1-2. SAFETY FEATURES

Numbers preceding the descriptions correspond with the num- bers on preceding page to help you locate the safety feature.

1LOW KICKBACK SAW CHAIN helps significantly reduce kickback, or the intensity of kickback, due to specially designed depth gauges and guard links.

2GUIDE BAR reduced kickback guide bar helps significantly reduce kickback by reducing the guide bar tip radius.

3SPARK ARRESTER SCREEN retains carbon and other flammable particles over 0.023 inches (0.6mm) in size from engine exhaust flow. Compliance with local, state and feder- al laws and/or regulations governing the use of a spark arrester screen is the user’s responsibility. See Safety Precautions for additional information.

4CHAIN BRAKE® LEVER / HAND GUARD protects the

operator’s left hand in the event it slips off the front handle while saw is running.

4CHAIN BRAKE® is a safety feature designed to reduce the possibility of injury due to kickback by stopping a moving saw chain in milliseconds. It is activated by the CHAIN

BRAKE® lever.

7STOP SWITCH immediately stops the engine when tripped. Stop switch must be pushed to ON position to start or restart engine.

8SAFETY TRIGGER prevents accidental acceleration of the engine. Throttle trigger (21) cannot be squeezed unless the safety latch is depressed.
