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. You need to remove 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, because of 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, and 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.

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.

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.

This model is the pride of the German manufacturer and is a direct tool intended for a minor level of 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 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.
