6.4 Replacing the saw chain (Fig. 55)
Only use saw chains and guide bars designed for this
chain saw!
Check the pinion before mounting a new chain.
Worn pinions may damage the new saw chain and must
thus be replaced.
6.5 Replacing the suction head (Fig. 56)
The felt filter (N) of the suction head may get obstructed. It is
recommended to replace the suction head once quarterly to
ensure trouble-free fuel circulation to the carburetor.
To remove and replace the suction head, extract it through
the tank inlet using a piece of wire having a hook-shaped
bent end.

Unscrew the screw (23) and extract the cover of the filter
box (20).
IMPORTANT: Cover the admission port with a clean cloth
to avoid particles of debris falling into the carburetor. Extract
the air filter (24).
To avoid injuring your eyes, do NOT blow the particles
of debris! 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 with lukewarm water with
dish detergent.
Let the air filter dry completely.
If the filter is very dirty, clean it frequently (several times a
day) because the whole of the engine power can be
extracted only with a clean air filter.
Replace damaged air filters immediately.
The cloth pieces or particles of debris may damage the
engine.

isolator us damaged, the electrode is eroded (is burned) o if
the electrodes are very dirty or oily.
