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).
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.
