S Study the natural conditions that can cause

Natural conditions that can cause a tree to
fall in a particular direction include:
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
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 help prevent
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
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.

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

NOTE: Before felling cut is complete, use
wedges to open the cut when necessary to
controlthedirectionoffall. Toavoidkickback
and chain damage, use wood or plastic
wedges, but never steel or iron wedges.

cracking sounds, widening of the felling cut,
or movement in the upper branches.

FELLING LARGE TREES

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.
S DO NOT cut down a partially fallen tree
withyour saw. Beextremely cautious with
partially fallen trees that may be poorly
supported. When a tree doesn’t fall com-
pletely,setthesawasideandpulldownthe
