carburetor’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.
To adjust the carburetor correctly you should contact a
mechanic with access to a rev counter.
CAUTION! As the spark is cut off, the rev counter does not
show speeds higher than 13600 rpm.
Correctly adjusted carburetor
When the carburetor is correctly adjusted the machine
accelerates without hesitation and the machine 4-cycles a
little at max. speed. 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, maintaining and
servicing chain saw safety
equipment
Chain brake and front hand guard
Checking brake band wear
Brush off any wood dust, resin and dirt from the chain
brake and clutch drum. Dirt and wear can impair operation
of the brake.
Regularly check that the brake band is at least 0.024 inch
(0.6 mm) thick at its thinnest point.
Checking the front hand guard
Make sure the front hand guard is not damaged and that
there are no visible defects such as cracks.
Move the front hand guard forwards and back to make
sure it moves freely and that it is securely anchored to the
clutch cover.
Checking the inertia brake release
With the engine turned off, hold the chain saw over a
stump or other firm object. Let go of the front handle so
that the bar drops towards the stump as the chain saw
rotates around the rear handle.
When the bar hits the stump the brake should be
applied.
Checking the brake trigger
Place the chain saw on firm ground and start it. Make sure
the chain does not touch the ground or any other object.
See the instructions under the heading Start and stop.
Grasp the chain saw firmly, wrapping your fingers and
thumbs around the handles.
Note! All servicing and repair work on the machine
requires special training. This is especially true of the
machine′s safety equipment. If your machine fails any of
the checks described below we recommend you to
contact our servicing dealer.
