High speed jet H
Checking the front hand guard
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.
Make sure the front hand guard is not damaged and that there
are no visible defects such as cracks.
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.
Move the front hand guard forwards and back to make sure it
moves freely and that it is securely anchored to the clutch
cover.
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 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.
