Symmetrical Guide Bar

Large Radius Tip

Low- Kickback Chain, designed with a con-

toured depth gauge and guard link which de-

flect kickback force and allow wood to gradu-

ally ride into the cutter. Low-Kickback Chain

has met kickback performance requir e-

ments when tested on a representative sam-

ple of chain saws below 3.8 cubic inch

displacement specified in ANSI B175.1.

Front Handguar d, designed to reduce the

chance of your left hand contacting the chain

if your hand slips off the front handlebar.

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 re-

sistanc e in contr olling the pivot of the saw

back toward the operator if kickback occurs.

CHAIN BRAKE

Chain Brake, designed to stop the chain in

the event of kickback.

WARNING:

WE DO NOT REP-

RESENT AND YOU SHOULD NOT AS-

SUM E THAT THE CH AIN BRAKE WILL

PROTECT YOU IN THE EVENT OF A KICK-

BACK. Kickback is a lightning fast action

which throw s the bar and rotating chain back

and up towar d 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 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 INTO

YOUR SA W. YOU SHOULD USE THE SAW

PROPERLY AND CAR EFULLY TO AVOID

KICKBAC K. 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 the

place of purchase if purchased from a servic-

ing dealer, or to the nearest authorized master

service dealer.

Tip contact in some cases may cause a

lightning 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 control of the saw which could result

in serious injury. Do not rely exclusively

upon safety devices built into your saw.

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 .

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.

NOTE

: If this saw is to be used for commer-

cial logging, a chain brake is required and shall

not be removed or otherwise disabled to com-

ply with Federal OSHA Regulations for Com-

mercial Logging.

SAFETY NOTICE:

Exposure to

vibrations through prolonged use of gasoline

powered hand tools could cause blood

vessel or nerve damage in the fingers,

hands, and joints of people prone to

circulation disorders or abnormal swellings.
