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 togs. Never
allow another person to hold the log while cut-
tingand never holdthe logwithyour legorfoot
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 20.
e. Do not cut in an area where logs, limbs and
roots are tangled such as in a blown down
area. Pulloutexposed andclearedlogsfirst.Drag
the logsintoa clear area before cutting.
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 logisbeingcut, itwilltend

the log ifyou make the firstcut deeper than 1/3 of
the diameter fo the log.

injury and/or damage to the saw. Stop the saw,
drive a wedge of plastic or wood into the cut until the
saw can be removed easily. Figure 23. 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 itispinched or hung
