Repair chainsaws yourself as fix the chainsaw on one's own? Video. Common chainsaw malfunctions

A chainsaw is a tool that no builders, rescuers, or simple summer residents can do without. The former need a chainsaw for the construction of structures, the manufacture of scaffolding, the latter often have to use this tool to rescue drivers who have been involved in an accident. Amateur gardeners buy chainsaws for preparing firewood for a bath, pruning overgrown tree branches. When tools do not keep a large-scale "front of work" do not simply break. Is an ordinary user like us able to find the problem on your own and not fix the chainsaw? What kind of chainsaw malfunctions, of course, fix it yourself? This article will help to give answers to all the indicated problems.

Any chainsaw, even though it is a model of a European brand (Stihl, ECHO, Husqvarna) by another domestic manufacturer (Ural, Cedar, etc.), has the same look of yours. This is a body, inside which there is an engine, not a fuel tank, on the outside there is a handle (an additional one may be present), a starter, a saw bar with a chain. With a sharp jerk of the cable, the engine starts to work, saw blade comes into action.

However, there are several situations where this does not happen. In these cases, you will begin to observe the following picture:

- the tool gets stuck in the cut;

- the saw does not start at all;

- it starts to function, but quickly stalls;

Video (click to play).

- the chainsaw does not have enough power.

You will like many reasons for this better. It is necessary to deal with all of them separately.

Join a group in contact, share experiences, ask questions.

1. If you are then faced with the fact that the chainsaw is stuck inside an impressive log, it makes no sense to panic and not try to pull it out - it can be damaged. saw bar, in addition, the entire tool will become inoperative. Turn it off, wait for the blade to come to a complete stop, and do not carefully remove the bar from the cut. To you, the reason for this situation was the blunt links of the chain. And then just replace the saw blade with a new one.

2. With a problem, our simple forgetfulness will serve. Be sure to check the presence of fuel in the tank before turning on - as this may be the reason that "the saw will not start!"

More serious problems include a faulty carburetor. To find out if it is in working order, unscrew the spark plug. If the oil is similar to dry, in other words, on the contrary, too "wet", carbon deposits are present on its surface - this indicates improper regulation of the carburetor. Set it up correctly. Remember also that the gap between the electrodes in the candle should be 0.5-0.65 mm. If this is not to such an extent, this will also cause the tool to “fail” to work.

The ignition system, too, can fail when it is diagnosed - to diagnose it, unscrew the plug, put a cover on its surface with a contact, do not pull the cable again. If there is no spark, you, the problem at this time lies in the ignition unit.

3. Remember that 2-stroke saws operate on the so-called. "Fuel mixture", not pure gasoline. If you have just such a chainsaw, observe the proportions when preparing the mixture - the correct ratio of gasoline to oil in a particular model is indicated in the instructions. Otherwise, the engine will not receive the necessary lubrication, the saw will not stall.

4. Lack of power (or work "at half strength") and possibly caused by the poor condition of the piston rings. If they hang loose enough inside the cylinder (this can be checked by slightly shaking the part), it's time to purchase spare parts.

As we can see, anyone who is in the slightest degree familiar with this tool, not the principle of its functioning, can independently establish the problem and cannot cope with its solution. However, if you do not have technical education and skills in working with a chainsaw, it is better to entrust repair professional specialists. So there is an option to protect yourself from the consequences of wrong actions, to prevent probably disastrous results, not to save money on buying a new tool.

Chainsaws, simple in design and reliable in operation, are very popular among owners of private houses and summer residents. With the right handling of this tool, it takes a long time and rarely breaks. Moreover, it will not be difficult to eliminate the cause of the chainsaw malfunction with your own hands, especially if you know where to look for the cause.

The Swedish manufacturer's tool can turn hard work into a simple task. Chainsaw models "Husqvarna 137", "Husqvarna 240" and "Husqvarna 365" features three features:

high engine power;
improved engine filtration system;
the ability to absorb unnecessary vibrations.

If the tool is operated strictly according to the instructions and its malfunctions are eliminated in a timely manner, then it will delight with reliable and stable operation. Correctly carried out repairs with original spare parts will allow you to use the saw for a long time.

The main cause of chainsaw breakdown is most often engine failures, which can manifest as follows:

do not start;
work unstable at idle;
start up and immediately stall;
not have enough power.

In this case, the malfunction should be sought in the ignition system, piston group or fuel system. Often the reason for poor performance of the tool can be associated with the clutch, brake system, lubrication mechanisms, tire.

Do-it-yourself repair of the Husqvarna 240 chainsaw, and of any other model, should begin with troubleshooting the ignition system.

First of all, experts recommend get and inspect a candle... The state of this element will indicate deficiencies in the operation of the fuel system.

If the plug is completely dry, it means that the fuel mixture does not enter the cylinder. In this case, the plug is screwed into place and the fuel system is repaired.
If the spark plug is heavily flooded with a fuel mixture, then the rules for starting the unit may be violated, or the carburetor is poorly adjusted. Shut off the fuel supply and start the starter. This is done in order to remove excess fuel. The candle must first be cleaned with a sharp object, then rinsed with detergents, dried with a hairdryer and reinstalled. After that, the tool is launched and its work is checked.
If there are no fuel residues on the spark plug, then it must be cleaned, washed and checked for a spark. Its absence may indicate a violation of the gap between the flywheel and its magnetic circuit or a breakdown of the ignition module.

A malfunction in the ignition system can be associated with the use of poor oil or with an incorrect ratio of gasoline and oil.

If the fuel does not flow into the tank of the chainsaw, then this may be two reasons:

The filter is clogged.
Lid clogged.

In this case, the fuel is not supplied in full, and the tool does not start or starts and immediately stalls. The repair consists of cleaning the air filter and cover.

The filter must be removed very carefully so that dirt that clogs it does not get into the carburetor. It is cleaned and washed with ordinary detergents.

The heart of any chainsaw is the carburetor, with which most tool breakdowns are associated.

Do-it-yourself repair of this unit consists of disassembly and cleaning.If the breakdown is serious, then contact the service center for help.

Most often, tool malfunctions are associated with the use of gasoline or poor quality oil... To protect the carburetor from damage, you must follow some preventive measures:

Start the chainsaw strictly according to the instructions.
It is not recommended to store gasoline in a plastic container. This will help to avoid heavy carbon deposits.
The fuel mixture cannot be stored for a long time, as it loses its quality over time.

This brand is very popular among both individuals and professionals. This easy-to-use and reliable tool can last a long time without being repaired. There are situations when the "Calm" chainsaw does not start or stalls right after the plant. You can find out what to do in these cases by watching the video instruction.

The reasons should be sought sequentially, moving from simple to complex. You should not immediately disassemble the carburetor, which is equipped with many different parts and small elements.

First of all, it is necessary check fuel availability and pay attention to its preparation. The mixture should consist of high quality gasoline and oil, the brand of which is indicated in the instructions attached to the saw.

The saw may not start due to the fact that at the moment of starting the spark plug is filled with gasoline. The problem is corrected by drying out or replacing the spark plug and draining the excess fuel.

Quite often, if there is poor contact between the tip of the candle and the high-voltage wire attached to it, there may be no spark. In this case, the connection should be restored. If after this the spark does not appear, then the electronic ignition unit is most likely faulty. It must be replaced with a new one.

You cannot count on an easy start and operation of the chainsaw if its filter is clogged. It needs to be taken out, well cleaned and rinsed, paying particular attention to the mesh.

Sometimes the saw motor will not start due to a malfunction of the cylinder-piston group... In this case, for repair you will need:

Unscrew the bolts and remove the cylinder from the block.
Check the integrity of the piston and cylinder.
If the cylinder is damaged, then it must be replaced with a new one, or it must be repaired by boring the mirror to the size of the piston.
Determine the degree of wear of the piston rings and replace if necessary.

For an instrument that ran on relatively normal fuel, such procedures are sufficient. Now you can saw reassemble.

Some parts of the "Husqvarna" and "Calm" chainsaws must be replaced after the expiry of the passport service life. These terms are spelled out in the instructions attached to the tool. It also indicates how to properly wind the instrument. Acting according to the instructions, distinguishing between cold and hot starts and using the chainsaw strictly for its intended purpose, it will be necessary to repair it very rarely.

Today, almost every owner of a private house or an advanced summer resident uses a chainsaw, which is highly mobile, unpretentious in operation and repair. Among the many models of gasoline vehicles and equipment on the market, the Swedish brand Husqvarna is worth highlighting. Founded 400 years ago, the Husqvarna company first produced weapons, and in 1959, in connection with the need to expand the line of products, launched the production of chainsaws. Unlike competitors, this manufacturer sought to improve the layout of the saw. To reduce the level of noise emitted by the engine, the famous designer from Sweden Sixten Sazon used a muffler in the Husqvarna chainsaw using the example of a motorcycle.Almost all professional and amateur chainsaws are equipped with air-cooled two-stroke gasoline engines.

Chainsaw Husqvarna: main components

This assumes the presence of at least one cylinder with heat sink fins. The fuel supply system (carburetor) acts as a gasoline-air mixer.Dirt, dust, shavings should not enter the working combustion chamber together with the fuel mixture, and filters are installed on the saws to clean the supplied air. Manufacturers recommend changing the filter once a season. In the interval between replacements with a frequency of once for 10-15 fillings, it must be cleaned.

For convenience and ease of starting the internal combustion engine in any chainsaw, a starter is provided, which is a reel with a wound cable and a handle. Even the most powerful husqvarna chainsaw is equipped with an intelligent starting mechanism.

In order to reduce the vibration transmitted to the hands of the feller, a special device is installed on the tool. In addition, this mechanism prevents the tire from "pulling" when cutting wood.

Despite the fact that ideal chainsaws have not been created and it is unlikely that anyone will succeed, this Swedish company strives for design perfection and increasing the power of its models. The entire husqvarna range of saws are characterized by pleasant enhancements that make their owner's job much easier.

General view of husqvarna chainsaw

These positive options include:

use of the fuel "suction" button (primer) for the convenience of starting the internal combustion engine;
automatic adjustment of the carburetor by the Auto Tune system;
side chain tensioning mechanism;
environmentally friendly and powerful X-Torg engine;
vibration reduction system;
a mechanism for forced lubrication of the chain through a hole in the driven sprocket;
centrifugal air purification Air Injection, which makes it possible to change the filter less often;
universal key for service and repair.

In order to avoid the acquisition of fake Husqvarna chainsaws, it must be remembered that their licensed production is established exclusively in Sweden, USA, Russia, Brazil.

Regardless of the power, performance and size of the models, their problems are divided into 2 types:

Malfunctions of the engine, fuel supply system, cylinder-piston group, muffler;
Transmission breakdowns (malfunctions of the brake system, tire, chain, clutch, etc.).

Based on many years of experience, most experts say with confidence that mainly the causes of breakdowns lie in the operation of the internal combustion engine. The striking manifestations of the incorrect operation of the chainsaw motor include:

difficult start;
unstable idling;
does not develop full power;
extraneous sounds are heard during operation.

In order to reduce the complexity of diagnostics and subsequent repair of the Husqvarna chainsaw with their own hands, experts advise starting with simpler units and parts for maintainability.

The first step in ignition diagnostics is to check the spark plug. It must be unscrewed from the cylinder shaft with a special wrench or socket head. The gap between the side and center electrodes should vary from 0.7 to 1.5 mm.

Husqvarna chainsaw malfunctions

If this distance is exceeded, there will be a periodic absence of a spark. On the contrary, if the gap is too small, the discharge will not be sufficient for full ignition of the fuel mixture. You can set the recommended gap parameters using locksmith probes, which you can buy at any car store.

If there are traces of gasoline on the surface of the candle, then most likely it does not completely burn out. It is not necessary to look for the causes of malfunctions in the Husqvarna ignition system in the absence of moisture on the plug, since in this case it is necessary to adjust the fuel system, the steps of which are described below.

The most common types of ignition failures include improper clearance (more or less 0.2 mm) between the flywheel and the ignition coil. It can also be set independently by means of the probes.

The fuel supply system is one of the most difficult in the unit, and therefore it is worth taking it as seriously as possible and following certain rules. Gasoline may not flow to the carburetor for the following reasons:

- clogged breather (holes in the tank lid);

- the fuel filter is clogged with dirt.

To clean the breather, you need to prepare a regular sewing needle. In the second case, it will be necessary to dismantle the tank and replace the fuel filter.

Carburetor with adjusting screws

The entire range of the Swedish manufacturer is equipped with traditional carburetors with three adjustment screws:

Screw "T" - setting the mixture supply at idle;
Screw "L" - low speed adjustment;
Screw "H" - at maximum speed.

First of all, it is necessary to "find" the highest speed with the screw L in the absence of load (at idle speed). Then turn it counterclockwise by a quarter of a turn.

If, in this position, the chain on the bar continues to move, you need to achieve a stop by means of screw T.

Husqvarna chainsaw carburetor

To adjust the Husqvarna carburetor at maximum speed, after pressing the accelerator key for full, wait 10-15 seconds. Turn the screw "H" clockwise ¼ turn and listen to the operation of the internal combustion engine. If during engine operation there is an extraneous ringing "squeal", gradually unscrew the bolt until it disappears. On the contrary, in case of excessive smoke production, it is required to lean the mixture, gradually tightening the screw.

After setting the minimum and maximum revolutions, we adjust the saw idle. To do this, turn the screw "T" clockwise until the chain starts moving along the bus.

Correct tuning of the fuel delivery system requires a tachometer (a device for measuring revolutions per minute), as well as the experience of the owner.

The ICE starting system is used to turn the shaft and, as a result, the appearance of a spark and ignition of the fuel mixture. Like most models, Husqvarna's kick starter consists of:

Chainsaw starter Husqvarna

When the starter jerks, the drum ratchet engages with the engine shaft, as a result of which the crankshaft will rotate. Despite the condition of the tool, starting the engine the first time is quite problematic. To facilitate the start, it is required to make several presses of the primer (the button for pumping the mixture). A backup spring can be provided in the design of the starter, which, after being compressed by the main one, gives a sharp push to the shaft. As such, the repair of the starter is not provided, and if one of the elements breaks down, it will need to be replaced.

The cutting saw chain of this manufacturer consists of working teeth, depth stops, locking pins. The most loaded in the sawing process are the cutting links made of high-alloy structural steel. By design, they are divided into left and right-handed. The cutting width is determined by the distance from the side edges of the left and right links.

DIY husqvarna chain tensioning

The main characteristic of the husqvarna chainsaw chain is the pitch, which can be measured from the first to the third rivet by dividing the result by two. Due to the fact that the inch is adopted in the Western system of calculation, manufacturers in their passports indicate the step in inches (25.4 mm) with the instrument. Medium chainsaws use 3/8 '' chains, and heavier weighted chains use 4.

One of the most important indicators of the chain is the thickness of the shank, which for most models is 1.3 mm. They are often used on specialized and general amateur instruments. The thickness of the links must be matched to the groove in the bar, as excessive thickness can lead to chain breakage or fall.

When the chain is relaxed, it must be tightened by means of the mechanism located on the side of the unit. Having previously removed the left side cover (2 bolts), weaken the tire for the husqvarna chainsaw. Next, we unscrew the longitudinally tightened bolt, thereby moving the guide away from the power unit. When properly adjusted, the chain should roll easily but not dangle on the bar.

An important protective unit in a chainsaw is certainly the chain brake, which, in the event of a kickback, blocks the rotation of the cutting edges. As a result of the tire rebound in the direction of the feller and, as a consequence, his possible injury, the friction mechanism disengages the drive sprocket and the drive shaft.

Husqvarna Chainsaw Chain Bar Slip

The brake start can be of contact or inertia design. In the first case, the protection will be triggered as a result of the return throw of the unit. The inertial brake system is the generation of large inertial forces acting on the drive shaft. Regardless of the features of a particular design, experts recommend purchasing chainsaws equipped with similar mechanisms.

After the repair and adjustment of the Husqvarna chainsaw, it is required first of all to check the performance of the brake assembly.

In all models of chainsaws presented, oil is supplied to the tire automatically.

The main components of the husqvarna chain lubrication system

Before starting work, you need to make sure that there is a lubricant in the reservoir. The oil pump interacts with the drive sprocket, and as the shaft rotates, the gear delivers lubricant to the running surface of the chain. Due to the constant presence of oil on the cutting edges, the chain is less prone to friction and, as a result, loses its properties noticeably more slowly. If the lubrication mechanism fails, the husqvarna saw will have a fine brown chain. Periodically, the left protective cover of the unit must be removed and the oil hole cleaned with compressed air or a needle. The delivery rate of the pumping unit directly depends on the number of revolutions of the tool.

Adjustment of the carburetor Husqvarna three hundred seventy two XP, 365

Adjusting the carburetor of a Husqvarna 372 XP chainsaw means adjusting the engine to suit local conditions, nettle climate, altitude, gasoline quality, not the type of oil for 2-stroke engines.

The carburetor is equipped with three adjustment options:

L = Low speed jet.
H = High speed jet.
T = Screw for adjusting idle speed.

Jets L not H regulate the amount of fuel to match the air flow supplied by the throttle valve.

If the jets are screwed in clockwise, the mixture will be lean (less fuel in relation to the amount of air), not when unscrewing the jets counterclockwise, the mixture will be richer.

A lean mixture gives higher revs and a richer mixture. lower revs. The T screw adjusts the position of the throttle at idle.

If the screw T is turned clockwise, the number of idle turns will increase when the screw is turned counter-clockwise arrows then number of revolutions will go down.

Pre-adjustment and running-in of a Husqvarna chainsaw three hundred and sixty-five XP

When checking the operation at the factory, a preliminary adjustment of the carburetor was carried out. Pre-adjustment: H = one revolution, respectively L = one revolution.

To saw engine parts Husqvarna received sufficient lubrication (running in) the carburetor was set to slightly increased enrichment of the fuel mixture for the first 3-4 hours of operation.

For this setup, most RPMs are set at 6-700 RPM below recommended.

If it is not possible to check most of the revolutions with a tachometer, then the H jet does not have to be set to a fuel mixture below the presetting.

The maximum number of revolutions must not be exceeded. Adjusting the carburetor, you can repair the calm 365 chainsaw with your own hands - video. Do-it-yourself chainsaw repair and reasons. If the chain of the chainsaw rotates at idle, then by turning the screw T counter-clockwise arrows need to achieve its working option to stop.

Precise adjustment of the carburetor of the Husqvarna 365 chainsaw, three hundred seventy two HR

After a Husqvarna chain saw has been running in three hundred and seventy-two XP, it is necessary to fine-tune the carburetor.

First you need to adjust the jet L, then the idle screw T, not after a while, the jet H. The following most of the revolutions are recommended: 12500, at idle speed seven hundred rpm.

At the time of adjustment, the air filter must be clean, not the cylinder cover is installed in the area.

When adjusting the carburetor with a dirty air filter, the fuel mixture will be too lean when the air filter is cleaned differently the next time.
A too lean mixture will damage the engine.

Carefully screw in the L jets, not H, to the bottom, and then unscrew them one turn. Do-it-yourself electric saw repair is of interest to all owners of such tools. Do-it-yourself Husqvarna chainsaw repair. Husqvarna saw models installed. The carburetor is now set to H = 1 not L = 1.

The chainsaw is an indispensable assistant for every real owner.

Since the inception of the instrument, its popularity has grown rapidly.

So, the Husqvarna 142 chainsaw has high functionality. It is widely used not only in forestry, but also in personal plots.

Choosing a chainsaw is pretty easy. So, it is best to pay attention to well-known brands such as Husqvarna. This company produces a wide range of such tools. Husqvarna 240 and other models are of high quality and functionality. But, unfortunately, even such tools are not insured against breakdowns.

After the chainsaw appeared in the house, many owners breathed a sigh of relief.

After all, this tool allows you to solve complex problems quite quickly and easily.

But, here it is worth considering that the chainsaw often fails. This is due to the fact that it is subjected to heavy loads during operation. Therefore, you must always be ready to eliminate breakdowns.

Today there are a large number of workshops that offer their services for the repair of chainsaws and other tools. But, this does not mean that if a malfunction occurs, you must immediately run to the repair shop.

Some faults can be corrected by hand. To do this, you just need to know the main causes of breakdowns and how to eliminate them.

So, in the process of frequent use of the tool, breakdowns may occur:

carburetor;
muffler;
oil pump;
ignition and fuel supply systems.

Each of these breakdowns can be repaired with your own hands. The main thing is to know the sequence of work when eliminating a particular malfunction.

Read the article on self-repair of the Stihl 180 chainsaw here.

If the tool suddenly stops working, then the first thing to check is the ignition system. And you need to start with a candle.

You need to do the work very carefully. For this, a special hook is used. First you need to disconnect the wire and remove the candle.

If it is dry, it means that no fuel is entering the cylinder.

If there is spray on it, then the breakdown may lie in the carburetor or in the start rule. To fix the breakdown, you need to wipe the spark plug and shut off the fuel supply. The starter is then started.

Thus, the combustion chamber is ventilated and excess fuel is removed.After that, the candle is installed in place and the chainsaw starts up.

If there is carbon deposits on the candles, then this indicates that the Husqvarna 137 chainsaw is running on low-quality fuel. Carbon deposits are also formed as a result of an incorrect fuel to oil ratio. In order for the tool to work as long as possible, you need to carefully study the instruction manual.

If there is carbon deposits on the candle, then it must be carefully removed. You can use an awl for this. The electrodes are gently rubbed with a sandpaper. After that, it is installed in place. You also need to fill in the fuel that is recommended for this model of the chainsaw.

Read the article about repairing a chainsaw Partner 350 with your own hands here.

If the tool does not work, then this may be due to the fact that no fuel enters the cylinder.

First of all, you need to check the fuel filter for contamination. To check this, you need to remove the fuel hose and check how fast the fuel flows.

If it is supplied under low pressure, then the problem lies precisely in the filter.

In this case, the filter must be cleaned. It goes directly through the tank. The filter is cleaned and installed back. It is washed under running clean water.

After that, the filter is dried and carefully put back. To prevent such a problem in the future, it is necessary to periodically clean the filter.

If cleaning the filter did not give a positive result, then you should pay attention to the breather. A clogged hole will result in insufficient air flow into the carburetor.

With frequent use of the chainsaw, muffler malfunctions may occur. It is very simple to define it.

If the tool is working properly, and when the speed increases, it starts to stall, then the reason lies in the spark arrester.

Most often, the breakdown of this element is due to clogging with combustion waste. You can easily solve this problem with your own hands.

First of all, you need to remove the muffler and disassemble it. It is worth considering here that spark arresters are not understandable in some models. After that, the muffler is cleaned of carbon deposits. For this, use special detergents.

When the carbon deposits have been removed, the spark arrestor is dried with a hair dryer. At the final stage, the muffler is installed in place.

As for the carburetor, it can be adjusted and repaired at home. But in order to perform such work efficiently, you need to know the structure of the carburetor and the principle of its repair.

Poor repairs can cause serious damage to the device. Therefore, experts recommend that you carry out its adjustment and repair in special workshops.

As you can see, it is fashionable to eliminate many of the malfunctions of the chainsaw with your own hands. But to do this, you need to have certain information. If you are not confident in your abilities, then it is better to seek help from specialists.

The chainsaw has become an indispensable and important tool in the daily life of every owner. The popularity of this tool has grown from the very beginning of its inception, since with its functionality, to a large extent, it made the life of every forester, gardener and simply ...How to choose a chainsaw is not an easy question, the range of products is simply huge, so many people have difficulties when buying this product. After all, you want not only to buy a chainsaw for yourself, but also to profitably invest your money, and buy a really reliable and practical thing. If you decide to acquire this kind of equipment, and do not know what to look for in the first place when buying, then this article is for you.Here you can find answers to your questions regarding the technical characteristics of one of the most popular models among chainsaws - Husqvarna 137. This "amateur" version of the chainsaw, more professional is the shtil chainsaw.Husqvarna is a company that has been making high quality garden tools and equipment for many years, and its products are perfect for industrial large-scale construction.The range of the manufacturer is huge, but the main focus of the company is the production of chainsaws.In creating their "masterpieces", the manufacturer primarily strives for quality, and also pays great attention to innovations related to the production of this kind of technology.It is this feature that inspires great confidence among buyers.Such a model has a significant advantage, namely, low weight, which contributes to more convenient operation, and it is also quite economical, since the manufacturer has equipped it with a (two-stroke) engine that has a small volume. But despite this kind of functionality, the Husqvarna chainsaw is powerful enough. One of the most successful models is the Husqvarna 137 saw.As for the characteristics of the chainsaw, then its weight is about 4.6 kilograms, despite the fact that this is the "clean" weight of the tool, without the presence of oil, fuel and tires with a chain.

If you are faced with a malfunction of the chainsaw, then the first thing to do is check the spark plug.But this must be done very carefully, by first disconnecting the wire by means of a special hook. The most important thing that you should pay attention to is the direct appearance of the candle.A dry surface indicates that fuel has stopped flowing into the cylinder, therefore, the problem is not with the spark plug, so it must be screwed back.But if spark plug covered with fuel splashes, then this indicates that the problem is either in the carburetor, the adjustment of which was not made correctly, or the start rule has been violated.

In order to eliminate this kind of problem, it is necessary to thoroughly wipe the spark plug, turn off the fuel supply and turn on the starter. This is done in order to ventilate the combustion chamber and get rid of excess fuel. After that, the cleaned candle must be installed in place and the chainsaw must be started.

And the last thing that can happen to a candle is that it can be covered with carbon, which indicates that you are using poor quality oil, which is not acceptable if you want the tool to serve you for many years. Also, the reason for this may be an error in the calculation of oil and gasoline, and the incorrect process of adjusting the carburetor.

In this case, you must clean the candle by rinsing it and removing carbon deposits with an awl, then wipe the electrodes with a sandpaper and reinstall. In addition, it is important that the gap directly between the electrodes and the spark plug should not exceed 0.5 - 0.65 mm, otherwise a new gasket must be installed.

It is important to pay attention to whether a spark is present. For this kind of manipulation, you need to put the ignition cable directly on the spark plug, then connect the cylinder and the nut on the spark plug with pliers and start the starter.

After which sparks should appear, but if they are missing, then in this case there is a problem with the malfunction of the chainsaw in the spark plug, which must be replaced. But there are times when there is no spark even after replacement, this indicates that the high-voltage wire is faulty or the direct connection with the candle is broken.

There are situations when fuel does not enter the cylinder, this kind of malfunction can occur for the following reasons: firstly, a dirty filter (fuel). In order to clean it, you must first remove the hose (fuel), and then check how well the fuel flows. Since through this manipulation you can find out what is the cause of the breakdown.

Since if the jet is weak, then the reason is in the filter, that is, it needs to be cleaned. To do this, it must be obtained directly through the tank, namely through its fuel hole. Naturally, you can reduce the likelihood of contamination, but for this you need to carry out periodic preventive maintenance, namely, it is advisable to replace the old filter with a new one at least once every three months. Insufficient viscosity of the oil for the chainsaw chain can also cause a breakdown.

It can also take place in breakage clogging of a special hole, which is located on the fuel tank, namely on the lid. This kind of hole is called a breather. You can check whether it is working properly or not by disconnecting the hose, and then cleaning it with a needle. It is also worth noting that there are several reasons for the breakdown, one of which is contamination of the filter (air).

Consequently, the air does not enter the required amount directly into the carburetor, this leads to the fact that the process of motor work is disrupted. If you encounter a problem when the chainsaw stalls when you add gas, see the details here.

In order to clean the filter, it is necessary to rinse and clean it in clean water, but this must be done very carefully. After that, it is very important to dry it and install it in place.And also the cause of the breakdown may be incorrect adjustment of the carburetor, which must be done with three screws.

But remember that every manipulation must be carried out, using the instructions, since otherwise you can only aggravate the situation.

And the final cause of the breakdown is considered clogged channels or the integrity of the carburetor membrane is broken.

If your chainsaw starts and stalls, the reason for the video is here.

If you are faced with a situation where the engine works great directly at low speeds, and if the speed increases, it starts to stall, then the spark arrester is faulty.

The spark arrester in the muffler is most likely clogged with combustion debris.

In order to clean it, you must first remove the muffler, and then disassemble. It is worth remembering that there are also models that cannot be disassembled. After you got the muffler out of it need to be cleaned of carbon deposits, by means of detergents, after washing, be sure to dry it with a hairdryer, and after the manipulations are finally completed, you must install it in place.
