replace if necessary.
: Check the spark arresting screen* in
the muffler and clean or replace if
necessary.

* see "Guide to Using this Manual"
Adjusting Idle Speed
Engine stops while idling
: Open the low speed screw (L) 1/4
turn.
: Turn the idle speed screw (LA)
slowly clockwise until the chain
begins to run – then turn the screw
back 1/2 turn.
Chain runs while engine is idling
: Open the low speed screw (L)
1/4 turn.
: Turn the idle speed screw (LA)
slowly counterclockwise until the
chain stops running – then turn the
screw another 1/2 turn in the same
direction.
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).
