The Stihl chainsaw is most often used for sawing wood and construction work. Due to its versatility, the saw is used very often. The main advantage of the Calm MS 180 is its low vibration level. Like any equipment, a chainsaw can fail and require maintenance and repair, so it is important to understand what problems you may have to deal with and how to fix them.
Carburetor breakdown
The Calm Carburetor is characterized by the presence of only one screw, which is responsible for adjusting the idle speed (XX). During operation of the equipment, it is very important to pay attention to the frequency with which the screw rotates during the twentieth. You can adjust these parameters by checking the air filter and the spark damper.
The fact that the chainsaw carburetor requires adjustment is indicated by the following symptoms:
- the engine starts very poorly and switches off almost immediately;
- high fuel consumption, strong exhaust;
- The factory settings of the chainsaw are knocked down;
- improper operation of the air cleaning system;
- worn piston system.
It is worthwhile to immediately draw your attention that adjusting the carburetor of the saw is a rather complicated process. If the equipment stops working suddenly, the following actions should be performed:
- Open and close the fuel tank cap.
- Remove and dry the candle.
- Ventilate the combustion chamber.
If these steps do not work, check the air filter and the suitability of the spark plug. If the problem is in the carburetor, you should contact the service center. These works are quite complex, and it is almost impossible to do them yourself at home.
Ignition system failure
If the equipment fails, it is necessary to check the ignition system, and more specifically, the candle itself. If the candle is dry, this means that the fuel does not enter the cylinder, and therefore this is not the reason. If there are traces of the fuel mixture on the candle, you need to check the correct operation of the carburetor, as well as its adjustment. The candle must be wiped and dried, and then turn off the flow of the mixture and turn on the ignition. These steps will help remove excess fuel mixture and ventilate the combustion chamber. After that, the candle can be put in place and again try to start the saw.
If there is soot on this part, then the reason sometimes lies in the use of low-quality oil. Another reason may be incorrect proportions of the fuel mixture and oil. In this case, the candle will need to be cleaned of carbon deposits, rinsed and cleaned electrodes. It should be noted that the distance between the electrodes should not be more than 0.65 mm.
If soot is present on the candles, make sure that there is a spark. To do this, the ignition cable must be fixed on the candle, and the nut with the cylinder is fixed with pliers. After that, the starter starts. If there is no spark, we change the candle. If the replacement fails, the wiring and all connections are checked.
Another cause of failure may be a failed flywheel. To unscrew it you will need a special key, since it twists very tightly.
To block the shaft from rolling, it is necessary to remove the spark plug and put a piston stopper through the hole formed. In no case should the flywheel be blocked by a power screwdriver inserted between its ribs and the body, since the flywheel blades will not be able to withstand the load and break off.
After the piston is locked, the nut is unscrewed. When it loosens a little, its upper part will become level with the tip of the shaft, at this moment you can install a metal drift on the nut and hit it. So the flywheel jumps off the shaft, and it can be removed without much effort.
Fuel system failure (SPT)
In the process, some are faced with the fact that the fuel mixture ceases to be fed into the cylinder. This problem can occur for several reasons:
- Dirty filter. In this case, you need to remove the hose and check the flow of the fuel mixture. The filter will have to be cleaned or replaced. As a preventative measure, this part should be changed once a trimester.
- Clogged breather. You can verify this theory by disconnecting the hose. Having found a blockage, it is worth cleaning it with a thin needle.
- A small amount of fuel. It should be ensured that the fuel mixture is regularly present in the tank and is correctly fed into the engine. Disruptions in feed are possible due to a clogged filter. To avoid such problems, it is necessary to clean the filters from time to time.
It is very important for a chainsaw to choose a good quality fuel. In addition, you need to make sure that in the tank its amount corresponds to the norm.
The Stihl saw itself is quite simple equipment. However, despite this, many have difficulties with its repair, because there can be many reasons for a breakdown. Therefore, before proceeding with the repair, a diagnosis should be made and the cause identified.

- engine overheating and the appearance of thermal seizures;
- hit in the cylinder of a foreign body and the appearance of mechanical scoring;
- breakdown of the piston ring as a result of exceeding the maximum engine speed;
- breakdown of the piston skirt due to excess speed;
- the use of low-quality fuel, as a result of which the piston group of the chainsaw wears out of the intake channel in the cylinder;
- chainsaw operation Stihl with a contaminated fuel filter, resulting in a reduction in the percentage of oil in the fuel mixture;
Diagnosis of CPG is necessary if Stihl ms 180 sharply lost power or does not start, while the tool starter does not crank. If the starter turns, but the saw does not start, while there is a spark and fuel flows into the cylinder correctly, it is necessary to measure the compression in the engine.
If there is a suspicion of problems with the CPU, it is advisable to contact a service center authorized by the manufacturer, since only in it they can accurately diagnose the malfunction without a full analysis and, if necessary, carry out a quality repair.
9.5. 11 Atm. considered a normal indicator at which chainsaw Stihl it starts up regularly and gives out maximum power, if the compression is lower, there is a chance that there are scuffing on the piston-cylinder group or its wear is quite large. In any case, with reduced compression, for further diagnosis, it is necessary to completely disassemble the saw.

Replacing the piston group with a Stihl MS180 chain saw
It often happens that chainsaw Do not start, do not stun, do not develop speed. Repair can be done own hands.
The saw sometimes starts poorly, which leads to malfunctions of the starter. To identify the problem, it is necessary to remove the cover and a special screen from the carburetor, which is located behind the drum of the tool. If the contact wire is disconnected from the starter, it is fixed with a blowtorch. Sometimes the problem is oil leakage. In this case, the starter should be wiped with a rag.
Engine is unstable
Defects of the Calm 180 chainsaw, you can begin to identify yourself if the warranty has expired. Sometimes the engine runs intermittently, which may be caused by a failure of the piston group of cylinders. You can repair it yourself. To remove the cylinder from the cylinder on its head, unscrew the bolts. The master must check the piston; it should not be cleaned, scratched or scratched. If they were found, then the piston must be replaced.
Piston rings and piston provide optimum pressure in the combustion chamber. The rings must be securely attached to the piston body. If the piston inserted into the cylinder has free play during swinging, this indicates its wear. To solve the problem, it is necessary to fill the cylinder and install spare parts. But the easiest way is to replace the TsPG set.
Carburetor malfunctions
Read:
If you bought a Calm 180 chain saw, you can find and implement carburetor malfunctions and repairs. If the tool stopped, it stupefied and could not maintain power, and also did not work at idle, then the carburetor can cause damage. In the process, often dirt, dust or sawdust is often clogged. You can remove the problem by cleaning it.
Faults of the Calm 180 carburetor chainsaw are resolved after preparing some tools, including:
The brush can be used to clean dust and dirt. Then remove the cover and filter. Two nuts of the air filter are unscrewed, which will lead to the removal of the air intake housing. Now you can see the carburetor. When lowering the shutter, it is necessary to remove the accelerator lever.
To move the carburetor from its place, it is necessary to remove the suction lever and close it. Now remove the engine stop wire and pull it toward you. The plastic lever is removed, the wire is attached to it. The carburetor at this point can be released and removed for cleaning. To do this, it is best to use a compressor, but if it is not available, this can be done using pure gasoline.
Given the basic malfunctions of the 180 chain saw, you should know that you must not forget about the fuel filter. It is removed and the fuel hose is purged. Now you can put everything in reverse order. If, after assembling the carburetor, the tool is still tightly twisted and the muffler produces smoke, then the spring under the needle lever has been lost. Due to its absence, the needle does not block the fuel supply. As a result, the candle is filled with gasoline. To fix this problem, you need to find the spring and install it in place.
Specialist advice
When repairing a carburetor, you should remember that this is a complex assembly consisting of rings and many parts. This means that cleaning and repairs must be carried out with the utmost care. If the tool stalls or fails to start, then in addition to the carburetor, spark plugs must be checked. If they are faulty, they are twisted and dried.
Additional fuel can be drained through a special hole. Faults of the Calm 180 chainsaw and their elimination are partially described in the instructions. After reading the article, you can understand that the candles must be dried for at least half an hour, after which the candle can be put in place by starting the device.
