WARNING:
The following features
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 contactof thebar
tip in the danger zone with any hard object.
Kickbackcanalsobecausedby pinchingthe
sawchainalongthetopoftheguidebar. This
action may push the guide bar rapidly back
toward the operator. 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 OFTHE
DEVICES BUILT INTO YOUR SAW. YOU
SHOULD USE THE 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. Your saw has alow kickback chain
and bar as original equipment. Repairs on a
chain brake should be made by an autho-
rized servicing dealer. Take your unit to the
place of purchase if purchased from a ser-
vicing dealer, or to the nearest authorized
master service dealer.
are included on your saw to help reduce the
hazard of kickback; however, such features
will not totally eliminate this danger. As a
chainsaw user,donotrely onlyonsafetyde-
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.

which deflect kickback force and allow

formance requirements when tested on a
representative sample of chain saws be-

in ANSI B175.1.

WARNING:
Computed kickback
angle (CKA) listed on your saw and listed in
the CKA table below represents angle of
kickback your bar and chain combinations
will have when tested in accordance with
CSA (CanadianStandards Association) and
ANSI standards. When purchasing replace-
ment bar and chain, considerations should
be given to the lower CKA values. Lower
CKA values represent safer angles to the
user, higher values indicate more angle and
higher kick energies.Computed angles rep-
resented in the non-activated column indi-
cate total energy and angle associated with-
out activation of the chain brake during
kickback. Activated angle represents chain
stopping time relative to activation angle of
chain brake and resulting kick angle of saw.
In all cases lower CKA values represent a
safer operating environment for the user.

S Position of front and rear handlebars, de-
signedwithdistancebetweenhandlesand
“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 toward the operator if kick-
back occurs.
The following guide bar and chain combina-
tions meet kickback requirements of CSA
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.
