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.

Low--Kickback Chain, designed with a

contoured depth gauge and guard link

which deflect kickback force and allow

wood to gradually ride into the cutter. Low--

Kickback Chain has met kickback per-

formance requirements when tested on a

representative sample of chain saws be-

low 3.8 cubic inch displacement specified

in 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 handle-

bar.

Position 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 give balance

and resistance in controlling the pivot of

the saw back toward the operator if kick-

back occurs.

Chain Brake, designed to stop the chain in

the event of kickback.

CHAIN BRAKE AND CKA ANGLE

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 by allowing contact of the bar

tip in the danger zone with any hard object.

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 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 OF THE

SAFETY DEVICES BUILT INTO YOUR

SAW.

YOU SHOULD USE THE SAW

PROPERLY AND CAREFULLY TO AVOID

KICKBACK. Reduced--kickback guide bars

and low--kickback saw chains reduce the

chance and magnitude of kickback and are

recommended. Your saw has a low kick-

back chain and bar as original equipment.

Repairs on a chain brake should be made by

an authorized servicing dealer. Take your

unit to the place of purchase if purchased

from a servicing dealer, or to the nearest au-

thorized master service dealer.

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 and ANSI standards. When purchasing

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 angles

represented in the non-activated 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.

Tip contact in some cases may cause a

lightning fast reverse REACTION, kicking

the guide bar up and back toward the oper-

ator.

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 control of the saw which could result

in serious injury.Do not rely exclusively

upon the safety devices built into your saw.

The following guide bar and chain combina-

tions meet kickback requirements of CSA

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 requirements per standard.
