INSTALL THE GUIDE BAR

These instructions are for replaciing a bar. The unit is

fully assembled when shipped.

Note: Always wear heavy gloves when handling the saw

chain.

1. Place the power unit on a flat surface.

2. Loosen knob (B) slightly by turning knob counter-

clockwise and then turn the chain tension ring (C)

counter-clockwise to relieve chain tension (Fig. 17).

3. To remove the sprocket cover (A), turn knob (B)

counter-clockwise. (Fig. 17)

4. Remove saw chain from around the guide bar and

the sprocket. Slide the guide bar, with tension plate

(D) attached, from the unit. (Fig. 18)

5. Remove screw (C) from the tension plate (D) to

remove it from the old bar and attach it to the new

bar. (Fig. 19)

INSTALL THE SAW CHAIN

1. Spread the chain out with the cutting edges (E) of

the chain pointing in the DIRECTION OF ROTATION

(Fig. 20).

2. To fit the chain links into the groove on the guide bar,

turn the tension plate (D) counter-clockwise to the

end. Install the chain and bar on the power unit, turn

the tension plate (D) clockwise and then put the side

cover (A) on (Fig. 21).

3. Turn the knob clockwise, adjust the chain tension

ring (F) and then tighten the knob. See Saw Chain

Tension Adjustment P14.

4. After running the chain saw even for just 1 hour,

retensioning of the chain may be needed. Follow the

tension adjustment instructions in the next section.

Always use

protective gloves

when handling the saw chain.

OPERATING INSTRUCTIONS

LIMBING

Limbing a tree is the process of removing the branches

from a fallen tree. Do not remove supporting limbs (A)

until after the log is bucked (cut) into lengths (Fig. 12).

Branches under tension should be cut from the bottom

up to avoid binding the chain saw.

BUCKING

Bucking is cutting a fallen log into lengths. Make sure

you have a good footing and stand uphill of the log when

cutting on sloping ground. If possible, the log should be

supported so that the end to be cut off is not resting on

the ground. If the log is supported at both ends and you

must cut in the middle, make a downward cut halfway

through the log and then make the undercut. This will

prevent the log from pinching the bar and chain. Be

careful that the chain does not cut into the ground when

bucking as this causes rapid dulling of the chain.

Never cut tree limbs

while standing on a

tree trunk.

WARNING:

When bucking on a slope, always stand on the uphill side.

1. Log supported along entire length: Cut from top

(overbuck), being careful to avoid cutting into the

ground (Fig. 13).

2. Log supported on 1 end: First, cut from bottom

(underbuck) 1/3 diameter of log to avoid splintering.

Second, cut from above (overbuck) to meet first cut

and avoid pinching (Fig. 14).

3. Log supported on both ends: First, overbuck 1/3

diameter of log to avoid splintering. Second, underbuck

to meet first cut and avoid pinching (Fig. 15).

NOTE: The best way to hold a log while bucking is to use

a sawhorse. When this is not possible, the log

should be raised and supported by the limb

stumps or by using supporting logs. Be sure the

log being cut is securely supported.

BUCKING USING A SAWHORSE

For personal safety and ease of cutting, the correct

position for vertical bucking is essential (Fig. 16).

A. Hold the saw firmly with both hands and keep the

saw to the right of your body while cutting.

B. Keep the left arm as straight as possible.

C. Keep weight on both feet.

While the saw is

cutting, be sure the

chain and bar are being properly lubricated.
