S Practice cutting a few small logs using the
following techniques to get the“feel” ofus-
ing your saw before you begin a major
sawing operation.
FELLING LARGE TREES
(15
cm in diameter or larger)
The notch method is used to fell large trees.

sired direction of fall. After a felling cut is
made on the opposite side of tree, the tree
will tend to fall into the notch.
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

unpredictable.
Carefully plan your sawing operation in ad-
vance. You need a clear area all around the
tree so you can have secure footing. Check
for broken or dead branches which can fall
on you causing serious injury.
Natural conditions that can cause a tree to
fall in a particular direction include:
S The wind direction and speed.
Second cut

After removing the wood from the notch,
make the felling cut on the opposite side of

two inches higher than the center of the
notch. This will leave enough uncut wood
between the felling cut and the notch to form
a hinge. This hinge will helpprevent thetree

S Surrounding trees and obstacles.
Look for decay and rot. If thetrunk 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.
Remove dirt, stones, loose bark, nails, sta-

NOTE: Before felling cut is complete, use
wedges to open the cut when necessary to
controlthedirectionoffall. Toavoidkickback
or chain damage, use wood or plastic
wedges, but never steel or iron wedges.
S Be alert to signs that the tree is ready to fall:
cracking sounds, widening of the felling cut,
or movement in the upper branches.
