1. When bucking and felling operations are being performed by
two or more persons at the same time, the felling operations
should be separated from the bucking operation by a distance
of at least twice the height of the tree being felled. 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
make contact with any utility line, the company should be notied
immediately.
2. The product operator should keep on the uphill side of the terrain
as the tree is likely to roll or
slide downhill after it is felled.
3. 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 (Fig. 9a).
4. 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.
5. Remove dirt, stones, loose bark, nails, staples and wire from the
tree.

6. Notching undercut
Make the notch (Fig. 9b, B) 1/3 the diameter of the tree,
perpendicular to the direction of falls (Fig. 9b). Make the lower
horizontal notching cut rst. This will help to avoid pinching either the
saw chain or the guide bar when the second notch is being made.
