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.
23 CHAIN CATCHER reduces the danger of injury in the event
saw chain breaks or derails during operation. The chain
catcher is designed to intercept a whipping chain.
