Replacing the saw chain

signed for this saw.

(1). Fig.22
CAUTION!: Worn out sprockets may damage the
new chain and must therefore be replaced.
Replacing the clutch drum and sprocket
The replacement of the clutch drum and sprocket
must be performed by a specialist company.
Replacing the fuel filter Fig.23
The felt filter (N) of the fuel filter can become
clogged. It is recommended to replace the fuel filter
once every three months in order to ensure unim-
peded fuel flow to the carburetor.
To remove the fuel filter for replacement, pull it out
through the tank filler neck using a piece of wire bent
at one end to form a hook.
Cleaning the air filter Fig.24/25
Unscrew screw (O) and remove the filter cover (9).
IMPORTANT!: Cover the intake opening with a
clean cloth in order to prevent dirt particles from fall-
ing into the carburetor.
Remove the air filter (P).
CAUTION!: To prevent injury to the eyes, do NOT
blow out dirt particles! Do not use fuel to clean
the air filter.
Clean the air filter with a soft brush.
If the filter is very dirty, clean it in lukewarm water
with dishwashing detergent.
Let the air filter dry completely.
If the filter is very dirty, clean it frequently (several
times a day), because only a clean air filter provides
full engine power.
CAUTION!:
Replace damaged air filters immediately.
Pieces of cloth or large dirt particles can de-
stroy the engine!
Replacing the spark plug Fig.26/27
CAUTION!:
Do not touch the spark plug (Q) or plug cap (R) if
the engine is running (high voltage).
Switch off the engine before starting any main-
tenance work.
A hot engine can cause burns. Wear protective
gloves!
The spark plug (Q) must be replaced in case of dam-
age to the insulator, electrode erosion (burn) or if the
electrodes are very dirty or oily.
Unscrew the screw (O) and take off the air filter cov-
er (9).
Pull the plug cap (R) off the spark plug (Q). Use only
the universal wrench (23) supplied with the saw to
remove the spark plug.
Electrode gap
The electrode gap must be .020" (0.5 mm).
