MAINTENANCE

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 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 0.6 mm (0,024
inch) 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 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.

Apply full throttle and activate the chain brake by tilting your
left wrist forward onto the front hand guard. Do not let go of
the front handle. The chain should stop immediately.

Note! All servicing and repair work on the machine requires
special training. This is especially true of the machine
