8. MAINTENANCE AND STORAGE

WARNING!
For your safety and that
of others:
– Correct maintenance is essential to maintain
the original efficiency and safety of the ma-
chine 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 oper-
ations:
– Unplug the machine from the mains.
– 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 or other polluting ma-
terials in unauthorised places.
1. ENGINE COOLING
To avoid overheating and damage to the engine, al-
ways keep the cooling air vents clean and free of
sawdust and debris.
2. CHAIN BRAKE
Regularly check the efficiency of the chain brake.
3. CHAIN SPROCKET (Fig. 20)
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.
4. CHAIN CATCHER
This is an important safety device that restrains
the chain if it breaks or degrooves.

5. NUTS AND SCREWS
Periodically check that all the nuts and screws are
securely tightened and the handgrips are tightly
fastened.
6. SHARPENING THE CHAIN
saw works safely and efficiently, it is essential
that the cutting components are well-sharp-
ened. Any work on the chain and bar require
specific experience and special tools. For
safety purposes, we recommend you contact
your dealer to ensure work is done correctly.
Sharpening is necessary when:
• The sawdust looks like dust.
• Cutting becomes more difficult.
• The cut is not straight.
• Vibrations increase.
A specialized centre will sharpen the chain using
the right tools to ensure minimum removal of ma-
terial and even sharpness on all the cutting edges.
If you sharpen the chain yourself, use special
round-section files with the right diameter depen-
ding on the type of chain (see "Chain Maintenance
Table"). You need a certain amount of skill and
experience to avoid damaging the cutting edges.
Sharpen the chain as follows (Fig. 21):
– Disconnect the machine from the mains, relea-
– Tighten the chain if it is loose.
– Mount the file in the guide and then insert it in the
