MAINTENANCE
Low speed jet L
Checking, maintaining and
servicing chain saw safety
equipment
Turn the low speed jet L clockwise until it stops. If the
engine accelerates poorly or idles unevenly, turn the low
speed jet L anticlockwise until good acceleration and
idling are achieved.
Note! All service and repair work on the machine
demands special training. This is especially true of the
machine’s safety equipment.If your machine fails any of
the checks described below we recommend that you
take it to your service workshop.
Fine adjustment of the idle speed T
Adjust the idle speed with the T-screw. If it is necessary to
re-adjust, turn the T-screw clockwise while the engine is
running, until the chain starts to rotate. Then turn anti-
clockwise until the chain stops. When the idle speed is
correctly adjusted the engine should run smoothly in
every position and the engine speed should be safely
below the speed at which the chain starts to rotate.
Chain brake and front hand guard
Checking brake band wear
WARNING! Contact your servicing
dealer, if the idle speed setting cannot be
adjusted so that the chain stops. Do not
use the chain saw until it has been
properly adjusted or repaired.
!
Brush off any wood dust, resin and dirt from the chain
brake and clutch drum. Dirt and wear can impair
operation of the brake.
High speed jet H
At the factory the engine is adjusted at sea level.
When working at a high altitude or in different
weather conditions, temperatures and atmospheric
humidity, it may be necessary to make minor
adjustments to the high speed jet.
CAUTION! If the high speed jet is screwed in too far,
it may damage the piston/cylinder.
When test run at the factory, the high speed jet is set so
that the engine satisfies the applicable legal requirements
at the same time as achieving maximum performance.
The carburettor’s high speed jet is then locked using a
limiter cap in the fully screwed out position.The limiter cap
limits the potential to adjust the high speed jet to at most
half a turn.
Regularly check that the brake band is at least 0.6 mm
thick at its thinnest point.
Checking the front hand guard
CAUTION! There is an integrated speed governor in the
ignition system that limits the maximum speed to 13600
rpm. The maximum speed will not exceed 13600 rpm
when the high speed jet is adjusted (screwed in). When
the speed governor is activated, you will get the same
sound experience as when the chain saw 4-cycles.
Make sure the front hand guard is not damaged and that
there are no visible defects such as cracks.
To adjust the carburettor correctly you should contact a
mechanic with access to a rev counter.
Move the front hand guard forwards and back to make
sure it moves freely and that it is securely anchored to the
clutch cover.
CAUTION! As the spark is cut off, the rev counter does not
show speeds higher than 13600 rpm.
Correctly adjusted carburettor
When the carburettor is correctly adjusted the machine
accelerates without hesitation and 4-cycles a little at full
throttle. It is also important that the chain does not rotate
at idle. If the L-jet is set too lean it may cause starting
difficulties and poor acceleration. If the H-jet is set too
lean the machine will have less power, poor acceleration
and could suffer damage to the engine.
