• Reduced-Kickback Guide Bar, designed

with a small radius tip which reduces the
size of the kickback danger zone on the

bar tip. A Reduced-Kickback Guide Bar
has been demonstrated to significantly re­

duce the number and seriousness of kick­

backs when tested in accordance with

safety requirements for gasoline powered
chain saws as set by ANSI B175.1.

• Front Hand Guard, designed to reduce the

chance of your left hand contacting the chain

if your hand slips off the front handiebar.

• Position of front and rear handlebars, de­

signed with distance between handles and
"¡n-line" with each other. The spread and

“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.

CHAIN BRAKE AND CKA ANGLE

• Chain Brake, designed to stop the chain in

the event of kickback.

THE CHAIN BRAKE WILL

PROTECT YOU IN THE EVENT OF A KICK­
BACK. Kickback is a lightning fast action

which throws the bar and rotating ohain back
and tip toward the operator. Kickback can be
caused by allowing contact of the bar tip in frie
danger zone with any hard abject. Kickback
can also be caused by pinching the saw chain
along the top of the guide bar. This action may

push the guide bar rapidly back toward the op­

erator. 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 !NTO

YOUR SAW. YOU SHOULD USE THE SAW

PROPERLY AND CAREFULLY TO AVOID
КЮКВАСК. Reduced-kickback guide bars

and low-kickback saw chains reduce the
chance and magnitude of kickback and are

recommended. 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 tiie
place of purchase if purchased from a servic­
ing dealer, or to the nearest authorized master

service deafer.

• Tip contact in some cases may cause a light­

ning 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 conti'ol of the saw which could result in
serious injury. Do not rely exciusively upon
devices buift into your saw.

A WARNING:

Computed kickback

angfe (CKA) listed on your saw and listed in tine
CKA table below represents angle of kickback
your bar and chain combinations will have
when tested in accordance with CSA (Cana­
dian Standards Association) and ANSf stan­
dards. When purchasing replacement bar and
chain, considerations should be given to the

lower CKA values. Lower CKA values repre­

sent safer angles to the user, higher values in­
dicate more angfe and higher kick energies.
Computed angles represented indicate total
energy and angle associated without activation
of tile chain brake during kickback. Activated
angfe represents chain stopping time relative to
activation angle of chain break and resulting

kick angle of saw. In all 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, ZS2.3, & 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 frie

CKA requirements per standand.
