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 log with your leg ot foot,
d Oo not cut in an area where logs, limbs and
roots are tangled such as in a blown down area.
Drag the logs into a dear area before cutting by pull­
ing 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 if you make the first 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 23.
2. TYPES OF CUTTING USED Figure 24
—Overcutting— begin on the top side of the log with
the bottom of the saw against the log; exert light
pressure downward.
—Undercutting— begin on the under side of the log
with the top of the saw against the fog; exert light
pressure upward.
During undercutting, the saw will tend
to posh back at you. Be prepared for this reaction and hold
the saw firmly to maintain control.
A WARNING
Never turn the saw upside down to undercut. The saw
cannot be controlled in this position.
A WARNING
If saw becomes pinched or hung in a log, don’t try to
force it out. \bu can lose control of the saw resulting in
serious injury and/or damage to the saw. Stopthe
saw, drive a wedge of plastic or wood into the cut
until the saw can be removed easily. Figure 25.
Restart the saw and carefully reenter the cut. To
avoid kickback and chain damage, do not use a
metal wedge. Do not attempt to restart your saw
when it is pinched or hung In a log.
