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

safety requirements for gasoline powered
chain saws as set by ANSI B175.1.

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 bartip in t he
danger zone with any hard object. Kickback
canalsobecausedbypinchingthesawchain
along thetop ofthe guidebar. This actionmay
push theguide ba r r apidly back toward th eop-
erator. Either of these events may cause you
to lose control of the saw which could result i n
serious injury or even death. DO NOT REL Y
UPON ANY OF THE DEV ICE S BUILT I N TO

KICKBACK. Re duced--kickback guide bars
and low--kickback saw chains reduce the
chance and magnitude of kickback an d are
recommended. Your saw has a low kickback
chain and bar as original equipment. Repairs
on achain b rake shouldbe madeby anautho-
rized servicing dealer. Take your unit to the

your bar and chain combinations will have
when tested in accordance with CSA (Cana-

chain, considerations should be given to the
lower CKA values. Lower CKA values repre-
sent safer angles to t he user,higher values in-
dicate more angle and higher kick energies.

The following guidebar and chaincombina-
tions meet kickback requirements of CSA
Standards Z62.1, Z62.3, & ANSI B175.1
when used on saws listed in this manual.
Use of bar and chain combinations other
than those listed is not recommended and
may not meet the CKA requirements per
