One of the frequent breakdowns of the sawing device is also an open circuit in the working chain. Alas, it is not one of the dilemmas that arise when a motor accounting system is running. Usually, repairing a broken chain is reduced to replacing it with the newest.

The search for the malfunction that caused the chainsaw to fail is done in the following order. First of all, the level of gasoline in the tank is checked. If our client remains in order with the level, proceed to inspect the starting device. If the trigger does not show any signs of breakage, the spark plug should be noted.

The chainsaw does not develop speed: we test the device for malfunctions

The ignition module can be diagnosed for problems visually. For this you need:

  • turn out the candle;
  • evaluate its appearance (it should not be drenched in gasoline or contain a black coating);
  • check the distance between the coil and the magnets (up to 0.2 mm);
  • if necessary, examine the spark plug unit for spark supply using a working mains wire.

If, after checking, no defects were found, it is worth moving on to checking the carburetor block.

This work unit is one of the most vulnerable in modern chainsaws. New tools, which are shipped from the factory, have basic settings. for low and high speeds, which must be reset after running-in and running-in of all parts. Similar actions are performed if the saw does not develop traction corresponding to the maximum torque according to the instructions.

In this case, you need to reconfigure one of them. the “H” jack, which is responsible for the operation of the saw under load. To do this, it is enough to adjust the fuel supply with the engine running at the highest speed of rotation of the chain using a tachometer and operating instructions.

Because of what the Stihl chainsaw does not develop speed and stalls

If the chainsaw does not develop speed, then first of all it is recommended to check the fuel system. This is the first place to start, as the chainsaw engine simply does not have enough fuel mixture in order to operate at full power.

The slightest blockage in the fuel filter can lead to a lack of fuel entering the carburetor. It is very easy to get to the fuel filter, it is located in the saw’s gas tank.

When checking, you need to disconnect the hose from the filter, then blow into the filter tube. If the filter does not allow air to pass through, or it does not pass well, then it is recommended to replace it. A new fuel filter is not so expensive, about 100-150 rubles.

The second reason why a Stihl chainsaw may not develop speed is a large carbon deposit in the muffler. An abundant amount of combustion products is formed as a result of incorrect proportions of oil and gasoline. As a result, the hole in the muffler is heavily coked, which leads to a drop in the power of the chainsaw.
