1. Before using chain saw, review the Safety instructions listed in this Manual and be

aware of local regulations covering the operation of your saw.

2. For all types of cutting always hold the saw firmly in both hands, with thumbs

fingers encircling the handles. (FIG. 25).

3. Ensure work area is clear, and that you have firm footing.

4. When cutting through the log, reduce the cutting pressure near the end of the cut

without relaxing your grip on the chain saw to maintain complete control.

5. After completing cut, allow saw chain to stop before moving saw, or moving to

another tree.

GENERAL CUTTING INSTRUCTIONS

Felling

1. When felling and,bucking operations are being performed by two or more persons at

the same tinrie, the felling operation should be separated from the bucking operation

by a distance of at least twice the height of the tree being felled.

2. Trees should not be felled in a manner that would endanger any person, strike any

utility line or cause any property damage. If the tree does contact a utility

line notify the utility company without delay.

3. Before felling is started clear your retreat path diagonally away from the expected line

of the fall. (FIG. 6).

4. Remove dirt, stones, loose bark, nails, staples and wirefrom thetreewherethefelling

cuts are to be made.

5. Notching Undercut should be 1/3 the thickness of the tree at right angles to the

direction of the fall (FIG. 26).

6. Make the horizontal notching cut first, to help avoid pinching of saw. chain or

guide bar when the second notching cut is made.

Felling back cut. Should be 2" above the horizontal notching cut. (FIG. 26). Do not cut

through the hinge which will stop the tree from twisting and falling in the wrong

direction.

As the felling back cut nears the hinge, the tree should begin to fall. If the tree tends to

rock backwards, to avoid pinching the guide bar and chain use hard wedges to hold the

cut open and drop the tree in the right direction. When the tree begins to fall, withdraw

the chain saw from the cut, release the trigger, put the saw down and retreat along the

planned path; Be alert for over limbs dropping and watch your footing.

Limbing, Leave the large lower limbs to support the trunk of the tree on the ground.

Remove other limbs in preparation for bucking the trunk to required lengths. (FIG. 31).

Note: Limbs under load will pinch and trap the guide bar if cut from the inside. Always

cut from the outside.
