw, you begin to vigorously pull the starter handle until you hear that the chainsaw tried to start and immediately stalled. Then we move the lever for adjusting the position of the damper on the chainsaw one step up (Fig. 2).

Rice. 2

  • In this position, we again pull the starter handle until the chainsaw starts. With all this, if you manage to start it, due to the fact that the gas handle is fixed in the pressed position, it will immediately work at high speeds.
  • Then we press and release the gas button on the chainsaw once - the throttle adjustment lever will automatically move to the working position (Fig. 3), and the speed of the chainsaw will drop.
    Now you can work. Rice. 3
  • If you need to start a heated chainsaw, then you just need to put the lever in the position as in Fig. 3, and you can start it.
  • To stop the chainsaw engine, raise the damper adjustment lever to the upper position (Fig. 4).

How to start a chainsaw: sequence of actions

It was noted that the surface on which the device is installed must be flat. But you also need to make sure that the tire is not in contact with the ground.

Startup sequence:

  • The chain brake is released.
  • To turn on the ignition, use a special button or switch.
  • The air supply damper is moved to the closed position. To fix the lever in such an intermediate form, it is pulled out.
  • The front handle is taken with the left hand and pressed down a little. The right handle has a protective shield. It should be stepped on.
  • With your free hand you pull the handle towards you. It is recommended to act smoothly. As soon as the pawls of the mechanism engage with the drum clutch, you need to make a sharp jerk.
  • When the first flash occurs, the air damper returns to its previous position. Run the tool again.

When the engine starts running, you can add gas and release the throttle lever.

Method for starting a hot engine and an engine equipped with a decompression system.

A hot engine does not need to enrich the fuel mixture with air, so start the saw without closing the air damper. Simply turn on the ignition and move the starter, after which a working chainsaw should start.

Large-volume engines have fairly severe compression, which makes cranking extremely difficult. To reduce the effort required to start a saw of large volume and power, manufacturers use special decompression valves, when pressed, the compression is noticeably reduced and the engine turns over more easily.

Valves may have different appearances, so read the instructions for the tool in advance.

Thus, before any kind of starting, be it hot or cold, it is necessary to press this valve, designed to reduce resistance, and thereby increase the service life of the starting device.

article, you can summarize the key points of starting a chainsaw. First, you need to start it with maximum safety. Second, any deviations from the launch algorithm are not allowed. And finally, you can’t start a chainsaw without a starter! Take the information from the article into account and use your tool correctly.

Preparing to start the chainsaw

Before making the first start, it is necessary to check the condition of all parts. It is prohibited to use the tool without ensuring that it is in working order. They start by preparing the fuel. Gasoline must have an octane number of at least 90. The most suitable is AI-92. Otherwise, low-quality fuel will have a negative effect on the engine. You will also need two-stroke oil. It is recommended to purchase one that is suitable for a specific chainsaw model.

The ratio of components for the mixture is prescribed in the instructions. On average, the proportions are 1:33.

Fuel may be leaded or unleaded. The first is used for tools whose engine is not equipped with a catalyst.

Then refueling is carried out. It is better to prepare the mixture in a metal container. They start by adding oil, then pour gasoline into it and bring it until smooth. The resulting composition is poured into the gas tank carefully so that the mixture does not get on the body. Close the lid tightly.

Finished fuel can be stored for a maximum of a month. Then the oxidative process begins.

It is necessary to check the chain tension. To do this, they pull it back in the middle of the tire. If the tails of the links remain in the grooves for at least 2/3 of the length, then the elements are installed correctly. The movement of the chain along the tires should not be difficult. It is also necessary to prevent excessive tension on the part. To do this, it is enough to rotate the chain manually on the bar. If there is no feeling of strong tension, rotation occurs normally, then the installation is correct.

Then proceed to install the hand brake. It is located at the front of the instrument body. The lever must be pressed forward so that after starting the chain does not start rotating. In order for the product to move, the handbrake is returned to the reverse position. Before starting the model, it is put on the brake.

It is also important to fix the product on a flat surface. This will prevent it from jerking when the engine is started.

Starter repair

The starter is responsible for starting the unit. Malfunctions indicate the presence of the following malfunctions:

Sequence of actions for replacing a worn starter cord:

The return spring is tensioned by rotating 2 turns clockwise, taking into account that it is compressed. When replacing a broken part, the spring should pop out after pulling the inner part down.

Possible startup problems

Even if all starting rules are followed, the chainsaw may not start. This occurs due to several problems. If there is no spark in the spark plug, it must either be dried or completely replaced.

When difficulties arise with supplying fuel to the filter, it is enough to blow out the fuel hose or filter. If this does not help, the parts should be replaced with new ones.

The air or fuel filter may also become clogged. High quality cleaning will be required.

If the described recommendations do not help, the tool needs a full diagnosis. Beginners should not do it. It is better to contact a service center.

The stability and reliability of its operation depends on the correct startup of the equipment. It is important to carefully check the serviceability of all parts in advance and carry out the launch correctly.

Gasoline selection

a chainsaw works best with . Most models require clean, high-quality fuel with an octane rating of no higher than 90. Sometimes online there are recommendations to mix 92 or 93 gasoline with 95 to increase its efficiency. This should not be done under any circumstances, since higher octane brands are often counterfeited, and no one will dilute the A92 or AI92 brands.

Therefore, when choosing what kind of gasoline to pour into a chainsaw in the domestic market, it is recommended to use just such fuel. It is necessary to ensure that gasoline is sufficiently fresh, since during long-term storage it begins to release resins and other elements that impair quality. Manufacturers recommend using:

How to start a Husqvarna chainsaw correctly

  • Chainsaw STIHL (STIHL) 180 - it is better to refuel with gasoline grade A90 and higher;
  • STIHL 250 - runs on gasoline with an octane rating of at least 90. Do not use fuel with ethanol content exceeding 10%;
  • Partner - you must use only unleaded gasoline with an octane rating of at least 90;
  • Husqvarna - gasoline with an octane rating of at least 90; it is possible to use pure fuel or with the addition of tetraethyl lead. Engines with a catalyst require the use of a fuel-oil mixture of unleaded gasoline.

As a rule, owners of such tools use AI92 gasoline, which fully meets the manufacturers’ requirements. However, for most domestic chainsaws A72 or A80 gasoline is quite suitable. It is also necessary to keep in mind that failure of the chainsaw due to the use of low-quality fuel is not a warranty case.

Setting up the fuel system

Factory carburetor adjustment is made according to average parameters, so the necessary adjustments to the operation of the fuel system are made during the operation of the chainsaw.

The sequence of self-tuning of the fuel system by the owner himself is given in the instructions. To bring the engine to the optimal level in terms of thrust and fuel economy, it is advisable to perform adjustments using special equipment that is equipped with service and repair services.

A running engine is checked for interruptions in the ignition system, extraneous noise, crankcase overheating and other defects. Full grinding in of loaded parts and assemblies of a new chainsaw is carried out in operating mode with moderate loads. With short breaks to cool the engine, you can cut wood with a diameter of 100-150 mm.

What fuel should I use for my chainsaw?

Choosing the right fuel is an important and significant issue. The only correct approach to solving it is to carefully study the user manual, which indicates the type and brand of fuel, the mixing proportions of gasoline and oil, and also reflects all the features of this tool. Modern standards require the use of high-octane refined fuel and special types of motor oil.

Storage conditions for the finished mixture

Most users usually prepare the fuel mixture for future use. This is explained by saving time - it is believed that it is more correct to mix a large volume once, and then simply add fuel to the instrument tank. This point of view is acceptable, but with important limitations. The finished mixture cannot be stored for too long, as irreversible changes occur in it.

Ideally, you should prepare it for only one day, but this is considered by many to be too irrational. The permissible shelf life depends on the ratio and brand of components. Most experts recommend not storing the mixture for more than 3 months. It is recommended to use metal cans and keep the mixture under cover, away from direct sunlight.

Features of the chainsaw device

A chainsaw is a chain hand tool, the cutting part of which is driven by a carburetor engine.

As a rule, this is a single-cylinder two-stroke engine.

This design is simple, economical, and can work in any position.

The structure of the saw, in addition to the engine, includes:

  • carburetor;
  • tire;
  • cutting organ (chain);
  • starter;
  • centrifugal type clutch;
  • ignition, fuel supply system, air filters;
  • chain lubrication system;
  • muffler;
  • handles.

The motor can be positioned vertically (powerful, heavy-duty professional models) or horizontally (lightweight household tools). Heavy saws are used for felling and bucking trunks and have a large frame size. Light saws are used for cutting branches or sawing firewood; they are usually owned by private home owners, farmers, gardeners, etc.

The design of the tool is simple, which guarantees high strength and reliability. The engine shaft, through the clutch, drives the drive sprocket, which moves the chain along the bar with the help of the drive sprocket. A two-stroke engine does not require a camshaft, valve system and other elements, which also helps to increase the reliability of the design.

The centrifugal clutch is equipped with two clutches, which are pressed against each other at low shaft speeds, and when the rotation speed increases, under the influence of centrifugal force, they are pressed against the outer part of the clutch and set in motion the drive sprocket. The engine power determines the type of chain - the more powerful the saw, the larger the chain pitch (the distance between the teeth, which determines the performance of the tool).

Important! Using a chain that is not compatible with the motor will result in loss of tool performance.

Gasoline to oil ratio

The standard ratio of oil to gasoline, relevant for most chainsaws, is 1 to 50. This means that for 1 liter of gasoline you need to add 20 ml of oil. However, each manufacturer has its own requirements for the composition of the fuel mixture, which are determined by the design of the engine, the characteristics of its parameters and other factors. It is impossible to determine on your own which proportions are best suited for a given instrument.

Complete and accurate information can only be obtained from the user manual. If it does not contain any instructions regarding the composition of the fuel mixture, then you should follow the generally accepted practice and make it in a ratio of 1: 50. There are other options, from 1: 20 to 1: 50.

Figure 3 – Ratios of oil and gasoline for the fuel mixture

Oil selection

A chainsaw uses two types of oil - motor oil and chain oil (adhesive oil). They should not be confused because the tasks they perform are different from each other. Any gear oil can be used to lubricate the chain, although manufacturers always recommend using materials of the same name. The requirements for motor oil are stricter. All manufacturers are unanimous on this issue - you should use oil from the same company that manufactured the saw.

Two-stroke engines do not have a lubrication system, which is replaced by the presence of some material in the fuel. The carburetor injects fuel and oil mist, which simultaneously lubricates all parts. After this, the residues are burned in the cylinder. If there are no specific instructions in the instructions, any two-stroke oil can be used.

For different tool models, manufacturers recommend:

  • for the STIHL 180 chainsaw - the best option is STIHL HP, HP SUPER or HP ULTRA oil;
  • STIHL 250 - use STIHL HP, HP SUPER or HP ULTRA oil correctly; STIHL HP ULTRA oil demonstrates the greatest efficiency;
  • Partner - any two-stroke oil. It is forbidden to use automobile or marine oil, this will lead to engine failure;
  • Husqvarna - the manufacturer recommends using Husqvarna two-stroke oil. Do not use oil for four-stroke engines or two-stroke water-cooled engines.

Important! Not all types of oil are available for sale in Russia, so sometimes you have to change them to other available types. The most successful option is the use of synthetic high-quality materials.

Criteria for choosing engine oil

A full-fledged alternative to recommended branded oils can be products from leading manufacturers with similar performance characteristics. Husqvarna brands have been leading unofficial ratings of consumer demand for many years .

  • It is strictly forbidden to use cheap analogues of unknown origin to prepare a flammable mixture for chainsaws, as well as motor oils for mopeds and boat engines.
  • In order to avoid the risks of purchasing a cheaper, but low-quality counterfeit product, it is recommended to purchase consumables from branded and licensed retail outlets.

The working mixture is prepared in a small quantity, sufficient to perform a one-time job. The flammable composition is not designed for long-term use, more than one month, due to significant deterioration in performance characteristics.

The mixture is poured through a fine-mesh filter or suede into the gas tank, from which it is supplied through a gas line to the carburetor inlet.

How to properly refuel a chainsaw to extend its service life?

The engine of a modern chainsaw is a one- or two-cylinder carburetor engine. As a rule, two-stroke models are installed, although four-stroke models are occasionally found. The rotational speed of the working shaft reaches 13.5 thousand revolutions, which puts forward strict requirements for the quality and composition of the fuel mixture.

Manufacturers inform users in sufficient detail how to refuel a chainsaw, but for many this issue remains not entirely clear. Let's take a closer look at it.

Chainsaw Husqvarna 339 xp

The household tool is suitable for cutting trees in the garden and preparing firewood for winter. It has modest parameters, but is highly stable.

  • the model has a power of 2.45 liters. With;
  • chain size – 35 cm;
  • fuel capacity – 360 ml;
  • oil container – 200 ml;
  • weight – 5 kg.

Oil does not flow to the Husqvarna chainsaw chain - reasons and solution

  • First, remove the protective cover and starter spring, after which the chainsaw air filter is dismantled.
  • Below it on the right side there is an oil pump, which needs to be inspected for cracks and other damage. If necessary, replace the pump;
  • If you notice that the oil hoses have moved away from their base, then they will also need to be replaced with new parts.

After installing new spare parts, you can continue working with the tool. In the future, use only high-quality oil from trusted manufacturers. The correctly selected sharpening angle of the Husqvarna chainsaw chain is also of great importance, since the speed of movement and the intensity of lubrication of the saw element depend on it.

Chainsaws Husqvarna 339 XP and Husqvarna 353

Both of these models are practically the same in design. The main difference is that the Husqvarna 339XP model has more modest technical parameters. The performance of chainsaws is described in detail in the table.

Both models are great for sawing logs and cutting down small to medium sized branches.

How to remove the clutch on a Husqvarna chainsaw?

  • Remove the air filter and unscrew the spark plug. If necessary, wipe the area around the chainsaw spark plug;
  • At the next stage, you will need to remove the sprocket from the Husqvarna chainsaw - this will make it possible to carefully inspect the mechanism for blockages;
  • The clutch coil is unscrewed in the clockwise direction. Under it there is a pressure washer, which also needs to be removed;
  • At the end, the sprocket is replaced and a new clutch is installed. Reassembling the Husqvarna is performed in the reverse order.

The first few starts of the chainsaw engine will be accompanied by ringing sounds - this is due to the fact that the drive sprocket will rotate until it finally falls into place.

Why won't my Husqvarna chainsaw start?

First, make sure that the tool launch algorithm is correct. Also check for fuel availability. If you do everything correctly, and there is a lot of fuel mixture in the tank, you need to look for another cause of the breakdown.

Basically, chainsaw will not start if the ignition is faulty or fuel is not supplied.

  • Check the spark plug first. If it is wet or clogged, it needs to be cleaned or replaced. The problem may lie in the coil, but replacing it with your own hands is difficult.
  • Check the fuel system. If there are breaks or cracks, they need to be repaired. You should also clean the fuel filter.

If everything was done correctly, but the saw does not work, contact a professional.
