FELUNG LARGE TREES
(6 inches in diameter or-larger)
The notch method is used to fell large
trees. A notch is cut onlhe 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 dL!llingof the chain.
NOTCH CUT AND FELLING 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 cutting the bottom. See
illustration. Once the notch is cut, re-
move the wedge of wood from tree.

• After removing the wood from the
notch, make the felling cut on the op-
posite 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.
Hinge holds tree on

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.
• Be alert to signs that the tree is ready
to fall: cracking sounds, widening of
the felling cut, or movement in the up-
per branches.
• As tree starts to fall, stop saw, put it
down, and get away quickly on your
planned retreat path.
DO NOT use your saw to cut down a
partially fallen tree. Be extremely
cautious with partially fallen trees
that may be poorly supported. When
a tree doesn't fall completely, set the
saw aside and pull down the tree
with a cable winch, block and tackle,
or tractor.
CU'I'FING
A FALLEN
TREE
(BUCKING)
Bucking is the term used for cutting a
fallen tree to the desired log size.
_, WARNING:
Do not stand on the
log being cut. Any portion can roll
causing loss of footing and control. Do
not stand downhill of the log being cut.
IMPORTANT POINTS
• Cut only one log at a time.
• Cut shattered wood very carefully;
sharp pieces of wood could be flung
toward operator.
• 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.
• Do not cut in an area where logs,
limbs, and rootsare tangled. Drag logs
into a clear area before cuttingthem
by pullingout exposed and cleared
logs first.
BUCKING TECHNIQUES
_k WARNING:
If saw becomes
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 saw and carefully reenter the cut.
Do not use a metal wedge. Do not at-
tempt to restart your saw when it is
pinched or hung in a log.
Use a wedge to remove pinched saw
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.
