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 byallowing contact of the bar
tip in the danger zone with any hard object.
Kickback canalsobecaused bypinching the
sawchainalongthetopofthe guidebar. 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 RELYUPON ANY OFTHE
DEVICES BUILT INTO YOUR SAW. YOU
SHOULDUSE THESAW PROPERLYAND
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. Yoursawhas alowkickback chain
and bar as original equipment. Repairs on a
chain brake should be made by an autho-
rized servicing dealer. Tak e your unit to the
place of purchase if purchased from a ser-
vicing dealer, or to the nearest authorized
master service dealer.
S
Tip contact in some cases may cause a
lightning fast reverse REACTION, kicking
guide bar up and back toward operator.
S
Pinching thesawchain along thetop ofthe
guide bar m ay push the guide bar rapidly
back toward the operator.
S
Either of these reactions maycause youto
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 andANSIstandards. Whenpurchasing
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 angl es
represented in the non-ac tivated column in-
dicate total energy and angle associated
without activation of the chain 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 for the user.
The following guide bar and chain combina-
tions meet kickback requirements of CSA
Z62.1, Z62.3, & ANSI B 175.1 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 s tandard.
