WARNING! For your safety and that of
others:
– Correct maintenance is essential to main-
tain the original eciency 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 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-
te rials in unauthorised places.
1. ENGINE COOLING
To avoid overheating and damage to the engine,
always keep the cooling air vents clean and free
of sawdust and debris.
2. CHAIN BRAKE
Regularly check the eciency 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.
Regularly check the condition of the chain catcher
and replace it if it gets damaged.
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
WARNING! To ensure that the chain-
saw works safely and eciently, it is essential
that the cutting components are well-sharp-
ened. Any work on the chain and bar requires
specic skills and special tools in order to do
the work properly. For safety purposes, we
recommend you contact your Dealer.
Sharpening is necessary when:
• The sawdust looks like dust.
• Cutting becomes more dicult.
• 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.
Replace the chain whenever:
– The length of the cutting edges reduces to 5
mm or less;
– There is too much play between the links and
the rivets.
7. EMPTYING AND FLUSHING
THE OIL TANK
(Only if organic oil is used for the chain)
The use of some types of organic oil may cause
deposits or fouling after a certain period of use.
If this happens, before leaving the machine unu-
sed for a long period of time:
– disassemble the chain and the bar;
– empty the oil tank;
– pour a specic liquid cleanser in the tank, to
about half the maximum level;
