C.BUCKING

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 log while cut- ting and never hold the log with your leg or foot.
d.Give special attention to logs under strain to prevent the saw from pinching. Make the first cut Onthe compression side to relieve the

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
cut deeper than 1/3 of the diameter of the 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 of the log with the top of the saw against the log; exert
light pressure upward. During undercutting,
the saw will tend to push back at you. Be pre-OVERCUT
pared for this reaction and hold the saw firmly to maintain control.
WARNING!
If saw becomes pinched or hungin a log, don'ttry 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,
