MAINTENANCE
Fine adjustment of the idle speedT
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.
Brush off any wood dust, resin and dirt from the chain
brake and clutch drum.Dirt and wear can impair operation
of the brake.
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.
!
High speed jet H
Regularly check that the brake band is at least 0.6 mm
thick at its thinnest point.
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.
Checking the front hand guard
CAUTION! If the high speed jet is screwed in too far,
it may damage the piston/cylinder.
Make sure the front hand guard is not damaged and that
there are no visible defects such as cracks.
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.
Move the front hand guard forwards and back to make
sure it moves freely and that it is securely anchored to the
clutch cover.
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.
Checking the inertia brake release
Checking, maintaining and
servicing chain saw safety
equipment
Place the chain saw, with the engine switched off, on a
stump or other stable surface. Release the front handle
and let the saw fall by its own weight, rotating around the
rear handle towards the stump.
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.
