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 carefiilly. Sharp
pieces of wood could be flung toward the opera­
tor.
c. Use a sawhorse to cut small logs. Never al­
low another person to hold the log while cutting
and never hold the log with your leg or foot.
d. 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 £irea be­
fore cutting by pulling out exposed and cleared
logs first.
e. 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.
f. Give special attention to logs under strain
to prevent the saw from pinching. Make the
first cut on the pressure side to relieve the stress
on the log. Figure 22 .
2. TYPES OF CUTTING USED (Figure 23 ):
— Overcutting — begin on the top side of the
log with the bottom of the^saw 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 Ught pressure upward. During undercut­
ting, the saw will tend to
pus A back at you. Be
prepared for this reaction and hold the saw firm-
ly to maintain control.
A WARNING
Never turn the saw upside down to imdercut. The
saw cannot be controlled in this position.
A WARNING
If saw becomes pinched or hung in a log, donH try
to force it out. Yon can lose control of the saw re<
suiting in injury and/or damage to the saw. Stop
the saw, drive a wedge of plastic or wood into the
cut ruitil the saw can be removed easily. Fig­
ure 24 . 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 m a log. ______________
3. BUCKING WITHOUT A SUPPORT
Overcut with a 1/3 diameter cut. a.
b. Roll log over and finish with an overcut.
