S Chain Brake: designed to stop the
chain in the event of kickback.
WARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT ASSUME
THAT THE CHAIN BRAKE WILL PROTECT
YOU IN THE EVENT OF A KICKBACK.
Kick-
back is a lightning fast action which throws
the bar and rotating chain back and up to-
ward 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 saw chain 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 con-
trol of the saw which could result in serious
injury or even death.
DO NOT RELY UPON
ANY OF THE SAFETY 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 re-
duce the chance and magnitude of kick-
back and are recommended. Your saw
has a low kickback chain and bar as origi-
nal equipment. Repairs on a chain brake
should be made by an authorized Sears
Service Centre. Take your unit to the place
of purchase or to your nearest Sears Ser-
vice Centre.
S Tip contact in some cases may cause
a lightning fast reverse
REACTION ,
kicking guide bar up and back toward
operator.
S Pinching the saw chain along the top
of the guide bar may push the guide
bar rapidly back toward the operator.
S 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 and 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.
SPECIAL NOTICE: Your saw is
equipped with a temperature limiting
muffler and spark arresting screen which
meets the requirements of California
Codes 4442 and 4443. All U.S. forest
land and the states of California, Idaho,
Maine, Minnesota, New Jersey, Oregon,
and Washington require by law that
many internal combustion engines be
equipped with a spark arrestor screen. If
you operate a chain saw in a state or
