speed. Wear all protective clothing and keep all bys-
tanders, children, and pets at least 50 ft. away. Make

• If the engine stops, increase the idle speed. Use a
small screwdriver to turn the idle speed screw clock-
wise, 1/8 of a turn at a time, until the engine idles
smoothly (Fig. 17).
• If the cutting blades spin when the engine idles, redu-
ce the idle speed. Turn the idle speed screw counterc-
lockwise, 1/8 of a turn at a time, until the cutting head
stops moving.
WARNING:
The cutting attachment should never turn at idle. Turn
the idle speed screw counterclockwise to reduce the
idle RPM and stop the cutting attachment, or contact us
at 1-800-261-3981 for adjustment and discontinue use
until the repair is made. Serious injury could result from
the cutting attachment turning at idle.
