STurn idle speed screw counterclockwise to decrease engine speed if trimmer head or any optional attachment moves or spins at idle.

WARNING: Recheck the idle speed after each adjustment. The trimmer head or any optional attachment must not move or spin at idle speed to avoid serious injury to the operator or others.
