The chainsaw has long been not a luxury, but a necessary tool for those who have country cottage area or home ownership. But, like any other technique, this tool tends to fail, despite the simple device.
The classification of the main faults includes:
- complete lack of engine plant
- engine starts and stops
- unstable operation of the tool
- stop work under load
- power loss.
If the chainsaw does not start at all, the reason may be as follows:
- Manufacturing defect
- Lack of fuel
- Problems with starting the ignition system
- No spark from spark plugs
- Poor quality fuel mixture
- Clogged carburetor
- Problems with high voltage wire
- Lack of compression.
Why does the chainsaw start and stall, what to do in this case? The reasons for this need to be considered in detail.
The reason that the chainsaw may stall immediately after the plant lies in the malfunction of a certain piece of equipment.
- The most banal reason why the chainsaw started up and stalled may be the low level of fuel in the tank. This can be confirmed by stopping the tool when tilted, when fuel residues accumulate in a certain place in the fuel tank. With low-quality fuel, there may also be a problem with the operation of the chainsaw, in which case it is necessary to completely replace it.
- Clogged breather, which significantly reduces fuel consumption to the engine.
- Insufficient contact of the wire cap with the spark plug, which leads to strong heating of the spark plug insulator. Contact deterioration may occur due to mechanical shear or carbon deposits.
- Broken spark plugs.
- Clogged muffler, due to which the output of exhaust gases deteriorates, leading to a stoppage of the engine. For this reason, the chainsaw can start and stall at idle. Muffler sediment can also appear due to low-quality fuel or not correct operation tool.
- Poor carburetor adjustment.
- Piston group failure
- Problems with the fuel filter or pump. In this case, gasoline may flow through the pump or poorly flow through the fuel filter to the carburetor. As a result, the chainsaw starts and stalls with increasing speed.
- Air filter dirty. Problems with this piece of equipment lead to the fact that, with increased loads on the engine, it simply cannot cope with them due to blockage and stops. A similar result is also obtained with an increase in speed.
- Chain shorting due to lack of or insufficient lubrication, as well as a malfunction with the chain brake.
Why does a chainsaw start badly and stall
If the equipment is not started “on a cold” the problem may be in the absence of compression, i.e. the rings are worn out due to a long service life, they need to be replaced. Sometimes the reason that the engine does not start well when not warmed up is a problem with the muffler, as well as poor contact between the spark plug and the wire.
Also, the reasons for a poor start may be wear or damage to the gasket, rubber cuff in the carburetor accelerator pump, which causes additional air flow, leading to an increase in saw speed.
Troubleshooting
The operation of the equipment must be correct, with periodic inspection of the constituent elements to prevent breakage. To troubleshoot, it is necessary to check all components of the equipment for their functioning.
If the chainsaw starts and stalls, the cause can be eliminated on its own. If it is a lack or improperly prepared fuel mixture, this must be corrected. For prevention, when the chainsaw is idle, always drain the remaining fuel.
Spark plugs should be checked periodically. In this case, carbon deposits clogging the connection gap should be removed, and the tips should also be checked for fuel. Another cause of problems with spark plugs can be soaked with gasoline. To do this, they need to be removed, wiped with a rag and left to dry. Faulty spark plugs are replaced.
If there is no spark between the spark plug and the high voltage wire, but if there is a good connection between them, the ignition unit must be replaced.
A clogged muffler is a common cause of a breakdown in which the chainsaw starts and immediately stalls. To eliminate the malfunction, you need to dismantle the muffler, clean it from soot with sandpaper or a special chemical solution. If the chainsaw model is non-separable, the system is filled with chemical substances and stay there for several hours, then it is blown.
The carburetor needs to be adjusted if the chainsaw stalls at idle. Fine tuning is a rather laborious process, so it is usually done in service centers. But, on some models there are elements for setting it up, just turn the bolt half a turn to increase the speed of the chainsaw, the problems will be fixed. If the jets, nozzles, channels and filters are clogged, it is necessary to disassemble and clean the entire carburetor. When the seals, gaskets, cuffs are worn, they must be replaced, preventing the "leakage" of air.
If there is a problem with the fuel or air filter, the fuel pump must be replaced or the air filter cleaned.
If the breather is clogged, it is necessary to clean it with a regular needle.
When the chainsaw starts and immediately stalls, the reason may lie in the incorrect operation of the chain. To eliminate problems, the presence of oil in the chain lubrication reservoir is checked, as well as the oil drain tube for breaks or blockages.
When inspecting the piston group, you should pay attention to the cylinder, if necessary, replace it or the piston. You can bore the cylinder to fit the new piston. If the piston with the cylinder is normal, you should pay attention to the defects of the piston rings and the need to replace them.
Among other things, it is necessary to control the service life of the parts indicated in the product passport, which include the drive sprocket, tire, chain, part of the anti-vibration system, and replace them in time.
With a long idle time of the tool, it is worth checking the condition of the fuel line. If the tube is cracked, you will have to replace it with a new one.
Why is the chainsaw deaf under load
Running chainsaws and stalls, cause
A chainsaw is no longer a luxury, but a necessary tool for those who have at least some kind of suburban area. With it, you can do gardening, collect firewood, recycle lumber, and more. On sale there are a lot of models of chainsaws, differing both in performance and overall quality of workmanship. You can check it out here. e-catalog.ru.
However, any method can be quirky, and chainsaws are no exception. Let's consider the most typical problems.
Tool stops straightaway after the start
Chainsaws with increased speed
The reasons for this are similar to the previous ones: either a problem in the fuel system or in the air filter. Try to disconnect the fuel hose from the carburetor. if gasoline is leaking badly (but you know for sure that there is fuel in the tank), the problem is in the gasoline filter. At the same time, you can also check the fuel pump. fuel must not flow through it. If this happens, the pump should be replaced.
Why the chainsaw is dying
There are several reasons why a chainsaw is deaf. And, as a rule, almost all of them are solved on their own, without going to the service center.
Check filters: fuel and air. If they are clogged, then, of course, this is the cause of the tool not working properly. And dirt is not always visible to the naked eye. Therefore, even if everything seems to be in order, it is better to carry out this procedure.
The second reason, perhaps, is the candle. Remember when you last changed it? According to chainsaw operating rules, this should be done once a year.
If this does not help, then it is worth trying to adjust the carburetor. Probably due to vibrations when working with a chainsaw, its factory settings were lost.
If the saw stops after a long period of storage, such as in an unheated garage, then it is worth looking at the fuel line. This is usually a rubber tube, which can become cracked and damp from humidity and temperature drops and cause the chainsaw to malfunction.
If none of the above helped, then most likely the breakdown is more serious and, unfortunately, you will have to contact the workshop.
What if the chainsaw is dead?
- Non-standard carburettor work
- Fuel System Problems
- Problems idling due to muffler failure
- Malfunctions of the cylinder-piston group
Builders, installers, rescuers and gardeners # 8211 all of them, sooner or later, perform their tasks, take a chainsaw. And how reliably this tool will work, the final result of their activities largely depends.
A chainsaw is used to cut wood.
It should be noted that the chainsaw is a relatively simple device. However, like other mechanisms, it periodically breaks down. When the chainsaw goes out at idle (this is one of the most common faults), the biggest problem is to determine the reasons for this behavior of the device. If the source of the "disease" is correctly identified, it will not be too difficult to return the device to its working position.

Therefore, the first thing to do is to find out what faults the chainsaw has and what causes the engine to stop at idle.
The car stops idling: possible causes
To answer the question of why the saw, periodically whimsical, stops at idle, it should be borne in mind that this tool is based on a conventional two-stroke internal combustion engine.
From this it follows that various problems with the main components of any ICE lead to failures: fuel and lubricants, the ignition system, the quality of the air-fuel mixture and compression inside the cylinder.
The main engine malfunctions are as follows:
- engine does not start
- It starts, but, working uncertainly, quickly stops at Idling
- The chainsaw runs fine at idle, but stops under load.
The causes of idling disorders can be different. But they can all be reduced to a few general positions. Thus, problems such as:

Problems with fuel and air filters and their elimination
The chainsaw will stall at idle if the fuel or air filter becomes clogged. To find out the condition of the first element of the fuel system, it is necessary to disconnect the gasoline line from the carburetor. If the fuel is supplied in the form of doses that meet the specified standards, the cause of the malfunction should be sought elsewhere. If gasoline enters the carburetor lightly or does not flow out of the hose, the filter is most likely clogged with debris.
To clean, remove it from the tank (from the tank until this point is completely discharged). Extraction is carried out through the filler neck of the tank using a wire hook. The filter is disconnected from the suction hose. If possible, the filter is cleaned. If this is not possible or there is no practical solution for a number of reasons, the used filter is changed to a new one.
The chainsaw may stall if the fuel filter becomes clogged.
The air filter can also become clogged with dirt or dust, resulting in poor idling. It should be remembered that clogging of this filter occurs quite often, as a result of which the air flow into the system is difficult. In the fuel-air mixture, the proportion of gasoline increases, and it turns out to be excessively enriched. In this case, normal engine operation cannot be expected.
For cleaning, the air filter is removed with extreme care so as not to vacuum the carburetor. Then it is cleaned and washed thoroughly. Detergent is added to the wash water. After drying, the air filter returns to its place in the chainsaw.
For proper operation of the cutting tool, it is recommended to change the fuel and air filters every 3 months.

Spark plug problems and how to fix them
It is generally recommended that this key component of the ignition system be changed at least once a year. But often the owners of saws forget about this rule. And therefore, do not be surprised that a device that is serviced in a fragmented manner, as a result, does not hold idle time well.
The spark plug of a chainsaw should be changed once a year.
Therefore, it is necessary to pay attention to the following errors associated with the operation of this system:
- Filling the spark plug with gasoline at the time of starting. To fix the problem, they get a candle and dry it without calcining it. Excess fuel flows out of the engine through the hole into which the spark plug is screwed. After a break of 30 minutes, the candle is inserted into place, the mechanism starts.
- Lack of spark due to poor contact between the tip of the spark plug and the high voltage wire. The connection is checked, if the defect is broken, the defect is eliminated.
- No spark due to faulty ignition electronics. If there is confidence in the reliability of the connection of the tip to the high-voltage wire, but there are still no sparks with the starter turned on, a malfunction of the ignition unit may be the cause of the failure. This component is not restored, it is only changed to a new one.
- Incorrect gap between spark plug electrodes. IN different types candles, this figure is from 0.2 to 0.5 mm. The correct gap is set using a suitable pressure gauge. More or less clearance for this type of candle is not allowed.
Meanwhile, during the initial inspection of the candle, you can find out that the reason for the failure of the chainsaw from defects in the spark plug or other elements of the ignition system is not at all.
Spark plugs can tell you if the saw is malfunctioning.
So, if the spark plug is completely dry, it may mean that the initial problem is the impossibility of getting fuel into the combustion chamber. In this case, you must check the entire gasoline supply chain from the carburetor itself. Filters on CHAINSAW!!! Author: Look Tool Published: 23 Dec.

Disassemble and assemble the carburetor need without haste as it has many parts without which it cannot work.
Often, erratic operation results in misalignment of this device, which is responsible for supplying a certain amount of air-fuel mixture to the engine cylinder. Adjust it with three special screws located on the carburetor: the maximum and minimum speed screws, as well as the screw that controls the idle speed.
Some manufacturers, fearing unwanted interference from incompetent people, supply their products with only one screw during an unoccupied year. But in both cases, the adjustment of the carburetor can only be carried out if exactly all the manufacturer's instructions are followed.
However, even after adjusting the carburetor, in accordance with the factory rules, this unit may jam. Then it is recommended to clean the fuel and air channels, jets, filter element mesh. If the membrane is damaged, it must be replaced with a new and high quality one.
Taking care of maintenance and, we must always remember that it is usually stuffed with a lot of small parts, without which the device simply cannot work properly. Therefore, disassembly and assembly of the carburetor should be done slowly and with extreme caution.
Why does the chainsaw stall under load
Chainsaw starts and stalls, the reason
A chainsaw has long been not a luxury, but a necessary tool for anyone who has at least some suburban area. With its help, you can perform garden work, harvesting firewood, finalizing lumber and much more. On sale there are a lot of models of chainsaws, differing both in power and in overall quality of performance. You can verify this here. e-catalog.ru.
But no matter what technique can be whimsical, and chainsaws are no exception. Let's take a look at more relevant predicates.
The tool stalls immediately after starting
One of the possible circumstances is the lack of fuel. Check the amount of fuel in the gas tank, and add as needed. With all this, one should strictly follow the advice of the annotation, especially with regard to the properties of gasoline and oil. In our country, such subtleties are often ignored, filling the saw with what is necessary, which causes accelerated wear of the motor and leads to failures.
Also, the saw may stall due to poor contact between the spark plug and the high-voltage wire. This can be caused by mechanical shearing or carbon deposits. From time to time it is recommended to occasionally replace the candle with the newest one, even if the old one did not show any problems in work.
The chainsaw can work normally when in a straight horizontal position, but stalls when tilted sideways. Usually this is also due to a lack of fuel: the fuel pipe rises when tilted, and if there is not enough fuel, then it rises above the fuel level.
Chainsaw stops at idle
If cleaning the muffler did not help to remove the problem, and the engine of your saw is carbureted, then you can try to set it up. the chainsaw stalls with Guys, the problem is the same, under load I forgot to say the chainsaw. On most models of engines there are adjusting bolts for coarse and fine options (H and L, respectively). By increasing the engine speed with their help, you can remove the problem. The main reasons why the chainsaw stalls when the gas is pressed. The specifics of breakdowns, methods for their solution on their own. Keep in mind that carburetor adjustment is a rather narrow process that requires the introduction of a tachometer.
Engine can't handle loads
If the chainsaw stops just in the middle of a particularly thick log, then the problem may be caused by problems in the fuel supply system or problems with the air filter. The engine just doesn't get a fairly combustible consistency to work with strong load, and stops.
The usual solutions to these troubles are the replacement of fuel in serious agreement with the advice in the annotation (we have already talked about this) and the cleaning (replacement) of the air filter.
Chainsaw stalls when revs are increased
The prerequisites for such a phenomenon are similar to the previous ones: either a problem in the fuel system, or in the air filter. Try to disconnect the fuel hose from the carburetor - if gasoline flows badly (but you know for sure that there is fuel in the tank), then the reason is in the gasoline filter. You can, at the same time, check the fuel pump - fuel should not penetrate through it. Why chainsaw stalls under load. Why the chainsaw is not gaining momentum. If this happens, then the pump is purposefully changed.
Why does the chainsaw stall
There are several circumstances Why chainsaw dies. And in paper, for some reason, it began to stall under load Chainsaw Calm 180. Repair. And, usually, almost all of them can be solved without the help of others, without going to a service center.
First, check the filters: fuel and air. If they are clogged, then this is probably the reason for the incorrect operation of the tool. At the same time, dirt is not always visible to the naked eye. Therefore, even if it seems that everything is in order, it is better to carry out this function.
The second reason may be in the candle. Do you remember the last time you changed it? According to the rules for operating chainsaws, this is supposed to be done once a year.
If this does not help, then it's worth trying to adjust the carburetor. Perhaps, from vibrations when working with a chainsaw, its factory settings have gone astray.
If she drank stalls after a long period of storage, for example, in an unheated garage, it is worth looking at the fuel line. Usually, this is a rubber tube, which can crack due to dampness and temperature changes and cause the chainsaw to malfunction.
If none of the above helped, then most likely the breakdown is more serious, and, unfortunately, you will have to contact the workshop.
What to do if the chainsaw stalls?
- Substandard carburetor operation
- Fuel System Problems
- Idle problems due to muffler failure
- Malfunctions of the cylinder-piston group
Builders, installers, rescuers and summer residents #8211 all of them, sooner or later, when performing their tasks, take up a chainsaw. And the final result of their activity largely depends on how reliably this tool will work.

Fuel and air filter problems and their elimination
The chainsaw will shut down at idle if the fuel or air filter becomes clogged. To find out the condition of the first element of the fuel system, disconnect the gas line from the carburetor. If, during pumping, fuel is delivered in doses that meet the specified standards, then the cause of the malfunction should be looked for elsewhere. why the chainsaw stalls when the chainsaw stalls, but stalls under load. If gasoline enters the carburetor weakly or does not flow out of the hose at all, then most likely the filter is clogged with debris.
For cleaning, it is removed from the tank (up to this point, all fuel must be drained from the tank). Extraction occurs through the filler neck of the tank using a wire hook. The filter is detached from the suction hose. If possible, clean the filter. If this is not possible or it is impractical to do this for a number of reasons, the used filter is replaced with a new one.

Spark plug problems and how to solve them
It is generally recommended that this key component of the ignition system be changed at least once a year. But often the owners of saws forget about this rule. And therefore, one should not be surprised that the device, the maintenance of which is carried out fragmentarily, as a result, poorly “holds” idle speed.
It is necessary to disassemble and assemble the carburetor without haste, as it contains many parts without which it cannot work.
Often, misalignment of this unit, which is responsible for supplying a certain volume of air-fuel mixture to the engine cylinder, leads to unstable operation. You can adjust it with three special screws located on the carburetor: the screws for maximum and minimum speed, as well as a screw that controls idle speed.
Some manufacturers, fearing unwanted interference from incompetent people, supply their products with only one idle screw. But in both cases, the carburetor adjustment can be made only by strictly following all the manufacturer's instructions.
However, even after adjusting the carburetor, in accordance with factory standards, this unit may junk. Then it is recommended to clean the fuel and air channels, jets, filter element mesh. If the membrane is damaged, it must be replaced with a new and high-quality one.
When servicing and repairing a carburetor, you should always remember that it is usually crammed with many very small parts, without which the device simply cannot work normally. Therefore, the disassembly and assembly of the carburetor should be done without haste and with special care.
There are several simple rules for the operation and maintenance of a chainsaw, the observance of which will maximize its service life. Preparing the correct fuel mixture, regularly cleaning filters and periodically replacing parts will save you a long time from the need to repair your tool. If it was not possible to avoid a breakdown, then you can figure out its cause completely on your own. This applies to any brands of chainsaws, ranging from the more complex Husqvarna and Stihl models to the simplest Makita and Patriot models.
Chainsaw cuts out immediately
What to do if the chainsaw stalls immediately after starting? First you need to check the presence of fuel in the gas tank. If its level is not enough, then you need to prepare the fuel mixture in strict accordance with the ratio of gasoline and oil prescribed in the operating instructions. Gasoline should have the highest possible octane rating, and the required brand of oil is usually indicated in the chainsaw's data sheet.
Next, we check the spark plug, as well as the contact of its tip with a high-voltage wire. The gap between them should be no more than 0.5 mm. If necessary, the candle is cleaned of soot and dried. It is recommended to occasionally change the candle to a completely new one. The reasons why the tool stalls when you press the gas lie in the fuel filter or carburetor jet. Cleaning the gasoline filter will not take much time and effort, but it is better to entrust the disassembly and cleaning of the carburetor to the specialists of the service center.
Chainsaw stalls at idle
There are cases when the chainsaw stalls at idle. First of all, you need to check the muffler, and, if it is dirty, clean it from exhaust tar deposits. Also on the carburetors of some models, etc. there are bolts with the inscriptions H and L - respectively, coarse and fine tuning. By adjusting the bolt L during the operation of the chainsaw so that its speed increases (it is enough to turn the bolt only half a turn), it is possible to eliminate this problem. Adjusting the carburetor requires the mandatory presence of an electronic tachometer and is a rather time-consuming process. That is why in such cases it is better to turn to professionals.
Chainsaw stalls under load
If the chainsaw stalls under load, the fuel system or a dirty air filter may be the cause. Changing the fuel with the correct ratio of gasoline / oil or cleaning the air filter are universal solutions to this problem. An improperly prepared mixture of low-quality gasoline and, for example, engine oil is the main cause of chainsaw malfunction, including when it heats up and stalls.
Chainsaw stalls when tilted
When the chainsaw is in a horizontal position, the fuel pipe lies at the bottom of the gas tank, but when the tool is tilted, the pipe is above the fuel mixture, i.e. in the airspace. This is what causes the chainsaw to stall on its side.
Chainsaw stalls at high rpm
In the event that the tool stalls at high speeds, it is necessary to check three parts: the air filter, the fuel pump and the gasoline filter. The air filter must be cleaned, you can even wash it under water and dry it thoroughly. Then it is enough to disconnect the fuel hose from the carburetor and see if fuel flows out of it or not. If it flows in a full stream, the gasoline filter can not be checked. Otherwise, the error has been found. The breather can be cleaned with an ordinary needle, and the filter can be carefully disconnected from the suction hose, cleaned or replaced with a new one. The gasoline pump is checked for wear: if fuel does not seep through it, then everything is in order with it. If the problem that your tool stalls at full speed is due to some damage to the pump, then this item you just need to replace it with a new one.
There are frequent cases when owners of chainsaws are faced with their breakdown and it does not matter at all what model of this kind of equipment, since the nature of the breakdowns is almost the same for everyone. Well, the chainsaw has stalled, and what's next? Undoubtedly, you can take the equipment to specialized services that will fix your "iron friend" for a fee. But as they say: why pay more?
After all, you can personally disassemble the tool and repair it, since the breakdown can be insignificant, and in the service you will pay a lot for this. But naturally, in order to bring the instrument back to life, you need to be able to understand the causes of its breakdown and how to troubleshoot it. So let's learn! In this article, you can find answers to questions regarding situations where the tool simply stalls after directly pressing the gas. So let's get started.
The main elements of chainsaws
Before starting to delve into the issues of breakdowns and repair of the tool, let's first figure out what the actual chainsaw consists of. First of all, I would like to note that this tool belongs to the category of equipment, the operation of which directly depends directly on the internal combustion engine.
Just as important is that chainsaws are equipped with a single-cylinder engine, and the work of which is carried out on such a fuel as gasoline. It is worth noting that, despite the similarity with other tools, it does not have a gearbox. And it is replaced by a kind of single-stage chain transmission, through which the movement of the chain itself (saw) is performed.
In fact, a chainsaw is a fairly simple design, but this does not prevent it from being reliable, practical and able to fully ensure immediate uninterrupted and cyclical operation even in rather difficult conditions. This tool consists of a huge range of certain elements "vital" for its correct and productive work. This is a carburetor, a direct chain tensioner, a tire equipped with a chain and other elements.
Characteristics and possible causes of failure. Fixing the problem with your own hands
Chainsaws are fairly reliable and simple designs. Therefore, if you properly care for them and handle them based on the manufacturer's recommendations, then they fail very rarely and various kinds of breakdowns are quickly eliminated. But if you are faced with this situation and want to repair your instrument yourself without resorting to the help of professionals, then delve into the information below.
In fact, it is impossible to unambiguously and accurately determine the reason why or stalls when you press the gas, as there are a lot of factors affecting this. But do not forget that, starting from the fact that the chainsaw is equipped with a simple two-stroke engine, conditions such as lubrication, fuel, spark and air are important for its effective performance.
Consequently, the carburetor is directly involved in the preparation of the fuel-air mixture, the filter cleans the air from dust, the ignition unit and the candle create a spark, and there is lubricant in gasoline.
- It is also important that for the trouble-free operation of the tool, it is necessary to pay close attention directly to the fuel. Since if this kind of mixture is not prepared correctly, then most chainsaws simply will not start. Consequently, not every owner will guess to look for the cause of the breakdown in the fuel. That is why, in order for your tool to always work correctly, you need to use only high-quality gasoline for the mixture.
And also use only the oil that is made by the manufacturer of your tool. In addition, it is important to prepare this kind of mixture in the amount that you definitely use in one or two weeks, but not more (see).
Otherwise, overexposure of the mixture directly in the canister will cause it to lose all its octane properties and this will lead to significant problems with the tool.
- Also, the cause of the breakdown can be a direct filling the mixture with a candle at the moment when the mechanism is started. In order to solve this problem, it is necessary to turn out and dry the candle, but remember that it should not be ignited in any case. Excess fuel must be drained through the hole (candle), wait 20-30 minutes, then install it in place and try to start the tool again.
- The chainsaw stalls when you press the gas due to the fact that no spark. This can happen when there is no good contact between the tip of the spark plug and the wire (high voltage). However, if this kind of connection works correctly, but there is still no spark, then the ignition unit (electronic) is the cause. It is important to note that these types of spare parts cannot be repaired, so they can only be replaced.
Do not forget that by examining the candle, you can get significant information regarding the breakdown of the chainsaw. Since if its surface is dry, then the reason for this is a cylinder into which fuel is not supplied directly. That is why you will have to step by step check the entire range of its supply. If the candle is all black soot, then this means that the carburetor is not working properly, that is, it either supplies a lot of fuel or pours oil directly into gasoline.
- If the chainsaw stalls when adding gas, then this means that fuel is supplied in insufficient quantities for the full operation of the chainsaw. This can be caused by both clogging of the carburetor (its jet) and contamination of the filter itself (fuel). Remember that the first node should only be checked by professionals, but you can clean the second one yourself.
- In addition, the cause of failure can be filter (air) if it is contaminated with dust. But do not forget that each model has its own easily eliminated and characteristic features. For this reason, do not hastily start disassembling and repairing the instrument, but it is best to “walk” through the forums, where reviews of various owners are indicated in large numbers, so as not to make things worse.
Since, for example, a chainsaw stalls when you press the gas for a simple reason, namely, a simple clogging of the direct breather.
In order to solve this kind of problem, all you have to do is disconnect the (fuel) hose from the carburetor and pay attention to whether fuel is leaking from it. Since if the mixture flows in a full stream, this means that the breather is not contaminated, and if vice versa, then the cause of the breakdown has been found.
- Here is another reason why the chainsaw stalls when you press the gas - muffler. It is this part that can interfere with the full operation of the tool in cases where it is directly contaminated with exhaust resinous deposits. To do this, you just simply need to clean it.
- Quite often, the chainsaw partner stalls when pressed and the reason for this is cylinder-piston group. Since by examining them, namely the piston and cylinder, you can easily determine the cause of a tool malfunction, directly by replacing them. You can also make a direct bore of the cylinder itself relative to the dimensions of the new piston.
But if after inspection you find that both the piston and the cylinder do not have any damage, in this case the reason may lie directly in the rings (piston). For this kind of check, it is necessary to insert the piston into the cylinder and gently begin to swing it through the connecting rod. If suddenly you feel a backlash, then the rings need to be replaced, as they have already worn out.
- Many people ask: why does the chainsaw stall when I press the gas? The answer may also lie in insufficient chain lubrication(see), as the oil line may leak, or the direct channels may simply be clogged. That is why pay attention to the chain, because if it is dry, then, without delay, begin to clean the channels that supply oil directly to the tool bus. After that, inspect in detail the parts where the oil pump fittings are connected to the pipes. But if you notice that the oil is leaking at the joints, or you find cracks on the tubes themselves, then in the first case, seal the leaks with sealant, and the tubes will have to be replaced.
First of all, what you should remember when purchasing this kind of tool is that certain saw parts must be replaced with new ones after their service life (passport) has ended. It is for this reason that the instruction should always be at your fingertips, since everything is described in detail there.
Such details include: sprocket (drive), tire, part of the system (anti-vibration), as well as the chain. Since you should not forget that if this “stuffing” is not replaced with a new one at the right time, then these worn parts will negatively affect the rest of the chainsaw. For this reason, check the depth of the direct tooth development quite often. Remember that it should not be higher than a week of 0.5 mm.
Summing up…
Definitely, every thing we buy has its own expiration date and sooner or later it breaks down, and it becomes a shame when the degree of its breakdown is so great that it cannot be repaired. But you must admit that quite often we are simply negligent about technology (see about proper operation and about that), and when it stops working, then we try to find ways to fix breakdowns, while turning to a huge number of services.
But remember that even though the equipment breaks down, we can extend its “life”. All that is needed is to simply take care of it, do a break-in after replacing parts (read how it happens here) and keep its parts clean and tidy. And then, of course, it will last for many more years. It is also important to use exclusively high-quality spare parts and "additives" (see). Then your equipment will work smoothly, and you will simply forget what repair is.
