9. MAINTENANCE
DANGER!! Never carry out any test, main-
tenance or repair work with the engine
running.
9.1 CHAIN
See the specific section “8.4 CHAIN”
9.2 BAR
- Periodically clean the chain run groove and the oil
passages.
- Lubricate the sprocket wheel with bearing grease.
- Reverse the bar on the occasion of every mainte-
nance operation to ensure more uniform wear.
9.3 AIR FILTER
A clogged air filter: reduces the efficiency of the engine
and the efficiency of cutting, while increasing fuel con-
sumption.
a) The air filter should be cleaned more frequently when
the wood being cut is dry or the work environment
is dusty.
- Remove the top cover
(fig. 20 part 1) by loos-
ening the screw (fig. 20
part 2).
- Loosen the two retention
knobs (fig. 20 part 3).
- Raise the filter (Fig. 20
part.4).
- Use compressed air to
blow from the inside out-
wards.
- If the dirt is hard to re-
move, wash with hot
soapy water.
b) Change the filter if damaged (deformed and/or
cracked).
9.4 FUEL FILTER
Can be taken out (through the refilling hole Fig. 1 part.16)
with a hook and held with a pair of longtoothed pliers.
Change the filter at least once a year.
- Use an original filter as replacement.
9.5 OIL FILTER
To clean or change the filter, remove the chain cutcher
(fig. 32 part 1) by loosening the two screws (part 2). Take
the rubber cap (part 3) out of the housing and remove
the filter (part 4).
9.6 SPARK PLUG
At least once a year or if the engine has problems start-
ing up properly, check the condition of the spark plug.
Wait for the engine to cool before operation.
1) Take off the cap and loosen the plug using the wrench
provided (fig. 22). If the electrodes are excessively
soiled or are very worn, replace the spark plug with
an equivalent one (fig. 21).
Excessive soiling may be due to:
• The oil ratio used in fuel is too high and/or oil is not of
an appropriate type.
• Air filter is partly clogged.
2) Screw the spark plug manually as far as possible to
avoid damaging its socket. Use the wrench provided
only to tighten it (fig.20).
3) Do not carry out repairs on the machine (if you are
not qualified to do so). Contact an authorized service
centre.
DANGER! In order to maintain the original
safety features, do not make any changes
to the machine. In case of repairs, only use
genuine spare parts.
