Stihl Petrol Cutter Won’T Start

The petrol cutter does not start, or starts, but stalls. What is the reason?

The gasoline cutter won’t start after winter

In such cases, the unit must be serviced. Remove the fuel system, including filters (air, fuel), disassemble the carburetor, clean and rinse each unit. Blow out the filters with air. Pay attention to fuel quality and octane number.

It should be borne in mind that products of such well-known companies as STIHL, Husgvarna and other brands will not run on cheap gasoline with a low octane number.
Suitable fuel for them is from the AI ​​92 brand and above from car refueling stations and then from well-recommended ones, since there is also bad gasoline at refueling stations. The use of high-octane and high-quality gasoline will determine how long the brushcutter will be used and how long it will last.

It is necessary to take into account one more fact that with a long storage of a diluted fuel mixture, its working qualities fall, which also leads to consequences in which the petrol cutter will not start. Therefore, it should be diluted in portions, that is, the amount of the mixture that is produced at a time.
The operating instructions clearly describe and explain the mixing ratio of gasoline and oil. Strict observance of the correct proportions will at least save you from several questions about why the petrol cutter will not start and what to do in such cases.

The benzokos does not start on a cold

When starting a cold engine, it is not recommended to press the gas. Tilting the brushcutter so that the air filter is on top, press the fuel suction button 5-6 times, set the function switch lever to the start position, pull the starter cord several times until the engine starts. After a few seconds of running the motor, turn off the starting system.

The benzokos starts up and stalls. What to do?

1. There is a spark, and everything seems to be normal, but the petrol cutter will not start, in such cases, you should check the air access valve to the fuel tank. A clogged valve leads to the creation of a vacuum in the tank, in which the carburetor does not receive enough gasoline, so the petrol brush will start, but then stall. To exclude this reason, you need to clean the valve and try to start a petrol cutter with a tank cap that is not completely twisted.
2. If the brushcutter does not start at the same time, you should remove and clean the fuel filter, as well as check all the carburetor parts, and then try to start. The petrol cutter will not start again, the air filter is disconnected, try to start without it, if the mower starts up, the reason is in the air filter, replace it.

The petrol cutter will not start, the spark is gone

The loss of a spark entails checking the contacts and the correctness of the gap between them, the conducting wires to the candle and the candle itself.
The way to check the spark is to unscrew the candle, connect a wire to it, put the candle sideways to the engine casing and pull the starter several times as if starting a petrol cutter, while looking at the coal and the contact of the candle, a spark should run between them.
If there is no spark, take a new candle, follow the same procedure, if the spark cannot be traced, then there is a problem in the wire or contacts, it is better to replace them.

The petrol cutter will not start or will start, but stalls. What is the reason?

To understand this, you need to know the principle of operation of the unit as a whole. It also happens that, just bought, a new saw does not start, and it starts running around the service centers, in such cases it is recommended:

Carefully read the instruction manual;
to study in detail the method of the first start-up and running-in of petrol cutters;
try to understand how the product works;
how gasoline is pumped up and so on.

Reasons for malfunction of petrol cutters:

  • The quality of gasoline is poor;
  • Incorrect proportion of gasoline and oil;
  • Clogging of the fine filter;
  • The spark was gone.

The benzokos does not start when hot

If the brushcutter was recently in operation and has not yet had time to cool down but does not want to start, press the gas trigger, pull the starter cord sharply several times until the engine starts and only then the gas trigger is released. If enough time has passed and the brushcutter has managed to cool down, then it is necessary to start it as if it were cold.

Stihl 180 chainsaw does not start: main reasons

Today, many manufacturers are engaged in the production of units for agricultural and construction work, among which the most demanded is the equipment manufactured by Stihl. The high level of quality is not the only reason why the products of this manufacturer are popular in the market. This was also facilitated by the democratic price and optimal power that the models of this brand have.

It seems that many had to use a chainsaw of a similar brand. And not just use it, but regularly perform a wide variety of work and make sure of the high performance characteristics of this tool. Such a proliferation of these products is no coincidence, given that, in addition to power, this instrument stands out for its graceful design. However, one must remember that this is still a technique for which the resource of work is limited. Therefore, each owner of such a unit at some point is faced with the need for repair. Next, we will talk about the features of repairing the Stihl 180 chainsaw.

Stihl Petrol Cutter Won'T Start

Other malfunctions

  • For many owners, a question regarding correct idle after emptying fuel from petrol tanks. According to experts, you shouldn’t worry too much about this. However, if you have to deal with a similar problem often, then it is enough to manipulate the carburetor by reducing the engine speed in order to restore the normal operation of the tool.
  • In some cases, the owner may need to clean the muffler, as this part may be the cause of the malfunction. This operation is quite simple. It must be remembered that many owners are faced with problematic chainsaw operation. Due to faulty carburetor.
  • Although in some cases it can be quite simple to fix the malfunction, it is preferable if specialists will repair this equipment. After all, not each of us has the necessary knowledge and skills, and this is fraught with the fact that during self-elimination of a malfunction there is a risk of completely disabling the tool.

Clockwork device

As with other saws, the carburetor acts as the main starting device. Considering in more detail the carburetor with which the Stihl 180 chainsaw is equipped, it should be noted that it has a single tuning screw. In other words, it is a kind of idle speed adjustment screw. In this case, the jet, which has a full load, is stationary all the time.

In other words, the regulation is not applicable to it. In turn, there is no way to influence the full load in any way. You also need to pay attention to the factory settings, due to which the supply of the air-fuel mixture is carried out directly to the engine. Over, this principle is maintained regardless of the operating conditions of the tool.

Saw won’t start: reasons and solutions

  • Speaking of the saw 180, it must be said that this tool has many advantages. At the same time, this unit is not without its drawbacks. Attention will be paid to them.
  • It is a common situation that many owners find themselves in when the Stihl chainsaw does not start and floods a candle. This is usually attributed to the formation of a leak in the oil used to lubricate the chain. The same happens for the reason that over time, the area where the hose of the oil pump and the oil tank is joined loses its former tightness.
  • In principle, this problem is solvable, however, in order to do everything correctly, you need to take into account the design of the chainsaw in question. By itself, this process provides for certain nuances, first of all, it is necessary to disassemble the unit, and without this it will be impossible to get to the required place.
  • For many owners of this saw, the question is, why does the Stihl 180 chainsaw not start? Experts give the following recommendation on this matter: the first thing to do for those who have encountered a similar problem is to open and then close the lid located on the gas tank. There is another solution: take out the candle and let it dry. You can also create the effect of artificial ventilation for the combustion chamber. Most often, these recommendations are enough to bring the device back to working condition. However, this does not always help to restore the operation of the Stihl chainsaw.
  • If there is a spark, but attempts to start the chainsaw do not lead to anything, then in this case you need check petrol supply, air filter, and then make sure the spark plug is working. Such manipulations must be done for the reason that most often such malfunctions are caused by contamination of the breather. And if a plug forms in it, then, naturally, a vacuum environment will be created in the gas tank, due to which the fuel will not flow. A similar problem can be solved quite simply, for which it is enough to remove the dirt using a needle.
  • Some owners face this problem when the saw itself starts, but immediately starts to stall. Look for the cause of the saw not starting in the carburetor. Most likely, he managed to clog up and therefore does not allow the tool to work correctly.
  • To make sure that the breather is not the cause of the malfunction, and it is in working order, you must first disconnect the fuel hose from the carburetor, then find out if there is a fuel leak.
  • Keep in mind that it is natural for a properly functioning chainsaw to have dense and stable stream of gasoline. In addition, it is often possible to observe a situation when the Stihl 180 chainsaw does not start hot and immediately stalls at the same moment or after a while. Usually a similar malfunction is associated with a muffler. Most likely, it has accumulated a lot of deposits associated with long-term use of the tool, which is usually accompanied by the formation of exhaust.
  • At the same time, the saw may stop starting if the tool chain is poorly lubricated. This can be facilitated by channels with a plug, or the reason should be sought in an oil pipe that has a leak.
  • A serious problem can be leaks in the connecting pipes or at the installation site of the oil pump fittings.
  • There are cases when the Stihl 180 chainsaw begins to stall due to a failed cylinder. To make sure whether this is really so, it is enough to conduct an inspection. If, as a result of the examination, you find irregularities and chips, then this is a clear sign of breakage.

There is no spark on the Stihl 180 chainsaw

The main malfunction due to which the stihl ms 180 chainsaw does not start may be the absence of a spark between the electrodes on the spark plug. Symptoms of this malfunction can be detected by unscrewing the plug and inspecting. Having discovered during inspection that the spark plug is wet, it is necessary to start looking for the reason for the absence of a spark on the spark plug.

Fuel does not flow

This type of malfunction, like the others, has its own characteristic symptom. It consists in the fact that the working spark plug, on which there is a spark, will be absolutely dry. You can check suspicions of a lack of fuel supply using the following algorithm.

Defective spark plug

The first thing to do is to check the performance of the candle.

This is pretty easy to do. The candle is inserted into the cap of the high-voltage wire and pressed against the engine cylinder, after which the starter moves several times, if there is no spark between the spark plug electrodes, then it is faulty or the ignition module is faulty.

In order to find out for sure that the problem is in the spark plug, you need to check the known good one in the same way. If, as a result of the check, a spark appears, then the problem has been found and to eliminate the malfunction we replace the spark plug with a new one.

Defective crankshaft bearings

With a defect in the crankshaft bearings, a slight backlash is observed on it. You can check for backlash by shaking the flywheel of the Stihl 180 chainsaw from side to side. If there is a backlash, then, under the action of its magnets, the flywheel is attracted to the contacts of the ignition coil, since the backlash on the bearings allows it to do this and as a result the spark disappears.

Engine Purge Algorithm

Important: never purge the engine with the ignition on and near open flames.

  • Unscrew the candle;
  • Turn the Stihl 180 chainsaw upside down and drain off excess fuel;
  • In the inverted state, pull the chainsaw starter several times (thus, under the influence of compression, excess fuel will be removed from the cylinder);
  • Install the plug and the cap of the high-voltage wire in place;
  • Set the engine control lever to the hot start position;
  • Pull the starter motor several times and start the engine.

If everything is in order with the Stihl chainsaw and the cold start algorithm was simply violated, then after blowing it should start. Otherwise, the fault must be sought in the carburetor.

There is no clearance between the flywheel and the ignition module

In some cases, the absence of a spark on the spark plug is due to an incorrect gap between the contacts of the ignition module or the flywheel. It may be larger, or it may not be at all, and then scratches will be observed on the surface of the flywheel as a result of contact with the contacts of the coil.

You can check and set the gap without having a special tool. To do this, you will need to remove the starter, loosen the two screws securing the coil and lay a plate cut from a plastic bottle between the flywheel contacts and the ignition module, tighten the module fastening screws.

If, after such adjustment of the gaps, a spark appears, everything is in order, you can continue to work with the Stihl 180 chainsaw, if not, you need to re-inspect and check whether the flywheel touches the coil contacts again. Suppose, as a result of the check, it was found that after adjusting the gap, it was gone again. So the reason is most likely in the crankshaft bearings.

Briefly about the main

This model is the pride of the German manufacturer and is a direct tool intended for minor level work. It can be used no more than twenty hours a month. This excellent device will easily help you cope with the care of your garden, prepare firewood for the winter period of time (see how to cut down a tree), make cleared areas, and will also be an indispensable assistant in other areas, let’s say, simple manipulations.

We can say that these are a mini-model of chainsaws, since it has a small weighing about 3.9 kg, it does not have a large mass of both oil and fuel tanks. The manufacturer has equipped this device with a two-stroke engine with ample power for light work.

Over, it is quite quiet since during operation the noise level does not exceed 98 dB. So to better understand the level of loudness itself, just compare its noise with spoken speech, which has an indicator of 76 dB.

The power of this model is equal to 2.6 W. It’s worth noting that this is a fairly significant level of strength, given that it is not a professional chainsaw. The oil tank has a volume of only 0.145 liters, and the fuel tank 0.25 liters. The tire has a dimension of 350 mm and a pitch of 0.325 inches.

It is important that if you even found the very cause of the instrument malfunction, this does not mean at all that you can eliminate it yourself. Since there are such breakdowns that can only be corrected by a specialist. If you have carried out direct manipulation regarding checking and changing the quality of the oil (see oil for the Stihl chainsaw), but, nevertheless, the chainsaw still refuses to start, in this case, you need to continue searching.

But if you fully performed all the manipulations prescribed above and did not miss a single nuance, but nevertheless the instrument has not yet been corrected, then in this case the problem lies in the group, which is called cylinder. But if you still could not bring your iron friend back to life, then simply take the chainsaw to a service center where your device will be repaired. Also, do not forget to take care of the engine to find out the ratio of gasoline and oil for chainsaws, read this article.

How to eliminate the reasons why the device does not start

Shtil chainsaw won’t start: reasons and solutions

First of all, it is worth noting the fact that the 180 chainsaw of this manufacturer is one of his best creations, but it also has its drawbacks. Actually, about which we will now talk.

  • A fairly common problem is that the Stihl 180 chainsaw does not start and floods a candle. The reason for this is that the oil used to lubricate the chain starts to leak. Since time is merciless and simply breaks the tightness exactly in the place where the hose from the oil pump and the oil tank is actually connected. Naturally, this problem can be solved, but, given the design of this chainsaw, it will not be so easy to do this, since you simply have to completely disassemble the device in order, as they say, to get to the right place. It can be seen more clearly: https: //www.Youtube.com/watch? V = UOsYJBOVuwg
  • Many are worried about this question: why does the Stihl 180 chainsaw not start? If you believe the experts, then in such a situation, you first need to open, and then close the lid that is on the gas tank. Or get out and dry the candle. Or try to ventilate the combustion chamber. In most cases, this kind of manipulation is enough to make the device work. But there are times when the Stihl chainsaw does not start, but there is a spark.
  • In the above case, you need to make a direct checking the gas supply, air filter and the direct performance of the candle. Since the basis of this kind of breakdown is the breather, namely its pollution. Because when it is completely clogged, a kind of vacuum arises in the gas tank itself, which simply interferes with the fuel supply process. This issue is not difficult to solve, since all you need to do is clean it using a needle.
  • There are also situations when the device, in principle started up, but immediately died out.

In order to exclude the saloon from damaged objects, it is necessary first of all to disconnect the fuel hose from the carburetor itself and actually check if fuel is leaking from it.

  • You must remember that in the process of using your chainsaw correctly gasoline should flow out in a dense and stable stream. Also, it is not uncommon for the Stihl 180 chainsaw to not start up hot and actually stall after switching on or holds power for a rather short time. In this case, the problem of breakdown lies precisely in the muffler, which can be simply clogged with any deposits that arise through the operation of the device , and which settle during the exhaust process.
  • Also, a fairly common cause of tool malfunction is insufficient lubrication of the device chain itself. The reason for this may be the channels that are simply clogged, or the reason is in the oil line that is leaking.
  • Connecting pipes or the connections themselves in the area of ​​the oil pump fittings can also leak.
  • It happens that the Stihl 180 chainsaw does not start well due to cylinder that can be broken. But to determine its condition, a visual inspection is enough. But if even there you find the formation of irregularities and chips, then you can be sure that you have found the cause of the breakdown.
  • If through verification you find that malfunction in the candle, then you simply need to turn it out, and then dry it directly. But it is worth noting that in no case should you pierce it, since you will simply spoil the part, and it will be unusable. You also need to drain excess fuel from it through a special hole.

Over, it may be that the expiration date of your candle has simply passed, in which case it is necessary to replace it. Therefore, it is a great advice that it is best to always have a new candle in stock or, best of all, a set. Then you can replace it at any time and actually understand whether it was the direct cause of the device breakdown. Over, a weak contact can also be the cause of a breakdown, which actually connects the high-voltage wire and the end of the candle. Also, the cause may be a breakdown of the ignition unit. It is worth noting the fact that in order to eliminate this kind of problem, it is necessary to replace the unit itself, since it cannot be repaired.

  • Equally important is the concern of the owners of this model regarding systematic idling after the actual gasoline first tanks are empty. But if experts in this field are to be believed, they argue that this kind of situation does not pose any problem. But still, if this kind of process is repeated quite often, then you need to simply reduce the engine speed by using the carburetor screw.
  • In addition, you can personally produce cleaning the muffler itself, since the cause of the malfunction may be in it. This manipulation is not difficult. A fairly common phenomenon of poor-quality tool operation is the carburetor.

    Stihl saw winding device

    The basis of a plant of this kind of model, as well as all other chainsaws, is a carburetor. But since we are talking today about the Stihl 180 chainsaw, we will not deviate from the topic. So. The carburetor in this model has a single adjusting screw, that is, it is a kind of idle stroke adjustment screw. While the fully loaded jet is stationary.

    In simple terms, we can say that it simply cannot be adjusted (see here), while the full load setting simply cannot be changed. It is important that the carburetor itself at the factory was configured in such a way that regardless of the actual conditions under which the chainsaw is operated directly, the air-fuel mixture is supplied to the engine itself.

    Stihl-180 does not start: reasons and remedies, why the chainsaw floods the candle, gasoline does not flow to the cold

    Today the manufacturer Stihl occupies a leading position among other companies that produce equipment for agricultural and construction work. The products of this manufacturer are famous not only for their high level of quality, but also for the optimal pricing policy and power of its models. Probably, it is quite difficult to meet a person who does not have a chainsaw of this brand. This is one of the most famous world companies. But the fact that out of ten possible, six people definitely have them. This is not surprising, since Stihl chainsaws deliver power as well as graceful design. But unfortunately, such giants of technology sometimes fail and require some kind of repair. Let’s talk about the reasons why the Stihl chainsaw won’t start.
