FELLING LARGE TREES
(6 inches in diameter or larger)
Thenotch method is used to fell large trees.
A notch is cut on the sid e of the tree in the
desired direction of fall. After afelling cut is
made on the opposite side of tree, the tree
will tend to fall into the notch.
NOTCH CUT AND FELLING THE TREE
SMake notch cut by cutting the top of the
notchfirst. Cut through 1/3 of the diameter
of the tree. Next complete the notch by
cutting the bottom of the notch. See il-
lustration. Once the notch is cut remove
the notch of wood from the tree.
SAfter removing the cutout of 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 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
thetree from falling in the w rong direction.

NOTE:Before felling cut is complete, use
wedges to open the cut when necessary to
control the direction of fall. Use wood or
plastic wedges, but never steel or iron, to
avoid kickback and chain damage.
SBe alert to signs that the tree is ready to
fall:cracki ng sounds,widening of the fell-
ing cut, or movement in the upper
branches.
SAstree starts to fall, stop saw, put it down,
andget away quickly onyour planned re-
treat path.
SBeextremely cautious with partially fallen
trees that may be poorly supported.
When a tree doesn’t fall completely, set
thesaw aside and pull down the tre e with
acable winch, block and tackle, or tractor.
Toavoid injury,do not cut down a partially
fallentreewithyoursaw.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fall-
en tree to the desired log length.
WARNING: Do not stand on the logbe -
ing cut. Any portion can roll causing loss of
footing and control. Do not stand downhill
of the log being cut.
Important points
SCut only one log at a time.
SCut shattered wood very carefully; sharp
pieces of wood could be flung toward op-
erator.
SUse a sawhorse to cut small logs. Never
allowanother person to hold the log while
cutting and never hold the log with your
leg or foot.
SDo not cut in an areawhere logs, limbs,
androots are tangled. Drag the logs into a
cleararea before cutting by pulling out ex-
posed and cleared logs first.
TYPES OF CUTTING USEDFOR BUCKING
WARNING: If saw becomes pinched or
hung in a log, don’t try to force it out. You
canlose control of the saw resulting in injury
and/or damage to the saw.Stop the saw,
drivea wedge of plastic or wood into the cut
untilthe saw can be removed easily. Restart
thesaw and carefully ree nter the cut. Do not
attempt to restart your saw when it is
pinched or hung in a log.
Overcutting begins on the top side of the
logwith the saw against the log. When over-
cutting use light downward pressure.
Overcutting
Undercutting
Undercutting involves cutting on the un-
dersideof the log with top of saw against the
log. When undercutting use light upward
pressure. Hold saw firmly and maintain con-
trol. The saw will tend to push back toward
you.
WARNING: Never turn saw upside
down to undercut. The saw cannot be con-
trolled in this position.
