FELLING LARGE TREES
(g 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-
s{red direction of fall. After a fel_ing cut is
made on the opposite side of tree, the tree
wiII 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-
iog of the chain.
NOTCH CUT AND FELLING THE
TREE
• Make notch cut by cutting the top of the
notch first. Cut through 1/3 of the diameter
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 (fel_ing) cut here, 2 inches
(5 cm) above center of notch.

• After remowog the wood from the notch,
make the felling cut on the opposite side of
the notch. This is done by making a cutabout
two inches (5 cm) higher than the center of
the notch This wilt leave enough uncut wood
between the felling cut and the notch to form
a hinge. This hinge w{ll help prevent the tree
from fa_liog in the wrong direction.
Hinge holds tree on stump and helps
control fall
Opening
of felling
• DO NOT cut down a partially fallen tree
with your saw. Be extremely cautious with
partiaIly fallen trees that may be poorly
supported. When a tree doesn't fall com-
pIetely, set the saw aside and pull down the
tree with a cable winch, b}ock and tackle,
or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fal}en
tree to the desired log s_ze.
_ WARNING: Do not stand on theIog
being cut. Any portion can roll causing loss
of footing and control. Do not stand downhill
of the _og being cut.
IMPORTANT POINTS
• Cut only one Iog at a time.
• Cut shattered wood very carefully; sharp
pieces of wood could be flung toward opera-
toe
• Use a sawhorse to cut small logs. Never
atlow another person to hold the log while
cutting and never hold the Iog with your leg
or foot.
• Do not cut in an area where logs, Iimbs,
and roots are tangled such as in a blown
down area. Drag the logs into a clear area
before cutting by pulIiog out exposed and
cleared logs first.
TYPES OF CUTTING USED FOR
SUCKING
_&WARNING: _f saw becomes
pinched or hung in a Iog, don't try to force it
out. You can lose control of the saw resu_tiog
in _njury and/or damage to the saw. Stop the
saw, dr_ve a wedge of p}astic 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
Closing of
notch
NOTE: Before felling cut is complete, use
wedges to open the cut if necessary to
controt the dftection of fall To avoid kickback
and chain damage, use wood or plastic
wedges, but never steel or iron wedges.
• Be alert to signs that the tree is ready to
fall: cracking sounds, widening of the fell-
log cut, or movement in the upper
branches.
• As tree starts to fall stop saw, put it down,
and get away quick}y on your planned re-
treat path
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 overcutt_og use _ight downward pres-
sure
,\_Overcutting
Undercutting',,;
Undercutting involves cutting on the under-
side of the log with top of saw against the log.
When undercutting use light upward pres-
sure. Hold saw firmly and maintain control
The saw will tend to push back toward you.
