A good preventive maintenance program of regular inspection and care will increase life and improve performance of

your chain saw. This maintenance checklist is a guide for such a program.

Cleaning, adjustment, and part replacement may be required, under certain conditions, at more frequent intervals than

those indicated.

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.

Fig. 13

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.
