When the throttle trigger is released, the engine should
return to an idle speed between 2700-3300 RPM, or
just below the clutch engagement speed. The Attached
Tool must not rotate/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 (counter-clockwise) to decrease
the engine idle speed.
If idle speed adjustment is necessary, and after
adjustment the Attached Tool rotates/moves or the
engine stalls, stop using the Multi-Cutter immediately!
