Why does the chainsaw only work on the leak

And, there is still between the “output” of the carburator and the rubber “knee” there is a ring, with the side in the inner diameter. this side should be inserted, into the carburetor or elastic band ?

Basil starts and stalls the reason

Owners of chainsaws sometimes have to face the fact that the saw, for no apparent reason, ceases to work normally. I figure out why the chainsaws stall at various operating modes, and also describe how the malfunction can be diagnosed, we will try in our article.

The situation in which the chainsaws are started, and in the process of heating can stall, is familiar to many who are dealing with them. The main reasons for this behavior of the saw are the following.

• The ignition module is faulty (coil). You can determine the malfunction by checking the spark first on the cold engine, and then on the hot. If there is no spark on the hot engine, then it is worth trying to eliminate the malfunction by replacing the ignition coil.
• The carburetor of the chainsaw has the wrong tuning (floods the candle on hot). You can determine the problem by the saw starting on the cold. If for cold starting it is not required to close the air damper, and the engine is launched without a preliminary flash, then the fuel mixture is formed incorrectly and after heating the engine, the fuel flies a candle and makes the launch impossible. The problem is eliminated by the adjustment of the carburetor.
• The spark plug is faulty. In such a situation, similarly to a faulty ignition coil, a spark disappears when the engine is heated. It is worth trying to replace the candle with a new one, and if this did not help, then you need to check the ignition coil and the gap between it and the flywheel.

You can check the ignition coil using a multimeter or replacing it with a deliberately serviceable. Checking the primary and secondary winding multimeter is carried out in the mode of resistance measurement mode. The indicator of the resistance of the primary winding, the working coil, is 1 kOhm. secondary 4 rooms.

The main elements of chainsaws

Before starting to delve into the issues of breakdowns and repairing the tool, let’s first figure out what the chainsaw consists of actually. At first, I would like to note that this tool belongs to the category of technology, whose work directly depends on the gasoline engine.

It is also important that the chainsaws are equipped with an engine with one cylinder, and whose work is done on such a fuel as gasoline. It should be noted that, without looking at the similarity with other tools, it does not have a gearbox. And it is replaced by a typical chain single.stage transmission, a means of which the movement of the chain itself is made (saw).

In fact, chainsaws are a rather ordinary design, but this does not prevent it from being reliable, comfortable and capable of entirely ensuring specific uninterrupted and cyclic work even in rather complex criteria. This tool consists of a huge range of certain parts of “vital” for the correct and productive work. This is a carburetor, a device of a specific chain tension, a tire equipped with a chain and other elements.

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

To simplify the choice for you, we compiled you the rating of the chainsaws by reliability.

If you have a limited budget, then read the article about Russian manufacturers of chainsaws.

Characteristic and possible causes of breakdown. DIY problem Eliminating the problem

Chainsaws are rather reliable and light designs. Therefore, if it is true to care for them and treating them, starting from the advice of the manufacturer, then they fail, well, very occasionally and various kinds of breakdowns are quite rapidly eliminated. But if you are faced with this situation and want to personally repair your own tool without resorting to the help of experts, then delve into the information presented below.

In fact, it is unambiguously and accurately impossible to determine the reason why the tool does not start or stall when pressing on gas, because there are quite a lot of reasons for affecting it. But we should not forget that starting from the fact that the chainsaws are armed with an ordinary two.stroke engine, such conditions as lubrication, fuel, spark and air are important for its effective performance.

As follows, the manufacture of the fuel-air consistency is specifically engaged in the carburetor, the filter makes air cleaning from dust, the sparking unit and the candle make a spark, and there is a lubricant in the gasoline.

That’s why it is necessary to search for the circumstances of this kind of breakdown in an alternate manner, starting specifically from the lungs and evenly moving to complex. And this is a fundamental factor in the correct repair, because the person who, without thinking about the analysis of the carburetor, leads it to the risk. Because such a node should be repaired or regulated directly in special workshops (read about the adjustment of the carburetor).

It is important that for the non.precise activity of the tool it is necessary to carefully attribute directly to the fuel. Since if this kind of mixture is not prepared correctly, then most chainsaws simply will not start. Therefore, not every owner will guess to look for the cause of the fuel breakdown. That is why your tool always works correctly for a mixture to use exclusively high.quality gasoline.

Carburetor check and adjustment

In service centers, carburetor adjustment is made on special equipment. For each saw, the values ​​of the rotation angles of the adjusting screws are different (they are indicated in the operating instructions). The need to adjust the carburetor does not arise very often, especially if the saw was bought from a proven seller. All our Husqvarna saws are sent to the service center before selling, where experts set up revolutions.

However, a violation of fixation of adjusting screws sometimes happens.

Causes of violation of adjustment of the carburetor of the chainsaw:

• Strong wear of the engine (piston). In this case, it is necessary to take a greater extent to fix the engine, however, the carburetor adjustment can improve the functionality of the saw for a certain amount of time.
• Blockage in the carburetor due to damage to the air filter, the use of poor quality gasoline and the formation of scale.In such a situation, in addition to adjusting the carburetor, it will also be needed to flush.
• Strong vibration of saw or damage to the protective cover. This is extremely rare, but there are still cases.

Signs that indicate the need to adjust the carburetor of the chainsaw:

• The engine either does not start, or starts up and immediately stalls. This is due to the use of poor fuel mixture.
• A significant increase in fuel consumption and an increase in exhaust volume. the amount of exhaust gases suggests that the fuel does not completely burn out. The reason for this can be oversatuity of the fuel.

The carburetor adjustment scheme for different models of the chainsaws is different and described in the operating instructions. However, the general principle remains the same: it is necessary to change the quantity and quality of the fuel mixture supplied to the engine cylinder.

Three screws will help us to adjust the carburetor:

• “L”. LOW, to configure low speeds
• “H”. High, to configure the upper revolutions
• “T” (“LA”, “S”). to configure the idle stroke (the models that have only one screw have exactly the “T” screw)

When adjusting the carburetor of the chainsaw, the following rules should be followed:

• Make sure that the cutting chain of saws is directed in the opposite side of you
• Put the saw on a stable even surface, the cutting part should not touch any objects.

Please note: the instructions indicate the exact angles of rotation of the adjusting screws. Accurate compliance with the instructions of the instructions will avoid engine damage.

The process of adjusting the carburetor itself includes two points: basic (with a non.working engine) and final (with a heated engine).

The basic setting of the carburetor

Slowly wrap the adjusting screws of the maximum and minimum revolutions (h and l) until it stops clockwise, and then by one and a half turns in the opposite direction.

First we warm the engine for 5-10 minutes (not at high speeds).

We adjust the idle stroke

Now, by turning the idle screw (t, la, s) counterclockwise set up the minimum number of revolutions in which the engine operation is stable. The chain should not move. If the engine stops at idle, then accordingly turn the idle screw clockwise. If the chain moves, turn the screw counterclockwise.

For the final of the tuning of the chain saw carburetor, we check the engine for acceleration and maximum speed.

Check acceleration

We smoothly press the accelerator and watch how quickly the engine is gaining momentum from idle to maximum power. If the engine is gaining momentum slowly, therefore it is necessary to weaken the screw L (low revolutions), turning it a little counterclockwise (not more than 1/8 turnover).

We set up the maximum speed number

As mentioned earlier, the maximum speed is tuned using the screw H, the turns increase when it is twisted clockwise, decrease when turning against the hourly.

The highest rotation speed of gasoline chain saws is in the range of 11,500. 15,000 revolutions per minute, depending on the model. Higher speed is dangerous for the engine, which will not allow it to start. Maximum turns can be determined by interruptions in the ignition. If any, turn the screw h counterclockwise.

Once again, check the chainsaw at idle

As soon as we configured the acceleration and maximum speed, we again check the operation of the engine at idle. We will understand that we adjusted the carburetor correctly if:

If at least one of these conditions is not respected, adjustment should be re.carried out (excluding the basic stage).

Why the chainsaw is not started

If defects occur, it is necessary to check the serviceability of the components.

If a new chainsaw is not started, you should check the presence and supply of fuel, the occurrence of a spark on the spark plug, the functioning of the exhaust valve, the condition of the filters. The work of a saloon stalling device built into the fuel cover of a stalling device.

The reason that the Chinese chainsaw is not started can be poor.quality equipment. It is possible to have various malfunctions, incorrect assembly. Some goods come to defective. If the inspection has not revealed malfunctions that can be eliminated independently, you can replace the saw on the warranty coupon.

On the cold

The reason why the device does not start on the cold is often a violation of the sequence of engine start.up.

You should familiarize yourself with the instructions: manufacturers indicate how to properly launch a chainsaw.

To enrich fuel, you should first close the air damper. After that, fuel suction is produced. For this, a special primer is used. Then turn on the ignition. Until the first outbreak of engine, several starter movements need to be made. The damper opens, the device is launched. If the sequence is violated, any step is missed, incorrect work is possible.

If the chainsaw has stopped starting, the probable reason is the problem with the fuel system. Non-varnishes with launch can occur due to an incorrectly adjusted carburetor, clogging of the highway and the fuel filter. The quality of fuel is also important. If the fuel is diluted with water, the device is poorly started or does not work at all. The mixture should be fresh.

A possible cause of problem launch is engine malfunction. Wear or breakdown of the part leads to undesirable consequences: reducing compression in cylinders and other troubles. It is recommended to contact specialists with such problems, since it is difficult to diagnose and fix the breakdown independently.

Hot

If the chainsaw is poorly started to be hot, you should start an inspection of the tool from the spark plug. It will also be required to check the spark on the candle.

So that the device works properly must be a dry candle. When it is wet, there are no sparks on the contacts. You can try to replace the part with a new.

If there is a spark and the candle is in good condition, try to look for a problem in the fuel system. If, upon visual inspection, it was not possible to detect the cause of the breakdown, the carburetor should be removed. If the amount of fuel exceeds the permissible, the device will not work. The candle should be wet. Should turn the candle hole down down. If the fuel mixture is pouring, the reason why the chainsaw is not started on hot, there will be an excess of fuel.

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.

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 contaminated, 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.

Chainsaw does not throw back speed

In some cases, the benzoin acetic regulation quickly reaches a certain level of power and does not reset speed. To eliminate it is not enough to adjust the screws on the case or clean the carburetor. The essence of the problem in the large consumption of the fuel mixture.

The following actions are performed:

• The serviceability of the gas cable is checked;
• The return spring is being examined. it can jump off;
• The back damage should be completely tight.

The chainsaw itself is gaining momentum

There may be a problem when the saw itself begins to gain momentum. Working, the unit stalls, not allowing to fully use a chainsaw.

Factors that can provoke the failure of the unit:

• Carburetor, fuel or air filters clogged;
• The fuel step was damaged or clogged;
• The leading pipe between the carburetor unit and the motor cylinder was depressurized;
• The problem with the screw settings (often N-vinta) of the carburetor.

The following works are performed:

• Carburetor and filters are cleaned. In this case, the correct setting of the screws l and h is controlled.;
• The fuel filter should not be removed, since this will negatively affect the duration of the instrument service. It is enough to check whether it is fuel, the hose for the supply of fuel should not be curved.

Problems with the working revolutions of the chainsaw can arise in any situation. Therefore, it is important to carefully refer to the benzo tool, to carry out maintenance and diagnostics in time. Correct and timely work will quickly restore the working functions of the saw.

Summing up

When the first signs of incorrect operation of the chainsaw appear, it is worth performing its full diagnosis. In order to avoid damage to the saw as a result of improper maintenance, it is better to entrust the work to determine and eliminate engine malfunctions. And most importantly, you do not need to use a chainsaw with minor defects, t. to. This will lead to even greater problems.

Hello, dear subscribers and readers of my blog! In touch Andrey LOC. We continue the topic of chainsaws. So, I already said before what should be checked in a chainsaw in order to know the cause of its malfunction. Today I will switch to more valuable instructions so that you do not look for the reason for the problem for a long time and know about how to solve it. Not the most difficult tool, but you need to care for it correctly. There are different cases, sometimes the chainsaw stalls when pressing gas, sometimes in a load, and sometimes does not work at all at all. Let’s look at different situations together and try to find the right solution.

If you find that the tool does not start and stalls at all, then you do not need to rush immediately to the service center, you can try to solve the problem yourself.

We check the main chainsaw systems

We check each system sequentially:

• Fuel tank. Perhaps there is not enough fuel or it is poor.quality.
• The next to the check is the spark plug and the high.voltage wire. Please note that the gap of the candle is normal does not exceed half a millimeter.
• If the above points are checked and work correctly, go to the carburetor and fuel filter. With a breakdown of the carburetor, you need to contact specialists.

Why is a chainsaw is not gaining momentum. reasons and solutions

The launch of the engine of the gasoline chain saw is a multi.level procedure, during which almost all the nodes of the tool are driven into effects. One of the first signs of malfunction of the chainsaw motor is the absence of an increase in the speed of the internal combustion engine. This can manifest itself in different ways: the engine can work with interruptions at idle, or not gain the required speed at load. That is, while pressing the gas trigger. In any of these cases, you need to disassemble the tool and carefully inspect its internal structure.

Breakdowns, because of which the chainsaw does not develop momentum, serve:

Engine malfunction. The first thing that can happen is the wear of the motor, that is, its final production. This will be indicated by numerous scuffs and burrs on the surface of the parts of the CPG, deformation of the crankshaft or through flashes within other parts. In this case, the only thing that can help is the replacement of the motor, which is equivalent to buying a new chainsaw;

• violation of the settings in the carburetor. if steel nozzles on the fuel node were displaced, they will need to be installed according to the instructions for operation;
• oil.flooded or faulty spark plug. The first thing to do is to clean the candle from dried engine oil. If this did not help and the saw still does not gain momentum, then the candle will need to be replaced.

When cleaning the candle, you need to be extremely neat so as not to damage its tip. He is responsible for the formation of a spark necessary for ignition of fuel.

Why gaspes a chainsaw

One of the malfunctions of the chainsaw is that it during its work ceases to obey the gas button. The chainsaw does not drop turns and it remains only to turn off the ignition. This happens quite often.

The most common causes of such breakdowns

• One of the banal reasons why the chainsaw is discharged is the carburetor pollution. Motopila carburetor must be removed and disassembled to the maximum. Details of the carburetor for a day are soaked in pure gasoline. If necessary, repeat the procedure again. Strong pollution is cleaned with a brush. After that, spare parts are dried and assembled in the reverse order. The cleaned parts are examined before the assembly, since only after their cleaning can defects hidden mud. How to disassemble and assemble a chainsaw carburetor there are many tips on the Internet and this is a separate topic.

• If the chainsaw itself is gaining momentum of one of the reasons may be an adjusted throttle valve of the carburetor. It is directly related to the quality of the mixture, enriching the fuel in the right proportion. Adjustment is carried out at idle engine. With a properly adjusted carburetor damper, the chainsaw works evenly, and the saw chain does not move along the tire on idle. During operation, the chainsaws from time to time carry out such an adjustment.

• Иногда причиной по которой газует бензопила является подсос воздуха в какую то часть топливной системы. Or rather, it would be possible to say an outflow of air from the system. For this reason, the fuel will lack a certain amount of air for normal operation and the engine speed will increase. The fuel mixture becomes impoverished into the air and re-enriched gasoline. In such cases, you should carefully examine the entire fuel system starting from the tubes to the carburetor.
• Basil during operation creates normal vibration from which bolted carburetor joints can weaken. This is also one of the reasons for the air suction from under the gasket. Such places must be systematically pulled up.

• There are times when a chainsaw does not reset the momentum due to the fact that the accelerator cable is clamped. On some models, there may not be a cable, but a metal rocking, which can fly. We disassemble the handle on which the gas button is located and inspect the accelerator mechanics.

• If the crankshaft oil seal damage, air leaks from the fuel system can occur. The crankshaft during operation heats the oil seal and over time it grows that it leads to a loose connection. The oil seal is changed.

It is necessary to carry out the repair of a chainsaw, taking into account the recommendations of the manufacturer’s factory. It should be noted that now there are no problems with spare parts for motorcycles in our country. Therefore, you can repair it yourself with little Malian experience in technical matters and having a desire. Our online store provides a factory.made chainsaw with further advisory and technical support for a warranty and after a warranty life.

Chinese chainsaw itself is gaining momentum and stalls. Reason and repair

When cleaning the candle, you need to be extremely neat so as not to damage its tip. He is responsible for the formation of a spark necessary for ignition of fuel.

How to avoid premature breakdowns? Chainsaw service tips

Your assistant should be the operating instruction. If you have lost it, you can contact the dealer of the company, which you use, will provide you with electronic instructions.

So, before each inclusion of a gasoline chain saw, be sure to make sure that the chain is working, whether its teeth are sharpened, whether it is stretched well (not sagging, but not too tightly stretched, it can be slightly pulled away from the canvas).

You can sharpen the chain using a special machine or file with a special template (depending on which step to the tooth of the chain, there are different templates).

Each time after use, the chainsaw must be cleaned: a chain, a tire, an air filter, a case, cooler ribs, cracks and other grooves are cleaned of sawdust. After using the saw, we turn the tire so that it wear out evenly, lubricate the star (if there are grooves for lubrication in the front of the saw).

With prolonged storage, be sure to drain fuel and oil! The chain and tire form an electrochemical pair, because they rust together, they need to be stored separately.

What to do if the chainsaw herself is gaining momentum ?

This malfunction is typical for novice gardeners, ignoring the need for timely maintenance of their benzo.tool. In the case of an arbitrary set of revolutions, the reason should be sought in a carburetor. First of all, it will need to be completely disassembled. Having made sure of all the built.in parts, you can start washing the fuel node. For this you need:

• Place all the elements of the carburetor in a container with clean gasoline. After the knocks of the details, you need to extract, thoroughly rinse them with water and dried;
• Fuel tubes must be blown out by compressed air from the cylinder. Immediately before the return installation of the hoses in the places of their connection to the fittings, it will be necessary to apply silicone sealant;
• After installing the carburetor, not a chainsaw must be adjusted to adjust it. Before this, you need to make sure that the power unit is working, as well as in the working condition of filters, rubber gaskets and bushings.

In some cases, the cause of arbitrary setting of a chainsaw can be the loss of sealing crankshaft. Due to constant contact with a moving shaft, the oil seal is excited, which leads to the formation of cracks and holes inside it. Damaged laying is not subject to restoration, so it must be replaced.

Often the cause of the air leakage, due to which an arbitrary set of revolutions by the engine occurs, is the loss of fixation of bolt compounds. In this case, the operator will need to tighten all the bolts and again check the work of the benzo tool.

Other malfunctions of chainsaws

A lot of users are faced with trouble when the chainsaw does not throw off the moment. The device in a matter of seconds reaches maximum power, which cannot be reduced.

• The throttle does not function. its spring or an element of traction weakened;
• The switching tumbler is poorly switched;
• The shaft of the throttle.

But there may be the opposite situation. when I drank uncontrollably gaining power. The reasons why the chainsaw herself is gaining momentum, you need to look for in:

• carburetor. it must be cleaned or reconfigured;
• fueling system. a gasophiller, fuel hose;
• malfunctions of cylindrical piston or pipes connecting them to the carburetor.

Breakdowns that manifest themselves through a momentum atypical for a particular part of the working cycle, quite a lot. But an attentive attitude to the tool will help to diagnose them in time and return it to normal work.
