£ Remove dirt, stones, loose bark, ii^^, sta­
ples, and wire from the tree where cuts are
to be made.
g^. Plan to stand on the up-hill side when cut­
ting on a slope. Figure 17.
h. Plan a clear retreat path to the rear and di­
agonal to the line of fall. Figure IS.
FEtONG SMALL TREES--LESS THAN
6” IN DIAMETER
If you know the direction of fall:
1. ) Make a single felling cut on the side away from
the direction of fall.
2. ) Cut all the way through,
3. ) Stop the saw, put it down, and get away quickly
on your planned retreat path.
If you are not sure which way the tree will fall, use
the notch method described for felling large trees.

DO NOTCIJK A WARNING
—near electrical wires or buildings.
--if you do not know the direction of tree fall.
--St night since you will not be able to see well.
—during bad weather — rain, snow, strong
wind, etc.
3. FELLING LARGE TREES—6” IN DIAMETER
OR MORE
The notch method is used to fell largje 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
them before making the notch. Cut into the but­
tresses vertically, then horizontally. Figure 19,
a. Make the notch cut. Figure 19 .
1. ) Cut the bottom of the notch first, througdi 1/3
of the diameter of the tree.
2. ) Complete the notch by niaking the slant cut.
3. ) Remove the notch of wood.
Make the felling cut on the opposite side of the
notch about 2” higher than the bottom of the
notch.
Leave enough uncut wood between the felling cut
and the notch to form a hinge. Figure 20.
NOTE; The hinge helps to keep the tree from twist­
ing and falling in the wrong direction,
d. Use a wed№ if there is any chance that the tree
will not fall in the desired direction.

A WARNING
Stay on thè uphill side of the terrain to avoid in­
jury from the tree rolling or sliding downhill af­
ter it is felled. Figure 18 .
NOTE; Before the felling cut is complete, use wedges
to open the cut when necessary to control the direc­
tion of fall. Use wood or plastic wed^s, but never
steel or iron, to avoid kickback and chain damagCr
e. Be alert to signs that the tree is ready to fall:
1. ) Cracking sounds,
2. ) ^dening of the Felling Cut.
^ 3.) Movement in the upper branches.
f. As tree starts to fall, stop thesaw,piait doiun^ and
vei away quickly on your planned retreat path.
g. Be extremely cautious "mth partially fallen trees
that msy 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
taclde, or tractor. To avoid ixquiy, do not cut down
a partially fallen tree with your saw.________
