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 carefuilyl 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 logwhile cut-
ting and never holdthe logwith your leg orfoot.
d. Give special attention to logs under strain
to prevent the saw from pinching. Make the
first cut Onthe compression side to relieve the
stress on the log. (Figure 31)
e. Do not cut in an area where logs, limbs and
roots are tangled such as in a blown down
area. Drag the logs intoa clear area before cut-
ting by pulling out exposed and cleared togs

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
cutdeeper than 1/3of the diameter ofthe log.
2. TYPES OF CUTTING USED Figure 32.
-- Overcutting - begin on the top side of the
log with the spur against the log: exert light
pressure downward.
m Undercutting - begin on the under side ofthe
logwith the top ofthe 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
tomaintain control.
WARNING!
If saw becomes pinched or hungin a log, don't try
to force it out. You could lose control of the saw re-
sulting in personal injury and/or damage to the
saw. Stop the saw and driveawedge ofplastic,
wood orlight alloy into the cut until'saw can be re-
moved easily. Figure 33. Do not use a Steel or iron
wedge to avoid kickback and chain damage,
3. BUCKING--WITHOUT A SUPPORT

will roll down hill.
