1-2. SAFETY FEATURES
Numbers preceding the descriptions correspond with the num-
bers on preceding page to help you locate the safety feature.
1 LOW KICKBACK SAW CHAIN helps significantly reduce
kickback, or the intensity of kickback, due to specially
designed depth gauges and guard links.
2 GUIDE BAR reduced kickback guide bar helps significantly
reduce kickback by reducing the guide bar tip radius.
3 SPARK ARRESTER SCREEN retains carbon and other
flammable particles over 0.023 inches (0.6mm) in size from
engine e
xhaust 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.
4 CHAIN BRAKE
®
LEVER / HAND GUARD protects the
oper
ator’s left hand in the event it slips off the front handle
while saw is running.
4 CHAIN 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.
7 STOP SWITCH immediately stops the engine when tripped.
Stop switch must be pushed to ON position to start or restart
engine.
8 SAFETY TRIGGER prevents accidental acceleration of the
engine. Throttle trigger (21) cannot be squeezed unless the
safety latch is depressed.
