Reduced Kickback Symmetrical Guide Bar

Symmetrical Guide Bar

Large Radius Tip

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 AND CKA ANGLE

Chain 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. 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

DEVICES BUILT INTO YOUR SAW. YOU

SHOULD USE THE SAW PROPERLY AND

CAREFULL Y 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. 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 the

place of purchase if purchased from a ser-

vicing dealer, or to the nearest authorized

master service dealer.

Tip contact in some cases may cause a light-

ning fast reverse REACTION , kicking guide

bar up and back towar d operator.

Pinching the saw chain along the top of the

guide bar may push the guide bar r apidly

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

devices built into your saw.

WARNING:

Computed kickback

angle (CKA) listed on your saw and listed in the

CKA table below r epresents angle of kickback

your bar and chain combinations will have

when tested in accordance with CSA (Cana-

dian Standards Association) and ANSI 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 angle and higher kick energies.

Computed angles represented indicate 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 break and resulting

kick angle of saw . In all cases low er C KA 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 requirements per

standard.
