8. MAINTENANCE AND STORAGE

WARNING!
For your safety and that of
others:
– Correct maintenance is essential to main-
tain the original efficiency and safety of the
machine over time.
– Keep all nuts, bolts and screws tight to be
sure the equipment is in safe working con-
dition.
– Never use the machine with worn or dam-
aged parts. Damaged parts are to be re-
placed and never repaired.
– Only use original spare parts. Parts that are
not of the same quality can seriously dam-
age the equipment and compromise safety.
WARNING!
During maintenance op-
erations:
– 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 (Fig. 19)
To reduce fire risks, periodically clean the cylinder
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 (Fig. 20)
Keep the clutch bell free of sawdust and debris,
remove the casing (as illustrated in Chap. 4.1) and
replace it correctly when the operation has been
completed. Have your dealer check the greasing
of the internal 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, remove the casing (as illustrated in
Chap. 4.1) and replace it correctly when the opera-
tion has been completed.
Replace this band when the points in contact with
the clutch bell wear down to about half the thick-
ness of the two ends not subject to rubbing.
CHAIN SPROCKET
Regularly check the condition of the sprocket with
your local retailer and replace it when wear ex-
ceeds the accepted limits.
Do not mount a new chain with a worn sprocket
or vice-versa.
LUBRICATION HOLE (Fig. 21)
Periodically remove the casing (as illustrated in
Chap. 4.1) remove the bar and check that neither
the machine lubrication holes (1) or the bar (2)
are clogged.
CHAIN CATCHER
This is an important safety device that restrains the
chain if it breaks or degrooves.
Regularly check the condition of the pin and re-
place it if 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. 22)
sen tial to guarantee the efficiency and duration of
the machine. Do not work with a damaged filter or
without a filter, as this could permanently damage
the engine.
It must be cleaned after every 15 working hours.
