Feiiing is the term for cutting down a tree. Smaii trees up
to 6-7 inches (15-18cm) in diameter are usuaiiy cut in a
singie cut. Larger trees require notch cuts. Notch cuts
determine the direction the tree wiii faii.
WARNING:
and cleared as necessary before cuts are
started, The retreat path should extend back
and diagonally to the rear of the expected
line of fall, as illustrated in Fig, 12,
NOTE: Direction of fail (B) is controlled by the notching
cut, Before any cuts are made, consider the loca-
tion of larger branches and natural ban of the tree
to determine the way the tree wiii fail.

notched. When felling, keep at bast 2 tree
lengths away from your fellow workers.
Make the felling cut (D) from the other side of the tree and
1.5 - 2.0 inches (3-5 cm) above the edge of the notch (C)
(Fig. 13).

the area for bystanders, animals or obstacles.
Insert a wedge or felling lever in the cut well before the
tree becomes unstable and starts to move, This wiii pre-
vent the guidebar from binding in the feiiing cut if you
have misjudged the falling direction, Make sure no
bystanders have entered the range of the falling tree
before you push it over.
Felling Cut:
1. Use wooden or piastic wedges (G) to prevent binding
the bar or chain (H) in the cut, Wedges also control
felling (Fig, 14),
2. When diameter of wood being cut is greater than the
bar iength, make 2 cuts as shown (Fig, 15),
wures; notify the utility company
g any cuts.
Normally felling consists of 2 main cutting operations,
notching (C) and making the felling cut (D) (Fig, 13),
Start making the upper notch cut (C) on the side of the
tree facing the felling direction (E). Be sure you don t make
the lower cut too deep into the trunk (Fig, 13).
The notch (C) should be deep enough to create a hinge (F)
of sufficient width and strength, The notch should be wide
enough to direct the fail of the tree for as long as possible
(Fig. 13).
