Proportion of oil and gasoline for Stihl 180 chainsaw

In order to prevent premature failure of the carburetor, factory cylinder-piston group and other important components of a garden tool, it is important to observe the ratio of gasoline to engine oil used.

First of all, you need to study the corporate manual. The instruction manual will indicate the correct fuel proportion, suitable gasoline, as well as suitable oil for the lubrication of the Stihl 180 chainsaw chain.

According to the manual of the German Stihl saw, for its refueling it is necessary to use only gasoline of a brand not lower than AI-92, as well as branded oil for 2-stroke engines 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 thoroughly mixed by shaking the container several times. After that, the contents of the vessel will need to be poured into the fuel tank.

Running chainsaw Stihl МС 180

After preliminary preparation of the necessary mixture of fuel and used engine oil, you need to proceed to the planned run-in of the new Stihl tool. This procedure plays a huge role, since during its execution all the working mechanisms of the tool fall into place and closely rub against each other.

To run around the Stihl 180 chainsaw, you need to take the following steps in turn:

  1. First you need to fill in the fuel mixture and a suitable oil to lubricate the saw chain. For this, separate tanks are provided in the saw device;
  2. Next, you need to turn off the factory inertial brake. This will prevent the plastic body from melting in the adhesion area;
  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 proceed to sawing thin branches. Gradually, the thickness of the branches needs to be increased.

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

Do-it-yourself carburetor adjustment for the Stihl 180 chainsaw

The factory carburetor of the Stihl brand chain saw plays one of the leading roles in the device of the model. During her work, he is responsible for mixing the fuel mixture with air and supplying it to the engine cylinder.

Before adjusting the carburetor, you will need to remove the plastic tool body and clean the inside of the saw from dust and carbon deposits. Under the housing cover there are 3 adjusting screws. The first 2 screws. Marked with the letters H and L. They are needed to adjust the proportion of fuel and air, which determines the level of opening of the throttle valve. During the loosening of the propellers, the fuel mixture is enriched with air, because of which the engine speed drops. If you tighten the screws, the amount of air used in the fuel decreases, which leads to an increase in the engine speed.

A screw marked H is required to set the maximum engine speed. Screw L is responsible for adjusting the required minimum operating revolutions of the motor. The third screw, marked S, is needed to fine tune the working idle of the internal combustion engine of the Stihl MS 180 chainsaw.

Setting the carburetor saws of the German brand consists of two stages. The first stage is the basic, or, as it is also called, factory. It can only be done with the engine of the garden tool turned off. The second stage is the final one. For its implementation, a warmed-up motor is required. To know the extent to which adjusting bolts are turned, you need to read the saw instructions in advance. It indicates the exact configuration for each individual screw. Arbitrary adjustment of the bolts without knowing their exact end position can damage the chainsaw motor.

During the basic carburettor setting with the cold engine turned off, the H and L screws must be turned slowly alternately in the direction of the clock hand until they stop. Then each of them needs to be turned out 2 full turns in the opposite direction.

The final carburetor adjustment is performed in the following order:

  1. First, you need to start the chainsaw motor and let it run for 5 minutes until it is fully warmed up;
  2. Next, you will need to start turning the screw H in different directions one by one until the maximum engine speeds are found at idle;
  3. Then the screw marked L must be turned 1/4 turn counterclockwise;
  4. If, after completing the steps, the chain on the tire starts to rotate, then screw S will need to be turned counterclockwise. Manipulation of the S screws is only necessary when the saw chain stops completely;
  5. Next, you need to configure the maximum engine speed using a manual tachometer connected to the motor.

After adjusting the carburetor, you will need to check the engine. To do this, on the switched on tool, you must sharply press the trigger of gas several times. If, with a quick pull of the trigger, the motor abruptly picks up speed, and when it is released, it loses them, then the factory carburetor has been adjusted correctly.

Stihl 180 chainsaws. Malfunctions and repairs

The simplicity of the Stihl MS 180 household chainsaw makes it possible for its owner to fix most of the tool malfunctions with his own hands. To successfully repair the model, first of all, you need to determine the causes of the breakdown. The repair algorithm in each case is different and depends on the type of malfunction.

Why not start a Stihl 180 chainsaw?

The reason for the lack of launch of the Stihl model, in this case, is to fill the spark plug.

To fix the problem, you need to disassemble the upper part of the tool and unscrew the candle. If a thick layer of soot has formed on the candle, it will need to be cleaned and dried. After that, a clean candle can be screwed back.

What to do if a candle is poured on a Stihl 180 chainsaw?

With frequent use of the tool, one of its fuel tubes may be cut off, which will result in fuel falling onto the candle and other parts of the saw.

If the fuel pipe breaks or a hole appears in it, the tool owner will need to remove the damaged hose and replace it with a new one. In this case, the junction of the new hose with the factory fitting must be carefully treated with sealant.

Oil does not flow to the Stihl 180 chainsaw chain

One of the main causes of the problem in which oil is not supplied is a breakdown of the pump that supplies oil to the saw set. To eliminate the malfunction, you will need to remove the tire and chain, as well as to dismantle the side protective plastic cover. After that, the place under the housing will need to be cleaned and the pump replaced.

If the chain is not lubricated, the cause of the breakage may also be the breakage of one or more oil pipes. In this case, you will need to remove the hoses and replace them.

In this case, the cause must be sought in a contaminated air or built-in fuel filter. Over time, they become worthless, as dirt accumulates on them. To eliminate the malfunction, it will be necessary to clean or completely replace the filter parts.

Another reason for this breakdown lies in the incorrectly configured carburetor. The owner will need to first clean the unit from accumulated dust and oil residues, as well as configure it, according to the manufacturer’s instructions.

In this case, the cause of the sudden breakdown must be sought in the ignition system of the instrument. Often during mechanical shocks, the gap between the flywheel and the factory ignition coil is violated, which leads to 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, loosen the flywheel mount. After that, you will need to insert a template between the flywheel and the ignition coil, and start screwing the bolts back in. As soon as the flywheel comes into contact with the template, the screwing in of the bolts must be stopped.

Stihl MS 180 chainsaw is bad to start on a cold

First you need to make sure that the spark plug is not filled with fuel. If a thick layer of soot has formed on it, then you will need to inspect the fuel system. She could lose her tightness as a result of a broken hose or a broken fuel pump.

If everything is ok with the candles, then you will need to check the air filter. As a result of the intensive operation 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 recoverable, so they will need to be replaced.
