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)
Buokh_g 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 _ogat a time.
Cut shattered wood very carefully; sharp
pieces of wood could be flung toward oper-
ator.
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 such as in a blown
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
_)AWARNING: if saw becomes
pinched or hung in a log, don't try to force it
out, You can lose control ofthe saw resulting
in injury and/or damage to the saw. Stop the
saw, drive a wedge of plastic or wood h3to the
cut until the saw can be removed easily. Re-
start 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.
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.
_k 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,
First cut on compression side of log
Second cut
Second cut
First cut on compression side of tog
BUCKING WITHOUT A SUPPORT
Overcut through 1/3 of the diameter of the
log=
Roll the log over and finish with a second
overcut,
Watch for logs with a compression side to
prevent the saw from pinching, See iF
lustrations for cutting logs with a compres-
sion side.
BUCKING USING A LOG OR
SUPPORT STAND
Remember your first cut is always on the
compression side of the log, (Refer to the
illustrations below for your first and second
cut)
Your first cut should extend t/3 of the
diameter of the log,
Finish with your second cut.
Using a log for support
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.
