NOTE: Before felling cut is complete, use
wedges to open the cut ff 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 fell-
ing cut. or movement in the upper
branches.
• As tree starts to fall, stop saw, put it down,
and get away quickty on your planned re-
treat path
• DO NOT cut down a partially failen tree with
your saw. Be extremely caubeus with par-
flally fallen trees that may be beody sup-
ported. When a tree doesn't falI completely,
set the saw aside and pull down the tree with
a cable winch, block and tackle, or tractor
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting afallen
tree to the desired log size
A4_WARNING: Do not stand on thelog
being cut Any portion can roll causing loss
of footing and control. Do not stand downhil_
of the log being cut.
IMPORTANT POINTS
• CUt onty one log at a time.
• Cut shattered wood very carefully; sharp
pieces of wood could be flung toward opera-
toe
• Use a sawhorse to cut smaII Iogs. 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 pulliog out exposed and
cleared logs first.
TYPES OF CUTTING USED FOR
BUCKING
AqLWARNING: If saw becomes
pinched or hung in a log, don't try to force it
out. You can Iose control ofthe saw res ulting
in injury and/or damage to the saw. Stop the
saw, drive a wedge of plasfic or wood into the
cut untiI the saw can be removed easiIy. Re-
start the saw and carefully reenter the cut. To
avoid kickback and chain damage, do not
use a metalwedge. Do not attempt to restart
your saw when itis 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
Overcutgng begins on the top side of the log
with the bottom of the saw against the log
When overcutfiog use _ight downward pres-
sure.
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 firmty and maintain control
The saw will tend to push back toward you.
_WARNING: Neverturnsawogside
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 Iog
Second cut
Second cut
First cut on compression side of log
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. Bee il-
Iustrabens 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 illustraflons below for your
first and second cut)
