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 authorized

servicing dealer. Take your unit to the place of

purchase if purchased from a servicing 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.

S

Pinching the saw chain along the top of the

guide bar may push the guide bar rapidly

back toward the operator.

S

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.

CHAIN BRAKE

S

Chain brake, designed to stop the chain in

the event of kickback.

WARNING

:

Your chain saw is

equipped with a chain brake that is designed to

stop the chain immediately if you get a kick-

back. The chain brake reduces the risk of acci-

dents, but only you can prevent them. DO NOT

ASSUME THAT THE CHAIN BRAKE WILL

PROTECT YOU IN THE EVENT OF A KICK-

BACK.

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

symptoms occur such as numbness, pain,

loss of strength, change in skin color or

texture, or loss of feeling in the fingers,

hands, or joints, discontinue the use of this

tool and seek medical attention. An

anti-vibration system does not guarantee the

avoidance of these problems. Users who

operate power tools on a continual and

regular basis must monitor closely their

physical condition and the condition of this

tool.

ASSEMBLY

Protective gloves (not provided) should be

worn during assembly.

ATTACHING THE BUMPER

SPIKE

The bumper spike may be used as a pivot

when making a cut.

1. Loosen and remove the chain brake nuts

and the chain brake from the saw.

2. Attach the bumper spike with the two

screws as illustrated.

ATTACHING THE BAR & CHAIN

(If

not already attached)

WARNING

:

Recheck each assem-

bly step if the saw is received assembled. Al-

ways wear gloves when handling the chain.

The chain is sharp and can cut you even

when it is not moving!

1. Loosen and remove the chain brake nuts

and the chain brake from the saw.

2. Remove the plastic shipping spacer (if

present).

3. An adjusting pin and screw is used to ad-

just the tension of the chain. It is very im-

portant when assembling the bar, that the

pin located on the adjusting screw aligns

into a hole in the bar. Turning the screw will

move the adjustment pin up and down the

screw. Locate this adjustment before you

begin mounting the bar onto the saw. See

illustration below.

Chain Brake

4. Turn the adjusting screw by hand coun-

terclockwise until the adjusting pin just

touches the stop. This should allow the

pin to be near the correct position.

5. Slide guide bar behind clutch drum until

guide bar stops against clutch drum

sprocket.
