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 orfoot.
d.
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 20.
e.
Do not cut in an area where logs, limbs and
roots are tangled such as In a blown down
area.
Pull out exposed and cleared logs first. Drag
the logs into a clear area before cutting.
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 fo the log.
2. TYPES OF CUTTING USED
Figure 21.
—Overcutting -
begin on the top side of the log
with the spur against the log; exert light pres
sure downward.
— Undercutting -
begin on the underside of the log
with the spur against the log; exert light pressure
upward. During undercutting, the saw will tend to
push back at you. Be prepared forthis 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. You can lose control of the saw resulting in
injury and/or damage to the saw. Stop the saw,
drive a wedge of plastic or wood into the cut until the
saw can be removed easily. Figure 23. 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.
