KICKBACK SAF ETY FEATURES
WARNING: The following features
are included on your saw to help reduce the
hazard of kickback; however, such features
will not totally eliminate this dangerous reac-
tion. As a chain saw user, do notrely only on
safety devices. You must follow all safety
precautions, instructions, and maintenance
in this manual to help avoid kickback and
other forces which can result in serious
injury.
S Reduced--Kickback Guide Bar , designed
with a small radius tip which reduces the
size of the k ickback danger zone on the
bar tip. A Reduced--Kickback Guide Bar
has been demonstrated to significantly re-
duce the number and seriousness of kick-
backs when tested in accordance with
safety requirements for gasoline powered
chain saws as set by ANSI B175.1.

S Position of fr ont and rear handlebars, de-
signed with distancebetween handlesand
“in-line” with each other. The spread and
“in-line” position of the hands provided by
this design work together to give balance
and resistance in controlling the pivot of
the saw back t oward the operator if kick-
back occurs.
CHAIN BRAKE AND CK A ANGLE
S Chain Brake, designed to stop the chain in
the event of kickback.
WARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS-
SUME THAT THE CHAIN BRAKE WILL
PROTECT YOU IN THE EVENT OF A
KICKBACK. Kickback is a lightning fast ac-
tion which throws the bar and rotating chain
back and up toward the operator . Kickback
can be caused by allowing contact of the bar
tip in the danger zone with any hard object.
Kickback canalsobe caused by pinchingthe
saw chainalong thetopof theguide bar. This
action may pus h the guide bar rapidly bac k
toward the operator. Either of these events
may cause you to lose control of the saw
which could result in serious injur y or even
death. DO NOT REL Y UPON ANY OF THE
DEVICES BUILT INTO YOUR SAW. YOU
SHOULD USETHE SAW PROPERLY AND
CAREFULLY TO AVOID KICKBACK. Re-
duced--kickback guide bars and low--kick-
back saw chains reduce the chance and
magnitude of kickback and are recom-
mended. Yoursaw has a lowkickback chain
and bar as original equipment. Repairs on a
chain brake should be made by an autho-
