C. BUCKING
Bucking is the term used for cutting a fallen tree to the
desired log size.
1. IMPORTANT POINTS
a. Cut only one log at a time.
b. Cut shattered wood very carefully. Sharp
pieces of wood could be flung toward the
operator.
Use a sawhorse to cut small logs. Never
allow another person to hold the log while cut­
ting and never hold the log with your leg orfoot.
Give special attention to logs under strain
to prevent the saw from pinching. Make the
first cut on the compression side to relieve the
stress on the log. (Figure 31)
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 cut­
ting by pulling out exposed and cleared logs

f- Make the first bucking cut 1/3 of the way
through the log and finish with a 2/3 cut on
the opposite side. As the log is being cut, it
will tend to bend. The saw can become
pinched or hung in the log if you make the first
cut deeper than 1 /3 of the diameter of the log.
TYPES OF CUTTING USED Figure 32.
— Overcutting - begin on the top side of the
log with the spur against the log: exert light
pressure downward.
—Undercutting ~ begin on the under side of the
log with the top of the saw against the log; exert
light pressure upward. During undercutting,
the saw will tend to push back at you. Be pre­
pared for this reaction and hold the saw firmly
to maintain control
WARNING!
If saw becomes pinched or hung in a log, don’t try
to force it out. You could lose control of the saw re­
sulting in personal injury and/or damage to the
saw. Stop the saw and drive a wedge of plastic,
wood of light alloy into the cut until saw can be re­
moved easily. Figure 33. Do not use a steel or iron
wedge to avoid kickback and chain damage.
3. BUCKING—WITHOUT A SUPPORT
a. Overcut with a 1/3 diameter cut.
b. Roll log over and finish with an overcut.
4. BUCKING —USING ANOTHER LOG AS A
SUPPORT (Figure 34):
WARNING!
Do not stand on the log being cut. The cut portion
will roll down hill.
a. In area A:
1. ) Undercut 1 /3 of the way through the log.
2. ) Finish with an overcut.
b. In area B:
1. ) Overcut, 1 /3 of the way through the log.
2. ) Finish with an undercut.
WARNING!
Never turn the saw upside down to undercut. The
saw cannot be controlled in this position.
