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 u ncut wood
between the felling cut and the not ch to form
a h inge. 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
controlthe directionof fall. Toavoid kickback
or chain damag e, use wood or plastic
wedges, but never steel or iron wedges.
S Be alert to signs that the tree is ready to f all:
cracking sounds, widening of the felling cut,
or movement in the upper branches.
S As tree starts t o fall, stop saw, put itdown,
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 par-
tially fallen trees that may be poorly sup-
ported. When a tree doesn’t fall completely,
set t he saw aside and p ull down t he 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 length.
WARNING: Do not stand on the log
being cut. Any portion can roll causing loss
of f ooting 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 ofwood could beflung towardoper-
ator.
S Use a sawhorse to cut small logs. Never
allow another person to hold the log while
cutting and never hold thelog with your leg
or foot.
S Do not cut in an area where logs, limbs,
and roots are tangled. Drag t he logs intoa
clear area before cutting b y pulling out ex-
posed and cleared logs first.
TYPES OF CUTTING USED FOR
BUCKING
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 thesaw can be removed easily. Restart
the saw and carefully ree nterthe cut. Do not
attemptto restart yoursaw whenit is pinched
or hung in a log.
Turn saw OFF and use a plastic or
wooden wedge to force cut open.
Overcutting begins onthe topsideof thelog
with the saw against the log. When overcut-
ting use light downward pressure.
