TREE FELLING TECHNIQUES
WARNING: Check forbrokenordead
branches which can fall while cutting causing
serious injury. Do not cut near buildings or
electrical wires if you do not know the direction
of tree fall, at night since you will not be able to
see well, or during bad weather such as rain,
snow, or strong winds, etc. If tree makes con-
tact 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 After removing the wood from the notch,
makethefelling cuton theopposite sideof
the notch. This is done by making a cut
about two inches higher than the center of
the notch. This will leave enough uncut

the tree from falling in the wrong direction.
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
sloping terrain. Use a plumb or level to de-
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.
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.

and wire from the tree where cuts are to be
made.
