“in-line” position of the hands provided by
this design work together to give balance
and resistance in controlling the pivot of
the saw back toward the operator if kick-
back occurs.

W ARNING:
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 becaused by allowing contact o fthebar
tip in the danger zone with any hard object.
Kickback canalso becausedby pinchingthe
sawchainalongthetopofthe guidebar. This
action may push the guide bar rapidly back
toward the operator. Either of thes e events
may cause you to lose control of the saw
which could result in serious injury or even
death. DO NOT RELY U PON ANY OFTHE
DEVICES BUILT INTO YOUR SAW. YOU
SHOULD USETHE 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 recom-
mended. Yoursaw hasa low kickback chain
and baras original equipment. Repairs on a
chain brake should b e 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.

Pinching th e saw chain along t he top of the

Either of these reactions may cause you t o
lose control of the saw which could re sult in
serious injury. Do not rely exclusively upon
d evices bu ilt into yo ur saw.
WARNING:
Computed kickback
angle (CKA) listed o n you r saw an dlisted in t he
CKA table below represents angle of kickback
your bar and chain combinations will have
when teste d in acco r d ance with C SA (C ana-
dian Standa rds Association) and ANSI stan-
dards. When purchasing replacement bar and
chain, considerations should be given to the
lower CKA values. L ower CKA values repre-
sent safer angles to the user , higher values in-
dicate more angle and higher kick energies.
Computed angles represented indicate total
energy and a ngle associated withoutactivation
of the chain brake during kickback. Activated
angle r epresents chain stoppingtime relative to
activation angle of chain break and resulting
kick angle of saw . In a ll cases lower CKA val-
ues represent a safer operating environment
for the user.
The following guide bar and chain combina-
tions meet kickback requirements of CSA
Standards Z62.1, Z62.3, & ANSI B175.1 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 req uirements pe r standa rd.
