Idle Speed Adjustment

This Multi-cutter is equipped with non-adjustable fuel mixture carburetor. The idle speed is the only adjust-

ment for the operator.

Please see HONDA ENGINES Owner’s Manual.

The cutting attachment may be rotating during idle speed adjustment. Wear the recommended personal 

protective equipment and observe all safety instructions. Keep hands and body away from the cutting at-

tachment.

When the throttle trigger is released, the engine should return to an idle speed just below the clutch engage-

ment speed.

The cutting attachment must not rotate 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 (counter-clockwise) to decrease the engine idle speed.

If idle speed adjustment is necessary, and after adjustment the cutting attachment rotates or the 

engine stalls, stop using the Multi-cutter immediately!

Contact your local authorized BUSHRANGER Dealer for assistance and servicing.
