FELLING LARGE TREES
(6 inches in diameter or larger)
The notch method is used to fell large
trees. A notch is cut on the side of the tree
in the desired direction of fall. After a felling
cut is made on the opposite side of tree,
the tree will tend to fall in the direction of
the notch.
NOTE: If tree has large buttress roots,
remove them before making the notch. If
using saw to remove buttress roots,
keep saw chain from contacting ground
to prevent dulling of the chain.
NOTCH CUT AND FELLING TREE
S Make notch cut by cutting the top of the
notch first. Cut through
diameter of the tree. Next complete the
notch by cutting the bottom. See illustra-
tion. Once the notch is cut, remove the
wedge of wood from tree.

S After removing the wood from the notch,
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 fal-
ling in the wrong direction.
Hinge holds tree on stump and
helps control fall.

NOTE: Before felling cut is complete,
use wedges to open the cut when
necessary to control the direction of fall.
To avoid kickback and 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.
S As tree starts to fall, stop saw, put it
down, and get away quickly on your
planned retreat path.

with partially fallen trees that may be
poorly supported. When a tree doesn't
fall completely, set saw aside and pull
down tree with a cable winch, block and
tackle, or tractor.

S Do not cut in an area where logs, limbs,
and roots are tangled. Drag logs into a
clear area before cutting them by pulling
out exposed and cleared logs first.
BUCKING TECHNIQUES
WARNING:
pinched or hung in a log, don't try to force it
out. You can lose control of the saw result-
ing in injury and/or damage to the saw.
Stop the saw, drive a wedge of plastic or
wood into the cut until the saw can be re-
moved easily. Restart the saw and care-

Turn saw OFF and use a plastic or
wooden wedge to force cut open.
Overcutting begins on the top side of the
log with the bottom of the saw against the
log. When overcutting use light downward
pressure.
