FELLING SMALL TREES — LESS THAN 6"
IN DIAMETER
a. If you know the direction of fall:
1. ) Make a single felling cut on the side away
from the direction of fall.
2. ) Cut ail the way through.
3. ) Stop the saw, put it down, and get away
quickly on your planned retreat path.
b. If you are not sure which way the tree will fall,
use the notch method described for felling large
trees.
ikWARNING
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 — strong wind, snow, rain,
etc.
FELLING LARGE TREES — 6' DIAMETER
OR MORE
The notch method is used to cut large 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 the tree, the tree will tend to fall
into the notch.
NOTE: If the tree has large buttress roots, remove
before making the notch. Cut into the buttresses
vertically, then horizontally. Figure 16.
a. Make the notch cut. Figure 18.
1. ) Cut the bottom of the notch first, through 1 /3
of the diameter of the tree.
2. ) Complete the notch by making the slant cut.
3. ) Remove the notch of wood.
b. Make the felling cut on the opposite side of the
notch about 2" higher than the bottom of the
notch.
c. Leave enough uncut wood between the felling
cut and the notch to form a hinge. Figure 19.
NOTE: The hinge helps to keep the tree from
twisting and falling in the wrong direction.
d. Use a wedge if there is any chance that the tree
will not fall in the desired direction.

^WARNING
Stay on the uphill side of the tree to avoid the tree roli-
ing or sliding downhill into you.
NOTE: Before the felling cut is complete, drive
wedges to open up the cut when necessary to con­
trol the direction of fall. Use wood or plastic wedges
but never metal, to avoid kickback and chain
damage.
e. Be alert for signs that the tree is ready to fall:
1. ) cracking sounds
2. ) widening of the felling cut
3. ) movement in the upper branches.
f. As the tree starts to fall, stop the saw; put it
down, and get away quickly on your planned re-
treatpath.
g. Be extremely cautious with partially fallen trees
that may be poorly supported. When a tree
doesn’tfall completely, set the saw aside and pull
down the tree with a cable winch, block and
tackle or tractor. To avoid injury, do not cut down
a partially fallen tree with your saw.
DON’T PUT YOURSELF IN THESE POSITIONS
Check the leari.
Don’t cut on lean side.
