IDLE SPEED ADjUSTMENT

If the blades move at idle, the idle speed screw needs adjust-
ing on the engine. Turn the idle speed screw counterclockwise
to reduce the idle RPM and stop the blade movement. If the
blades still move at idle speed, contact a service dealer for
adjustment and discontinue use until the repair is made.
WARNING:
The blades should never move at idle. Turn the idle speed
screw counterclockwise to reduce the idle RPM and stop
the blades, or contact a service dealer for adjustment and
discontinue use until the repair is made. Serious personal
injury may result from the blades turning at idle.
