CARBURETOR
Before adjusting the carburetor, clean the
starter cover, the air filter (Fig. 27) and warm
up the engine. This engine is designed and
manufactured in order to comply with the
applicable (EU) 2016/1628 Regulations.
The carburetor (Fig.30) is designed to allow
adjustment only of screws L and H, through
-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.
WARNING: With the engine idling, the chain
must never turn. If the chain moves to the
minimum, intervene on the T screw and reduce
the speed of the motor. If the problem persists,
immediately stop the work and contact an
Authorized Service Center to solve the problem.
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.
