Hinge
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.

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

to form a hinge.  This hinge will help pre-

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.

control fall
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-
