BACK.
Kickback is a lightning fast action
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
can also be caused by pinching the saw chain
along the top of the guide bar. This actionmay
push the guide bar rapidly back toward theop-
erator. Either of these events may cause you
to lose control of the saw which could result in
serious injury or even death. DO NOT RELY
UPON ANY OF THE DEVICES BUILT INTO
YOUR SAW. YOU SHOULD USE THE SAW
PROPERLY AND CAREFULLY TO AVOID
vices.
You must follow all safety precau-
tions, 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 kickback 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.
KICKBACK.
Reduced--kickback guide bars
and low--kickback saw chains reduce the
chance and magnitude of kickback and are
recommended. Your saw has a low kickback
chain and bar as original equipment. Repairs
on a chainbrake shouldbe madeby anautho-
rized servicing dealer. Take your unit to the
place of purchase if purchased from a servic-
ing dealer, or to the nearest authorized master
service dealer.

Either of these reactions may cause you to
lose control of the saw which could result in
serious injury.Do not rely exclusively upon
the safety devices built into your saw.
WARNING:
Computed kickback
angle(CKA) listedonyoursaw andlistedinthe
CKA table below represents angle of kickback
your bar and chain combinations will have
when tested in accordance with CSA (Cana-
dian Standards Association) and ANSI stan-
dards. When purchasing replacement bar and
chain, considerations should be given to the
lower CKA values. Lower CKA values repre-
sent safer angles to the user, higher values in-
dicate more angle and higher kick energies.
Computed angles represented in the non-acti-
vated column indicate total energy and angle
associated without activation of the chain
brake during kickback. Activated angle repre-
sents chain stopping time relative to activation

Z62.1, Z62.3, & ANSI B175.1 when used on
saws listed in this manual. Use of bar and
chaincombinations other thanthose listedis
not recommended and may not meet the
CKA requirements per standard.
