• Chain Brake: designed to stop the
chain in the event of kickback.
,_ILWARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS-
SUME THAT THE CHAIN BRAKE WILL
PROTECT YOU 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. Kick-
back 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 saw chain along
the top ofthe guide bar. This action may
push the guide bar rapidly back toward
the operator. Either ofthese events may
cause you to lose control of the saw
which could result in serious injury or
even death. DO NOT RELYUPON ANYOF
THE DEVICES BUILT INTO YOUR SAW.
YOU SHOULD USE THE SAW PROPERLY
AND CAREFULLY TO AVOID KICKBACK.
Reduced-kickback guide bars and low-
kickback saw chains reduce the chance
and magnitude of kickback and are rec-
ommended. Your saw has a low kick-
back chain and bar as original equip-
ment. Repairs on a chain brake should
be made by an authorized Sears Service

• Tip contact in some cases may cause
a lightning fast reverse REACTION,
kicking guide bar up and back toward
operator.
• Pinching the saw chain along the top
of the guide bar may push the guide
bar rapidly back toward the operator.
• Either of these reactions may cause
you to lose control of the saw which
could result in serious injury. Do not
rely exclusively upon safety devices
built into your saw.
,_ 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 (Canadian Stan-
dards Association) standards. When
purchasing replacement bar and chain,
considerations should be given to the
lower CKA values. Lower CKA values
represent safer angles to the user, high-
er values indicate more angle and high-
er kick energies. Computed angle repre-
sented indicates total energy and angle
associated without activation of the
chain brake during kickback. In all cases
lower CKA values represent a safer op-
erating environment for the user.
The following guide bar and chain com-
binations meet kickback requirements
of CSA Z62.1 & Z62.3 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.

SAFETY NOTICE: Exposure to vibra-
tions through prolonged use of gasoline
powered hand tools could cause blood
vessel or nerve damage in the fingers,
hands, and joints of people prone to
circulation disorders or abnormal swell-
ing. Prolonged use in cold weather has
been linked to blood vessel damage in
otherwise healthy people. If symptoms
occur such as numbness, pain, loss of
strength, change in skin color or texture,
or loss of feeling in the fingers, hands, or
joints, discontinue the use of this tool
and seek medical attention. An anti-vi-
bration system does not guarantee the
avoidance of these problems. Users
who operate power tools on a continual
and regular basis must closely monitor
their physical condition and the condition
of this tool.
