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 logwith your legor fool
do Do not cut in an area wheretogs, limbs and
roots are tangled such as in a blown down
area. Drag the logsintoaclear area befo_'ecut-
ting by pulling out exposed and cleared logs
first.
e. Make the first bucking cutt/3 of theway

will tend to bend, The saw can become
pinched or hung inthe log ifyou make the first
:.cut deeper than 1/3of the diameter ofthe fog.
•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. Figure28.
2. TYPES OF CUTTING USED (Figure 29)
Overcutting - begin on the top side of the log
with the bottorn of the saw against the log;
exert light pressure downward.
;..:, . WARNING!
Never turn the saw ;upside down to undercut. The
saw cannot be controlled in this position.
-- Undercutting - begin on the under side of the log
with the top,ofthe saw against the log; exert light
.: pressure upward. During undercutting, the, saw
willtend topush back at you. Be prepared for this

WARNING]
If saw becomes pinched or hung in a log, don't try
to force it out. You could lose control ofthe saw re-
suiting in personal injury and!or damage to the
saw. Stop the saw and drive a wedge of plastic,
wood or light alloy into the cut until saw can be re-
moved easily. Figure 30. Do not use a steel or iron
wedge to avoid kickback andchain damage.
