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.
c. 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 or foot.
d. 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 25)
e. Do not cut in an area where logs, limbs and
roots are tangled such as in a blown down
area. Drag the logsinto a clear area before cut-
ting by pulling out exposed and cleared logs
first,
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.
2. TYPESOFCUTTING USED Figure26.
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.
z_WARNING I
Never turn the saw upside down to undercut. The
•saw cannot be controlled in this position.
z_WARNING
If saw becomes pinched or hung in a log, don't try to
force it out. You san lose control of the saw resulting in
personal Injury and/ordamage to the saw. Stop the saw,
drive a wedge of plastic or wood into the cut until the
saw can be removed easily. Figure 27. Restart the saw
and carefully reenter the cut. Do not use a metal 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,
