Husqvarna does not start a spark eat. Husqvarna 236 chainsaw is stalling when you press the gas

12th January 2023

Husqvarna chainsaw is not launched. Why the chainsaw is not started and there is no spark. the reasons and ways to eliminate

A key role in any chainsaw is played by a carburetor power unit of a two.stroke type. Its power directly depends on the selected model and purpose. The second important mechanical node in the device is considered the saw part, which consists of a tire, a cutting chain and a chain wheel. Data parameters of the components may vary.

With lubricating mixing, it is carried out using special oil, which is poured into a specialized tank, it is located on a manual block. Separately, it should be distinguished that the volumes of the oil tank and fuel are calculated in such a way that their contents, as a rule, ends at the same time.

Fault options and elimination methods

Regardless of the brand of the chainsaw. Champion, Husqvarna 236 or Patriot, the reasons for poor work are identical. Options why the stihl chainsaw is not started, the mass is the following.

The chainsaw is poorly started on the cold

If the saw is poorly started on the cold, it means that it does not have compression. This is due to abrasion of rings due to long-term operation. It turns out when the user is trying to start Champion 137 in a cold state, compression for this manipulation will not be enough.

In this case, it is not recommended to systematically pull the handle. In the end, the unit will nevertheless start, but at the same time, other mechanical nodes may break off it. In this situation, you need to replace the erased rings with new.

The chainsaw is not started on hot

Here the reasons lies in the filing of the engine and get wet of the candles. Here’s what to do in such a situation:

rearrange the air damper in the middle position;
well make the components of the parts;
start the device for 10 seconds;
transfer into the mode of operation at idle;
on a chainsaw caliber or other model completely open the damper.

Next, just start the motor at idle with pulling the handle. If the engine does not overheat, it will easily start.

In the event that this option of eliminating the malfunction did not help, then the motor has already managed to cool strongly. Make a fiction of half.gas according to the recommendations from the instructions and repeat the operation.

You should also try to scroll through the cold screw in the direction of movement of the clockwise. The higher the speed of the rotation in the equipment, the easier it is to start it. You should know that the chain at idle should remain in a stationary position.

The chainsaw is poorly started and stall immediately

In this situation, the reason is the filling of suppositories with gasoline at the moment when the user tried to turn on the unit. A small volume of fuel accumulates under the candle electrodes, which is why there is no spark in the equipment.

Removing a candle and its thorough drying will help to solve the problem. In addition to these actions, you can additionally fragment. But this manipulation should be carried out exclusively using a gas burner. In another case, a small cargo in the field of electrodes may form. After complete drying of the candles, you need to drain the excess fuel and leave to dry the equipment itself.

Chinese saw does not start

It should be noted right away that Chinese devices do not have a distinctive features from other analogues. They are also reliable and productive, moreover, they cost less. The only thing that is necessary for this device is necessary is to use only branded oil and fuel.

Most units do not work well on the fuel of domestic manufacturers, gasoline clogs channels and, as a result, fuel does not enter the motor. Use fuel either of high quality or from the manufacturer of the saw itself.

Why is the new saw not working

New equipment should not have problems with the wear of functioning mechanical parts, since the model came out only from the conveyor. Such untidiness may occur in the case of the acquisition of demonstration technology, which was more than once used to advertise the company. The cause may also be improper operation of the unit, which does not comply with the recommendations from the instructions.

First of all, you should check whether all parts and components of the elements are installed in their places. Still, for example, Husqvarna will not start if the fuel mixture prepared without taking into account the necessary proportions was poured into it.

But if all the recommendations are followed, each part is carefully recorded in its place and the equipment was not purchased from the stand, probably the buyer came across a defective device.

The tank is not enough fuel or it is of low quality

This is one of the most common reasons. Users of gasoline technology, in order to save, often use budget fuel. At first, the unit will regularly perform its work, but the problem will certainly arise after several months of operation.

There is no spark in the chainsaw, replacement of the ignition coil/No Spark in the Chainsaw, Ignition Coil Replaceement

In this video, a breakdown of the ignition coil is considered, its replacement and launch of the chainsaw. And also watch mine.

Insufficient intake of the fuel mixture from the carburetor to the cylinder or a violation of the correct ratio between fuel and air mixed in the carburetor can occur for several reasons: due to the air filter, unexplored carburetor, clogging its channels or mesh-filter.

As a rule, the repair of the chainsaws is not complete without cleaning the air filter, since it is polluted quite quickly. When this happens, the flow of air into the carburetor decreases, the fuel mixture at the exit from it is too enriched, which violates the normal operation of the engine. Removing a dirty filter for cleaning must be carefully so that the dirt from it does not get into the carburetor. The filter should be cleaned or washed in water with some detergent, dried and installed back.

Carburetor’s resolution is eliminated by its adjustment. This is usually done using three screws. maximum and minimum revolutions and a blank screw. Adjustment should be carried out in strict accordance with the instructions, the non.compliance of which can lead to engine breakdown. Some saw manufacturers leave only one adjusting screw (idle turnover).

If the adjustment of the carburetor did not help, you need to clean its channels and a filter net, and at the same time check the integrity of the membrane. Carburetor. One of the most complex devices of the chainsaw, so you need to proceed with its disassembly and cleaning with a complete understanding of the responsibility of this operation. It consists of many small details that have a feature to slip out of their places and irrevocably lost, so that, having dismantled this capricious device, you can not collect it.

Below is a diagram of another carburetor of a chainsaw.

If there is no experience and confidence in their own abilities, it is better to entrust the carburetor of the chainsaw carburetor to a service center specialist. Sometimes for high.quality cleaning the carburetor, ultrasound is used.

Muffler. Often the cause of the engine malfunction, especially when the engine works normally at low speeds and stalls under load, becomes clogging the combustion products of the sparkle of the silencer, which prevents the normal exhaust. Repair in this case consists in removing the silencer, disassembly (if it is piercing) and its wet cleaning from the soil using detergents.

One of the reasons why the muffler might clog. This is the use of a fuel mixture with an excess amount of oil (the amount of oil is more than the manufacturer recommends), and the use of either not designed for two.stroke oil or low.quality oil engines.

The cylinder-piston group. The malfunctions of the cylinder-piston group belong to the most serious. This is the wear of the cylinder and the piston, scratches and bully on their surface, wear or marketing in the grooves of piston rings, wear of the crankshaft bearings. Most of these malfunctions leads to a drop in pressure in the cylinder and, as a result, to the inability to start the engine, or its inability to give full power. There are several ways to assess the state of the cylinder-piston group (CPG).

You can remove the muffler and look in the opening window in which part of the side surface of the cylinder is visible. Despite the limited review, the general idea of the state of the CPG in this way can still be obtained.

It is useful to measure the compression in the engine, which is quite informative in relation to the state of the parts of the CPG. The operation is carried out using a compressometer installed in the candle hole.

The crankshaft is turned using an electric motor (drill) with a flexible shaft or manually starter, while controlling the pressure according to the pressure gauge. The latter in the efficient chainsaw should be at least 8-9 atm (0.8-0.9 MPa). With its decrease, the engine power falls. At a pressure of five atm, the engine may work, but only at idle.

You can accurately evaluate the state of the CPH only by completely dismantling the engine. disconnecting the crankcase from the cylinder and extracting the piston. If the latter has bullying, chips or deep scratches, it needs to be changed. In relation to the cylinder, when developing or damaged the surface, it is possible to waste it under the repair size.

The engine will not start;
starts, but stalls;
It works unstable;
does not develop power, t.e. It works normally at idle, but stalls under load.

Why not start and what to do

Among the malfunctions of the Husqvarna chainsaw, the engine is highlighted. The motor is either completely impossible to start, or it starts poorly.

When asked why the chainsaw is not started, there is no unequivocal answer. The main assembly unit of the tool is the engine. The stability of the work is influenced by the following conditions:

For each factor, his working knot is responsible:

for the combustible mixture. carburetor;
for the air. the cleaning system, in particular, an air filter;
for a spark. ignition and candle mechanism;
Lubricant. lubricant and gasoline.

The common reason that the chainsaws are not starting is referring to the non.compliance of the launch algorithm. The motor unit should be launched only after the full assembly of all parts:

The brake of the chain is always turned on. In order not to lose control of the tool, you can not start in the air.

The launch of the motor in the cold state is carried out as follows:

Put the tool on the ground, step on the back handle with the right foot, the left hand is located on the front handle.
The saw is in a stable state, the chain does not apply to the soil.
Take the starter handle with the right hand, pull the cord, while it is not twisted around the hand.
As soon as the first outbreak occurs, they return the lever of the air damper to the initial position, opening it, and repeat the start.
Gas and release. The lock is turned off.
They transfer the engine to idle speed due to the rapid shutdown of the gas limiter.

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

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

If the incendiary system is faulty, the candle is inspected and checked for the presence of spark on the electrodes. If it is wet (gasoline floods the candle), and the spark is not detected, the part is turned, dried or changed. If it is dry, the spark is present, then the problems in fuel equipment are clogging, depressurization of the gas intake.

Magneto malfunctions are also confirmed by a weak spark. Despite the ignition, there may be no outbreak in the cylinder, while a candle turned out of the cylinder, wet. The method of elimination is the purge of the cylinder with open carburetor shutters.

The electrodes of the system are covered with soot or oiled. This is eliminated using a metal brush. The candle is washed, cleaned, giving gas to evaporate.

Violation of the gap between the side and central electrodes leads to a poor start. Normal interval indicator-0.6-0.7 mm. It is adjusted by the bending method.

In case of damage to the ceramic insulator surrounding the central candle, or live cores of wires, the wires are replaced.

If it starts and stalls

Husqvarna chainsaw starts and stalls when you press the gas. This leads the jacket of the carburetor jacket and the contamination of the fuel tank filter. The defect is eliminated as follows:

The next reason why the chainsaws stall is pollution of the muffler with exhaust resins. The issue is solved by cleaning.

Distance of piston rings affects the work of the cylinder.piston group. In the presence of a backlash during the audit, the details are replaced.

When starting the engine, the unit may also stall:

With increased dryness, the channels supplying oil are cleaned, the elements of the connection of the fittings with the tubes are examined;
When oil leaks in the connecting points or the presence of cracks on the tubes are sealed with sealant.
If the piston rings in the grooves are buried;
with the wear and elasticity of the rubber sealing of the crankcase;
leakage of the cylinder connection to the carder;
due to improper installation of the ignition force angle;
as a result of contamination of the ribs of the cylinder and the fan lattress;
with strong load immediately after buying a new engine.

How to set up a chainsaw

In the process of repairing the Husqvarna chainsaws with their own hands, they reveal some malfunctions that appeared as a result of incorrect ignition adjustments and carburetor settings.

The mechanism is responsible for the power of the motor and is set up for operation, taking into account the necessary conditions:

By default for productive work, the factory settings of the Husqvarna chainsaw carburetor are installed during the tests.

The device has 3 tuned areas:

How To Fix A Chainsaw Coil Spark Issue

To configure the chainsaw, after the running.in, they adjust the carburetor: first they are engaged in a “L”, then the screws of XX “T” and “X”. With the rotation of “l” and “x” clockwise the quality of the working mixture “air. fuel” worsens, when rotation against. is enriched. Rotation of the screw “t” clockwise increases the speed of xx.

Repair of the carburetor is carried out by a specialist.

Tips for eliminating faults

Fuel transfusion and filling of the chainsaw candles can be single and random. For example, the “perry” with a cap of the pump (primer): the engine did not start right away, the operator presses his finger on the cap again and again, tries to start, pumps up again.

In this case, the reason is not at all in the carburetor. You need to turn out the candle and blow the combustion chamber, pulling the starter cord several times, as when starting. They wipe the candle, dried on the flame of a gas burner or burner, or use another. Check the spark, put the candle in place. Try to start first without suction.

If you do not start after 3-4 jerks, press the pump cap 2-3 times. Try again. That is, after overflow, it is first better not to pump fuel, but to pump it on an increase in. Until the engine starts.

NO SPARK CHAINSAW ? EASY FIX !

Candles sometimes require their maintenance and care.

Inside, around the insulator, there should not be a carbon or dirt categorically.
Contact of the electrode and records from the body of the candle is cleaned with sandpaper “nulevka”. Neatly, without twisting the end of the electrode.
You need to know the recommended candle clearance indicated in the instructions for each chainsaw model (from 0.5 to 0.65 mm or more).
For accurate adjustment of the candle clearance, special probes are used. a fan set of plates of different calibrated thicknesses that are folded in the handle, like a folding knife. Sold in auto tools and spare parts.
When working in winter and store a chainsaw is better at low temperature. When removing from heat to the frost from a sharp temperature difference, condensate can form everywhere, including in the ignition system, which is harmful.

One of the reasons for the lack of a spark in the chainsaw is told in the next video, where they also say how to fix the breakdown:

Modern ignition systems of chainsaws are quite compact and reliable. It is only necessary to protect them from direct moisture, strokes, exposure to extreme temperatures. And then there will be no problems with the lack of a spark during the launch. Also, obviously serviceable 1-2 spare candles will not be superfluous.

Question: With a chainsaw Husqvarna 137, a standard problem happened (pulse channel sealing). After replacing the saw, an unknown malfunction appeared.

It starts well, it works stably at idle, but after 5 minutes of work, power falls, the saw begins to work at increased speeds and zabloks. I suppose that the problem is to set up a carburetor, but I don’t know what exactly.

Answer: Perhaps the air leaks through the same impulsive. In principle, after replacement, it is recommended to adjust the carburetor.

You should not regulate it yourself, for this you need a manometer, if you impoverish the mixture, then throw out a piston. See the mounting of the carburetor when heating the saw, somewhere the air begins to suck.

Question: I have a question about the chainsaw of Husqvarna 137. At first (when the problems began), the saw worked at idle speed, and at high speeds for a few seconds she worked and dropped the speed to stop the engine, then it was impossible to stop at medium speeds and it was impossible to start up until he unscrewed the candle and screwed it back.

He took off the carburetor, disassembled, washed-sustained-results 0.

I disassembled the saw completely found that the rubber tube was rubbed, which connects the carburetor and the sleeve (small), the group is normal, the gap in the ring is also, there is a backlash in bearings (more noticeable from the ignition side since 1 petal is broken off, I think from this and play) gathered, start only on a leak, it works for 3-5 seconds and stalls.

Opening the damper, it becomes immediately, after several attempts of the candle and the piston become wet. What could be the reason? there may be an air leak from under the seals? Pour the carburetor?

Answer: you need to disassemble the chainsaw. The rubber tube connects the cavity under the piston with the diaphragm of the gasoline pump in the carburetor. If the tube is torn, then the dirt will suck under the piston, and the pump will not work in the carburetor.

I hope the phone was replaced. There was a disassembly of the carburetor, whether the screws of idle and the quality of the mixture were twisted? If the seals are sucking, then there will be a depletion of the mixture, and the candle should not fill the candle in theory. The fact that the petal on the impeller is broken is extremely bad. The imbalance at 11,000 rpm will be terrible, the bearing will be spread decently.

Question: There is a gasoline saw Husqvarna 137. I don’t remember how much the saw for years. I saw a lot. Recently, she began to lose in power, and a few days ago she died out and stopped starting.

What was done: replaced the candle with a new Bosch. The result is zero. Remove the fuel filter. zero. Put it back. Dismantled. assembled a carburetor. (The screws never touched). The membranes are intact. A set of membranes will come soon, we want to replace just in case. Changed fuel.

The chainsaw is not started on hot

In cases where the chainsaws do not start hot, you need to conduct a visual inspection of all the main nodes of the chainsaw. Inspection should start with the spark plug. Check the spark, inspect the surface of the candle electrode, these actions will help establish the direction in which you should look for the problem.

Malfunctions in the ignition system

If, when examining a candle, it is found that it is wet and sparking on the contacts does not occur, this means that the problem should be sought in the ignition system, inspect the coil, check the gap between the flywheel and contacts of the coil. You can also check how tightly the cap of the high.voltage wire sits on the candle, and the candle itself. Try to replace it with a new.

Problems in the fuel system

If during the examination it was found that there is a spark, and the candle is dry, it means that the problems are in the fuel system. Its check should start with the fuel filter. Next, you need to inspect the fuel hose and its fastening to the carburetor, pay attention to, on the fuel leaks from the carburetor and the presence of gasoline in the air filter housing. It is advisable to start removing the carburetor only if the visual inspection did not allow determining the cause of the breakdown.

A characteristic feature of the problem in the fuel system is an excessive amount of fuel in the engine cylinder. As a rule, the signs of this are an overly wet spark plug and the presence of a spark on the contacts of the candle. In this situation, it is necessary to turn the chainsaw so that the candle hole is directed to the bottom. If gasoline will flow from the cylinder, then the reason that the chainsaw does not start, it is transferring fuel to the engine.

“Floods” with fuel, sometimes due to improper adjustment of the carburetor, or its malfunction.

The process of adjusting the carburetor can be found on the example of the Champion 254 saw, watching the video instructions.

Summing up

Undoubtedly, the chainsaws occupy an important place in the daily life of each of us, especially when there is a need to carry out certain work in garden areas. The rating of chainsaws by quality watch here.

And if you are going to buy a chainsaw for yourself, then you will make the right choice and will not regret it for a second.

First of all, what I would like to draw your attention to, since this is that this kind of tool will perfectly serve you for various kinds of manipulations associated with wood sawing, harvesting of firewood and processing of the garden.

Husqvarna 137 chainsaw malfunctions are not so rare, but the specificity of its device allows you to do it independently with most of them! Find out how to choose a chainsaw video here.

What to do if the chain saw does not start

Good afternoon, dear readers and subscribers of my blog! At some wrong moment you can find that your chainsaw does not start. But do not rush to immediately take the tool for repair, perhaps you yourself can eliminate this breakdown. I will tell you what to do in cases where the chainsaw does not begin, and how to find the right solution to this problem.

How the mechanism works

Almost all tools and foreign tools are organized in the same way (Husqvarna, Makita, Shtil, Partner 350) and Chinese chainsaws, as well as domestic (friendship, Ural). Therefore, finding the reason why the device does not start and does not stop is not very difficult.

There are four elements in which problems may arise:

Fuel for which the carburetor is responsible;
Lubrication;
The air that enters the air filter;
Spark, the quality of which depends on the ignition unit.

All of them depend on each other and interact with each other. If any element works incorrectly, the saw stops working.

To begin with, all the tools are in different ways-hot and cold. Two frequently used mechanisms are responsible for this process.

Do not forget to see what is written in the user guide. It says that when you turn on, you need to make sure that the emergency stop brake is recorded. But starting a saw with a brake is much more difficult, so sometimes it is better not to turn on the brake.

As you can see from the leadership, there is a fuel tank and engine inside the case, and the saw section (tire with a chain), pen and starter outside.

First we need to find out exactly how the tool does not start. For example, the saw begins, but immediately catches the eye or loses the power of work, the quality cuts.

Possible interruptions arise due to problems in the engine. But I would not recommend immediately making it out. It is better to look for a problem by the simplest option.

Amateur and professional chainsaws are difficult to devices. Motor resources of their two.stroke engines, components and assemblies have its restrictions. For this reason, quite reliable and expensive tools along with cheap Chinese units periodically fail and refuse to start. The situation when the chainsaw does not start or stalls is not very pleasant and sometimes puts the user at a dead end. How to determine and eliminate the malfunction, returning the tool to the tool.

How to make sure that there really is no spark

To make sure there is a spark on the chainsaw or not, you need to perform a simple procedure:

The upper cover on the case is removed.
Gently, with a capture under the very bottom, so as not to tear off the candle wire, a cap is removed from the candle.
The 19th end key included in the kit, the candle is unscrewed counterclockwise.
The cap is put on the place, on the candle.
The thread or nut of the candle is “closed to the mass”, that is, pressed to the metal head of the cylinder. To provide confident contact, the candle is pressed to the cylinder with electric pliers, a screwdriver with insulated handles or a hand in dielectric gloves. This should not be done with a bare hand. With a broken cap, you can get a painful blow of a high.voltage discharge (up to 40,000 V with a slight current of current up to 80 milliamps).

The chainsaw is placed on the ground, pressed to the ground and slightly pull the starter cord slightly. At this time it will be seen whether there is a spark or not.

Failed search algorithm

In all other cases, the search for ignition malfunctions begin at the end and in order. After each step, check the spark.

Change the old candle to the guaranteed working.
If the model has a removable candle cap, it is removed, a bare candle wire is closed to a mass with a gap, approximately like a candle. Pull the starter. If there is a spark, problems in the cap. It is eliminated.
Change the candle wire where the ability to dismantle it from the source is provided.
Visually inspect the wires from the switch. With vibration, in case of contact with metal, they can be damaged. If there is a friction place, the wire is changed, even if there is no external insulation damage. To check the wire, you can use a tester or multimeter.

On this, small and easily eliminated problems end. If the problem is not solved, then the reason is more serious. Modern coils and ignition systems on most chainsaws are very reliable. They are designed for the life of even more than the entire chainsaw in general. They do not have mechanical moving details, as in old cam systems. They are insulated enough from clogging and moisture.

If an interval closing in a coil occurs in a random factory marriage or electronics fails, these parts are not subject to repair. It will take a replacement for new.

There is not a rare breakdown of a mechanical property. Due to wear or destruction of the crankshaft bearing on it, backlash appears. And then the magnetic rotor begins to touch the case of the ignition system, inside which it rotates. This is a serious breakdown. It will be necessary to “cut” (disassemble) the entire engine, replace the bearing, and collect everything in place.

The chainsaw is not started on hot

In cases where the chainsaws do not start hot, you need to conduct a visual inspection of all the main nodes of the chainsaw. Inspection should start with the spark plug. Check the spark, inspect the surface of the candle electrode, these actions will help establish the direction in which you should look for the problem.

Next, you need to inspect the fuel hose and its fastening to the carburetor, pay attention to, on the fuel leaks from the carburetor and the presence of gasoline in the air filter housing.

What to do if the chain saw does not start

Good afternoon, dear readers and subscribers of my blog! At some wrong moment you can find that your chainsaw does not start. But do not rush to immediately take the tool for repair, perhaps you yourself can eliminate this breakdown. I will tell you what to do in cases where the chainsaw does not begin, and how to find the right solution to this problem.

We analyze the possible causes of breakdown

Find why the tool cannot be launched in the instructions itself. But the instruction does not always come.

Although each model has its own characteristics, but in general they are all similar. Therefore, I will tell you about the possible reasons for the breakdown and possible solutions for different tools.

How the mechanism works

There are four elements in which problems may arise:

Fuel for which the carburetor is responsible;
Lubrication;
The air that enters the air filter;
Spark, the quality of which depends on the ignition unit.

All of them depend on each other and interact with each other. If any element works incorrectly, the saw stops working.

To begin with, all the tools are configured in different ways. Hot and cold. Two frequently used mechanisms are responsible for this process.

As you can see from the leadership, there is a fuel tank and engine inside the case, and outside. saw section (tire with a chain), handle and starter.

First we need to find out exactly how the tool does not start. For example, the saw begins, but immediately catches the eye or loses the power of work, the quality cuts.

Possible interruptions arise due to problems in the engine. But I would not recommend immediately making it out. It is better to look for a problem by the simplest option.

It is very important to consider the quality of fuel. If the mixture is prepared incorrectly or worsened over time, even such reliable tools as Urals or Husqvarna 145 will not work. The instructions must indicate proportions and special oil for your chainsaw.

Another common problem. During the launch, the user pours a candle. It must be checked if it is completely dry, then the fuel does not go into the cylinder.

The chainsaw is not started ! Fast and effective repair without costs!

If you see black carbon deposits or a lot of fuel, it is possible that the carburetor incorrectly regulates fuel supply.

If your sawn.uted start is launched, but immediately stops, the problem is to search for a carburetor jet or fuel filter. Perhaps they are clogged.

To check if the partition is damaged, it is necessary to disconnect the fuel hose from the carburetor and see if the fuel mixture flows from it.

If the saw does not start hot, the problem can be in the muffler. Sometimes it clogs from exhaust gases.

Quite often the saw gap occurs due to a small amount of lubrication for the chain. This happens with clogged channels or leakage of the oil pipeline.

Also check the joints of the pipes with the butter of the oil pump, as they flow.

Very bad when a failure occurred in the cylinder. When checking it, you can detect irregularities or chips, this can be the reason for the problem.

We restore the work of the tool

To restore the saw, it doesn’t matter the Ural or Calm brand, you need to know the location of the deployment.

First, we check and change the inappropriate fuel mixture. If the saw is still not starting, we check it further.

The problem is in the candle. Pull out and dry. In no case do not pierce it, because it will lead to a malfunction of the part. 30 minutes after drying you can insert the candle back before checking if there is any fuel in your place.

In addition, the candle may just break, so it is better to get rid of the cause.

, on which the tool is badly damaged and stagnated. This is a bad contact between candles and a high.voltage wire. If everything is in order here, but there are still no sparks, the ignition module itself may break. Such breakdown can only be eliminated by replacing it.

From time to time you must check and clean the air filters. If you have not checked it from the moment of purchase, he could clog from dust and cause a malfunction.

In models such as Calm 180, Ural or Partner 350 they score a respite, which often leads to breakdown. To clean it, you can use the sewing needle.

Models Stihl 180, Friendship, Ural and Huskvarna 142 sometimes clog the muffler, it also needs to be checked and cleaned.

If the problem is in the carburetor, then without appropriate experience you should not try to correct it. It is best to contact specialists.

If, after checking and eliminating the above problems, your saw does not start, then most likely the failure is hidden in the cylinder group.

When you saw damage and chips on the piston or cylinder, you will have to replace these elements.

If the cause of the chainsaw malfunction is a cork that proceeds, it is likely that an insufficient amount of grease is supplied to the chain. To solve the problem, the pipe is replaced only, and the seams are sealed with sealant.

Details of the mechanism cannot serve forever, so periodically they will need to be changed. To find out which part, you need to see the instructions.

Separately about the breakdown of the most common model

Consider the problems of Stihl 180 more details:

What is a sapun and how it affects the causes of the impossibility of starting a chainsaw

Few saws know about the existence of an element such as a ventilation hole on a chainsaw. This is one of the important parts of the tool that is responsible for balancing pressure in the fuel tank.

The principle of operation of the deflector on the chainsaw is that with a decrease in the amount of fuel in the tank, a vacuum or vacuum occurs. The smaller the fuel in the tank, the higher the pressure that becomes an obstacle to the fuel in the carburetor. To reduce pressure in the tank, a valve is used, which is a valve that allows air to pass in one direction.

If the ventilation hole is clogged, the air does not get into the tank, which means that the pressure begins to grow. On the cover of the tank of the chainsaw there is a sapun (depending on the model), and if the two.stroke tool of the tool does not start, it is necessary to check the operation of the saapon. Moving in the deflector malfunction is quite simple:

Unscrew the lid of the fuel tank. If the air flows, this indirectly indicates a malfunction of the pressure regulator
Twist the tank cover again, then try to restart the engine. If the engine starts, but after a while dies, it is necessary to clean the saepun
Another way to check whether the saapun is working is to disconnect the fuel line from the carburetor. If the fuel occurs periodically, the device works fine. If the dripping is weak and intermittent, it is necessary to clean the ventilation hole of the chainsaw to run the engine

Sapun (fuel tank cover valve) is cleaned with a pin. If the ventilation hole is highly clogged, the filtering element must be removed and cleaned. On different models of chainsaws, the deflector position is different (on most models it is in the gas tank cover). The video below shows the process of cleaning the ventilation opening using the example of the chausopila Husqvarna.

By putting a finger to the candle hole and pulling the starter, you can check the compression in the cylinder

If you feel that the finger is very drawn into the spark plug, then everything is in order with pressing. The absence of a vacuum in the cell indicates a malfunction. The piston cylinder node requires a more detailed examination, which will give an idea of the state of the piston and cylinder, piston rings and bearings.

Basil may not be launched in a cold state due to insufficient compression in the crankcase. The main reason for this is damage to the gasket located between the cylinder and the engine card. Detecting the lack of compression is quite simple:

If when the chainsaw is launched, fuel is sucked out of the lid, then everything is in order with compression. If not, see the gasket.

If fuel is absorbed, then everything is in order. the gasket is the whole. Otherwise, you will need to purchase a repair kit and replace it. How to do this, look at the video why the Chinese chainsaw is not started:

The main malfunctions and ways to eliminate them

Starting the repair of a chainsaw, you must have an idea of what malfunctions can have, and also how these malfunctions are eliminated. So, let’s look at the signs of malfunctions and ways to eliminate them.

Husqvarna chainsaw is not started

If Husqvarna does not start, the first thing you need to verify is that this is the following algorithm for starting the saw, as well as the presence of fuel in the tank. Detailed instructions on how to launch a cold chainsaw and its refueling is available in the guide to use a saw that comes with all Husqvarna chainsaws.

In the event that you do everything right, but the saw does not respond, the reason may be hidden in the malfunction of the ignition system or the absence of fuel supply.

For a more accurate determination of the causes of this behavior of the chainsaw, it is necessary to examine the spark plug, and then check it for the presence of a spark.

If the candle is wet, and when checking the spark, it is not found, it is worth trying to replace the candle itself. Replacement did not give results, so the problem can be hidden in the ignition coil, which is quite difficult to check on its own.

Check the serviceability of the coil, you can install it on a pre.good saw of a similar model or replacing the part with good.

In the event that there is a spark, and the candle is dry. problems in the fuel system. To eliminate it is necessary to carry out its full diagnosis. The fuel system consists of a carburetor and fuel line. Without a certain experience, you can check the fuel highway for impulses, as well as the cleanliness of the fuel filter installed in the tank. It is better to entrust the full diagnosis and repair of the carburetor to professionals.

If the saw starts, but bad

The cause of the difficulty launch of the saw may be a malfunction or incorrect carburetor adjustment. In the event that the carburetor shifts, the chainsaw will be easily started to be hot, but quite difficult to cold, especially after prolonged downtime.

An indirect sign of an excessive amount of fuel mixture entering the cylinder during the operation of the chainsaw is exhaust. If a lot of white smoke is released when the chainsaws are released, it is worth checking the proportions of the preparation of the fuel mixture and adjusting the carburetor.

The chain of the chainsaw is spinning at idle

If the Huskvarna chain rotates at idle, then we can conclude that there are malfunctions in the clutch mechanism or idle speed is not adjusted. To eliminate the malfunction, it is necessary to remove the brake cover of the saw chain and inspect the integrity of the clutch spring. Replace defective clutch.

If the clutch is regular, to eliminate the scrolling of the circuit, it is necessary to adjust the idle speed using the adjusting screw indicated by the letter (T) or to complete the carburetor adjustment.

Important: a possible reason for an independent increase in the idle, is the appearance of air leaks in the engine or carburetor crankcase, which can lead to serious damage to the CPH.

Why is the Husqvarna chainsaw stall when you press the gas

If the saw stalls immediately after pressing the gas, it is necessary to examine the spark plug, which will help to more accurately diagnose the malfunction. Wet candle indicates a malfunction or improper adjustment of the carburetor, in this case, you can correct the situation by carrying out a complete diagnosis, repair and adjustment of this unit. If the repair and adjustment did not help, it is necessary to replace the carburetor with a new.

Another reason why Husqvarna can stall when pressing gas is a malfunction in the fuel system, or rather, difficulties in supplying fuel to the carburetor. It is necessary to check the cleanliness of the fuel filter, as well as the integrity of the fuel hoses.

In the process of assembly of the chainsaw during its full repair, you can squeeze the fuel hose that goes from the tank to the carburetor, which will limit or completely stop supplying fuel and make the saw it is impossible.

Why is the chain on the Husqvarna chain not lubricated

If your chain is completely stopped on your chainsaw, then you need to check the entire oil system.

Oil pump malfunction;
Blocking the filter element installed in the tank;
Malfunction of the oil tank saopun;
Rupture of an oil hose;
Mismatch of the oil opening on the tire and on the saw case (if the supply stopped after installing a new saw tire);
Blocking the oil canal in the saw case;
Blockage of the oil supply channel in the bus;
Oil pump drive malfunction.

Self-repair of Husqvarna chainsaws is possible only if there are at least some knowledge about the operation of a two-stroke engine, as well as the principles by which a chainsaw is arranged. As practice shows, it is not difficult to disassemble the Husqvarna chainsaw, it is much more difficult to assemble it and at the same time not aggravate its malfunction. Calculate your strength in advance and do not hope that you can repair the saw without some experience. In some cases, even experienced craftsmen make a lot of efforts to correctly diagnose the malfunction.

Chainsaw is an indispensable assistant for every real owner.

Since the appearance of the instrument, its popularity has increased rapidly.

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

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

Hookkurna malfunctions 240

Like any technically complex tool, the 240th saw sometimes breaks. Situations when a chainsaw does not start or stalls when pressing on gas, although infrequently, they happen. Consider the main reasons for this behavior of the saw.

Why not starting chainsaw Husqvarna 240: Causes

If Husqvarna 240 does not start, check the presence of fuel, t. to. Sometimes you can simply forget to season it. If the tank is refuel, and the chainsaw is not started, the reasons may be as follows:

The fuel filter is very contaminated, to eliminate it is necessary to replace the filter;
A rush of fuel line. It can be found visually on the fuel leak;
The coil or light of the ignition is faulty. To determine the malfunction, you will need to check the spark on a deliberately working candle. Also, if there is no spark, it is worth paying attention to the gap between the flywheel and the ignition coil and, if necessary, adjust it;
malfunctions in the engine control button, to check, you must disconnect the wires from the button and try to launch the Husqvarna 240 chainsaw;
A strong air pump in the fuel pump of the carburetor, it is necessary to check whether the screws of the mounting of the fuel pump of the carburetor are tightened;
Cutting the pulleric. The malfunction can be detected with a carburetor removed;
Incorrect adjustment of the carburetor. It is possible to proceed to adjust the carburetor, only after all other elements that are responsible for the proper operation of the engine are checked. Otherwise, when adjusting you can only harm;
The reason that the engine does not start is hidden in a malfunction of the CPH, for example, sticking the rings, the bullying of the CPH, etc. D. In this case, in diagnosis, a complete disassembly will be required, which is best entrusted to specialists.

Reviews of the owners

The gap that affects the work of the saw is very important. She stalled with me, sneezed at startup and I could not do anything. And was lying idle until I read about the importance of the gap. If you cut it correctly, then you add problems for yourself.

There was such a problem: the chainsaw started well, but when adding gas began to sneeze and stall. Checked fuel and air filters, everything is fine. It turned out to be a carburetor. It turned out on the diagnosis. So I gave it to the service center so as not to wave my own. The guys fixed everything. stopped sneezing and stall.

The chainsaw is poorly started on the cold

Violation of the sequence of actions when starting to cold

If a new chainsaw is not started to cold, then the reason may be in the wrong sequence of engine start. As a rule, each manufacturer in the instructions for the chainsaw indicates the procedure for the start of the chainsaw to the cold. It is mainly similar to all two.stroke internal combustion engines that are installed on the chainsaws, and is the following procedure.

Closing the air damper (it is necessary to enrich fuel during starting).
The fuel suction using a special primer for this (on some models of chainsaws, the primer is not provided for by the design, and therefore this item is absent for them).
Turning on the ignition (if you forget about it, then you can mistakenly calculate the tool faulty).
To carry out several starter movements to the first “outbreak” of the engine (it is important not to miss this moment, otherwise it is possible to “fill” the engine).
Set the air damper to the position openly.
Start the chainsaw engine.

Fuel problems

As in the option of difficult to start hot, problems in the fuel system can affect the launch or not the opportunity to produce it and on the cold. Adjusting the carburetor, contamination of the fuel filter and the highway, all these are the reasons that cause difficulties when starting.

Diagnose the fuel system, this is the first thing that needs to be difficult for the cold.

It is worth paying attention to the quality of fuel, t.to. When using a mixture of gasoline with butter, in which there is a small amount of water, it may be much difficult to start or become impossible.

The mixture must be used fresh enough, t.to. When storing oil diluted with oil for more than a month, its properties are lost and complicates the launch, both on the cold and on a hot engine. Gasoline for this reason can burn poorly.

Malfunctions in the engine

ZPH dumbings, sticking of rings, wear of the CPH, air leaks through seals and gaskets, lowering compression, all these problems can make the chainsaws impossible or significantly make it difficult to make it difficult. For example, with not significant wear of CPH, compression in the engine is reduced. In this case, the launch on the “cold” will be much difficult, or the saw may stop. The tool will start well.

It is quite difficult to accurately diagnose problems in the engine in its launch problems, and it will be better for this to turn to a specialist in this field.
