S
DO NOT cut down a partially fallen t ree
with your saw. Be extremely cautious with
partially fallen trees that may be poorly
supported. When a tree doesn’t fall com-
pletely, setthe sawaside and pull down the
tree with a cable winch, block and tackle,
or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fallen
tree to the desired log size.
WARNING:
Do not stand on the log
being cut. Any portion can roll causing loss
of footing and control. Do not 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 of woodcould be flung toward oper-
ator.
S
Use a sawhorse t o cut small logs. Never
allow another person to hold the log while
cutting and never hold the log with yourleg
or foot.
S
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.
TYPES OF CUTTING USED FOR
BUCKING
WARNING:
If saw becomes
pinched or hung in a log, don’t try to force it
out. Youcan lose control of the sawresulting
in injury and/or damage to the saw. Stop the
saw, drive awedge of plastic orwood into the
cut until the saw can be removed easily. Re-
start the sawand carefully reenter thecut. 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.
Use a wedge to remove pinched saw
Turn saw OFF and use a plastic or
wooden wedge to force c ut open.
Overcutting begins on the top side of the l og
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 t o undercut. The s aw cannot be con-
trolled in this position.
Always make your first cut on the compres-
sion side of the log. The compression side of
the l og is where the pressure of the log’s
weight is concentrated.

prevent the saw from pinching. See il-
lustrations for cutting logs with acompres-
sion side.
