SFrontHand Guard, des igned to reduce the
chance of your left hand contacting the
chain if your hand slips off the front handle-
bar.
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 fastac-
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 kic kback 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.
WARNING: Computed kickback
angle (CKA) listed on your sawand lis ted in
the CKA tabl e below represents angle of
kickback your bar and chain combinati ons
will have when tested in accordance with
CSAand A NSI standards. When purchasing
replacement bar and chain, considerations
should be given to the lower CKA values.
Lower CKAvalues representsafer angles to
the user, higher values indic ate more angle
and higher kickenergies. Com puted angles
represented in the non-activated column in-
dicate total energy and angle associated
without activation of the chai n brake during
kickback. Activated angle represents chain
stopping time relative to activation angle of
chain brake and resulting kick angle of saw.
In all cases lower CKA values represent a
safer operating environment forthe user.
STip contact in some cases may cause a
lightning fast reverse REACTION, kicking
theguide bar up and back toward the oper-
ator.
SPinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back toward the operator.
SEither of these react ions may cause you to
lose control of the saw which could result
in serious injury.Do not rely exclusiv ely
uponthe saf ety devices built into your s aw.
The following guide bar and chain combina-
tions meet kickback requirements of CSA
Z62.1, Z62.3, & ANSI B175.1when used on
saws listed in this manual. Use of bar and
chain combinations other than those li sted is
not recommended and may not meet the
CKA requirements per standard.
