3-5. SAW CHAIN TENSION

ADJUSTMENT

Proper tension of the saw chain is extr

emely important and must be checked

before starting, as well as during, any

cutting operation. Taking the time to

make needed adjustments to the saw

chain will result in improved cutting

performance and prolonged chain life.

NOTE: A new chain and bar will need

readjustment after as few as 5 cuts.

This is norma! during the break-in

period, and the interval between future

adjustments will lengthen quickly

(Figure 3-5A),

CAUTION

It a chain is TOO LOOSE or TOO

TIGHT, the bar chain and saw bearings

will wear more rapidly.Study Figure

3-5A for information concerning correct

co!d tension (A), correct warm tension

(B), and as a guide tor when saw chain

needs adjustment (C).

TO ADJUST SAW CHAIN

TENSION:

1. Loosen the bar retaining nuts (D) so

they are hand tight. (See Fig.3-5B)

2. Holding the nose of the bar up, use

the screwdriver or scrench if

provided in your User’s Kit to turn

the guide bar adjustment screw (E)

(Fig.3-5C) clockwise to tighten the

chain.Turning the screw COUNTER

CLOCKWISE LOOSENS THE

CHAIN on the guide bar.

3. After adjustment and while wearing

heavy duty work gloves, move the

saw chain back and forth on the

guide bar to be sure the chain

moves freely and is in proper mesh

with sprocket.Do not move chain

with bare hands.

NOTE:IF the chain is difficult to rotate

or if it binds on the guide bar, too much

tension has been applied and must be

adjusted.To decrease tension, turn the

adjustment screw counterclockwise

slowly.Move the chain back and forth

until it moves freely.

A. Holding the nose in upper position,

securely tighten the bar retaining

nuts (70 inch lbs.)

3-6. ASSEMBLY OF POLE SAW

1. Make sure the unit is unplugged

from power source,

2. Slip handle bracket (A) over chain

saw handle (B) from the right side

cket will go onto the handle. Push

the lock-off button and depress the

trigger. While holding the trigger in,

place the trigger support portion of

the bracket under the trigger and
