• After
removing
the wood ftom
the notch,
make the felling cut on the opposite side of
the notch. This is done by making a cut about
two inches h_gher than the center
of the
notch.
This wilI leave enough uncut wood
between the felling cut and the notch to form
a hinge. This hinge w{ll help prevent the tree
from fa_ling in the wrong direction.

CUTTING
A FALLEN
TREE
(BUCKING)
Bucking
is the term used for cutting a falien
tree to the desired
log size.
_,WARNING:
Donot standonthelog
being 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 Iog at a time.
• Cut shattered
wood very carefully;
sharp
pieces of wood could be flung toward oper-
ator.
• Use a sawhorse
to cut small logs.
Never
allow another
person to hold the log while
cutting and never hold the fog with your teg
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 pul}ing out exposed
and
cleared
logs first.
TYPES

USED
FOR
BUCKING
_'WARNING:
ff saw becomes
pinched or hung in a Iog, 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, dr_ve a wedge of p}astic or wood into the
cut until the saw can be removed easily
Re-
start the saw and carefully reenter the cut. To
avoid
kickback
and chain damage,
do not
use a metalwedge.
Do not attempt to restart
your saw when it is pinched or hung in a log.
Use a wed
e 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 tog
with the bottom
of the saw against
the log.
When overcutting
use light downward
pres-
sure.
Overcutting
Undercutting
Undercutting
involves
cutting on the under-
side of the log with top of saw against the log.
When
undercutting
use light upward
pres-
sure.
Hold saw firmly and maintain
control.
The saw will tend to push back toward you.
_
WARNING:
Never turn saw upside
down to undercut.
The saw cannot be con-
trolled in this position.
AIways
make your first cut on the compres-
sion side of the log. The compression
side of
the log is where
the pressure
of the log's
weight is concentrated.
