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 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 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

CAREFULLY 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.
S

Tip contact in some cases may cause a light-

ning fast reverse REACTION, kicking the

guide bar up and back toward the 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 the 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. Prolonged use in cold

weather has been linked to blood vessel

damage in otherwise healthy people. If
