PETROL CHAIN SAW FOR TREE SERVICE USER MANUAL

9. SCHEDULED MAINTENANCE

DANGER!! Do not carry out any
checking, maintenance and repair
operations with the engine running.
9.1 CHAIN
See paragraph "8.10 CHAIN"

9.2 GUIDE BAR

- Periodically clean the chain sliding groove and
the oil ports.
- Lubricate the pinion with bearing grease.
- Turn the guide bar upside down (with any main-
tenance operation) to ensure a consistent wear
and tear.

9.3 AIR FILTER

A blocked air filter reduces the engine perform-
ance, the cutting efficiency, and increases fuel
consumption.
- Cutting dry wood and working in a dusty envi-
ronment require the filter to be cleaned more
often.
a) Remove the filter cover (fig. 22) by unscrew-
ing the knob.
- Lift the filter (fig.23).
- Separate the two halves (fig.24) by using a
screwdriver (if required).
- Blow with compressed air from the inside to
the outside.
b) Replace the filter if damaged (warped and/or
split).

9.4 FUEL FILTER

Can be removed (through the refuelling hole
fig.1 item 13) by using a hook and by holding it
with long nose pliers.
Replace the filter at least once a year.

9.5 OIL FILTER

Can be removed for cleaning (through the refu-
elling hole (fig.1 item14) by using a hook and
by holding it with long nose pliers.
Replace it if it appears damaged.
- Position the filter in the bottom right section of
the tank (to ensure the oil is correctly drawn).

9.6 SPARK PLUG

Check the condition of the spark plug at least
once a year or if the engine struggles to start.
Wait until the engine cools down before carrying
out the operation.
1) Remove the cap and unscrew the spark plug
with the key supplied (fig.25).
If stubborn dirt and high wear of the electrodes
is noticed, replace with a spark plug of the same
type (fig.26).
Stubborn dirt can occur if:
# the oil in the fuel is too much and/or the oil
quality is unsuitable.
# the air filter is partly obstructed.
2) Manually screw the spark plug to the end of
its thread to avoid damaging its housing. Use a
suitable key only for the tightening operation
(fig.25).
3) Do not carry out repair work on the chain saw
(unless you are qualified to do so). Contact an
approved service centre.
DANGER!! In order to maintain the
original safety conditions, do not
carry out any alterations on the chain saw.
When carrying out repair work, only use
genuine parts.
