Cleaning the guide bar, lubricating the sprocket
nose Fig. 21
CAUTION!: Protective gloves must be worn!
Regularly inspect the bearing surfaces of the guide
bar for damage, and clean them with a suitable tool.
If the saw is used intensively it will be necessary to
lubricate the return sprocket bearings (G) regularly
(once a week). To do this, first thoroughly clean the 2
mm hole at the tip of the guide bar (H), and then press
in a small amount of multi-purpose grease.
Multi-purpose grease and grease guns are available
in specialty retail trade.
Replacing the saw chain
CAUTION!: Use only chains and guide bars designed
for this saw.
Check the sprocket (E) before mounting a new chain
(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 unimpeded 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 falling 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.

nance work.
A hot engine can cause burns. Wear protective
gloves!

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 cover (9).
Pull the plug cap (R) off the spark plug (Q). Use only
the universal wrench (23) supplied with the saw to re-
move the spark plug.
