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
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.

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 servi-
cing chain saw safety equipment
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.

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.
MAINTENANCE
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.
