Idle Speed Adjustment
This Hedge Trimmer is equipped with non-adjustable fuel mixture carburetor. The idle speed is the only
adjustment for the operator.
The blades may be moving during idle speed adjustment. Wear the
recommended personal protective equipment and observe all safety
instructions. Keep hands and body away from the blades.
When the throttle trigger is released, the engine should return to an idle speed.
The correct speed is 2700 - 3300 min
-1
(or just below the clutch engagement
speed ). The attached tool must not move and the engine should not stall
(stop running) at engine idle speed.
To adjust the engine idle speed, rotate the idle speed adjustment screw on the carburetor.
・
Turn the idle speed screw in (clockwise) to increase the engine idle speed.
・
Turn the screw out (counterclockwise) to decrease the engine idle speed.
If idle speed adjustment is necessary, and after adjustment the blades moves or the engine stalls,
stop using the Hedge Trimmer immediately!
Contact your local authorized MARUYAMA Dealer for assistance and servicing.
