Numbers preceding the descriptions correspond with the num-
bers 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 spe-
cially designed depth gauges and guard links.

intensity of kickback.
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 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
operator’s left hand in the event it slips off the front han-
dle while saw is running.
4

®
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

tripped. Stop switch must be pushed to ON position to
start or restart engine.
8
