Checking, maintaining and

equipment
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.
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.
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.
Chain brake and front hand guard
Checking brake band wear
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.
Brush off any wood dust, resin and dirt from the chain
brake and clutch drum.Dirt and wear can impair operation
of the brake.
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
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
acceleration and could suffer damage to the engine.
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.
