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 (Fig. 32). Oil flow occurs only
when the chain is moving.
WARNING - Never use scavenge oil.
STARTING UNIT - Use a brush or compressed
air to keep the cooling louvers of the starter
assembly free and clean.
ENGINE - Clean the c ylinder fins with
compressed air or a brush periodically.
Dangerous overheating of engine may occur
due to impurities on the cylinder.
SPARK PLUG - Clean the spark plug and check
the electrode gap periodically (Fig. 29).
Use TORCH L8RTF or of other brand with the
same thermal grade.
CHAIN BRAKE - If the chain brake does not work
properly, remove the chain cover and the clean
brake components. Replace the chain brake band
if worn or deformed.
GUIDE BAR - Turn the guide bar and check that
the lubrication holes are free from impurities.
Never use fuel for cleaning operations.
CARBURETOR
Before adjusting the carburetor, clean the starter
cover, the air filter (Fig. 27) and warm up the
engine.
Idle screw T (Fig. 30) is adjusted in order to ensure
a good safety margin between idle running and
clutch engagement.
This engine is designed and manufactured in
order to comply with the applicable 97/68/EC,
2002/88/EC and 2012/46/EC Directive.
WARNING - Weather conditions and
altitude may affect carburation. Do not
allow anyone to stay close to the chainsaw
while working or while adjusting the
carburetor.
MUFFLER
WARNING – This muffler incorporates
a catalytic converter, needed in order
to ensure the engine complies with current
emissions standards. Never attempt to modify or
remove the catalytic converter: in doing so, you
will be breaking the law.
WARNING – Mufflers with catalytic
converters become very hot during
operation, and retain heat for a long time
after the engine has been stopped. This is the
case even with the engine idling. Contact can
burn the skin. Always remember the potential
fire risk!
CAUTION – If the muffler is damaged, it
must be replaced. If the muffler frequently
becomes blocked, this could be an indication
that the efficiency of the catalytic converter is
limited.
WARNING – Do not use the chain saw if
the muffler is damaged or missing, or
has been altered in any way. Operating the
machine with an improperly maintained
muffler will increase the risk of fire and
hearing loss.
EXTRA MAINTANANCE ADVISABLE
It is advisable to inspect the machine by a
specialized technician at an authorized service
network at the end of season, if used intensively,
and every two years if with normal use.
WARNING! – Any maintenance operations
not specifically dealt with in this manual
must be carried out by an authorized service
center. To ensure that your chainsaw continues
to function correctly, use only ORIGINAL
REPLACEMENT PARTS.
Any unauthorized changes and/or
use of non-original replacement parts
may result in serious injury or death to the
operator or third parties.
TRANSPORTION
Carry the chainsaw with the engine stopped,
guide bar to the rear and chain cover on (Fig. 31).
