WARNING: Do not use a product that has a

arrestor mesh on the muffler is missing or
defective.

the product. (Fig. 93)
3. If your product has a spark arrestor mesh, clean the
spark arrestor mesh weekly. Replace a damaged
spark arrestor mesh. (Fig. 94)
CAUTION: If the spark arrestor mesh is
blocked, the product becomes too hot and
this causes damage to the cylinder and
piston.
To adjust the idle speed screw (T)
The basic carburetor adjustments are done at the
factory. You can adjust the idle speed but for more
adjustments, refer to your servicing dealer.
To give the components of the engine sufficient
lubrication during run-in, adjust the idle speed. Adjust
the idle speed to the recommended idle speed. Refer to
Technical data on page 26 .

CAUTION: If the saw chain rotates at idle
speed, turn the idle speed screw
counterclockwise until the saw chain stops.
1. Start the product.
2. Turn the idle speed screw clockwise until the saw
chain starts to rotate.
3. Turn the idle speed screw counterclockwise until the
saw chain stops.
Note: The idle speed is correctly adjusted when the
engine runs correctly in all positions. The idle speed
must also be safely below the speed at which the saw
chain starts to rotate.
WARNING: If the saw chain does not stop
when you turn the idle speed screw, speak
to your servicing dealer. Do not use the
product until it is correctly adjusted.
To examine if the carburetor is correctly
adjusted
• Make sure that the product has the correct
acceleration capacity.
• Make sure that the saw chain does not rotate at idle
speed.
CAUTION: Incorrect adjustments can
cause damage to the engine.
To clean the air filter
Clean the air filter regularly from dirt and dust. This
prevents carburetor malfunctions, starting problems,
loss of engine power, wear to engine parts and more
fuel consumption than usual.
1. Remove the cylinder cover and the air filter.
2. Use a brush or shake the air filter clean. Use
detergent and water to clean it fully.
Note: An air filter that is used for a long time can not
be fully cleaned. Replace the air filter regularly and
always replace a defective air filter.
3. Attach the air filter and make sure that the air filter
seals tightly against the filter holder. (Fig. 95)
Note: Because of different work conditions, weather or
season, your product can be used with different types of
air filter. Speak to your servicing dealer for more
information.
