wedges, but never steel or iron wedges.
S Be alert to signs that the tree is ready to
fall: cracking sounds, widening of the fell-
ing cut, or movement in the upper
branches.
S As treestarts to fall,stop saw,put itdown,
and get away quickly on your planned re-

CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fallen
tree to the desired log size.
WARNING: Donotstandonthelog
being cut. Any portion can roll causing loss
of footing andcontrol. Donot stand downhill
of the log being cut.
IMPORTANT POINTS
S Cut only one log at a time.
S Cut shattered wood very carefully; sharp
pieces ofwoodcould beflung toward opera-
tor .
S Use a sawhorse to cut small logs. Never
allow another person to hold the log while
cuttingandneverholdthelogwithyourleg
or foot.
S Do not cut in an area w here logs, limbs,
and roots are tangled such as in a blown
downarea. Dragthe logsintoacleararea
before cutting by pulling out exposed and
cleared logs first.
TYPES OF CUTTING USED FOR
BUCKING
WARNING: If saw becomes
pinched or hung in a log, don’t try to force it
out. Youcanlosecontrolofthesawresulting

Use a wedge to remove pinched saw
Turn saw OFF and use a plastic or
wooden wedge to force cut open.
Overcutting begins on the top side of the log
with the bottom of the saw against the log.
When overcutting use light downward pres-

The saw will tend to push back toward you.
WARNING: Neverturnsawupside
down to undercut. The saw cannot be con-
trolled in this position.
Always make your first cuton thecompres-

the log is where the pressure of the log’s
weight is concentrated.

BUCKING WITHOUT A SUPPORT
S Overcut t hrough 1/3 of the diameter of the
log.
S Roll the log over and finish with a second
overcut.
S Watch for logs with a compressionside to
prevent the saw from pinching. See il-
lustrationsforcuttinglogswithacompres-
sion side.
BUCKING USING A LOG OR
SUPPORT STAND
