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.
S DO NOT use your saw to cut down a par-
tially fallen tree. Be extremely cautious
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.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fall-
en tree to the desired log size.
WARNING: Do not stand on the
log being cut. Any portion can roll caus-
ing loss of footing and control. Do not
stand downhill 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 to-
ward operator.
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. Drag logs into a
clear area before cutting them by pulling
out exposed and cleared logs first.
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 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-
fully reenter the cut. 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 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 un-
derside of the log with top of saw against
the log. When undercutting use light up-
ward pressure. Hold saw firmly and main-
tain control. The saw will tend to push
back toward you.
WARNING: Never turn saw upside
down to undercut. The saw cannot be
controlled in this position.
Always make your first cut on the com-
pressions side of the log. The compres-
sion side of the log is where the pressure
of the log’s weight is concentrated.
First cut on compression side of log

BUCKING WITHOUT A SUPPORT
S
Overcut through 1/3 of the diameter of
the log.
S Roll the log over and finish with a sec-
ond overcut.
