2. FELLING SMALL TREES -- LESS THAN
6"IN DIAMETER
a. Ifyou know thedirecUonoffall:
1.) Make a single felling cuton the side away
from thedirection offall.
2.) Cut all theway threugh.
3.) Stop the saw, put it down, and get away
quickly onyourplanned retreat path.
b. Ifyou are not sure which way the tree willfall,
use the notch method described for felling
largetrees.
z_WARNING
DO NOT CUT:
-- near electrical wires or buildings.
-- ifyou do not know the direction of tree fall.
-- at _ight since you will not be able tosee well.
--during bad weather-- strong wind, snow, rain,
etc.
3. 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, re-
move before making the notch. Cut into the but-
tresses Wrtically, then horizontally. Figure22.
a. Make thenotchcut.Figure 23.
f.) 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
Cutand the notch to form a hinge. Figure 24.
NOTE: The hinge helps to keep the tree from
twisting and falling in the wrong direction.
d. Use a wedge ifthere is any chance that the tree
will not fall in the desired direction.

NOTE: Before the felling cut is complete, drive
wedgestoopen upthecutwhen necessarytocon-
trolthedirecf_onoffall. Usewoadorplasticwedges
but never metal, to avoid kickback and chain
damage.
e. Be alert for signs that the tree isready tofall:
t.) crackingsounds
2.) widening of the felling cut
3.) movement in the upper branches,
f. As the tree starts te fall, stop the saw; put it
down, and get away quickly on your planned
retreat path.
g. Be extremely cautious with partially fallen trees
that may be poorly supported. When a tree
doesn't fall completely, set thQ saw aside and
pull down the tree with a cable winch, blockand
tackle ortractor.Do not cutitdownwithyoursaw
toavoid injury.
Check the wind
Don't cut down wind.
DON'T PUT YOURSELF IN THESE POSITIONS
Check the lean
Don't cut on lean side.
Check the balance
Don't cut on weighted side.
