• Low-Kickback Chain, designed with a con-
toured depth gauge and guard link which de-
flect kickback force and allow wood to gradu-
ally ride into the cutter, Low-Kickbeck Chain
has met kickback performance require-
ments when tested on a representative sam-
pie of chain saws below 3.8 cubic inch
displacement specified in ANSI Bt75.1.

• Front Handguard, designed to reduce the
chance of your left hand contacting the chain
if your hand slips off the front handlebar,
• Position 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 give balance and re-
sistance in controlling the pivot of the saw
back toward the operator if kickback occurs.
CHAIN BRAKE
• 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 can also be caused by pinching the
Computed kickback angle (CKA) Table
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 control of the saw
which could result in serious injury or even
death. DO NOT RELY UPON ANY OF THE
DEVICES BUILT INTO YOUR SAW. YOU
SHOULD USE THE SAW PROPERLY AN D
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 saw has a low 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.
• 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 controi of the saw which could result
in serious injury. Do not rely exclusively
upon safety devices built into your saw.
_L, 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
CBA and ANSI 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, higher values indicate more angle
and higher kick energies. Computed angles
represented in the non-activated column in-
dicate total energy and angte associated
without activation of the chain brake during
kickback. Activated angle represents chain
stopping time relative to activation angte 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 listed in this manual. Use of bar and
chain combinations other than those tisted is
not recommended and may not meet the
CKA requirements per standard.
