Stihl starts and stalls when pressed. Checking the main chainsaw systems

20th June 2023

Why stall the chainsaw engine

Basil stalls when you press the gas

One of the most common questions. In this case, it is necessary:

Check the fuel filter.
Inspect the fuel hoses for tightness.
Check the muffler.
Try to add a little speed xx.
Look at the rubber seals on the crankshaft, the spacer between the carburetor and the cylinder.

Basopile stalls “on hot”

If the chainsaw is well started until heated, and after he is heated, it begins to stall and does not start until it cools down, then the problem may be as follows:

Check if there is a suction (hoses, seals, gaskets)
See the muffler for a bunk.
Check the CPG (cylinder-piston group) for bullying.
Check the carburetor settings
It is still possible that the ignition coil failed. Когда пила нагревается, то возрастает сопротивление и искра или теряется или становится настолько слабой, что ее мощности не хватает для воспламенения смеси.

Basil stalls under load

If your saw starts up well, works both on idle and when adding “gas”, but barely worth it to give the load stalls, then the following steps should be taken:

Check the fuel filters
Adjust the carburetor
Check hoses, gaskets and seals for suction
Check the clutch

Problems with the candle of ignition and ways to solve them

Typically, this key component of the ignition system is recommended to be changed at least once a year. But often the owners of the saw forget about this rule. And therefore, do not be surprised that the apparatus, the maintenance of which is fragmented, as a result, does not “hold” idle turnover.

The spark plug of the chainsaws must be changed 1 time per year.

Flooding the candle with gasoline at the time of launch. Иногда пила глохнет на холостых оборотах, что бензопила без проблем заводится без. To eliminate the problem, they turn the candle and, without calcining, dry it. Through the hole, into which the candle is screwed, excess gasoline merges from the engine. After a break in 30 minutes, the candle is installed in place, the mechanism starts.
Lack of spark due to poor contact of the tip of the candle with a high voltage wire. The connection is checked, in case of violation, the defect is eliminated.
There is no spark due to a malfunction of the electronic ignition unit. If there is confidence in the reliability of the tip of the tip with a high-voltage wire, but there is still no spark with the starter on, then the ignition block malfunction may be the cause of the breakdown. This component is not restored, it is only changed to a new.
Incorrect gap between candle electrodes. In different types of candles, this indicator ranges from 0.2 to 0.5 mm. The correct gap is installed using the probe of the corresponding thickness. Basil stalls stalling a chainsaw stall at large speeds. In that case. A larger or smaller gap for a given type of candles is not allowed.

Meanwhile, during the initial examination of the candle, it may turn out that the reason why the chainsaw refuses to work is not at all in the defects of the candle or other elements of the ignition system.

Spark plugs can tell about the drop malfunction.

So, if the candle is completely dry, this may mean that the initial problem lies in the impossibility of fuel intake into the combustion chamber. In this case, you should check the entire gas supply circuit from the carburetor itself.

At the same time, the presence on the case of a candle of a characteristic black haze #8211 is a sign that the carburetor is probably poorly adjusted. Because of this, the fuel mixture turns out to be oversaturated with gasoline. Perhaps oil got into the fuel. In this case, you should clean the candle, replace the fuel and adjust the carburetor.

Why the stihl chainsaw is not started

For preliminary diagnosis of causes, the gas pump is checked, the appearance of the candle, fuel flow, carburetor functionality and filter condition. Pay attention to the performance of cylinders, pistons, muffler, crankshaft bearings. After preventive measures, they try to launch a chainsaw. Insufficient lubrication of rubbing spare parts also becomes a factor of poor work.

Lack of sparks

Sparking is being checked on the spark plug. The functioning of the element is affected by different factors. When testing the mechanism, the reasons are revealed:

Due to work in such conditions at the contacts, the candle accumulates. The subsequent corrosion of the conductors becomes the reason that there is no spark in half of cases of malfunctions. This is because the gap between modular contacts changes. To check the spark, they make the following:

The tip of the high.voltage cable is removed;
the candle is twisted;
The tip is put in place;
The candle is leaning with a wide end against the cylinder;
Start the starter.

The ignition coil malfunction

The module or coil does not understand, its suitability is difficult to identify without testing devices. Modern ignition systems are strong, light and small in size. They are characterized by almost reliable functionality. Problems with a malfunction of the chainsaw due to the ignition coil can be eliminated independently.

Test the outlet wires for damage (in t. h. internal) that arise due to vibration leading to friction. If there are no cracks, then the ignition coil replacement is required. Sometimes a weak, barely distinguishable flash when heating the saw indicates a malfunction of the module. This is due to an increase in the temperature of the coil, which leads to an increase in the resistance of the transistor.

The peculiarity is that at the beginning of the spark, the spark may appear, but after prolonged use it becomes dull and disappears. Modern ignition coils in a home workshop are not repaired, therefore they are changed to suitable elements.

Fuel supply

After twisting the candle on its surface, a wet plaque is detected. This speaks of excessive supply of gasoline to the combustion chamber. For this reason, the tool does not work or stalls, t. to. Fuel is not ignited.

Another inhibitory factor is the clogging of the sapun. a small hole in the lid of a gasoline tank. It is cleaned with a needle, otherwise the chainsaw of the Stihl MS 180 does not start. To determine incorrect fuel supply, consistent actions are carried out:

remove the candle;
2 cubes of gasoline are poured into the candle hole with a syringe;
put a device for ignition in place and put on a cap of a high.voltage wire;
The lever is transferred to the position of hot launch;
Twist the starter handle a couple of times.

If the tool starts and stalls immediately, then the fuel highway is tested further. Check a gasoline filter, a surge from the engine crankcase, the integrity of the partition in the pump when unscrewing the cover.

The breakdown of the crankshaft bearings

With defects in the bearings, a weak play is felt. To identify it, the flywheel of the STIHL MS 180 saw is staggering from one side to the other. The movement suggests that the flywheel shifts towards the electrodes with its own magnets, as a result of which there is no spark. To remove the mechanism, dismantle the cutting element, remove the filter lid and clutch. For the crankshaft, the lid of the manual starter is removed and two bolts are pulled.

The clutch is twisted with a clock clockwise. Remove the drum with an asterisk, change the old clutch and twist it all the way. The crankshaft are stopped so as not to break the starter. The mechanism is assembled in the reverse order. To tighten the brake handle is tilted forward, the tool is started, then removed from the brake.

Less commonly detected bearings with marriage (in the clip, the diameter of the holes is increased). To determine, disassemble and measured using a micrometer. A regular knock testifies to broken bearings. In this case, urgent repairs are required, t. to. In case of violation of the integrity of the crankshaft, a piston group and cylinder will fail.

Flies a candle of ignition

In this case, the spark is not able to ignite the fuel, which in large quantities enters the firebox to burn the combustible mixture. If it floods the candle, then the carburetor is faulty or the cold motor is launched incorrectly. The engine is made, the procedure is performed with the ignition turned off and far from the open flame. To ensure fuel ignition at the time of start.up, they clean the mechanism:

They twist the candle, wipe dry, dried for half an hour;
A large layer of carbon fiber is removed with a file;
Between the contacts, the gap is regulated;
The tool is turned upside down and gasoline is drained;
In this position, the starter is twitched several times (to remove fuel residues);
They are assembled in the reverse order.

When the first signs of power loss (reduction of revolutions) appear with a chainsaw STIHL MS 180, in no case should you continue to work, but you must immediately contact specialists or conduct diagnostics and eliminate the malfunction on your own. There are not so many reasons for loss of power and you can cope with them without even having certain skills. The main thing is to calmly analyze the behavior of the saw and find out the reasons why it stopped pulling (the speed has fallen), and to eliminate the malfunction is already a simple thing.

There are frequent cases when the owners of the chainsaw are faced with their breakdown and it does not matter what kind of technique of this kind of technique, since the nature of the breakdowns has almost everyone the same. Well, here the chainsaw was stalled and what’s next? Undoubtedly, the equipment can be attributed to specialized services that will fix your “iron friend” for a fee 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 for this you will pay a lot. But naturally, in order to return the tool to life, you need to be able to understand the reasons for its breakdown and ways to eliminate malfunctions. So let’s study! In this article, you can find answers to questions regarding situations where the tool simply stalls after direct pressing for gas. So, let’s get down.

Why is a gasoline saw go out when I press on gas: causes and solutions

Often, the owners of the chainsaw have to deal with their breakdown, and it does not matter which model of this type of equipment, since the nature of the failures is almost the same for all. Well, this is a chainsaw stalled and what’s next? Undoubtedly, you can include equipment in specialized services that will repair your “iron friend” for a fee. But, as they say: why pay more?

In the end, you can personally disassemble the tool and repair it, since the breakdown can be insignificant, and for this you will have to pay a lot. But, of course, in order to return the tool to life, you must be able to understand the reasons for its refusal and how to eliminate it. So let’s study! In this article you can find answers to questions about situations where the tool simply rushes after a direct touch of gas. So let’s start.

The main elements of the chainsaw

Before we begin to understand problems with the breakdown and repair tools, let’s first find out what the chain came from. First of all, I would like to note that this tool belongs to the category of equipment whose work depends directly on.

It is also important that the chainsaws are equipped with an engine with one cylinder, and whose work is done on fuel such as gasoline. It is worth noting that, despite the resemblance to other tools, he does not have a gearbox. And it is replaced by a kind of chain single.stage gearbox through which the movement of the chain itself (saw) is produced.

In fact, chainsaws are a fairly simple design, but this does not prevent it from being reliable, practical and capable of fully ensuring immediate continuous and cyclic work even in rather difficult conditions. This tool consists of a huge range of certain elements of “vital” for proper and productive work. This carburetor, device for. Tire equipped with a chain and other elements.

Before buying a chainsaw, be sure to study all the options and select a suitable brand of a chainsaw.

To simplify your choice, we have made a chainsaw rating for you for reliability.

If you have a limited budget, read the article about the manufacturers of the chainsaw.

Characteristic and possible reasons for the refusal. Eliminate the problem with your own hands

Chainsaws. Pretty reliable and simple design. Therefore, if you carefully take care of them and deal with them based on the recommendations of the manufacturer, then they fail, very rarely, and quite quickly, various types of failures are eliminated. But if you are faced with such a situation and want to repair your tool yourself without addressing professionals, read the information presented below.

In fact, it is impossible to unequivocally and accurately determine the reason why the tool does not start or kiosks when you press the gas, since many factors affect this. But do not forget that starting with the fact that the chainsaws are equipped with a simple two.stroke engine, conditions such as lubrication, fuel, spark and air are important for its effective operation.

Therefore, the carburetor directly participates in the preparation of the fuel-air mixture, the filter cleans the air of dust, the ignition and the light of the ignition create a spark, and the lubricant. In gasoline.

Therefore, it is necessary to look for the reasons for this kind of breakdown in a sequential order, starting with simple and gradually moving on to complex. And this is an important factor in proper repairs, since a person who, not taking into account this, begins to analyze the carburetor, is at risk. Since this type of device must be repaired or adjusted directly in special workshops (read about the tuning of the carburetor).

It is important that for the non.precise operation of the device it is necessary to directly process the fuel. Since, if such a mixture is not prepared correctly, most chainsaws simply will not begin. Therefore, not every owner will guess the reason for the fuel failure. Therefore, in order for your tool to always work correctly, you need to use exclusively high.quality gasoline for the mixture.

Nagaz repairs of the blinzopila and just use the oil produced by the manufacturer of your tool. In addition, it is important to prepare the type of mixture in the amount that you use for one or two weeks, but no more (see. A share of gasoline and oil for a chainsaw).

Since otherwise the excess mixture directly in the canister will lead to the fact that it will lose all its octane properties, and this will lead to significant problems with the tool.

In addition, the cause of the violation may be direct filling out the candle mixture during the operation of the mechanism. To solve this problem, it is necessary to unscrew and dry the candle, but remember that it cannot be burned in any case. Excessive fuel should be merged through the hole (candle), wait 20-30 minutes, then set it in place and repeat the attempt to start the tool.
Chainsaws stop when you press the gas due to the fact that there is no spark. This can happen if there is no good contact between the tip and the wire (high.voltage). However, if such a connection works correctly, but sparks still do not exist, then the whole reason. This is the ignition unit (electronic). It is important to note that such spare parts cannot be repaired, so they can be replaced. Checking a candle

Do not forget that by studying the candle, you can get important information about the breakdown of the chainsaw. Since, if its surface is dry, then the reason for this is a cylinder that does not directly supply fuel. That’s why you should in stages check the entire range of your ideas. If the candle is in black carbon, this means that the carburetor works incorrectly, that is, it supplies a lot of fuel or pours oil directly into gasoline.

Why stalls idle

The first and most common cause of this malfunction is the wrong carburetor adjustment. You can adjust the idle speed yourself, for this you need to have a STIHL adjustment screwdriver, which comes with the unit. The adjusting hole is located on the right side of the STIHL 180 saw on the handle and is indicated by the symbols “-” and “”.

If the Stihl chainsaw does not hold turns and stalls at idle, you can almost 90% be sure that it has violations in the system of the fuel pump, as a rule, it is an air leak into the crankcase through the lining of the pallet, or, much more often, through the seals crankshaft. The air leaks reduces or even completely stops the impulse, which is supplied through special channels to the fuel pump of the chainsaw. As a result of this, the Stihl 180 chainsaw does not receive the required amount of fuel and stalls at idle.

Diagnose, you can use a special device called a vacuummeter.

The second way to check the operability of the oil seals is to pour gasoline into the engine crankcase and look at them if the oil seals are gasoline, then they cannot provide normal pressure in the crankcase, which will make the work on idle it is impossible. And when working at high speeds, with leap omentels, there is a possibility of jamming of crankshaft bearings.

The algorithm for checking the crankcase and seals STIHL 180 for tightness is as follows:

The upper cover is removed.
Air filter housing and carburetor are dismantled.
The handle of the chainsaw is removed.
Spin and removes the starter.
The side cover and leading star are removed from the opposite side of the side.
A piston lock is installed in the candle hole or a lace from an old starter with nodules imposed on it is filled into the cylinder.
The flywheel and clutch are unscrewed, after which the details are removed. It is worth knowing that the clutch of the chainsaw has the left thread and is unscrewed clockwise.
The gear of the oil pump drive is removed.

Reasons why the chainsaws start and stall

Basil for a long time is not a luxury, but a necessary tool for those who have a country site or home ownership. But, like any other technique, this tool has the ability to fail, despite a simple device.

The classification of the main malfunctions includes:

The complete absence of engine plant
The engine starts and Glakes
Unstable work of the tool
Stop work at load
Loss of power.

If the chainsaw does not start at all, the reason may be as follows:

Manufacturing defect
Lack of fuel
Problems with the launch of the ignition system
Lack of spark from the spark plugs
Poor.quality fuel mixture
Clothing carburetor
High.voltage wire problems
Lack of compression.

Why is the chainsaw starts and stalls, what to do in this case? It is necessary to consider in detail the reasons for this.

The chainsaw starts and stalls: reason, video

The reason that the chainsaws may stall immediately after the plant lies in the problems of a certain part of the equipment.

The most banal reason why the chainsaws started and stalled is a low fuel level in the tank. Confirmation of this may be the stop of the tool when tilted, when fuel remains accumulate in a certain place of the fuel tank. With poor.quality fuel, a problem with the operation of the chainsaw may also arise, in this case it is necessary to completely replace it.
Blockage of the saopun, which significantly reduces the fuel consumption to the engine.
Insufficient contact of the cap with a candle, which leads to a strong heating of the candle insulator. Contact deterioration may occur due to mechanical shift or soot.
Damage to the spark plugs.
The muffler is blockage, due to which the output of the exhaust gases, leading to the stopping of the engine operation, deteriorates. For this reason, a chainsaw can start and stall at idle. The sediment in the muffler can also appear due to poor-quality fuel or improper operation of the tool.
Bad adjustment of the carburetor.
Damage to the piston group
Problems with a fuel filter or pump. In this case, gasoline can flow through the pump or poorly flow through the fuel filter to the carburetor. As a result, the chainsaws are starting to stall with an increase in speed.
Air filter pollution. Problems with this element of equipment lead to the fact that, with increased loads on the engine, he simply does not cope with them due to blockage and stops. A similar result is also obtained with an increase in speed.
Closing the chain due to the absence or insufficient amount of lubrication, as well as problems with the brake of the chain.

Why the chainsaws are poorly starting and stalling

With poor starting the equipment “for a cold” problem, the problem may be in the absence of compression, t.e. the rings are worn out due to a long service life, their replacement is required. Sometimes the reason that the engine is poorly started in a warmed state is the problem with the silencer, as well as poor contact between the candle and the wire.

Also, the reasons for poor starting can be wear or damage to the gasket, rubber cuff in the accelerator pump of the carburetor, which causes an additional air flow that leads to an increase in the speed of the saw.

Elimination of problems

The operation of the equipment should be correct, with a periodic inspection of the constituent elements to prevent breakage. To eliminate problems, it is necessary to check all the components of the equipment for their functioning.

If the chainsaws start and stall, the reason can be eliminated on its own. If it consists in a lack of or incorrectly prepared fuel mixture, it is necessary to fix it. For prevention during the downtime of the chainsaw, you should always drain the remaining fuel.

It is necessary to carry out a periodic check of spark plugs. In this case, it is necessary to remove the soot that scores the clearance of the connection, as well as check the tips for the presence of fuel. Another cause of malfunctions with the spark plugs may be their wet with gasoline. To do this, they need to be removed, wiped with a rag and leave to dry. Faulty candles are replaced.

In the absence of a spark between the spark plug and a high.voltage wire, but if there is a good connection, it is necessary to replace the ignition unit.

The muffler’s blockage is a common cause for a breakdown in which the chainsaw is started and immediately stalls. To eliminate the malfunction, it is necessary to dismantle the silencer, clean it from the carbon for sandpaper or a special chemical solution. If the model of the chainsaws is indifferent, chemicals are poured into the system and there are several hours there, then it is blown.

The carburetor must be adjusted if the chainsaw stalls at idle. Accurate setting is a rather time.consuming process, so it is usually done in service centers. But, on some models there are elements for its configuration, it is enough to turn the bolt by half a turn to increase the speed of the chainsaw, the problems will be eliminated. In case of suction, nozzles, channels and filters must be disassembled and cleaned by the entire carburetor. With the wear of the seals, gaskets, cuffs, it is necessary to replace them by preventing the “suction” of air.

If problems with a fuel or air filter occur, it is necessary to replace the fuel pump or clean the air filter.

When clogging the soundtress, it is necessary to clean it with a regular needle.

And immediately stalls, the reason may lie in the wrong operation of the chain. To eliminate the problems, the presence of oil in the container for lubrication of the chain, as well as the oil.outlet tube for ruptures or blockage, is checked.

Verification of filters and carburetor

Frequent cause of flexions of the chainsaw are malfunctions of filters or carburetor.

Checking the fuel filter

If the fuel filter is clogged with dirt, it is not able to let through a sufficient amount of fuel through itself. As a result, the chainsaw stalls if you press the gas. The fuel burns too fast, and its new portion does not have time to enter the system. If the fuel filter is noticed slightly, a significant decrease in power at maximum engine speeds is observed.

The fuel filter of the chainsaw

Air filter

Pollution of this element makes it impossible to normal operation of the chainsaw. But many models are equipped with a special compensator that carries out air fence in another way. It allows you to do this even with a contaminated filter, which positively affects the operational capabilities of the unit.

The location of the air filter and the spark plug of the chainsaw

In such cases, the saw power falls significantly, but it will not stall. Sometimes a decrease in this characteristic is observed during the wear of the piston.

Carburetor

A common cause of malfunctions of such a tool is called carburetor breakdown. Checking this element is recommended to do if there are certain skills. It is better to give the device to a specialist who will perform high.quality diagnostics and configuration using a tachometer.

This is especially true when the saw stalls at idle. It is recommended to check the muffler operation. It is precisely because of the accumulation of exhaust gases that the saw stalls at idle speeds and does not work normally. Very often it happens that they don’t use a saw for a long time. When they begin to operate it again, they notice that when starting at idle, the unit works well, and when you press the gas, it stalls. The main reason for such a negative phenomenon is a stabbed Form Found.

To check the presence of such a malfunction, it is necessary to remove and disassemble the carburetor. To do this, unscrew two nuts where the air filter was mounted. It is removed with the engine control lever. The craving for control of the air damper from the carburetor is necessarily disconnected.

Removing the carburetor cover

At the next stage, this part must be slightly pulled over, disconnecting the fuel hose. This must be done especially carefully, having previously prepared a special plug. It will come in handy to close the hose, since fuel will be released from it.

When it was possible to remove the carburetor, it needs to be cleaned of dirt and blew on it. Only then can you try to promote this part. It is necessary to remove the main cover and with a small bolt should be carefully knitted the valve. He must pass the air in only one direction. If it passes on both sides, then it is necessary to replace this part.

Partner 350 chainsaw starts and stalls

Why is the chainsaw stall when you press the gas?

Hello! If you find yourself on this page, then, apparently, your chainsaw stalls when pressing gas, and for you to find out why this is what is happening and what to do with it. What, after all, I’ll try to help you in this dilemma, having dismantled the more proven prerequisites for such a raki, as well as ways to eliminate them.

To begin with, I will immediately write for new users that many chainsaws before work asks for a heating of the motor at idle for approximately one minute. Why is the chainsaw starts and stalls. Causes and. Here the chainsaw is stalled and does not start or stall the chainsaw stihl stalls. Until the engine is heated, the saw can stall when gas is added.

So, if a heated chainsaw can work at idle, but stalls at a load, this means that:

The carburetor is incorrectly configured or clogged. the most frequent case;
She lacks air, the consumption of which increases sharply with increasing speed. this means that the air filter is contaminated (the case is rare, because the filter pollution occurs evenly, because the user initially notices the loss of power);
She lacks fuel, the consumption of which also increases with increasing speed. this means that the fuel filter (also an infrequent case) is contaminated;
Well, the most nasty case, if there is excessive friction between the piston and the wall of the cylinder, associated with a shortage of oil in the fuel consistency. after such a chainsaw you are most likely to fly to the repair of the piston group, because clogs that impede the piston and walls of the cylinder that impede the piston and walls of the cylinder work of saws.

Little oil in the fuel mixture

At first we will analyze the most nasty case. Why? Since it is better to make sure that oil and gasoline are mixed in the correct ratio before doing filters manipulations with filters.

Here, however, it is worth seeing that if your saw has already been repeatedly (for example, 10 times) has been opened by you, but continues to start, and later stall again with an increase in revolutions, then with fuel, apparently everything is in order. The reasons for the lack of lubrication on the Partner 350 chainsaw are somewhat and floods the candle. In an unpleasant case, she would just finish starting to start.

Read why the chain is stretched on the chainsaw

But all the same, I recommend that I immediately dispel the smallest doubts about the properties of fuel, as I drank it stalled when the revolution is recruited for the first time. Since, if the reason is fuel, then, as already mentioned above, you can get to expensive repairs. And so, it can still do. Dispersing doubts is to drain old fuel from the tank and pour freshly prepared, in which oil and gasoline are mixed in the correct proportion.

The correct ratio is better to look in the annotation to the saw. What to do if the chainsaw starts and stalls. Quite often Partner chainsaw stalls when pressed and a chainsaw is not started. Watch the disassembly of the chainsaw 350 S (in the video Partner 352, the chainsaw is not started. STIHL 180, Partner and others will not start. If you are lost, then we look at the ratio on the oil packaging. It usually happens 1:50 or 1:40. Why stalls the chainsaw with a load of a chainsaw starts and stalls, the cause of the chainsaw for a long time is not a luxury, but the necessary tool for anyone who has at least some kind of country. If the oil is used “non.native” (well, for example, for the chainsaws of the STIHL “native” will also not be enough STIHL), I recommend using a proportion of 1:40, even if 1:50 is written on the packaging with oil.

After preparing a new mixture, drain the previous mixture from the tank, in which we are insecure, and fill the freshly cooked.

Now that you have done everything to dispel any doubts about the quality of fuel, we proceed to further actions.

As I already wrote above, with a lack of oil on the piston and walls of the cylinder, scuffs can form. and almost always form. The chainsaw is started and the Chinese does not start why the chainsaw is starting and stalling. If you are lucky, and the bullys did not appear, then with a new fuel mixture prepared in the correct ratio, the chainsaw should begin to work normally.

If the bullying appeared, then the saw can start and stall several times, after which it will stop starting up. In such a situation, I sympathize with you, since, most likely, now you will need to make a replacement for a piston group that will cost a lot.

If the saw, as before, starts and stalls at high speeds, then we carry out manipulations with filters.

The air filter is contaminated

Moving in the contamination of the air filter is quite easy. You just need to remove it and start a chainsaw without it. if the saw works normally, then then the matter is in it and it just needs to be changed or washed, depending on its type. And do not be afraid that the chainsaw will work for a while without protection against dust. if there is no dust cloud around you, then everything is in order.

So, remove the air filter. The main reasons why the chainsaws stall when it does not start and stalls like STIHL and. The main reasons why the chainsaws stall when it starts and stalls, and Partner. To do this, you need to remove the lid from the back of the chainsaw, which is attached either with screws, or just with some kind of fixer that you just need to turn or jerk off.

If when the filter is removed after the drain, the saw works normally, then it means it is contaminated.

In this article, we will consider the main problems that can occur when the stihl chainsaw is launched (the spark has disappeared, the tool stalls or does not gain momentum), as well as ways to eliminate them.

Lack of sparks

Sparking is being checked on the spark plug. The functioning of the element is affected by different factors. When testing the mechanism, the reasons are revealed:

The tip of the high.voltage cable is removed;
the candle is twisted;
The tip is put in place;
The candle is leaning with a wide end against the cylinder;
Start the starter.

The ignition coil malfunction

Fuel supply

remove the candle;
2 cubes of gasoline are poured into the candle hole with a syringe;
put a device for ignition in place and put on a cap of a high.voltage wire;
The lever is transferred to the position of hot launch;
Twist the starter handle a couple of times.

If the tool starts and stalls immediately, then the fuel highway is tested further. Check a gasoline filter, a surge from the engine crankcase, the integrity of the partition in the pump when unscrewing the cover.

The breakdown of the crankshaft bearings

Flies a candle of ignition

They twist the candle, wipe dry, dried for half an hour;
A large layer of carbon fiber is removed with a file;
Between the contacts, the gap is regulated;
The tool is turned upside down and gasoline is drained;
In this position, the starter is twitched several times (to remove fuel residues);
They are assembled in the reverse order.

Stihl chainsaw stalls: reasons

If the tool is turned off immediately after starting, then there was a breakdown of a device or part. To determine the reason, the mechanism is tested independently or in service workshops. Sometimes the reason that the mechanism starts poorly is the improper service of the saw:

insufficient volume of gasoline;
poorly cooked fuel mixture;
poor lubrication quality;
muffler clogged by combustion products;
unresolved carburetor;
air filter obstruction;
Piston or cylinder malfunction.

When pressing gas

Speaking units work at idle, but the motorcycle stalls when the gas is pressed, t. to. The load rises. The tool is heated before use, driving off the engine at idle for a minute. If this is neglected, then the motor stops after pressing the pedal. Other reasons can be:

a clogged or unresolved mixing unit of fuel fuel;
The clogged air filter does not give the desired air flow when the load is increased;
a contaminated gasoline filter does not miss the required amount of the mixture;
the wall of the cylinder and the piston rubs.

Low octane fuel number causes the brake, t. to. This circumstance does not allow the motor to achieve the required power when increasing the load.

At idle

Violation of the functionality of the fuel unit system leads to an air leakage. In this case, the unit stalls at idle and does not hold their number. An additional suction reduces the air pulse to the fuel pump and passes through the membrane of the pallet or crankshaft oil seals. Diagnosis is made by vacuum.

The stopping of the engine is on the cold for other reasons:

The candle channel contains an excess amount of combustible mixture;
A gap is not adjusted between the tip of the candle and the high.voltage cradle;
Failure of power supply.

Check the seals, pouring gasoline into the crankcase, the leak is visually visible. So, the engine does not work at idle, and at a high frequency, leaky oil seals will lead to jamming of the bearings. In the case of elements, they are replaced with new ones and sealing.

At full speed

Sometimes the engine stalls after normal operation. To establish the cause, pay attention to related circumstances:

The motor stalls in the middle of work for no apparent reason. The starter is in a fixed position and does not turn. So, the tool is jammed and requires urgent repair.
During normal operation, the power is reduced in a short time and the engine stops, the cylinders are overheated. The situation indicates the occurrence of an air suction under the rubber pipe between the carburetor cylinder, possibly due to the gap. Air impoverishes fuel, it requires replacing the pipe.

He is not gaining momentum

A lot of mechanism systems are involved in launch, so the loss of the stiHL chainsaws after operating at idle may become a consequence of various factors. Confident work of idle and interruptions in the motor with a load can arise for the following reasons:

engine resource development;
wear, deformation and corrosion of the piston group;
malfunction of the ignition or candle coil;
Balance of carburetor screws.

If the tool does not develop speed, then the conductivity of the hole in the lid of the tank for fuel is disturbed. The emergence of a vacuum does not give the right amount of fuel, because the engine does not gain the required power. The revolutions are reduced when the carbon monoxide is accumulated in the muffler, it is difficult to remove gases from combustion.

Does not drop in momentum

The tool quickly reaches the maximum speed, and the power is not reduced. This situation is explained by the fact that:

the throttle does not work due to the weakening of the spring or traction element;
periodically refuses the tooth controller;
There is no corkscrew on the axis of the throttle;
The carburetor was clogged;
The fuel hose and a filter of gasoline are functioning incorrectly.

Cleaning the fuel filter

With insufficient intake of fuel, the chainsaw stalls with gas. The reason may consist in clogged fuel filter and incorrect operation of the carburetor. How to check that the filter is to blame? To do this, partially disassemble the tool body to access the carburetor. Disconnect the fuel hose from it and press the fuel to swing several times. On modern saws, this is a transparent rubber hemisphere, which is pressed before starting the engine.

If gasoline intensively begins to splash out of the hose, then the filter is in order. If fuel goes reluctantly, then you need to change or clean the filter.

It is located inside the gas tank, and in order to get it, you need to remove the plastic protection, then lift the rubber cuff with a flat screwdriver through which the fuel conduction passes. You need to remove it carefully so as not to damage the rubber. Otherwise, it will leak after installing. In some chainsaws, the filter gets through the neck of the gas tank.

At the end of the fuel supply installed in the tank, there is a fuel filter. Usually it is clogged with tarry deposits located in gasoline and oil. The filter is pressed in the hose and removed by simple pulling out. It needs to be washed in hot water with cleaning products or replaced by a new.

The main malfunctions and ways to eliminate them

The operation of the tool should be carried out according to the instructions attached to it. Turn on the start button only after the tension of the circuit is checked, the presence of fuel mixture and oil. Having secured the chainsaw in your hands, you can start work.

If the tool refuses to work, then first of all it is necessary to identify the cause of the malfunction. And the inventory for repairing a chainsaw is suitable for the most common: various screwdrivers, end and wrench keys, hexagons.

The oil lubrication oil leaks

Each owner of the tool will face this problem sooner or later. The cause of such a malfunction is a violation of tightness at the junction of the oil pump and hose from the oil tank.

To eliminate this problem, you will have to almost completely disassemble the chainsaw.

If the hose is damaged, then it is best replaced with a new. You can try to fill it with sealant, having previously degreased and washed.
Oil can flow due to the fact that the oil filter is clogged or broke. It should be checked and cleaned or replaced.

If the chainsaw does not start

If you believe the specialists, then with such a problem, first of all, you just need to open and close the lid on the gas tank. After that, you need to ventilate the combustion chamber, as well as pull out and dry the candles. These actions are enough for the tool to start and work. If the malfunction remains, then the reason should be sought in another.

The fuel supply is affected by the sapun. Therefore, if it clogs, then a vacuum forms in a tank with fuel and the saw does not start. The saapun is repaired very simply. it should be cleaned with a needle.
Stihl 180 chainsaw may not work due to a cylinder breakdown. If there are chips or irregularities on the cylinder, then the reason is in it.
If the tool does not start, a short time holds power or stalls immediately after turning on, then the cause of the breakdown can be in the muffler. It can be clogged with any deposits arising during operation in the process of exhaust.
A saw can start poorly due to the starter malfunction. To see it, remove the lid from the carburetor and twist a special screen located behind the chainsaw drum. If the contact wire has departed from the starter, then it must be attached using a soldering lamp. If the problem lies in the leakage of the oil, then the starter is simply wiped with a cloth.

The engine of the chainsaw works with interruptions

The reason for such a malfunction may be a breakdown of a cylinder.piston group, which is enough simply repair with your own hands.

To extract a cylinder from a tank, four bolts must be unscrewed on its head. Then carefully check the piston on which there should not be any bullying, scratches, chips. If any, then the piston will need to be replaced.

The optimal pressure in the combustion chamber is provided due to the piston and piston rings, which should be tight enough on the piston case. If the piston inserted into the cylinder has a free move when swinging, then this indicates its wear.

This defect can be eliminated through the cylinder boring and installing repair parts. However, the easiest way is the entire set of CPH to simply replace.

Reasons why the chainsaw stalls under load

In this article Remstroisovet construction site.ru will consider the main reasons why the chainsaws may not start or stall at load.

The most common of all are the following reasons:

Why the power of the chainsaw is falling

The same applies to the air filter, it, in the event of this kind of problem, immediately needs to be cleaned. Now at the expense of the spark plugs, it, if it is strongly contaminated, is also cleaned and adjusted if necessary. It is the wrong gap between the candle electrode on the chainsaw can lead to the fact that it will begin to stall, and in general, to work extremely unstable.

Summing up.

Certainly, every thing we bought has its own expiration date and sooner or later it breaks and how it becomes insulting when the degree of its breakdown is so great that it is not subject to repair. But you must admit that quite often we simply negligently relate to the technique (see. about the correct operation and how to cut down the tree to fall in the right direction). And when she stops working, then we are trying to find the possibilities of eliminating breakdowns, while contacting a huge number of services.

But remember that although the technique breaks, but we can extend its “life”. All that is necessary is to simply take care of her, do a run after replacing the parts (how to run the chainsaws read here) and keep its spare parts clean and order. And then, of course, it will last for many years. The use of exclusively high.quality spare parts and “additives” is also important (see. nozzles for chainsaws). Then your technique will work uninterruptedly, and you will simply forget what repair is.
