CARBURETOR ADJUSTMENT
This Hedge Trimmer is equipped with non-adjustable fuel mixture carburetor. The engine idle
speed is the only adjustment to the Operator.
The cutting blades may be moving during idle speed adjustment. Wear the recommended person-
al protective equipment and observe all safety instructions. Keep hands and body away from blade
area.
Engine Idle Speed:
When the throttle trigger is released the engine should return to an idle speed which is 2700 ~3300
rpm or just below clutch engagement speed. The cutting blades must not move and the engine
should not stall (stop running) at engine idle speed.
The engine idle speed is adjusted by rotating the
idle speed screw on the carburetor. Turning the
idle speed screw in (clockwise) increases engine
speed while turning the screw out decreases
engine speed.
If idle speed adjustment is necessary and after adjustment the cutting blades move or the engine
stalls, stop using the Hedge Trimmer immediately!
Contact your local authorized Maruyama Dealer for assistance and servicing.

of the Hedge Trimmer.
The MARUYAMA Hedge Trimmers is designed for cutting and trimming foliage and small branches
