Adjusting Idle Speed
Engine stops while idling
or chain runs while engine is idling
: Check the standard setting.
: Turn the idle speed screw (LA)
slowly clockwise – as far as stop or
until the chain begins to run – then
turn the screw back 1
1
/
2
turn.
If the chain continues moving when
the engine is idling, have your saw
checked and repaired by your
servicing dealer.
Erratic idling behavior, poor
acceleration
(although L screw is open
1
/
4
turn)
Idle setting is too lean:
: Turn low speed screw (L)
counterclockwise – no further than
stop – until the engine runs and
accelerates smoothly .
It is usually necessary to change the
setting of the idle speed screw (LA)
after every correction to the low speed
screw (L).
Fine Tuning for Operation at High
Altitude
A slight correction of the setting may be
necessary if engine power is not
satisfactory when operating at high
altitude:
: Check the standard setting.
: Warm up the engine.
Turn the high speed screw (H) clockwise
(leaner) – no further than stop.
If the setting is too lean there is
a risk of engine damage due to
insufficient lubrication and
overheating.
