6. Sawing

•Before proceeding to your job,

read the section “For Safe Operation”. It is recommended to first practice sawing easy logs. This also helps you get accustomed to your unit.

• Always follow the safety regu- lations. The chain saw must only be used for cutting wood. It is forbidden to cut other types of material. Vibrations and kickback vary with differ- ent materials and the require- ments of the safety regulations would not be respected. Do not use the chain saw as a le- ver for lifting, moving or split- ting objects. Do not lock it over fixed stands. It is forbidden to hitch tools or applications to the PTO other than those specified by the manufacturer.

•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.

•If the guide bar and saw chain becomes caught in wood while operating it, stop the engine.

Do not pry the handle with excessive force. Use a wedge to remove the chain instead.

■FELLING A TREE

Felling direction

Notch cut Felling cut

1.Decide the felling direction considering the wind, lean of the tree, location of heavy branches, 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.

When you fell a tree, be sure to warn neigh- boring workers of the danger.

Bucking and Limbing

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

•Be alert to the rolling over of a cut log. Es- pecially when working on a slope, stand on the uphill side of the log.

•Follow the instructions in “For Safe Opera- tion” 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 lying on the ground

Saw down halfway, then roll the log over and cut from the opposite side.

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 bot- tom.
