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 increas-
ing fuel consumption.
- The air filter should be cleaned more frequently
when the wood being cut is dry or the work envi-
ronment is dusty.
a)
Remove the top cover (fig. 20 part 1) by
loosening 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
outwards.
- If the dirt is hard to remove, 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
long-toothed 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. 33 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).
ENGLISH
9.6 SPARK PLUG
At least once a year or if the engine has
problems starting 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.
