Low--Kickback Chain, designed with a
contoured depth gauge and guard link
which deflect kickback force and allow
wood to gradually ride into the cutter.Low--
Kickback Chain has met kickback per-
formance requirements when tested on a
representative sample of chain saws be-

in ANSI B175.1.

Front Hand Guard, desi gned to reduce the
chance ofyour left handcontacting 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 o f 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.
CHAIN BRAKE AND CKA ANGLE
S
Chain Brake, designed to 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. Kickback
can be caused by allowing contact of the bar
tip in the danger zone with any hard object.
Kickback canalso becaused bypinching the
sawchain along thetop ofthe guidebar. This
action may push the gui de bar rapidly back
toward the operator. Either of these events
may cause you to lose control of the saw
which could result i n serious injury or even
death. DO NOTRELY UPON ANY OFTHE
DEVICES BUILT INTO YOUR SAW. YOU
SHOULD USE THE SAWPROPERLYAND
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 sawhas 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.

Pinching the sawchain along the top ofthe

Either of these reactions maycause youto

in serious injury.Do not rely exclusively
upon thesafety devices built into yoursaw.
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 and ANSIstandards. Whenpurchasing
replacement 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. C omputed angles
represented in the non-activated column in-
dicate total energy and angle associated
without 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.
The following guide bar and chain combina-
tions meet kickback requirements of CSA
Z62.1, Z62.3, & ANSI B175.1 when used on
saws l isted 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.

NOTE:
If this saw is to be used for commer-
cial logging, a chain br ake isrequired and shall
not be removed or otherwise disabled to com-
ply with Federal O SHA R egulations for Com-
mercial Logging.
SAFETY NOTICE:
Exposure to vibrations
through prolonged use of gasoline pow ered
hand tools could cause blood vessel or nerve
damage in the fingers, hands, and joints of
people prone to circulation disorder s or
abnormal swellings. Prolonged use in c old
weather has been linked to blood vessel
damage in otherw ise healthy people. If
