KICKBACK SAFETY FEATURES
WARNING: The followingfeatures
areinc luded ony our saw to help reduce the
hazard of kickback; however, such f eatures
will not totally eliminate this danger. As a
chainsaw us er,do not rely onlyon safety de-
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.
SReduced--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
hasbeen demonstrated t o significantly re-
ducethe number and s eriousness 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
woodto gradually ride into the cutter. Low--

SFront Hand Guard, designed to r educe the
chance of your left hand contacting the chain
if your hand slips off the front handlebar.
SPosition of front and rear handlebars, de-
signedwith distanc ebetween 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 resistance in controlling the pivot of
the saw back toward the operator if kic k-
back occurs.
CHAIN BRAKE AND CKA ANGLE
SChainBrake, designedto stop the chain in
the event of kickback.
WARNING: WE DO NOT REP-
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. Kick back
canbe caus ed by allowing contact of the bar
tip in the danger zone with any hard object.
Kickbackc an also be caused by pinchingthe
sawchain along the top of the guidebar. This
action may push the guide bar rapidly back
toward the operator. Either of these events
may cause you to lose control of the s aw
which could result in serious injury or even
death. DO NOT R ELYUPON A NY OF THE
DEVICES BUILTINTO YOUR SAW. YO U
SHOULDUSE THE SAW PROPERLY AND
CAREFULLY TOAVOID KICKBACK. Re-
duced--kickback guide bars and low--kick-
back saw chains reduce the chance and
magnitude of kickback and are recom-
mended. Yours aw has alow kic kback chain
andbar as original equipment. Repairs ona
chain brake should be made by an autho-
rized servicing dealer. Take your unitt othe
place of purchase if purchased from a ser-
vicing dealer, or to the nearest authorized
master service dealer.
STip contact in some cases may cause a
lightningfast reverse REACTION, kicking
theguide bar up and backtoward the oper-
ator.
SPinchingthe saw c hain along the top of the
guide bar may push the guide bar rapidly
back toward the operator.
SEitherof these reactionsmay cause y ou to
lose control of the saw which could res ult
in serious injury.Do not rely exclusively
uponthe safety devices builtinto your saw.
WARNING: Computed k ickback
angle(CK A) 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(Canadian Standards 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-
catetotal energy andangle assoc iated with-
out activation of the chain brake during
kickback. Activated angle repres ents chain
stopping time relative to activation angle of
chainbr ake and resulting kick angle of saw.
In all cases lower CKA values represent a
safer operating environment for the user.
The followingguide bar and chain combina-
tions meet kickback requirements of CSA
Z62.1,Z62.3, & ANSI B175.1when us edon
saws listed in this manual. Use of bar and
chaincombinations other thanthose listed is
not recommended and may not meet the
CKA requirements per standard.
