ADJUSTING THE IDLE SPEED

safety instructions to prevent serious personal injury.
If the engine will not idle properly:

If the engine still will not idle properly, adjust the idle speed:
1. Start the engine. Refer to Starting and Stopping.
2. Release the throttle control and let the engine idle.
• If the engine stops, increase the idle speed. Use a small

1/8 of a turn at a time, until the engine idles smoothly (Fig. 18).
If the cutting head spins when the engine idles, reduce the idle
speed. Turn the idle speed screw counterclockwise, 1/8 of a
turn at a time, until the cutting head stops moving (Fig. 18).
If the engine still will not idle properly, and any of the following
conditions are true, take the unit to a Sears or other qualified service
dealer:
the engine hesitates or stalls on acceleration
there is a loss of engine power
