FELLING LARGE TREES (6 inches
(15 cm) 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 de-
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.
NOTE:
If the tree has large buttress roots,
remove them before making the notch. If us-
ing saw to remove buttress roots, keep saw
chain from contacting ground to prevent dull-
ing of the chain.
NOTCH CUT AND FELLING THE
TREE
S Make notch cut by cutting the top of the
notch first. Cut through
1/3
of the tree. Next complete the notch by cut-
ting the bottom of the notch. See illustra-
tion. Once the notch is cut, remove the
notch of wood from the tree.
Final cut here. 2 inches above
center of notch.

Second cut
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 pre-
vent the tree from falling in the wrong direc-
tion.

NOTE:
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 re-
treat path.
S DO NOT cut down a partially fallen tree
with your saw. Be extremely cautious with
partially fallen trees that may be poorly
supported. When a tree doesn't fall com-
pletely, set the saw aside and pull down the
tree with a cable winch, block and tackle,
or tractor.

CUTTING A FALLEN TREE

(BUCKING)
Bucking is the term used for cutting a fallen
tree to the desired log size.
WARNING:
being cut. Any portion can roll causing loss
of footing and control. Do not stand downhill
of the diameter of the log being cut.
IMPORTANT POINTS
S Cut only one log at a time.
S Cut shattered wood very carefully; sharp
pieces of wood could be flung toward oper-
ator.
S Use a sawhorse to cut small logs. Never
allow another person to hold the log while
cutting and never hold the log with your leg
or foot.
S Do not cut in an area where logs, limbs,
and roots are tangled such as in a blown
down area. Drag the logs into a clear area
before cutting by pulling out exposed and
cleared logs first.
TYPES OF CUTTING USED FOR
BUCKING
WARNING:
pinched or hung in a log, don't try to force it
out. You can lose control of the saw resulting
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 removed easily. Re-
start the saw and carefully reenter the cut. To
avoid kickback and chain damage, do not
use a metal wedge. Do not attempt to restart
your saw when it is pinched or hung in a log.
Use a wedge to remove pinched saw
Turn saw
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 pres-
sure.
