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.

■

Before any cuts are started, an escape path should

be planned and cleared as necessary before cuts are

started. The escape path should extend back and

diagonally to the rear of the expected line of fall. See

Fig.12.

■

Before felling is started, consider the force and direction

of the wind, the lean and balance of the tree, and the

location of large limbs. These things influence the

direction in which the tree will fall. Do not try to fell a

tree along a line different from its natural line of fall.

■

The chainsaw operator should keep on the uphill side

of the terrain as the tree is likely to roll or slide downhill

after it is felled.

■

Remove dirt, stones, loose bark, nails, staples, and wire

from the tree where felling cuts are to be made.

■

Notched Undercut. Cut a notch about 1/3 the diameter

of the tree, perpendicular to the direction of fall. Make

the cuts of the notch so they intersect at a right angle to

the line of fall. This notch should be cleaned out to leave

a straight line. To keep the weight of the wood off the

saw, always make the lower cut of the notch before the

upper cut. See Fig.13.

■

Felling Backcut. The backcut is always made level and

horizontal, and at a minimum of 50 mm (2 in) above the

horizontal cut of the notch. See Fig.13-14.

■

Never cut through to the notch. Always leave a band of

wood between the notch and backcut (approximately

50 mm (2 in). or 1/10 the diameter of the tree). This is

called "hinge" or "hingewood." It controls the fall of the

tree and prevents slipping or twisting or shoot-back of

the tree off the stump. See Fig.13-14.

■

On large diameter trees, stop the back cut before it is

deep enough for the tree to either fall or settle back on

the stump. Then insert soft wooden or plastic wedges

into the cut so they do not touch the chain. The wedges

can be driven in, little by little, to help jack the tree over.

See Fig.15.

■

As tree starts to fall, stop the chainsaw and put it down

immediately. Retreat along the cleared path, but watch

the action in case something falls your way. Be alert

for overhead limbs or branches that may fall and watch

your footing.

Never cut through to the notch when making a backcut.

The hinge controls the fall of the tree, this is the section

of wood between the notch and backcut.
