Numbers preceding the descriptions correspond with the
numbers on preceding page to help you locate the safety
feature.

LOW KICKBACK SAW CHAIN helps significantly
reduce kickback, or the intensity of kickback, due to
specially designed depth gauges and guard links.
3 SPARK 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 federal laws and/or regulations gov-
erning 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 operator’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 acti-
vated 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 (20) 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.
