has met kickback performance require-
mentswhen tested on a representativesam-
ple of chain saws below 3.8 cubic inch
displacement specified in ANSI B175.1.

SFront Handguard, designed to reduce the

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
designwork together to give balance and re-
sistance in controlling the pivot of the saw
backtoward the operator if kickback occurs.
CHAIN BRAKE
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. Kic kback is a lightning f ast 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
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. DO NOT RELY UPON ANY OFTHE
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. Yoursaw has a low kickback chain
and bar as original equipment. Repairs on a
chain brake should be made by an aut ho-
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.
STip contact in some cases may cause a
lightning fast reverse REACTION, kicking
guide bar up and back toward operator.
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 youto
lose control of the saw which could result
in serious injury. Do not rely exc lusively
upon safety devices built into your saw.
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 represent safer angles to
the user, higher values indic ate more angle
and higher kick energies. Computed 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 for the user.
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.
