Adjusting the carburetor
CAUTION: Carburetor adjustment may only be done by a 
specialist MAKITA service center! 
Only adjusting screw (S) can be manipulated by the user. 
If the saw chain moves in idle (i.e. without the throttle being 
pressed), it is imperative to correct the idle speed! 
Do not adjust the idle speed until after complete assembly 
and testing of the saw!
Idle speed  adjustment must only  be undertaken when 
the engine is warm, with a clean air lter and properly in-
stalled guide bar and chain. 
Use a screwdriver (5/32” (4 mm) blade) for idle speed adjust-
ments. 
Adjusting the idle speed
Turn adjusting screw (S) counter-clockwise (unscrew): Idle 
speed decreases. 
Turn adjusting screw (S)  clockwise  (screw in):  Idle  speed 
increases. 
Important: If the saw chain still moves during idle  even 
after you have adjusted the idle speed, do  NOT use the 
saw. Take it to a MAKITA service center!
