TREE FELLING TECHNIQUES
NOTCH CUT AND FELLING THE
TREE
S Make notch cut by cutting the top of the
notch first. Cut through 1/3 of the diameter
ofthetree.Nextcompletethenotchbycut-
ting the bottom of the notch. See illustra-
tion. Once the notch is cut remove the
notch of wood from the tree.
WARNING:
Check for broken or
dead branches which can fall while cutting
causingserious injury. Donotcutnearbuild-

will not be ale to see well, nor during bad
weather suchas rain, snow,or strongwinds,
etc. If the tree makes contact with any utility
line, the utility company should be notified
immediately.

S Study the natural conditions that can cause
the tree to fall in a particular direction.
Natural conditions that can cause a tree to
fall in a particular direction include:
S The wind direction and speed.
S The lean of the tree. The lean of a tree
might not be apparent due to uneven or
slopingterrain. Useaplumb or level tode-
termine the direction of tree lean.
S Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. If the trunk is rotted, it
can snap and fall toward the operator. Check
for broken or dead branches which can fall on
you while cutting.
Make sure there is enough room for the treeto
fall. Maintain a distance of 2-1/2 tree lengths
from the nearest person or other objects. En-
gine noise can drown out a warning call.
Second cut
Hinge
S After removing the cutout of wood, make
the felling cut on the opposite side of the
notch. This is done by making a cut about
twoinches (5cm) higher thanthe center of
the notch. This will leave enough uncut
woodbetweenthefellingcutandthenotch
to form a hinge. This hinge will help pre-
