NOTE: Before felling cut is complete, use
wedges to open the cut if necessary to
controlthe directionoffall. To avoidkickback
and chain damage, use wood or plastic
wedges, but never steel or iron w edges.
S Be alert to signs that the tree is ready to
fall: cracking sounds, widening of the fell-
ing cut, or movement in t he upper
branches.
S As tree starts to fall, stop saw, put it down,
and get away quickly on your planned re-
treat path.
S DO NOT cut down a partially fa llen tree with
your saw . Be extremely cautious with par-
tially fallen trees that may be poorly sup-
ported. When a t ree doesn’t fall 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 u sed for cutting a fallen
tree to the desired log size.
WARNING: Do notstand on the log
being cut. Any portion can roll causing loss
of footing and control. D o 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 of wood could be flung toward opera-
tor .
S Use a sawhorse to cut small logs. Never
allow another person to hold the log while
cutting and nev er holdthe logwith your leg
or foot.
S 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
WARNING: If saw bec omes
pinched or hung in a log, don’t try to force it
out. Youcan losecontrol ofthe saw resulting
in injury and/or damage to the saw . Stop the
saw, drive awedge ofplastic orwood intothe
cut until the sa w can b e r emoved easily. Re-
startthe sawand ca refully r eenterthe cut. To
avoid kickback and chain damage, do not
use a metal w edge. Do notattempt 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 theunder-
side of the logwith top of saw against thelog.
When undercutting use light upward pres-
sure. Hold saw firmly and maintain control.
The saw will tend to push back t oward you.
WARNING: Never turn saw upside
down to undercut. The saw cannot be con-
trolled in this position.
Always make your fir st cut on the compres-
sion side ofthe log. Thecompression sideof
the log is where the pressure of the log’s
weight is concentrated.
Second cut
First cut on compression side of log
First cut on compression side of log
Second cut
BUCKING WITHOUT A SUPPORT
S Overcut through 1/3 of the diameter of the
log.
S Roll the log over and finish with a second
overcut.
S Watch for logs with a compression side to
prevent the saw from pinching. See il-
lustrations for cutting logs with acompres-
sion side.
BUCKING USING A LOG OR
SUPPORT STAND
S Remember your first cut is always on the
compression side of the log.
(Refer to the illustrations below for your
first and second cut)
S Your first cut should extend
1/3 of the
diameter of the log.
S Finish with your second cut.
