Why not start the Stihl 180 chainsaw and how to solve the main causes of the breakdown?

Malfunction of the ignition coil

Stihl 180 saw won't start fills in candle

Fills the spark plug

In some cases, the Stihl 180 will start and stall or not start at all. Then we check the condition of the candle, it can be flooded. There can be two reasons for this "overflow" – improper starting of the engine on a cold one and a malfunction of the carburetor. We try to solve the problem by the following actions:

Remove the spark plug;

We turn the chainsaw over the other side and wait until excess fuel flows out;

For better confidence, we jerk the starter several times, so gasoline will surely come out of the cylinder;

We return the candle to its place, install the cap and try to start the engine again with a starter.

Stihl 180 chainsaw will not start: reasons and repairs

And the world-famous Stihl company produces a huge range of high-quality chainsaws. For household purposes and simple work, the Stihl 180 chainsaw was created, which showed excellent performance and reliability. All the best practices of the German company were used here, with a weight of 3.9 kg, the chainsaw easily performed work in the garden. She can easily cut small trees, branches, you can even prepare firewood. But any even the highest-quality equipment tends to break down, and it so happens that the Stihl 180 chainsaw does not start or start with great difficulty. We tried to collect all the reasons and methods of repairing the German Stihl 180.

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.

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.

Defective spark plug: troubleshooting methods

  • Sometimes during the check it is possible to find out that the problem lies in a faulty spark plug. In this case it is removed, then allowed to dry. Some owners may try to ignite it, but this should not be done, because otherwise this element will be damaged and after that it will only be necessary to throw it out. During troubleshooting, you will have to remove excess fuel by draining it through a special hole.
  • You also need to keep in mind that the drying time should be at least half an hour. After completing a similar operation, you can return it to its place, and then test it in action.
  • In some cases, the candle may fail due to develop your resource. Usually, when this is confirmed, the only option is to find a replacement for it. In this case, it does not hurt to have a spare candle, or even better, when you have a whole set of such elements at hand. In this case, you can always put a new plug instead of the existing one and make sure if the broken plug is the cause of the breakdown.
  • At the same time, the inability to start the chainsaw can be caused by poor contact, provided by the high voltage wire and the end of the candle. The problem with starting the chainsaw may be due to the failure of the ignition unit. In such situations, the only solution to the problem is to replace the faulty unit, since it is not repairable.

Replacing the crankshaft bearings

It is better to replace the crankshaft bearings in a specialized service, because when replacing, you will need to completely disassemble the Stihl 180 chainsaw and remove all its main components.

Without some experience or at least the skills of repairing similar chainsaws, it will not work to replace the crankshaft bearings efficiently.

So, we figured out the absence of a spark, but what to do if there is a spark, and there is no answer to the question why the Stihl 180 chainsaw does not start. The reason may be hidden in the fuel system.

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, it means that 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.

Checking the pulse from the engine crankcase

The fuel pump on the Stihl MS 180 chainsaw is installed directly in the carburetor and operates under the influence of pulses from the engine crankcase of the Stihl 180 chainsaw.

Clogging of the channel is fraught with the appearance of problems with the supply of fuel or its complete absence. To check the branch pipe, it is necessary to remove the air filter housing and the carburetor, and then check the channel for clogging with a thin metal wire.

Another reason associated with the absence of an impulse in the pipe channel is the depressurization of the engine crankcase, which results in air leakage from it and a decrease or complete cessation of its supply to the fuel pump. Depressurization results in partial or complete loss of the fuel pump’s performance. To check the tightness of the crankshaft oil seals, and indeed the crankcase of the Stihl 180 chainsaw, a special vacuum meter is used, and since it is a special-purpose tool, it is mainly available only in service centers. The question arises, what to do?

You can check the pulse supply using a syringe on the engine with the carburetor removed. You will need to draw a little oil into the syringe to lubricate the engine and squeeze it out into the impulse channel of the pipe, and then pull the starter. If the impulse does not pass, the oil will remain in the channel and you should look for the cause deeper, disassemble the engine and check the oil seals. If the oil is squeezed out of the channel, then the problem may be hidden in the fuel pump itself.

Shtil chainsaw won’t start: reasons and solutions

First of all, it is worth noting the fact that the chainsaw 180 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 that is 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.

  • 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.
