Idle Speed Adjustment

Allow engine to idle. Adjust speed until engine runs without trimmer head moving or spinning (idle too fast) or stalling (idle speed too slow). S Turn idle speed screw clockwise to increase engine speed if engine stalls or

dies.

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

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