CARBURETOR
EST
Before adjusting the carburetor, clean the
starter cover, the air filter (Fig. 27) and warm
LT
up the engine. This engine is designed and
manufactured in order to comply with the
applicable 97/68/EC, 2002/88/EC and 2012/46/
RO
EC Directive.
The carburetor (Fig.30) is designed to allow
adjustment only of screws L and H, through
34
-¼ turn. The range of adjustment allowed
by turning screws L and H through -¼ turn is
factory-set and cannot be chenged by the user.
WARNING – Don't try to force the screws
outside the range!
Idle screw T is adjusted in order to ensure a good
safety margin between idle running and clutch
engagement.
Screw L must be adjusted so that the engine
promptly responds to sharp accelerations and
gives good idle operation.
Screw H must be adjusted so that the engine
gives maximum power during the cutting phase.
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.
