6. Sawing

WARNING

•Before proceeding to your job,

read the section “For Safe Op- eration”. It is recommended to first practice sawing easy logs. This also helps you get accus- tomed 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 lever for lifting, moving or splitting ob- jects. 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.

■GUARD AGAINST KICKBACK

•This saw is equipped with a chain brake that will stop the chain in the

event of kickback if operating prop- erly. You must check the chain brake operation before each usage by run- ning the saw at full the throttle for I - 2 seconds and pushing the front hand guard forward. The chain should stop immediately with the en-

gine at full speed. If the chain is slow

 

to stop or does not stop, replace the

 

brake band and clutch drum before

 

use.

G

• It is extremely important that the

chain brake be checked for proper

B

operation before each use and that

 

the chain be sharp in order to main-

 

tain the kickback safety level of this

 

saw. Removal of the safety devices,

 

inadequate maintenance, or incor-

 

rect replacement of the bar or chain

 

may increase the risk to serious per-

 

sonal injury due to kickback.

 

■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.

WARNING

•When you fell a tree, be sure to warn neighboring workers of the danger.

Bucking and Limbing

WARNING

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

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

•Follow the instructions in “For Safe 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.
