Using the chain saw

Always be sure of your footing and hold the chain saw firmly with both hands while the motor is running.

Felling a tree

When bucking and felling operations are being performed by two or more persons, a t the same time, the felling operation should be separated from the bucking operation by a distance of a t least twice the height of the tree being felled. Trees should not be felled in

amanner that would endanger any person, strike any utility line or cause any property damage. If the tree does make contact with any utility line, the utility company should be notified immediately.

The chain saw operator should keep on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled.

A retreat path should be planned and

 

cleared as necessary before cuts are started.

Retreat

The retreat path should extend back and

diagonally to the rear of the expected line

 

of fall as shown in Fig. 16.

Direction of fall

- -

Before felling is started, consider the natural lean of the tree, the location of larger branches and the wind direction to judge which way the tree will fall. Remove dirt, stones, loose bark, nails, staples, and wire from the tree where felling cuts are to be made.

Notching undercut

Make the notch 1/3 the diameter of the tree, perpendicular to the direction of fall as shown in Fig. 17. Make the lower horizontal notching cut first. This will help to avoid pinching of either the saw chain or the guide bar when the second notch i s being made.
