CUTTING
A FALLEN
TREE
(BUCKING)
Bucking is the term used for cutting a fall-
en tree to the desired log size.
WARNING:
Do not stand on the log be-
ing cut. Any portion can roll causing loss of
footing and control. Do not stand downhill
of the log being cut.
IMPORTANT
POINTS
Cut only one log at atime.
Cut
shattered
wood
very
carefully;
sharp pieces of wood could be flung to-
ward operator.
Use asawhorse to cut small logs. Never
allow another person
to hold the log
while cutting
and never hold the log
with your leg or foot.
Do not cut in an area where logs, limbs,
and roots
are tangled
such as in a
blown down area. Drag the logs into a
clear area before cutting
by pulling out
exposed
and cleared logs first.
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 be-
come pinched or hung in the log if you
make the first cut deeper than 1/3 of the
diameter of the log.
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.
TYPES
OF CUTTING
USED
FOR
BUCKING
WARNING:
If sew 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. Restart
the saw and carefully
reenter the cut.
To
avoid kickback
and chain damage, do not
use a metal wedge.
Do not attempt to re-
start your saw when it is pinched or hung in
a log.
Overeutting
begins on the top side of the
log with the bottom of the saw against the
log. When overcutting
use light downward
pressure.
Undercutting
involves
cutting
on the un-
derside of the log with top of saw against the
log. When undercutting
use light upward
pressure.
Hold saw firmly and maintain
control. The saw will tend to push back to-
ward you.

Never
turn
