Notch : "" * __
• 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 falling in the wrong direction.
Hinge holds tree on stump and helps
control fall

NOTE: Before fetling 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 upper branches.
• As tree starts to fall stop saw, put it down,
and get away quickly on your planned re-
treat path.
• DO NOT cut down a partially fallen tree
with your saw. Be extremely cautious with
partially fallen trees that may be poorly
supported. When a tree doesn't fall com-
pletely, set the saw aside and pull down the
tree with a cable winch, block and tackle,
or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Buckh_g is the term used for cutting a fallen
tree to the desired log size.
i_ 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 _og at a time.
• Cut shattered wood very carefully; sharp
pieces of wood could be flung toward opera-
tor.
• Use a sawhorse to cut small logs. Never
allow another person to hold the log while
cutting and never hold the tog with your leg
or foot.
• Do not cut in an area where logs, limbs,
and roots are tangled such as in a btown
down area. Drag the logs into a clear area
before cutting by pulling out exposed 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 itout. 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. Restart the saw
and carefully reenter the cut. To avoid kickback
and chain damage, 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 pres-
sure.
Overcutting Undercutting
Undercutting involves cutting on the under-
side of the log with top of saw against the log.
When undercutting use light upward pres-
sure. Hold saw firmly and maintain control.
The saw will tend to push back toward you.
_L, WARNING:
Never turn saw upside
down to undercut. The saw cannot be con-
trolled in this position.
Always make your first cut on the compres-
sion side of the log. The compression side of
the log is where the pressure of the log's
weight is concentrated.
