If you poured a candle in a chainsaw. Characteristic

The reasons why flies a candle on a chainsaw and ways to eliminate them

There are several common reasons for overflowing the combustion chamber, but, fortunately, each of the possible problems can really be eliminated without special skills. Among the actual reasons for filling the candle can be distinguished: an error at the first launch, a carburetor defect or clogging of an air filter. To get an extremely complete performance and understand why it fills the candle on a chainsaw, it is better to get acquainted with a brief analysis of each problem.

An error at the first launch of the saw (on cold) is expressed in the excessive supply of the fuel mixture after several extra starter rotations. Distracted, or by inexperience, you can skip the moment of ignition and continue attempts to launch. Since the air damper at this stage is closed, with each starter jerk, only the fuel mixture will enter the camera, which will be recruited without the possibility of ignition. 5-10 extra revolutions are enough to pour contacts, after which the engine will no longer start, even if you open the damper.

Carburetor defect does not occur from scratch, but after prolonged storage of the tool without draining fuel. A mixture of gasoline and oil begins to break up already in the first month, reacting with miniature components of the mechanism that it envelops. First of all, the membrane grieves, violating the rhythm of its work. The axis of the float (rocker hand) grossed, making it difficult to include, and the tip of the needle is eaten, reducing the tightness. Even one of the 3 indicated defects is able to upset the operation of the carburetor system, which will not be able to restrain the moderate supply of fuel.

The clogging of the air filter occurs after several tens, or even hundreds of hours of operation. The reason is so banal that sometimes they lose sight of it, passing on to other options. Mud clogs pores, seriously reducing the throughput of the material, and therefore the speed gradually falls, and with severe gesture, the chainsaws are burst and stalls stall. The condition of the filter is easy to evaluate “by eye” by examining it at the time of taking out the candle for verification (they are under the same lid).

Repair of the carburetor

First of all, the defective element must be removed from the tool system. Remove the top cover with an air filter, remove the candle and unscrew the plastic frame. Often, the carburetor is attached to the engine with two screws, which should be unscrewed and removed the air damper lever. Next, disconnect the fuel hoses and remove the gas control lever.

After extracting the carburetor, unscrew the fasteners of the adjusting chamber (usually 4 screws) and remove the membrane with a gasket. If the membrane is coarse, it should be replaced, but in the absence of such an opportunity, you can boil in ordinary water for about 30 minutes. With wear and damage. only replacement.

We move on to the next problematic component. needle. This miniature detail, along with the axis and float, holds the screw hat, which must be unscrewed.

We take out the structure and install a new one from the reptile complex.

If there are no new details, you can try restoration. The float should not hook behind the axis when scrolling, and if this happens, it is better to sand it with zero sandpaper, inserting it into the cartridge of an electric screwdriver. The end of the tongue of the rocker should be in the level with the faces of the carburetor body. When polluting the needle, it can be cleaned with a sharp blade or felt, holding in an electric screwdriver.

We collect pure and serviceable components in the reverse sequence. the needle, axis, rocker, fixing screw, gasket, membrane and cover.

We install the assembled carburetor to our workplace by connecting the fuel hoses and gas control levers / air damper.

What to do when floods a candle on a chainsaw

Before going to the service center, it will be useful to independently try to eliminate the current fault of flooding the candle on the chainsaw. Of course, this is relevant only in the presence of “straight” hands, since, otherwise, it is likely to increase the cost of repair work.

Poor.quality fuel

The chemical composition of low.octane gasoline includes various alcohol components. It takes more time to complete combustion than when using high.quality fuel, respectively, this becomes the main reason for the failure of the chainsaw candle.

Unfortunately, many citizens naively believe that the fuel with the inclusion of alcohol has a positive effect on the consumption of gasoline and acquire fuel surrogates. In some cases, economy really takes place, however, such fuel negatively affects the chainsaw engine, reducing its service life.

Incorrect launch

As a rule, during the first launch of the chainsaw, inexperienced men miss “cotton” with a closed air damper and continue to pull the starter. Because of this, a large amount of fuel accumulates in the combustion chamber, but there is not enough air. The candle is poured with excess gasoline and there can be no question of any spark.

The clogged filter

Due to the strong pollution of the paper filter of the chainsaw, a sufficient amount of oxygen does not enter the fuel chamber. The fuel mixture does not have time to ignite and gasoline fills the candle. If the filter has already developed its resource (this will be noticeable in its appearance), then it must be replaced. If the new filter is not at hand, but it is still necessary to work, then you can try to blow the filter in the back air flow.

The chainsaws of various manufacturers and model rows differ from each other. To clean or change the filter, it will be useful to initially see the operating manual. Well, or look there if you can’t extract a filter without tips.

Ignition system failure

Perhaps this is one of the most difficult problems that will need to be overcome for the further use of a chainsaw. The causes of the malfunction here can also be several.

The wrong gap

For the most part, the gap on the lighting candle of the chainsaw should be within 0.5. 1.2 millimeters (more accurate data should be reflected in the user guide). In order to check if this is, it is necessary to perform the following actions:

• Using a screwdriver or special keys, the bolts are unscrewed that fix the chainsaw cover.
• Having gained access to the flywheel and the magnetic circuit, the level of gap is checked.
• If it does not correspond to the characteristics declared manufacturers, then with the help of a special laying or improvised means (an ordinary A4 sheet, folded several times) is perfect).

Problem in the ignition coil

To make sure the ignition coil is in good condition, you must be able to use a multimeter. This device allows you to measure the degree of reel resistance. There will be resistance in the good coil. In the burned out. cliff or short circuit.

If the coil is in good condition, then the gap between the coil and the flywheel may be broken. To configure it, you need to perform a number of simple actions:

• Dismantling the saw case and the weakening of the bolts on which the ignition system is recorded. To the coil itself, you need to bring the magnet (magneto) of the flywheel.
• The adjusting plate is inserted between the magneto.flywheel and the coil itself. The gap should be within 0.2 mm.
• After tightening the bolts, the plate for adjustment is obtained.
• It is necessary to completely and several times (2-3 will be enough) scroll the flywheel. While he should not cling to the coil.
• The final stage is the assembly of the chainsaw building.

Carburetor adjustment failure

Often the candle on the chainsaw flies due to the incorrect operation of the carburetor. For greater clarity, we recommend watching this video

If you first set up the carburetor yourself, then pay attention to the following factors:

• The presence of built.in compensators and other automatic control elements makes it impossible to adjust without special equipment. In this regard, you will have to contact a specialized service center.
• In the absence of the proper effect of adjusting the carburetor, the cause of filling the candle will be, there is a freezing of the float or the lack of tightness of the valve.

Assembly Partner 350

In order to properly collect the Partner 350, it is necessary to install all the elements in the reverse sequence with removal.

If you first encounter the repair of the Partner 350 chainsaw, then when disassembled, lay the details in the order in which they were removed. This will allow you not to get confused and not forget to install any node.

An important feature of assembly of the Partner 350 chainsaw engine is that the crankcase cover is installed without laying. Instead of it, a red sealant is used, which is applied with a thin layer to the installation site of the crankcase. Before applying a sealant, it is necessary to degrease the crankcase cover and its installation place, for better adhesion of the sealant.

Installation of the gap of the flywheel and coil (ignition adjustment)

During the assembly process of the Partner 350 chainsaw, if not only the flywheel, but also the ignition coil was removed on it, it is necessary to set the gap between them. To do this, the flywheel is first installed, then a piece of a half.liter plastic bottle is laid on it, and then a coil is placed and fixed with two fasteners, while the flywheel should be turned to the coil with magnetic contacts.

After adjusting the clearance, crank the flywheel. If he does not hurt for the coil contacts, then the gap is exhibited correctly.

What to do if a candle is flooded on a chainsaw

If you suspect a flooded candle, it is necessary to inspect it. With the help of a candle key, it is twisted and carefully studied. If the candle is wet, but at the same time there is a spark, then it was definitely flooded.

Many experienced owners are able to determine the current state of a candle by its color with a high degree of probability. A similar procedure is recommended to be carried out regularly.

• Light brown Nar is exactly what all owners want to see. In this case, the functionality of the chainsaw is not impaired.
• Black carbon car signals an unbalanced mixture, namely, the lack of oxygen in the fuel chamber. If the situation does not improve, there is a great probability of re.filling the chainsaw candle.
• In the case of corrosion on a fork or too much distance between the electrodes, then, most likely, a lunch fuel mixture is used.

main parameters

Any candle has unique characteristics that must be taken into account when buying this consumable. The most important of these parameters are indicated in the instructions for the tool and in the marking of the product itself. The main characteristics are considered:

• a gap that shares electrodes;
• the diameter and step of the thread;
• thread length (skirt or candle shirt);
• the material from which the head electrode is made;
• Green number.

In addition, you can find out information about the manufacturing company, the design features (number of electrodes), the presence of a built-in resistor and the height of the insulator from marking.

Each of these parameters will help the owner of the tool or device with a two.stroke engine choose an adequate replacement for the failed ignition candle in cases where such a model is not in specialized stores.

Interruptions in work

To restore the saw, it doesn’t matter the Ural or STIHL brand, you need to know the place of dislocation of the breakdown. First, check and change the unsuitable fuel mixture

If I still did not start, then we check further on the items

First, check and change the unsuitable fuel mixture. If I still did not start, then we check further on the items.

The problem is in the candle. we pull out and dry. In no case should you pierce it, because this will lead to a malfunction of the part. Flies a candle on a chainsaw: what to do? 30 minutes after drying, you can insert a candle back, before checking if there is no fuel left in its place.

Benesopila has not been considered innovative techniques intended exclusively for professionals for a long time. Today, many summer residents and owners of personal plots have a similar universal unit in their arsenal. After all, modern manufacturers offer customers a wide selection of types and models of units of this kind.

If we provide the equipment of such a plan, proper use and maintenance, the STIHL chainsaw candles are unusable extremely rare. But if one day the chainsaw did not start, you need to understand the problem in order:

The spark plug for a chainsaw is an important part as units of this kind. If problems arise with it (for example, it floods it), then they can lead to a breakdown of all equipment; If, when examining a candle for a chainsaw, the touch is completely dry, then this indicates the absence of fuel supply. Why is this happening? The salt of the problem is concentrated in the carburetor. Be sure to clean the fuel filter and turn on the engine again. Nothing happens? Then the carburetor needs to be disassembled and studied, but it is better to entrust this business to specialists from the service center; If the unit does not start, then this may indicate a problem with spark plugs of a different nature. it floods it. You have a stihl chainsaw: floods the candle and the unit engine does not start? To eliminate the problem, turn out the flooded light of the ignition and dry it well. In this case, it does not need to be pumped. It is enough to drain the fuel mixture from the candle hole and leave the part to dry for half an hour. Next, install it again and start the motor

In addition, it is important to inspect the contact between the tip of the spark plug and the high.voltage wire; It is important to ensure that the gap of the spark plug of the chainsaw is correctly adjusted.

Why flies a candle on the stihl chainsaw? The answer is simple: this occurs when the unit is launched by an inexperienced user who does not comply with the correct sequence of launching equipment to cold.

Because of this, the candle tip may fail. To verify the presence of such a problem, unscrew the candle and insert it into the tip. Then put the part on the block, and pull the launch cord several times. If there is a spark, you can not worry about the electrician and the state of the candle.

Be sure to check that the gap of the spark plug of the chainsaw is adjusted correctly.

The consequences of the engine with unexplored fuel equipment

The traction characteristics of the engine and the duration of its resource depend on the composition of the mixture.

• Work on a poor mixture initiates a drop in power, overheating of the cylinder and intensive wear of loaded parts and nodes of a chainsaw.
• Work on a rich mixture is no less dangerous. The malfunction is manifested by an increase in the time of access to the working turnover, an increased fuel consumption, smoke from a silencer.
• There is also an intensive formation of soot in the combustion chamber, loss of mobility of piston rings.

Do I need to adjust the carburetor

Many consumers do not consider the chainsaws of an innovative technique used only by specialists. Many summer residents and ordinary households have such an instrument. After all, chainsaws are used as a convenient replacement ax, especially since manufacturers offer customers a variety of units and at a very affordable price.

Since the design of the device is quite simple, if desired, everyone will be able to figure out why the chainsaws are not started, taking into account the advice of experts.

Before proceeding to consider the main issue, you should figure out how to adjust the carburetor. the main locking device of the chainsaws. If we consider the adjustment on the popular model STIHL 180, then such an event is simply impossible to implement.

In this model, the carburetor is equipped with a captive single screw, that is, a clockwork can be considered as a screw used to configure idle. The nozzle provided in the factory device is motionless and fully equipped with a load. In simple words, we can say that the factory tuning of the carburetor helps to bring the air-fuel mixture directly to the engine during operation of the unit.

Recommendations for eliminating faults

In the first case, the problem is solved by bringing into good condition of the air intake device. It is recommended to blow out the resource of the paper filter in the backflow of air, at best replace. Methods of cleaning filters of other types are indicated in the attached operating manuals.

• Carburetor adjustment is carried out at the engine heated to the operating temperature. The power unit is displayed to the optimal mode by rotating the adjustment screws of the quantity and quality of the mixture. The success of the work is determined by knowledge of the design of the fuel system, the interaction of all components.
• In particular, the increased difficulty in adjusting carburetors with built.in compensators and other automatic control elements. Such equipment is configured using special equipment, which is equipped with service-repair centers.

If the engine cannot be tuned, the cause of excess fuel in the emulsion may be a violation of the valve tightness or freezing of the float of the carburetor itself.

The final result of the work performed:

• fast speed set;
• stable work in idle mode;
• restoration of traction parameters;
• lack of increased smoke and detonation noise.

Criteria for the selection and operation of spark plugs

The easiest indicator of the quality of the mixture is the faory insulator of the central electrode of the spark plug. Any shade of brown color indicates the normal quality of the mixture, a white or smoked insulator indicates a poor or re.enriched composition of the emulsion.

The viburnum of the operated candle must meet the stated requirements.

• The cause of sinking can be the so.called “cold” candle, which can be visually determined by a short insulator. Interruptions in sparking are possible with improper adjustment of the clearance or due to natural burnout of contacts.
• The recommended distance between the contacts of the candle is indicated in the instructions, in the absence of information, you can focus on the standard value of 0.7-1 mm. With a smaller gap, the efficiency of fire.air emulsion is reduced, with increased, interruptions in sparking are possible.
• It is not recommended to burn a damp or oiled candle on an open flame due to the risk of cracking and premature failure.

Crossing the mixture in the combustion chamber of a technically serviceable chainsaw is eliminated by blowing the engine. To do this, just turn out the candle and handle the crankshaft several times with a hand starter.

serious causes of malfunction

If, after a thorough inspection of the base nodes of the trimmer for grass, the cause of the device malfunction was never found, then you need to carefully inspect the engine and carburetor. In this case, three key problems can be distinguished at once, which are most often found:

• Natural wear of the installed carburetor laying. The only logical exit from this situation is to replace a faulty part.
• Cluster of garbage and soil in jettles or channels. For cleaning, you can use exclusively factory flushing or a regular stream of compressed air from the compressor. It is forbidden to use wire and sewing needles, since one incorrect movement can seriously damage the passing section.
• Loss of the previous tightness. For a thorough check of this indicator, a classic household tonometer should be used, after installing a suitable pressure gauge. It is necessary to monitor the indicators: if any fluctuations were not recorded, then everything is fine, but when the pressure gradually drops, then some part in the carburetor failed.

If the carburetor used is serviceable, then the gasoline trimmer for the grass is not started due to the fact that the piston group was out of order. If during the inspection, characteristic chips, curvature or scratches were found, then the detail must be replaced. Experts recommend replacing piston rings. If a small backlash occurs when swaying a mounted connecting rod, then rings are subject to replacement, but this procedure is best entrusted to professionals.

Risks of use of poor.quality fuel

The composition of various low.octane gasolines and fuel surrogates contain alcohol components, for the complete combustion of which it takes more time. The economy of the use of such fuel is dubious, since there are a number of factors confirming inefficient work and forced engine wear.

Smalling the candle is facilitated by the use of heat-resistant motor oils for 4-stroke engines, a large wear of compression rings or the entire piston group as a whole.

DIY Carburetor Repair with your own hands

What remains to make our client of a malfunction of the chainsaws into two main groups: problems of the motor with different nodes and systems (ignition, fuel supply system, cylinder-piston group, exhaust system) and malfunctions of other nodes (circuit brake, lubrication system, clutch clutch, clutch, clutch, clutch system Shina, etc.).

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

When repairing a chainsaw yourself, it is necessary to act as a way of exclusion. To inspect alternately what remains to make our client likely prerequisites for the malfunction, starting from the development of those whose verification and elimination of which takes the least time (about the device and operation of a two.stroke engine, see here).

All types of motor problems, the above, are variations to be caused by malfunctions that allows accounting (software) of the ignition. Therefore, when they appear, it makes sense to start searching for a malfunction from a candle. This is much more justified that the state of the latter gives useful information about the work of the fuel accounting system. What will be needed, if there is a problem, you need to unscrew the candle and look around it.

The wire is disconnected, and the candle is wrapped in a special key.

If the candle is dry, this means that the inconsistent is most likely not in the ignition system, in not admission to the fuel consistency cylinder. You can wrap the candle back and take for the fuel system. If the candle is very sprayed with the fuel consistency, it means its excess. This is carried out from the dilution of the carburetor or violation of the launch rules. The candle is wiped and dried, drain the cylinder, blocked the supply of fuel and working as a starter. To ventilate the combustion chamber and remove excess fuel. Then set the candle to the destination and repeat the start.

Carburetor Carburetor Cleaning

The presence of most dark soil also reads defects in the fuel system.

You will like the ratio between oil and gasoline in the consistency, the carburetor is not adjusted or poor oil is used. The candle is washed in gasoline, cleaned with a needle as it is also called an awl from the carbon fiber, clean the electrodes with a small skin and installed to the district.

In these numerous these cases, you need to check the gap between the electrodes of the candle. Based on her brand, he should be in the interval of 0.5-0.65 mm. It is necessary to check the sealing of the candle. With its worn out or damage, you will like the density of the combustion chamber more, which leads to a decrease in compression in the cylinder and dilemmas during the operation of the motor.

Even if for which the design of checking the candle is intended, there are huge reasons to believe that the malfunction is in the fuel system, it is necessary to check the candle for the presence of a spark. At least for the possibility of not not not not not not of fact, that with this what remains to make our client in order. For this purpose to you:

• put on the spark plug on the candle;
• With the help of pliers with insulated handles, a thread is applied in other words of the nut of the candle to the cylinder;
• pull the label handle and look. there are a spark or it is not.

Read how to saw long boards on a sawing machine

In the absence of a spark, you just need to change the candle. If the latest candle does not have a spark, it is necessary to check the condition of the high.voltage wire for the presence of a cliff and contact with the candle.

The reason for the lack of a spark may be a faulty ignition module or a violation of the gap between it and the magneto pipeline of the flywheel. It should equal 0.four.5 mm. The disruption of the clearance becomes especially possible if before this was the disassembly of the saw with the filming of the flywheel and the ignition module. The gap is exhibited using a gasket with a width of 0.four.5 mm placed between the boss of the flywheel and the ignition module. A faulty ignition module must be replaced.

Having checked the ignition system by such a macar, without finding a malfunction, you can run to the fuel consistency supply system.

If the candles have established that the fuel does not enter the cylinder, it is necessary to see our client like the likely prerequisites for this. You will like this more:

• not the intake of fuel from the tank due to the clogged hole in its lid (sapuna), in this case, a vacuum is created in the tank, which prevents the flow of fuel;
• pollution of the fuel filter installed in the tank;
• non.admission or missing fuel consistency from the carburetor to the cylinder.

To diagnose the 2nd first circumstances, it is enough to disconnect the fuel hose from the carburetor and look, the fuel does not flow with its use. If it flows with a working stream, a saopan and a filter is an option not to inspect, if it does not flow in other words, it flows weakly, it is that the cause of the malfunction is found. The sapun is cleaned with a needle. The fuel filter is extracted through the flood hole of the emptied fuel tank, with a wire hook, together with the absorbing hose, from which the filter is disconnected and cleaned in another way replaced by a new. Manufacturers of domestic chainsaws advise changing the fuel filter every couple of months.

The missing intake of the fuel consistency from the carburetor to the cylinder as it is also called the violation of the correct ratio of the fuel and the air mixed in the carburetor is carried out for several reasons: due to the air filter clogging, the unresolved of the carburetor, the clogging of its channels, as it is also called the mesh-filter.

You, the repair of the chainsaws cannot do without cleaning the air filter, since it is polluted quite rapidly. When this happens, the flow of air into the carburetor decreases, the fuel mixture at the output with its use comes out very enriched, which violates the normal operation of the motor. Removing a dirty filter for cleaning must be carefully so that the mud does not get into the carburetor. The filter should be cleaned as it is also called washed in water with any detergent, dried and installed back.

Chinese chainsaw is not started. Diagnostics and repair.

Carburetor’s resolution is eliminated by its adjustment. This is usually done by means of 3 screws. the largest and lowest revolutions and a blank screw. Adjustment must be carried out in a serious coordination with annotation, non.compliance with which is engaged in the breakdown of the motor. Some manufacturers of domestic saws leave only one adjusting screw (idle turnover). To exclude unnecessary intervention of inexperienced users in the carburetor work. An example of adjusting the chainsaw carburetor See the text of the article Work of a chainsaw.

What is the primary adjustment for?

In the first hours of operation, a 2-stroke character engine requires running-in, on which the quality of its further work depends. In the process of running.in, the primary adjustment of the carburetor is performed. the optimal parameters of the preparation and supply of the fuel mixture are installed.

Primary tuning of the chainsaw: Work with thin material

Most modern chainsaws go on sale as adjusted. Nevertheless, the quality of factory settings does not interfere with checking. in the end, you will have to work with the tool.

At the first launch of the chainsaw should work in gentle mode. Therefore, for several hours after the start, it is recommended not to overload the engine and cut only small branches and trunks up to 10 cm thick.

Simple rules will help to be safe from failures in the work of the carburetor of the chainsaw:

Fuel mixture proportions for a chainsaw engine

The chainsaw should start correctly, ensure the stable speed of rotation of the stars and the smoothness of the growth/decline of power. When operating the engine, there should not be extraneous knocks, cotton and noise.

Professional hand chainsaw in work

The main thing is to make sure that the fuel consumption corresponds to the power of the power, t.e. In practice, the saw should not go out, “sneeze”, smoke and work with jerks.

Why is the chainsaws badly starting

Consider each reason in more detail.

Fuel and air filter

Pollution of the main filter elements of the chainsaw, adversely affect its work.

For example, a dirty air filter will provide air supply to the carburetor in full, which will affect the quality of the fuel mixture and normal engine start. Fuel filter pollution will make it difficult, or even reduce the supply of gasoline into the carburetor and make the engine to work impossible.

Reduced compression

One of the frequent cases of the difficulty starting of the chainsaw is the wear of the CPG (cylinder.piston group).

As you know, for the normal launch of the chainsaw in its engine, compression should be present. It is necessary for the normal compression of the fuel mixture in the engine cylinder, it also affects the operation of the gasoline pump.

During the operation of the tool, the value of the compression indicator falls, and the chainsaw begins to start poorly.

The reasons for the lack of compression, or its decrease, can be natural, t.to. The engine wear out during operation. Problems can also be caused by serious breakdown, for example, Zadir CPG, or breakdown of a piston ring.

A sign of reduced compression is the weak resistance of the starter during the start. With reduced compression, a decrease in the power of the chainsaw is observed, which negatively affects its performance. The problem of replacing piston rings, or completely CPH, is eliminated.

Carburetor adjustment

Not correct adjustment of the carburetor will cause the chainsaw will not develop full power. It will be bad to start, or not start at all. The setting of the carburetor directly affects the quality of the fuel.air mixture, which is necessary for normal starting and further engine operation.

If the carburetor is improperly adjusted, the fuel with the air will be present more, or less gasoline than required, and the mixture will not be ignited even with normal sparking.

Excess gasoline in the mixture, it is customary to call overflow. Characteristic signs of overflow, it is a wet spark plug, after several unsuccessful attempts to start a chainsaw.

Spark plug

Spark plug is one of the main elements of the ignition system. On its electrodes, a spark is formed, and when this element fails, it will be difficult to start, or it is not at all possible.

The candle can completely refuse, or work with interruptions or give out a weak spark. Checking the candle is quite simple, for this you will need to unscrew it from the engine, attach to the cap of the high.voltage wire and, putting it on the cylinder, pull the starter. If the candle is in order, the spark will be powerful with a bluish tint. Weak spark with a reddish tint, a sign of a problem. A defective candle needs to be replaced.

Ignition coil

The reason that a new chainsaw is not started, or it starts poorly, may be a ignition coil. Modern chainsaws are equipped with electronic ignition coils. This part is not subject to repair, and, as a rule, in the presence of a defect, it completely changes.

Gap between the ignition coil and flywheel

An unbelievable gap between the flywheel and the contacts of the ignition coil affects the quality of sparking, which in turn is responsible for the normal start and stable engine operation.

Chinese and new chainsaws do not start what could be

The popularity of Chinese chainsaws has no boundaries. This is due to their main advantage. affordable cost. over, often among the owners of Chinese chainsaws, questions arise about the problematic launch of the tool engine. Before you find out why the Chinese chainsaw is not started, one feature should be noted. the design of these tools is no different from German and other manufacturers. That is why the reason why the chainsaw is not started can be detected on the basis of the above algorithm.

Chinese chainsaws are very sensitive to fuel quality, therefore, in the diagnostic algorithm, fuel quality testing is in the first place. The use of poor.quality fuel leads to the fact that the tool does not work at full capacity, its service life is reduced, and difficulties arise with the launch of the launch. The instructions for the tool indicate the recommended type of gasoline and oil, which is important to use in order for the Chinese chainsaw to work for a long time and at full power.

If you bought a new chainsaw, and it will not start, then here you need to start the search for faults with the return of the tool to the store. Make sure that you start the tool engine correctly, and if you cannot achieve a positive result, you need to return the tool to the store under warranty.
