SLow--Kickback Chain, designed with a
contoured depth gauge and guard link
which deflect kickback force and allow
woodto gradually rideinto 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 specified
in ANSI B175.1.

SFront Hand Guard, designed to reduce the
chanceof your left hand contacti ng thechain
if your hand slips off the front handlebar.
SPosition 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 gi ve balance
and resistance in controlling the pivot of
the saw back toward the operator if kick-
back occurs.
CHAIN BRAKE AND CKA ANGLE
SChain 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 fas t 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 can also be caused by pinching the
sawchain along the top of the guide bar. This
action may push the guide bar rapidly back
toward the operator. Either of these events
may cause you to lose control of the saw
which could result in serious injury or even
death. DONOT RELY UPON ANY OF THE
DEVICES BUILT INTO YOUR SAW. YOU
SHOULDUSE THE SAW PROPERLY AND
CAREFULLY TO AVOID KICKBACK. Re-
duced--kickback guide bars and low--kick-
back saw chains reduce the chance and
magnitude of kickback and are rec om-
mended. Your saw has a low kickbac k 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.
STipcontact in some cases may cause a light-
ning fast reverse REACTION, kicking 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 you to
lose control of the saw which could result in
serious injury. Do not rely exclusively upon
devices built into your saw.
WARNING: Computed kickback
angle(CKA) listed on your saw and listed in the
CKAt able 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 replacementbar 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
energyand angle associated without activation
of the chain brake during kickback. Activated
anglerepresents chain stopping time relati ve 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 following guide bar and chain combina-
tions meet kickback requirements of CSA
StandardsZ62.1, Z62. 3, & ANSI B175.1when
usedon saws listed in t his manual. Use of bar
andchain combinat ions othert han thoselist ed
is not recommended and may not meet the
CKA requirements per standard.
