PEtROL CHAiN SAW FOR tREE SERViCE USER MANUAL
- Sharpen the chain by filing it from the inside to
the outside (fig.20 item 5) all the teeth on one side,
then all the teeth on the opposite side.
- Position the file so that it overhangs by around
1mm (fig.20 item4) over the level where the cut-
ters are located.
CHAiN REPLACEMENt
- If the chain must be replaced, a genuine part
must be used or, in any case, a chain with the
same features (low kickback) and with a safety
link (fig.38).
See the dimensions in the tECHNiCAL DAtA
table.

Chain lubrication:
before each job, please check the efficiency of the
chain lubrication and test the oil level in the tank
(see charter 6 ); do not work without chain lubrica-
tion: even a short use without lubrication, would
definitely damage either the bar or the chain.
The efficiency of the oil flow can be tested (with
accelerated engine) by keeping the tip of the bar
near a surface in order to see some oil drops
(fig.39). Adjust, if needed, the oil flow (paragraph
8.11 and fig.39).
Drive sprocked: check the teeth wear , clearance
on cranck shaft and rubricate the bearing with
bearings grease.

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
maintenance operation) to ensure a consistent
wear and tear.
- Reverse the bar on the occasion of every mainte-
nance operation to ensure more uniform wear.
In case of chain / bar replacement, please use
original spare parts only; the type of bar and chain
originally supplied with the chain saw has been
tested and certificated according to the existing
laws, particularly in order to limit any kick back
danger (see charter A18); therefore using non
original bar and chain can be very dangerous
for the user.
The brand and type of bar and chain are indicated
on the technical data table.

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 environ-
ment require the filter to be cleaned more often.
a) Remove the filter cover (fig. 22) by unscrewing
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).
