SAWING

Always follow the safety regulations. The chain saw must only be used for cutting wood. It is

forbidden to cut other types of material vibrations and kickback vary with different materials and the

requirements of the safety regulations would not be respected. Do not use the chain saw as a lever for

lifting, moving or splitting objects.

It is not necessary to force the saw into the cut. Apply only light pressure while running the engine

at full throttle.

When the saw chain is caught in the cut, do not attempt to pull it out by force, but use a wedge or

a lever to open the way.

FELLING A TREE

1. Decide the felling direction. Consider the

wind, lean of the tree, location of heavy

branches, and ease of completing the task

after felling and other factors.

2. While clearing the area around the tree,

arrange a good foothold and retreat path.

3. Make a notch cut one-third of the way into

the tree on the felling side.

4. Make a felling cut from the opposite side of

the notch and at a level slightly higher than

the bottom of the notch.

BUCKING AND LIMBING

Always ensure your foothold. Do not stand on the log.

Be alert to the rolling over of a cut log. When working on a slope, stand on the uphill side of the

log.

Follow the instructions in “Operation” to avoid kickback of the saw.

Before starting work, check the direction of bending force inside the log to be cut. Always finish cutting

from the opposite side of the bending direction to prevent the guide bar from being caught in the cut.

A log laying on the ground

A log hanging off the ground

In area A, saw up from the bottom one- third

and finish by sawing down from the top. In

area B, saw down from the top one-third and

finish by sawing up from the bottom.

Before you fell a tree, warn all
bystanders of the danger.

Saw down halfway, then roll the log over

and cut from the opposite side.
