  4. Next, the combination switch must be set to the permissible position, labeled “Cold Start”;
  5. Then the Stihl saw needs to be grasped with both hands, and slowly pull the plastic lever of the built-in factory starter until it feels resistance. Immediately after this, it is necessary to quickly pull the starter lever towards you several times until the engine starts and stalls;
  6. At the end, you need to pull the inertial brake lever towards you, and start working with the tool.

By adhering to this procedure, the owner of the model Stihl MS 180 will be able to protect its main working bodies from increased wear and significantly extend their service life.

The proportion of oil and gasoline for chainsaws Stihl 180.

It is important to observe the ratio of gasoline and used engine oil to avoid premature failure of the carburetor, factory cylinder-piston group, and other important components of the garden tool.
First of all, you need to learn the company management. The instruction manual will indicate the correct fuel ratio, suitable gasoline, as well as the right oil to lubricate the chainsaw chain Stihl 180.
According to the management of the German Stihl saw, for refueling it is necessary to use only gasoline of a grade not lower than AI-92, as well as branded oil for 2-stroke engines of Stihl. The ratio of fuel to oil should be 1:40, that is, 25 ml should be added to 1 liter of gasoline. The fuel mixture will need to be stirred thoroughly by shaking the container several times. After that, the contents of the vessel will need to fill in the fuel tank.

Running in of the Stihl MS 180 chiansaw

After preliminary preparation of the necessary mixture of fuel and used motor oil, it is necessary to proceed to the planned running-in of the new Stihl tool. This procedure plays a huge role because, during its execution, all the working mechanisms of the tool fall into place and closely rub into each other.

To run in a Stihl 180 chainsaw, you need to perform the following steps alternately:

  1. First you need to fill the fuel mixture and a suitable oil for lubricating the saw chain. For this purpose, separate tanks are provided in the saw device;
  2. Next, you must turn off the factory inertia brake. this will prevent the plastic case from melting in the area of ​​the clutch;
  3. After that, you need to turn on the chainsaw and let it work at idle for about 15–20 minutes;
  4. Then you need to go to sawing thin branches. Gradually, the thickness of the branches must be increased.

During the run-in of the Stihl MS 180 saw used, it is important not to allow the engine to operate at the highest possible speed, as this can lead to the formation of burrs on the surface of the cylinder. Also in the process of running it is not recommended to use motor-drills, bark beetles and other common nozzles for chainsaws.

Adjusting the carburetor chainsaw Stihl 180 do it yourself.

Factory carburetor chain saw brand Stihl plays a leading role in the device model. During her work, he is responsible for mixing the fuel mixture with air and its supply to the engine cylinder.
Before adjusting the carburetor, you need to remove the plastic tool case and clean the internal parts of the saw from dust and soot. Under the housing cover, there are three adjustment screws. The first two screws — marked with the letters H and L — are needed to adjust the proportion of fuel and air, which is determined by the opening level of the throttle valve. During the loosening of the screws, the fuel mixture is enriched with air, because of which the engine speed drops. If the screws are tightened, the amount of air used in the fuel decreases, which leads to an increase in the engine rotation speed.
A screw marked H is required for setting the maximum engine speed. Screw L is responsible for adjusting the required minimum operating speed of the motor. The third screw, marked S, is needed to fine-tune the idle working speed of the engine of the Stihl MS 180 chainsaw.
Setting the carburetor saws German brand consists of two stages. The first stage is basic, or, as it is also called, factory. It is made only when the engine is off the garden tool. The second stage is final. The heated engine is required to perform it. To know the extent to which the adjusting bolts are turned, you need to read the saw instructions in advance. It contains the exact configuration scheme for each screw. Arbitrary adjustment of the bolts without knowing their exact end position can damage the chainsaw motor.
During the basic carburetor setting with the engine turned off, the screws H and L must be alternately slowly turned in the direction of the clock until it stops. Then each of them must be turned out two full turns in the opposite direction.

The final carburetor setting is performed in this order:

  1. First you need to start the engine of the chainsaw and let it work for 5 minutes until it is fully heated;
  2. Next, you will need to start alternately turning the screw H in different directions until you find the maximum engine speed at idle;
  3. Then the screw with the marking L must be turned 1/4 of a turn against the hands of the clock;
  4. If, after the performed actions, the chain on the tire began to rotate, then the screw S will need to be turned counter-clockwise. It is necessary to finish the manipulations with the screws S only when the saw chain is completely stopped;
  5. Next, you need to adjust the maximum engine speed using a manual tachometer connected to the motor.

After setting the carburetor will need to check the engine. To do this, with the tool turned on, it is necessary to pull the gas trigger several times sharply. If, with a quick pull of the trigger, the motor dramatically rises, and when it is released, it loses them, then the adjustment of the factory carburetor was made correctly.

What to do if floods a candle on a Stihl 180 chainsaw?

With frequent use of the tool, one of its fuel tubes may be cut off, which will cause fuel to get on the candle and other parts of the saw.
In the event of a broken fuel tube or a hole in it, the tool holder will need to remove the damaged hose and replace it with a new one. In this case, the place of the joint of the new tube with the factory fitting must be carefully treated with a sealant.

There is no oil on the chain chainsaw Stihl 180.

One of the leading causes of the problem in which the oil is not supplied is the breakdown of the pump feeding the oil to the saw headset. To eliminate the problem, you will need to remove the tire and chain, as well as remove the side protective plastic cover. After that, the place under the body will need to be cleaned and replaced with a pump.
If the chain is not lubricated, the cause of the failure may also be the breakage of one or more oil tubes. In this case, you will need to remove the hoses and replace them.

Saw Stihl 180 stalls at idle. how to solve the problem?

In this case, the cause of the sudden breakdown should be sought in the instrument ignition system. Often with mechanical shocks, the gap between the flywheel and the factory ignition coil is broken, which leads to a breakdown of the entire system. In this case, you will need to disassemble the tool and check the distance between the elements.
To adjust the clearance, you need to loosen the flywheel mount. After that, between the flywheel and the ignition coil will need to insert a template, and begin to screw the bolts back. As soon as the flywheel comes into contact with the template, the bolting should be stopped.

Chainsaw Stihl MS 180 bad wind up on the cold.

First, you need to make sure that the spark plug is not flooded. If it has formed a thick layer of soot, then you will need to inspect the fuel system. She could lose her tightness as a result of a broken hose or a failed fuel pump.
If everything is all right with the candles, then you will need to check the air filter. As a result of intensive use of the chainsaw, it could become clogged or become unusable. In this case, cleaning the filter or replacing it will help.
The third element that could fail is one or more compression rings. They are not amenable to recovery, so they will need to be replaced.
