OPERATION

ADJUSTING IDLE SPEED

￿If the engine starts, runs, and accelerates but will not idle, turn the idle speed screw “ T ” clockwise to increase idle speed.

￿If the chain turns at idle, turn the idle speed screw “ T ” counterclockwise to reduce the idle RPM and stop the chain movement. If the saw chain still moves at idle speed, contact a Homelite Service Center for adjust- ment and discontinue use until the repair is made.

WARNING:

THE SAW CHAIN SHOULD NEVER TURN AT IDLE. Turn the idle speed screw “T” counterclockwise to reduce the idle RPM and stop the chain, or contact a Homelite Service Center for adjustment and discontinue use until the repair is made.

Serious personal injury may result from the saw chain turning at idle.
