Frequent malfunctions of the Husqvarna chainsaw 236-240

If it is impossible to start the engine, it is necessary, observing the sequence, to perform the following actions:

The location of the air filter and the spark plug.

  • Check the presence of gasoline in a tank.
  • Replace fuel if it was stored for more than a month.
  • Check the fuel filter. Disconnect the hose from the carburetor and observe the streaming stream. If gasoline flows freely, the fuel filter is not clogged. With insufficient consumption, clean the hole in the tank lid or filter.
  • Clean the air filter. For a control launch, the air filter can be removed.
  • Inspect and clean the muffler from the burner.
  • Check the operability of the starting device. If necessary, repair the starter (replace the pulley, spring or cable).
  • Disassemble and clean the clogged carburetor.
  • Call the tester a high.voltage wire for the lack of a cliff.
  • Measure the gap between the flywheel magnets and the ignition module (should be 0.2 mm).
  • Unscrew the candle and make it examination. Measure the gap between the electrodes with the probe (normal 0.5-0.6 mm). By the appearance of the electrodes, we determine the nature of the malfunction. If the light of the ignition is dry, there is no receipt of the working mixture. The working part flooded with gasoline indicates a poor.quality adjustment of the carburetor or the absence of a spark. To check the presence of a spark, connect the high.voltage tip to the candle, put the skirt on the cylinder radiator and pull the starter cord. In the absence of a discharge between the electrodes, you need to replace the candle. The formation of soot on electrodes indicates the low quality of the fuel mixture. The central and lateral electrodes should be cleaned with sandpaper.
  • There is no compression. The reason is the failure of the piston group. Measure compression. First you need to unscrew the candle. Then insert the pressure gauge into the cylinder hole and move the piston with the starter cord. By pressure in the cylinder, they judge the state of the cylinder-piston group (CPG). It should be at least 8 atm. Low indicators are caused by wear of the cylinder, piston, piston rings.

Why stalls the chainsaw

If the chainsaws start and stall, the reasons can be different. An external inspection should be carried out before attempts to fix the tool.

If the saw stalled during operation, you should check the presence of a mixture of oil with gasoline in the tank. If the fuel mixture is over, the device will not work. In those situations where gasoline still remained, the quality of the tool should be evaluated until the moment of is turned off. The occurrence of extraneous sounds and the subsequent sharp stop should alert.

The formation of soot on electrodes can also cause difficulties in the operation of the tool. Carefully inspect the device, clean if necessary.

When pressing gas

In cases where the chainsaw stalls when you press the gas, you should check the silencer and the fuel filter. A possible cause of problem is a violation of the tightness of the fuel hoses. In some cases, the addition of revolutions helps.

Sometimes checking all the details does not give a result, the tool is suffocating, zooiling when gas is added. If the device stalls when a person presses gas, it is possible to supply fuel in insufficient amount for normal operation. This phenomenon occurs due to clogging of the carburetor or filter.

Damage can occur due to clogging with air filter dust. When you give gas, the device stops working. Do not eliminate the problem yourself, since each model has individual characteristics.

Calling may cause failure or lack of lubrication on the chain of the chainsaw. If the circuit is dry, the channels should be cleaned through which the oil is supplied to the device tire. If the oil proceeds, the presence of cracks, defects on the pipes is noted, you need to treat them with sealant.

Under load

In situations where the device stalls at load, the problem can be with a gas tank or filters. Check the quality of the fuel and change the filter.

Often the saw does not gain momentum due to the fact that the mixture flooded in the gas tank has a low octane number. There is not enough power, sufficient heating does not work, the chainsaw stalls under load.

Often, malfunctions of the component parts lead to the fact that the device stalls under load. You should check for the presence of a sucker hoses, seals, gaskets. If the details are faulty, you can try to fix them or replace them.

In cases where the chainsaw is started and immediately stalls, the fuel is not enough, the device does not heat up. Turn the device

It is important to use a suitable mixture. Different types of fuel are better suited for different models. It is necessary to familiarize yourself with the instructions, recommendations, reviews of people whose device works normally

It is necessary to familiarize yourself with the instructions, recommendations, reviews of people whose device works normally.

At idle

In those situations where the chainsaw stalls at idle speeds, it is necessary to examine the state of the muffler. If the part is polluted, the spent gases are poorly displayed, the engine cannot continue to work, stops.

The saw stalls idle and in cases where the carburetor is incorrectly configured. It is better for beginners to fix the repair to specialists, since there is a chance of incorrect setup, because of which the tool will not be able to work. Tachometer is required to adjust the carburetor.

At high speeds

If the device stalls at high speeds, pay attention to the state of gasoline and air filters, the serviceability of the fuel hoses

Polluted air filter can be washed under warm running water

It is important to thoroughly dry the part before installing it so that the water does not violate the serviceability of the tool

If the liquid stops flowing through the fuel hose, it clogged. You can clean the part or replace with a new.

In cases where the saw stalls at large speeds, but the liquid flows through the hose, and the air filter is clean and working, look for the cause of the breakdown in the fuel filter. Install a new one in its place or clean.

In some cases, the problem is hidden in a gasoline pump. With the wear of the component part, the fuel begins to flow through the walls. If this phenomenon is noted, a new pump should be installed.

When tilted

If the saw does not develop speed when tilted, turns off, stops working, you need to check the fuel level in the tank. If it is not too high, the device is not supplied in an inclined position is not supplied with a sufficient amount of fuel, since the fuel tube is above the mixture level.

Non.standard failures

If a normally working chainsaw engine stalls when tilting the tool on one of the sides, open the gas tank cover and eliminate the freezing of a flexible fuel receiver.

Almost the entire assortment of Chinese chainsaws is more or less copied from popular models of European origin, so structural differences are insignificant. The recommendations given can be used if the Chinese chainsaw refused.

The maintainability of Chinese chainsaw equipment is increased by unifying the repair fund and the interchangeability of many components and parts with the same models.

Basil starts and stalls the reason

If the chainsaw is started and stalls at the first attempts to do the work, then the reason may consist in the appearance of troubles with the brake of the chain or in its jamming due to a lack of lubrication. In this case, the level of oil is determined. If the lubricant volume is sufficient, then the reason may be in the tube that leads it to the lubricant mechanism.

Another reason may be a carburetor breakdown. If he needs only adjustment, it can be done without the help of others in agreement with the annotation. If the carburetor needs to be cleaned or repair, then you can not do without the help of experts.

Another probable cause of this malfunction is the small level of fuel in the tank. In this case, the motorcycle is stalling when tilted, since the remainder of the fuel consistency is in the part of the tank, the back of the place where the absorbing tube is placed.

Why stalls the chainsaw engine when you press the gas

Despite the high performance of chainsaws, sometimes there are such moments when the tool ceases to work normally. In particular, a common situation is the fact that the chainsaw begins to stall when the gas is pressed.

For experimental owners, such a problem is known, but the beginners who have encountered this for the first time, will have to seek help from specialists.

But do not rush, in the material you can find all the important causes of the malfunction, as well as try to eliminate them.

Checking the main chainsaw systems

If the chainsaw after pressing the accelerator has stalled, then there is a breakdown of any element. It is very difficult to determine the cause of such a malfunction immediately, since various factors can contribute to this. The search for the cause should begin with the test measures of the main tools of the tool, from less to greater.

First of all, it is necessary to verify the presence of fuel in the tank. Often, masters during sawing are so carried away that they forget to add fuel to the tank. Even if there is a certain amount of fuel in the tank, and the chainsaw started up and immediately stalled, then the reason for this may be precisely the lack of the mixture as a result of clogging of the fuel channels.

If everything is in order with the fuel, then the reason must be sought in the spark plug. It should be twisted and the contacts should be inspected. If there are no signs of dampness and soot, then you need to check the size of the clearance, which should be 0.5 mm, and after the presence of a spark. If the candle has not been replaced for a long time, then you need to change it, after which to start the tool again.

It is also necessary to check the silencer, since its clog can interfere with the output of exhaust gases, which is reflected in the functioning of the ICE. The muffler is subject to dismantling and wet cleaning of soot. If the above actions do not help correct the problem, then you will need to delve into the situation in more detail, since the cause may be a malfunction of the carburetor or the need to configure it.

The reasons and features of the elimination of malfunctions

Why stalls the chainsaw after launch or during operation, you can only find out after the check is performed. As a result of the audit, you can not only detect the causes of faulty operation of the motor, but also possible breakdown. To find the exact cause, you need to know in what cases the occurrence of a malfunction is observed. Consider such cases, and also find out the features of the elimination of problems.

Stalling when pressing gas

If the engine stalls when gas is added, then the factors may be the reason for this:

  • clogging or incorrect tuning of the carburetor;
  • air filter pollution, through which the motor lacks air to set speed;
  • clogging of the fuel filter, which contributes to the intake of insufficient fuel mixture;
  • Falf of the cylinder-piston group. With an insufficient amount of oil in the fuel mixture, excessive friction of the piston on the cylinder wall occurs, which entails overheating and the formation of bullying.

In case of overheating with a lack of oil in the fuel mixture, you will need to carry out overhaul of the engine, which is one of the most unpleasant consequences. In order to correctly adjust or clean the carburetor, you should give it to a specialist, since the lack of experience in working with small details can lead to damage to the mechanism. Checking the air and fuel filter can be performed with your own hands.

It’s important to know! The fuel filter is subject to replacement every 3 months with the daily operation of the tool.

If the chainsaw does not allow the development of speed when pressing gas, then it is advisable to try to replace the fuel mixture in the tank, especially if it has been in the tool for a long time.

Stalling at load

If the chainsaw begins to stall under load, then the reason for this is, first of all, the wrong settings of the carburetor. If this reason is eliminated, then, in addition to problems with the carburetor, the cause of the instability of the tool during load may be damage and wear of the crankshaft or gaskets or gaskets of the carburetor through which the air leaks in the system occurs in the system.

It’s important to know! Diagnosis with such a malfunction is best done in the service center, where the exact reason will be established.

It is recommended to start searching for a malfunction with checks and gaskets, and after checking the correct setting of the carburetor.

Another reason why the chainsaw is started and immediately stalls at the load is to grind special hoses through which the pulse is transmitted from the crankcase to the fuel pump.

But such hoses are not installed on all models of chainsaws, but only mainly on professional. To eliminate the malfunction, it is recommended to replace this hose. How to do this correctly, is considered in the video:

Stalls at idle

If the chainsaw is poorly started and stalls at idle, then the first reason is the clogging of the muffler. The silencer should be dismantled, then perform it wet cleaning. This is very important, since during dry cleaning, dust can fall into the lungs, which will lead to serious violations of the functioning of the respiratory system.

The second reason that the chainsaw stalls at idle is the wrong tuning of the carburetor. In order for the chainsaw to work at idle, twist the screw called L on the carburetor. If the tool stalls at idle, then the screw should be crank by 0.5 turns clockwise. To accurately adjust the carburetor, it is recommended to use a tachometer, and the settings technology are described in this article (link).

Glakes when tilted

The reason that the chainsaw begins to stall during the inclination is the lack of fuel mixture into the system. The fuel tube is located directly at the bottom of the gas tank, so the tilt of the tool leads to the fact that the tube simply begins to be located above the fuel mixture. Therefore, therefore, when working the tool, it can stall sharply.

For what reasons the chainsaws start and stall?

The use of a chainsaw is facilitated by hard work. But sometimes the chainsaws start and stall, the reason for this can be any. What to do? We must choose: take it to the workshop to specialists or try to repair on your own.

We will try to help the reader understand the reasons for the refusal, methods of eliminating breakdowns and give tips for the operation of chainsaws. In turn, the owner will be useful to familiarize yourself with the factory instructions for operation and the design features of his chainsaw.

This information will help him correctly use and professionally carry out the repair of the tool.

Characteristics of the internal combustion engine of the chainsaw

The main malfunctions of chainsaws are associated with engine failures. As a chain drive, domestic and foreign manufacturers use single.cylinder two.stroke internal combustion engines. The design of the motor is simple. The ignition is ordinary, without installation of capricious electronics. Chainsaw engines reliably work in various climatic conditions. Fuel for the carburetor engine is obtained as a result of mixing gasoline of the AI-92 brand and special oil.

Since the oil pump is not provided in the design, the piston and cylinder are lubricated with a mixture of gasoline with oil. The saw engine develops a power of 2 to 5 kW, and the speed of rotation of the crankshaft reaches 14,000 rpm. With such high speeds and the load, the requirements for the oil are special. Use the oil specified in the instructions. When replacing the oil with the usual engine resource, the tool is sharply reduced.

Remember that refueling tank with gasoline without adding oil is strictly prohibited.

Tools and materials

Scheme of a two.stroke chatefering engine.

The design of the mechanical nodes of the chainsaws is characterized by good reliability and maintainability. Almost all units and details have free access. If you have the necessary equipment, they are easily removed for repair or replacement. To analyze and check the life support systems of the chainsaw engine, you should stock up on such tools and materials:

  • set of locksmithing tools;
  • Candle end key;
  • tester;
  • manometer for measuring compression;
  • probes for measuring clearance;
  • needle;
  • sandpaper paper;
  • fuel mixture (gasoline oil);
  • Vetosh.

Classification of engines malfunctions

Before starting the chainsaw, it is necessary to check the condition of the saw part, season the fuel and oil tanks. After checking, proceed to launch. If there are deviations or failures in the drive, it is necessary to carefully examine the saw engine. As a result of an external inspection, verify the completeness and integrity of all nodes, the absence of mechanical damage, fluxes of gasoline and oil. We indicate the main malfunctions associated with the poor operation of the engine:

  • The engine does not start.
  • Starts up, but soon stalls the chainsaw.
  • It works unstable.
  • Ceases to function at a load.
  • Loses his power.

Search for engine malfunctions is carried out in the following main directions:

Saw mechanisms need constant care, prevention and repairs.

Knowing the principle of action of a two.stroke gasoline engine will help the operator to independently determine the cause of the refusal and quickly restore the gas.speaker work.

Elimination of malfunctions on their own

If it is impossible to start the engine, it is necessary, observing the sequence, to perform the following actions:

The location of the air filter and the spark plug.

  • Check the presence of gasoline in a tank.
  • Replace fuel if it was stored for more than a month.
  • Check the fuel filter. Disconnect the hose from the carburetor and observe the streaming stream. If gasoline flows freely, the fuel filter is not clogged. With insufficient consumption, clean the hole in the tank lid or filter.
  • Clean the air filter. For a control launch, the air filter can be removed.
  • Inspect and clean the muffler from the burner.
  • Check the operability of the starting device. If necessary, repair the starter (replace the pulley, spring or cable).
  • Disassemble and clean the clogged carburetor.
  • Call the tester a high.voltage wire for the lack of a cliff.
  • Measure the gap between the flywheel magnets and the ignition module (should be 0.2 mm).
  • Unscrew the candle and make it examination. Measure the gap between the electrodes with the probe (normal 0.5-0.6 mm). By the appearance of the electrodes, we determine the nature of the malfunction. If the light of the ignition is dry, there is no receipt of the working mixture. The working part flooded with gasoline indicates a poor.quality adjustment of the carburetor or the absence of a spark. To check the presence of a spark, connect the high.voltage tip to the candle, put the skirt on the cylinder radiator and pull the starter cord. In the absence of a discharge between the electrodes, you need to replace the candle. The formation of soot on electrodes indicates the low quality of the fuel mixture. The central and lateral electrodes should be cleaned with sandpaper.
  • There is no compression. The reason is the failure of the piston group. Measure compression. First you need to unscrew the candle. Then insert the pressure gauge into the cylinder hole and move the piston with the starter cord. By pressure in the cylinder, they judge the state of the cylinder-piston group (CPG). It should be at least 8 atm. Low indicators are caused by wear of the cylinder, piston, piston rings.

What to do if the engine stalls after starting?

Fuel interaction scheme and air flow in the carburetor of the chainsaw.

Often we observe a short work of the saw after starting. the chainsaws are almost immediately stalling. This malfunction has characteristic features. The list indicates the probable causes of the malfunction and the methods of eliminating it:

  • Lack or small fuel volume. If the refusal is manifested when sawing in an inclined position, then this indicates the rise of the fuel tube above the fuel level. Check the presence of fuel in the tank. Pour gasoline to the required level.
  • Poor.quality fuel mixture. Prepare fuel in strict accordance with the instructions of the manufacturer of the saw. Completely replace the mixture.
  • Sapun is clogged. Small fuel consumption to the engine. Sapun. respiratory hole in the tank cover. Cleam the blockage with a needle.
  • Poor candle contact with the cap of a high.voltage wire. In this case, the Faore Svek insulator is greatly warmed up. Clean the contact and tightly put the “cradle” on the spark plug.
  • Falf in the spark plug. Replace a new or obviously serviceable.
  • Fluffing muffler blocking (exhaust gas). It is necessary to clean the silencer.
  • The carburetor is not adjusted. To configure the quality of the mixture, the carburetor has 3 screws: “l”. the setting is accurate, “h”. a rough setting of high speeds and “t”. adjustment at idle. Observing the propagation sequence of screws, we achieve higher crankshaft revolutions.
  • The air filter is clogged. The air enters the carburetor in small quantities. we get an enriched mixture. The saw stalls with an increase in the load when sawing hardwood and large diameter trunks. Rinse the filter in warm water and dry.
  • Failure of the piston group. Replace defective parts.

Checking a candle and ignition system

According to the recommendations of manufacturers, the spark plug should be changed annually, regardless of the intensity of the operation of the tool. Non.compliance with these tips leads to a completely natural result: malfunctions at idle, subsequent refusal.

Typical defects in the ignition system are as follows:

  • The candle was flooded with fuel at the time of launch. It is necessary to extract it from the nest, dry, if possible to blow out with compressed air. Drain the remains of fuel through the installation hole, blow out with compressed air. Then install the candle, connect the high.voltage wire, start.
  • Lack of spark on the electrodes of the candle. It is necessary to disconnect the high.voltage wire and check the presence of a spark on it. If the spark is normal, check the connection, the detected defects eliminate. The absence of a spark on a high.voltage wire indicates a malfunction of the ignition unit. This device is not subject to repair, it is necessary to change it for a new.
  • The gap between the electrodes of the candle is broken. This parameter for various types of devices can be in the range from 0.2 to 0.5 mm. Check and adjustment must be performed using a special probe or caliper. The required value can be found in the instrument operation instructions.
  • By the appearance of the candle, you can determine the direction of the search. If the candle after several attempts to start the engine is dry, then gasoline does not enter the cylinder. It is necessary to check the fuel supply system and carburetor.
  • The presence of black soot on the electrodes of a soot or a blackflow indicates the improper adjustment of the carburetor or clogging an air filter. Perhaps low.quality fuel with large m oil is used. With normal operation of the ignition system, the electrodes have uniform gray color and brown plaque on insulators.

What to do if the chainsaw stalls at idle

The chainsaw stalls at idle: many owners of this tool are faced with such inconsistent. On their own device, a fairly light tool drank. But there are times when it fails. The main problem when eliminating a malfunction is to determine the correct cause of emergency work. After establishing the reason, eliminating the defect is usually quite simple.

Probable reasons for the refusal

The power unit of all chainsaws is a single.cylinder internal combustion engine. Devices of this type are characterized by such malfunctions as a violation inside the cylinder compression, a change in the ratio of the fuel mixture, incorrect ignition, low-quality fuel and lubricants. The main problems in the operation of the power unit are the following:

  • The engine works steadily at minimum speeds, but with an increase in revolutions stalls;
  • Starting is normal, and idle turns are unstable, stall quickly;
  • does not start.

Electronic ignition diagram of the chainsaw.

High.standard work on idle can be caused by various reasons. They can be divided into several positions:

  • reduced capacity of filters (gasoline and air);
  • Ignorary I ignition systems:
  • The settings of the carburetor have spontaneously changed;
  • malfunction of the elements of the gas pipeline;
  • exhaust channels, muffler are clogged;
  • Defects of the piston, cylinder, valves.

Repair should be started with an external inspection and checking the presence of fuel in the tank.

Checking and repair of filters

The engine can work with interruptions or stall with insufficient fuel or air. Reasons. clogging of air or fuel filter. To check the fuel filter, it is necessary to remove the gas pipeline hose from the carburetor fitting and directed into any container. Then press the fuel pumping several times. If the fuel is pumped normally, clearly expressed doses, without dirt, then the fuel filter is working. If the stream is weak or fuel does not pump at all. the filter must be replaced or if possible to clean.

Read when the chainsaw is noted when the chain is spinning

Fuel filter clogging with sawdust is one of the reasons for the gas station breakdown.

The device must be removed from the fuel tank (preliminary draining all the fuel from it). In most models, the fuel filter can be pulled off from the wire through the neck. If the design of the filter is collapsible and allows cleaning, you need to disassemble and rinse in accordance with the recommendations of the manufacturer. In another case, change for a new filter.

Similar problems can occur when clogging an air filter with dust, sawdust, and dirt. With an insufficient amount of air, the fuel mixture will be enriched, the process of combustion of fuel is difficult.

To check, remove the filter. When working, you need to take precautions so that the dust does not get into the carburetor. The device needs to be cleaned and washed in warm water with the addition of detergent. After drying, if possible, blow out low pressure with compressed air, set in place. If the chainsaw works normally, then the reason is eliminated, if not, you need to look for further.

With the constant operation of the tool, the replacement of filters of the fuel and air systems is recommended after 3 months.

Carburetor check and repair

If the check of the ignition system, fuel filters, muffler did not give tangible results, the tool still does not want to work normally at minimum speeds, you need to check the carburetor.

To adjust the operating modes on the device housing, there are three screws designed to install the minimum rotation speed, maximum revolutions and idle speeds.

Power system: improper fuel mixture

Two-stroke engines are designed to work from a mixture of gasoline with butter, which is necessary to lubricate the cylinder-piston group. The lack of oil will quickly disable the tool and lead it to major repairs.

In gas tools of different manufacturers, the ratio of oil to gasoline is 1:40 or 1:50. This proportion cannot be violated in any case. If the oils are poured more than the necessary, this will lead to the shift of the compression rings of the piston. They will tightly fly in their grooves, and the motor will lose compression and power.

The exception is only the mode of running the tool. In this case, the mixture is made 1:25 and it is used for a short time, with a minimum load.

Signs of an excess of oil in gasoline are as follows: the chainsaw stalls, abundantly smokes, does not develop power.

chainsaw, started, immediately, stalls

The chainsaw engine turns off after reaching the maximum speed mode

The power unit stalls at high speeds due to the inconsistency of the stated requirements of the working characteristics of the electronic unit. The refusal is more characteristic of budget chainsaws of Chinese.

  • Lack of fuel mixture in a float chamber due to jamming of the valve;
  • clogging of the fuel filter or the fuel tank of the fuel tank.

The power unit also stalls at large speeds due to the contaminated air intake filter. The same signs are characteristic of a situation where a chainsaw started up in standard mode and stalled at the warming stage.

The saw stops after the release of “gas”,

Here you need to configure the carburetor and check if there is a powerful air suction.

The most common cases of chainsaw failures that we have already seen. Only Nayedatsya remains that your saw will serve without failures. But even such reliable models such as Shtil and Partner can sometimes fail.

Why stalls the chainsaw? Reasons and their elimination

What to do if the chainsaw was stalled? Many owners of the chainsaws know the weakest places of their tool, but the situation may arise when the reason could not be found immediately.This manual will also be useful to those who have recently acquired a chainsaw.

ATTENTION! If you have not found your reason in the list of below, you can ask your question in the Комментарии и мнения владельцев. So, the chainsaw was stalled. There may be quite a lot of reasons, because at least the drink and not the Formula 1 Bolid, it is a technical device.

Your Chainsaw Stalls? You Can Fix It, Here’s How

Here the main condition for successful repair will be an accurate diagnosis of a malfunction.

Do not immediately start disassembling the chainsaw, first you need to check the simplest possible causes of the malfunction.

Consider the approximate steps of checking the possible cause of the malfunction.

(This is the second edition of this article, in which I will try to describe all possible reasons as detailedly as possible.)

If you do not start a chainsaw, then more details here:

Identification of malfunctions

If the chainsaw stalls for no apparent reason and it is not possible to even establish approximately possible problems, then it is worth passing in series for all possible reasons. There are certainly typical, standard malfunctions of which we will talk about below, but so far we are walking step by step!

one.Check the fuel mixture.

Firstly, it must be prepared according to the recommendations of the manufacturer and using high.quality components. Secondly, produce the tank completely or drain the fuel mixture before prolonged downtime or conservation between seasons. Read more about the fuel here:

2.Clean the air filter or change it.

Polluted air filter does not allow the supply of air to the volume to which the normal operation of the chainsaw is designed. That is, if the carburetor, which mixes the air and the fuel mixture was adjusted with one amount of the accumulated air, then when contaminating the air filter, the amount of air decreases, and the settings remain the same and as a result we get an enriched working mixture.

3.Check the candle

There may also be several subparagraphs. The first step should be unscrewed the chainsaw candle and check if it flooded during attempts to launch. This occurs especially often when the chainsaw is launched by inexperienced users who do not comply with the sequence of launching the saw to the cold.

In this case, you need to dry the candle or screw the new one and repeat the attempt according to the instructions. The tip of the candle can fail. You can check this by twisting the candle and putting it into the tip put on the block and pull the launch cord a couple of times.

If there is a spark, then both the candle and other electricians are in order.

Another step in checking the candle is to check the gap on the candle and for the presence of soot. See the clearance in the recommendations of the manufacturer. As a rule, this is from 0.5 to 0.65 millimeters.The soot from the candle is cleaned with fine.grained sandpaper or metal brush. Read more about candles here:

Diagnosis of a chainsaw engine by a candle

four.Check the fuel filter

As with an air filter, the situation with the fuel filter leads to a change in the composition of the working mixture. Only if the air is polluted, then the mixture becomes richer, and with contamination of the fuel, on the contrary, the more poor.

The engine of the chainsaw will not work with insufficient fuel in the working mixture. In addition, with a clogged fuel filter, uniform fuel supply to the carburetor is disturbed and further into the combustion chamber.

This is especially noticeable when the chainsaw stalls when you press the gas.

Capun is a check valve, which is located in the gas tank of the chainsaw and prevents the occurrence of a vacuum in the tank. If it is clogged, then instead of the used fuel mixture does not enter the air and the fuel pump cannot cope with the supply of fuel.

Often there is a situation when a primer (pump for preliminary pumping of fuel) fuel was pumped into a carburetor-chainsaw started. After the fuel supply in the carburetor is spent, and in view of the clogging of the saapun, the fuel is not supplied, the gas stalls stalls.

6.Carburetor check

In 50% of cases, if not more than the reason that the chainsaw is stalling is an incorrectly configured or failed carburetor.

The chainsaws are stalling or not starting up for gas: the main reasons and ways to eliminate them are Sibnovstroy

Not only the category of household chainsaws, but the more reliable instruments of the Profi class are not insured from breakdowns, periodically fail and do not start up.

This is due to the fact that the production resource of 2-stroke engines, which most often equip such units, also has its own certain limit, the duration of which depends not only on the wear of parts and structures, but also on the features of operation, the quality of the poured fuel and oil, compliance with all requirements for storage and operation of the parting, which users themselves often violate.

One of the most unpleasant situations that can be observed all the time and is, it is when the saw either does not start at all, or starts up and immediately stalls, putting a lot of production tasks under the threat of non.fulfillment. Let’s figure out how to recognize specific breakdowns and what needs to be done so that the unit is functioning again.

The chainsaw does not start. the main reasons

Being a rather complicated and multicomponent device, chainsaws can fail for a number of reasons arising in its individual working bodies.All their diversity can be reduced to the following:

  • problems with filtration systems of the device, in particular, with air and fuel;
  • to reduced compression;
  • breakdowns of the carburetor or its unhealthy;
  • possible problems with spark plugs;
  • when the source of the problem lies in the ignition coil or the gap between it and the flywheel.

Why the chainsaw stalls immediately after starting?

The situation when the chainsaw stalls when you press gas, which is quite common, which is a reliable signal that there are quite serious problems.

Can serve this:

  • mismatch of the combustible mixture by the necessary requirements;
  • clogging of filtration components of the chainsaw;
  • reduced compression;
  • The carburetor is incorrectly adjusted;
  • incorrect operation of the ignition system.

The most banal of all listed is the first situation when it is not possible to start a gasoline unit, since its fuel tank is empty or fuel is not enough to start starting.

Another moment is the wrong proportions of the combustible mixture, low.quality gasoline with a low octane number, or an inappropriate oil chainsaw model.

If everything is clear and verified here, it is worth starting to work out other causal relationships.

If the gasoline filter is contaminated, the supply of fuel can not only be complicated, but completely stopped, which violates the normal launch of the saw or even does not allow it at all.

In this connection, the gasoline does not start or stalls at idle?

The situation when the benzo tool starts and stalls can be observed in the following cases:

The bolt L, which can try to turn a little, which in most cases works instantly is responsible for idle speeds in the carburetor. It can also often lead to such consequences during the manufacture of a combustible mixture, which usually entails many related problems.

Why does a gas tank stall when you give gas?

There may be even more reasons for this than in previous cases. Consider the main of them.

  • Low quality fuel or oil, as well as the wrong calculation of the volumetric parts of the mixture that the user’s guide requires;
  • Unforeseen bay with fuel spark plug after launch at idle. To resume the operation of the excess fuel, they are drained, the candle is removed from the device and dried. Only after that can the start of the unit can initiate again;
  • Also, a chainsaw is started normally, but when adding gas stalls because the spark may be a gap. This usually happens when a weak conjugation between the wire and the candle tip or there are significant defects of incendiary elements.
  • There is not enough fuel for the normal functioning of the chainsaw or its insufficient receipt (clogging with dust particles of the aerofilter or saopon).
  • Muffler “over” pollutants and requires urgent cleaning.
  • Problems in the cylinder.piston system.
  • Lubrication system problem. It may simply not be enough or the oil filter and conductive tubes can be clogged with particles of garbage. They wear out very much, so it is worth it every time before you start working with a gas tools to check it for the integrity of the tubes and compounds that supply grease.

Why the chainsaw stalls when loading?

Chainsaws equipped with high.speed engines are often refused to work with an increase in the load. If the chainsaw works normally at idle, but stalls under load, this indicates a number of possible malfunctions, such as:

  • The filter was clogged for fuel;
  • gas tank defects or clogging;
  • The quality of the combustible mixture used does not meet the requirements of the unit.
chainsaw, started, immediately, stalls

If the case is in a filter or a gas tank, we recommend that they replace them with new ones in order to protect yourself from possible problem situations in the future.

Even if this did not help to establish the situation, and the gas technician continues to suddenly turn off before the start of fruitful labor, it is necessary to prepare a new fuel mixture using only high.quality gasoline with a high octane number.

The proportions of oil and gasoline must be strictly designed so that the motor can generate the required power even with fairly large loads.

What if the chainsaw is gaining momentum and stalls?

This situation is very similar to the previous one, the only difference is that there the chainsaw does not show high speeds at all, but here it initially gives them out, but does not hold them. Most often, the chainsaw stalls when heated due to the clogging of the filtration parts of the saw, as well as the malfunctions of the pump for fuel.

The air filter is periodically washed and dried before re.installation, and the fuel supply hoses should be constantly checked for tightness and, if necessary, replace it with new.

Each detail has an expiration date, so you should not be surprised that the gasoline pump will stop holding fuel in itself and begins to ooze, which should also be taken into account while searching for non.proceeds of such technology.

The engine stalls when switching to idle mode

The malfunction is manifested by unstable work in working mode and stalls at idle. The reason for this phenomenon is most likely in the air suction between the carburetor and the suction pipe of the cylinder. The refusal is eliminated by a suspension of screw fasteners.

Usually, when they are looking for the reason why the chainsaws stall, the first thing they look at the spark on the spark plug. Often, the owners of saw simply forget to change the candles in time. But it depends on her how stable and economically the tool will work. If the chainsaw is used intensively, then the candle needs to be changed once a season. If the candle defects are not detected, there is confidence in high.quality contact between the high.voltage wire and the candle cap, but there is no spark, then the problem is not allowed in the electronic ignition unit. For a person without the formation of an electrician, it is difficult to understand anything there. This knot is easier to change in its entirety.

There is a spark, a candle is wet. how to solve the problem?

Wet candle indicates a violation of the proportion in the preparation of the fuel mixture. In this state, the detail at first is still able to form a spark, but gradually this property of a candle is lost. In addition to the improper ratio of oil and fuel, there are a number of reasons why the element floods.

  • strong clobs of the air filter;
  • malfunctions in the carburetor settings;
  • malfunctions in the operation of the standard ignition system;
  • incorrect sequence of actions when starting a cold motor;
  • Poor quality of gasoline.

In the first case, the repair of the chainsaw is carried out by thorough cleaning or complete replacement of the air filter of the tool.

If when working, the tool began to consume a large amount of fuel, and engine speeds began to constantly “swim”, decreasing and age every 5-10 seconds, then the owner of the chainsaw should configure the carburetor.

chainsaw, started, immediately, stalls

With the repair of the standard ignition system, everything is a little more complicated. To do this, check the entire electrical wiring and make measurements of the gap between the high.voltage wire and the tip of the candle. If necessary, you also need to clean the ignition system from blockages.

If none of these malfunctions were found, then it will be necessary to study the instructions. Perhaps the operator performs the tool in the wrong sequence.

If none of the above helped, then the cause of the breakdown is a poor.quality fuel. In this case, you need to drain the remaining gasoline and pour new fuel with a higher octane number.
