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 beendemonstratedtosignificantly re-
duce t henumberandseriousness ofkick-
backs when tested in accordance with
safety requirements for gasoline powered
chain saws as set by ANSI B175.1.

contoured depth gauge and guard link
which deflect kickback force and allow

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

S Front Hand Guard, designed to reduce the
chanceof yourlefthand contactingthechain
if your hand slips off the front handlebar .
S Position of front and rear handlebars, de-
signed with distance between handles and
“in-line”witheach o ther. The spread and“in-
line” position of the hands provided by this
design work togetherto givebalance a ndre-
sistance in controlling the pivot of the saw
back toward the ope rator if kickback o ccurs.
CHAIN BRAKE AND CKA ANGLE
S Chain Brake, designed to stop the chain in
the event o f kick back.
WARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS-
SUME THA T THE CHAIN BRAKE WILL
PROTEC TYOU I NTHE EV ENTOF AKICK-
BACK. Kickback is a l ightning 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 t he
danger zone with any hard object. Kickback
canalsobecausedbypinchingthesawchain
along thetop ofthe guide bar. This actionmay
push the guidebar rapidly back toward th eop-
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 REL Y
UPON ANY OF THE DEVICE S BUILT I NTO
YOUR SA W. YOU SHOULD USE THESAW
PROPERL Y AND CAREFULLY T O A VOID
KICKBACK. Re duced--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 achainbrake should b e m adeby an autho-
rized servicing dealer . Take your unit to the
place of purchase if purchased from a servic-
ing dealer , or to the nearest authorized m aster
service dealer .
S Tipcontactinsomecases maycause alight-
ning fast reverse REACTION, kicking the
guide bar up and back toward the operator .
S Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back toward the operator.
S 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: C omputed kickback
angle(CKA) listedon yoursaw andlisted i nthe
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 t he user , h igher 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
angleofchainbrakeand resulting kick angle o f
saw.In allcaseslower CKAvalues r epresenta
safer operating environment for the user.
The following guide barand chain combina-
tions meet kickback requirements of CSA
Z62.1, Z62.3, &ANSI B175.1when usedon
saws listed in this manual. Use of bar and
chaincombinationsotherthanthoselistedis
not recommended and may not meet the
CKA requirements per standard.
