ADJUSTMENT

WARNING: Keep others away when making idle speed adjustments. The trimmer head, blade or any optional attachment will be spinning during most of this procedure. Wear your protective equipment and observe all safe- ty precautions. After making adjustments, the trimmer head, blade or any optional attachment must not move/spin at idle speed.

engine speed if engine stalls or dies.
