SLow--Kickback Chain, designed with a
contoured depth gauge and guard link
which deflect kickback force and allow
woodto gradually ride into the cutter. Low--
Kickback Chain has met kickback per-
formance requirements when tested on a
representative sample of chain saws be-
low 3.8 cubic inch displacement spec ified
in ANSI B175.1.

SFront Hand Guard, designed to reduce the
chanceof your l eft hand contacting the chain
if your hand slips off the front handlebar.
SPosition of front and rear handlebars , de-
signedwith distance between handles and
“in-line” with each other. Thespread and
“in-line” position of the hands provided by
this design work together to give balance
and resistance in controllingthe pivot of
the saw back toward the operator if kick-
backoccurs.
CHAINBRAKE AND CKA ANGLE
SChainBrake, designed to stop the chain in
theevent of kickback.
WARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS-
SUME THAT THE CHAIN BRAKE WILL
PROTECTYOU IN THE EVENT OF A KICK-
BACK. Kickback is a lightning fast action
which throws the bar and rotating chain back
and up toward the operator. Kickback canbe
causedby al lowing contact of the bar tip in the
danger zone with any hard object. Kickback
canalsobecausedbypinchingthesawchain
along the top of the gui de bar. Thi s action may
pushthe guide bar rapidly back toward the op-
erator. Ei ther of these events may cause y ou
tolose control of thesaw which could result in
serious injury or even death. DO NOT RELY
UPON ANY OF THE DEVICES BUILTINTO
YOURSAW. YOUSHOULD USE THE SAW
PROPERLY AND CAREFULLY TO AVOID
KICKBACK. Reduced --kickbac k guide bars
and low--kickback saw chains reduce the
chance and magnit ude of kickback and are
recommended. Yoursaw has a low ki ckback
chain and bar as original equipment. Repairs
ona chain brake s hould be made by an autho-
rized servi cing dealer. Take your unit t o the
place of purchase if purchased from a servic -
ing dealer, or to the near est authorized mas ter
service dealer.
STipcontactinsome cases maycause a light-
ning fast reverse RE ACTION, kic king guide
bar up and back toward operator.
SPinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back toward the operator.
SEither of these reactions may cause youto
lose control of the saw which could result i n
serious injury. Do not rely exclusively upon
devicesbuilt into your saw.
WARNING: Computed kickback
angle(CKA) l isted on your saw and lis ted in the
CKAtabl e below represents angle of kic kback
your bar and chain combinations will have
whentested in accordancewith 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 val ues repre-
sent safer angles to the user, higher values in -
dicate more angle and higher kick energies.
Computed angles represented indicate total
energyand angle associ atedwi thoutacti vation
of the chain brake during kickback. Ac tivated
anglerepresents chain s topping time relative to
activation an gle of chain break and res ulting
kick angle of saw. In all cases lower CKA val -
ues represent a safer operating environ ment
for the user.
Thefoll owing 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.
