The Spark Arrester System needs a periodic and accurate
maintenance and cleaning, in particular:
- check periodically the spark arrester screen and substitute it
when holes, bends or deformations appear;
- check carefully if dust, debris or organic material is in contact
with parts of the Spark Arrester System; check especially the
gap between the muffler and the shield; clean it often with
tools or shop air.
For compliance with the standard, two spiked bumpers p.n.
50010050B (A, Fig. 96) have to be mounted, as provided on the
chainsaw in the box.

WARNING: Do not operate your chainsaw if the
muffler is damaged, missing or modified. An
improperly maintained muffler will increase the risk
of fire and hearing loss.

Chain Brake

If the chain brake does not work properly, remove the clutch
cover and clean the chain brake components. Check for wear on
the brake band (A, Fig. 97) and replace if worn or deformed.
WARNING: If the brake band is worn too thin it may break

when the chain brake is triggered. With a broken brake band,
the chain brake will not stop the chain. The chain brake
should be replaced by an authorized service dealer if any part
is worn to less than 0.02" (0.6 mm) thick. Repairs on a chain
brake should be made by an authorized service dealer. Take
your unit to the place of purchase if purchased from a
servicing dealer, or to the nearest authorized service dealer.
Always keep the chain brake mechanism clean and lightly
lubricate the linkage (B, Fig. 98).
Always test the chain brake performance after servicing or
cleaning per the Operation - Chain Brake Section.

WARNING: Check and, if damaged, replace the
chain catcher / safety stop (C, Fig. 97).

Oil Pump (Automatic/Adjustable)

Flow adjustment is pre-set by the manufacturer. Oil flow can be
adjusted by the operator according to specific requirements by
means of the special adjusting screw (D, Fig. 99). Oil flow occurs
only when the chain is moving.
