KICKBACK SAFETY FEAT URE S
WARNING: The following features
are inc luded on your saw to help r educe the
hazard of kickback; however, such features
will not totally eliminate this danger. As a
chain saw user ,do notrely onlyon safety de-
vices. Yo u 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 ofkick-
backs when tested in accordance with
safety requirements for gasoline powered
chain saws as set b y A NSI B 175.1.

S Low--Kickback Chain, designed with a
contoured depth gauge and guard link
which deflect kickback force and allow
wood togradually ride intothe cutter.Low--

formance requirements when t ested on a
representative sample of chain saws be-
low 3.8 cubic inch displacement specified
in A NSI B 175.1.

S Front Hand Guard, designed to reduce the
chance of your left hand contacting thechain
if your hand slips off the front handlebar .
S Position of front and rear handlebars, de-
signed with distance between handles and
“in-line” with each other . The spread and“in-
line” position of the hands provided by this
design work together to give balance and re-
sistance in controlling the pivot of the saw
back toward t he operator if kickback o ccurs.
CHAIN BRAKE AND CKA ANGLE
S Chain Brake, designedto stopthe chain in
the event of k ickback.
WARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS-
SUME THA T THE CHAIN BRAKE WILL
PROTEC T YOU IN THE EVE NT OF A KICK-
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
canalsobecausedbypinchingthesawchain
along the top of the guide bar. This action may
push t he guide bar r apidly b ack toward th e op-
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 RELY
UPON AN Y O F TH E D E VI CES BUI LT I NTO
YOUR SAW. YOU SHOULD USE THESAW
PROPERL Y AND CAREFULL Y TO A VOID
KICKBACK. Re duced--kickback guid e b ars
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 chain brake should be made by anautho-
rized servicing dealer . Take your unit to the
place of purchase if purchased from a servic-
ing dealer, or to the near est authorized master
service dealer .
S Tip contactin some casesmay cause a light-
ning fast reverse R EACTION, kicking guide
bar up and back toward 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
devices built into your saw.
WARNING: C omputed kickback
angle (CKA) listedon yoursaw and listed in the
CKA table below represents a ngle of kickback
your bar and chain combinations will have
when tested in accordance with CSA (Cana-
dian Standards Association) and ANSI stan-
dards. Wh en purchasing replacement b ar 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 indicate total
energy andangle associated without activation
of the chain brake during kickback. Activated
angle represents chain stoppingtime relative to
activation angle of chain break and resulting
kick angle of saw . In all cases lower CKA val-
ues represent a safer operating environment
for the user .
The f ollowing guide bar and chain combina-
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
standard.
