WARNING
DO NOT CUT:
- near electrical wires or buildings.
- if you do not know the direction of tree fall.
- at night since you will not be able to see well.
- during bad weather - rain, snow, strong wind, etc.
2. FELLING TREES
The notch method is used to fell trees. A notch is cut
on the side of the tree in the desired direction of fall.
After a felling cut is made on the opposite side of
tree, the tree will tend to fall into the notch.
NOTE: If the tree has large buttress roots, remove
them before making the notch. Cut into the buttresses
vertically, then horizontally. Figure 20.
a. Make notch cut. then felling cut. Figure 22.
Cut I Cut top of the notch first, through 1/3 of the
diameter of the tree.
Cut 2 Complete the notch by making bottom cut.
Remove the notch of wood.
Cut 3 Make felling cut on opposite side of the
notch about 2" higher than bottom of notch.
b. Leave enough uncut wood between the felling cut
and the notch to form a hinge. Figure 23.
NOTE: The hinge helps to keep the tree from twisL
ing and falling in the wrong direction.
c. U.se a wedge if there is any change that the tree will
not fall in the desired direction.
A
WARNING
Stay on the uphill side of the terrain to avoid injury
from the tree rolling or sliding downhill after it is felled.
Figure 21.
NOTE: Before felling cut is complete, use wedges to
open the cut when necessary to control the direction
of fall. Use wood or plastic wedges, but never steel or
iron, to avoid kickback and chain damage.

d. Be alert to signs that the tree is ready to fall:
1. ) Cracking sounds.
2. ) Widening of the Felling Cut.
3. ) Movement in the upper branches.
e. As tree starts to fall, stop saw, and get away quickly
on your planned retreat path.
f. Be extremely cautious with partially fallen trees
that may be poorly supported. When a tree doesn’t
fall completely, set the saw aside and pull down the
tree with a cable winch, block and tackle, or trac­
tor. To avoid injury, do not cut down a partially
fallen tree with your saw.
