8. MAINTENANCE AND STORAGE
Correct maintenance is essential to maintain the
original efficiency and safety of the machine over
time.
WARNING!
!
During maintenance oper-
ations:
– Remove the spark plug cap.
– Wait until the engine is sufficiently cold.
– Use protective gloves when handling the
bar and chain.
– Keep the bar protection devices on, except
when intervening directly on the bar or the
chain.
– Never dispose of oils, fuel or other polluting
materials in unauthorised places.
CYLINDER AND SILENCER
To reduce fire risks, periodically clean the cylin-
der flaps with compressed air and clear the
silencer area to get rid of sawdust, branches,
leaves or other debris.
STARTING SYSTEM
To avoid overheating and damage to the engine,
always keep the cooling air vents clean and free
of sawdust and debris.
The starter rope must be replaced as soon as it
shows signs of wear.
CLUTCH UNIT
Keep the clutch bell free of sawdust and debris.
Have your dealer check the greasing of the inter-
nal bearing every 30 hours (approx.).
CHAIN BRAKE
Regularly check the efficiency of the chain brake
and the condition of the metal band around the
clutch bell.
MAINTENANCE AND STORAGE
Replace this band when the points in contact
with the clutch bell wear down to about half the
thickness of the two ends not subject to rubbing.
CHAIN SPROCKET (Fig. 22)
Regularly check the condition of the sprocket
and replace it when wear exceeds 0.5 mm.
Do not mount a new chain with a worn sprocket
or vice-versa.
CHAIN CATCHER
This is an important safety device that restrains
the chain if it breaks or degrooves.
Regularly check the condition of the chain
catcher and replace it if it gets damaged.
NUTS AND SCREWS
Periodically check that all the nuts and screws
are securely tightened and the handgrips are
tightly fastened.
CLEANING THE AIR FILTER (Fig. 23)
IMPORTANT
Cleaning the air filter is es-
sential to guarantee the efficiency and duration
of the machine. Do not work with a damaged fil-
ter or without a filter, as this could permanently
damage the engine.
It must be cleaned after every 8-10 working
hours.
Clean the filter as follows:
– Remove the cover (1) and filter element (2).
– Gently tap the filter element (2) to remove the
dirt and, if necessary, clean it with low pres-
sure compressed air.
IMPORTANT
The filter element (2) must
