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 0.024 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.
Note! All servicing and repair work on the machine requires 
special training. This is especially true of the machine
safety equipment. If your machine fails any of the checks 
described below we recommend you to contact our 
servicing dealer.
