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.

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.

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.

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.

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.

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.

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