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
• 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, make the
felling cut on the opposite
side of the
notch. This is done by making a cut
about two inches higher than the
Centre of the notch. This will leave
enough
uncut wood between
the fell-
ing cut and the notch to form a hinge.
This hinge will help prevent the tree
from falling in the wrong direction.

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, widen-
ing of the felling cut, or movement
in
the upper 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.
CUTTING
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 roots are tangled. Drag logs
into a clear area before cutting them.
BUCKING
TECHNIQUES
_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.
Overcutting
Undercutting
Undercutting
involves cutting on the
underside
of the log with top of saw
against the log. When undercutting
