Bucking is the term used for cutting a fallen
tree to the desired log size,
1. IMPORTANT POINTS
Cut only one log at a time.
Cut shattered wood veiy carefolly. 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 cutting and
never hold the log with your leg or foot.
Bo not cut in an area where logs, limbs, and
roots are tangled such as in a blown down
area. Bre^ the logs into a clear area before cut­
ting by pulling out exposed and cleared logs first.
Make the first buckihg cut 1/3 of the way
through the log and HmsH 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
himg in the log if you make the firet 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 21.
2. TYPES OF CUTTING USED {Figure 22):
— Overcutting — begin on the top side of the log
with the bottom of me saw against the log; exert
light pressure downward.
— Undercutting—begin on the imder side of the
log with the top of the saw against the log; exert
li^t pressure upward. During undercutting, the
saw will tend to push back at you. Be prepared for
this reaction and hold the saw firmly to maintain
control.
AWARNING
Never turn the saw upside down to undercut. The
sjftw cannot be contr
A WARNING
If saw becomes pinched or hung in a log, don^t try
to forae it out. You can lose control of the saw re­
sulting in i^ury and/or damage to the saw. Stop
thé saw, drive a wedge of plastic or wood into the
cut until the saw canbe removed easily. Figure 23.
Réstart the saw and carefully reenter thè eut. To
avoid kickback and chain damage, do not use a
metal wedge. Do not attem]pt to restart your saw
when it is pinched or hung m a log.
3. BUCKING WITHOUT A SUPPORT
a. Overcut with a 1/3 diameter cut.
b, Roll log over and finish with an overcut.
