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 ata 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 tohold the log while cut-
tingand never hold thelog withyour leg orfoot.
d. Do not cut in an area where logs, limbs and
roots are tangledsuch as in a blown down
area, Drag thelogs intoa clear area before cut-
ting 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 ifyou make the first
cutdeeper 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 onthe log. Figure28.

Undercutting - begin on the under side ofthe tog
with the top of the saw against the fog; exert light
pressure upward. During undercutting, the saw
will tend topush bac k at you, Be prepared for this
reaction and hold the saw firmly to maintain con-
