plastic wedges, but never steel or iron
wedges.
Be alert to signs that the tree is ready to fall:
cracking sounds, widening of the felling cut, or
movement in the upper branches.
As tree starts to fall, stop saw, put it down, and
get away quickly on your planned retreat path.
DO NOT cut down a partially fallen tree with
your saw. Be extremely cautious with partially
fallen trees that may be poorly supported.
When a tree doesn’t fall completely, set the
saw aside 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
Cut only one log at a time.
Cut shattered wood very carefully; sharp
pieces of wood could be flung toward
operator.
Use a sawhorse 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 sure the chain will not strike the ground
or any other object during or after cutting.
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. 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.
Types Of Bucking Cuts
Overcutting 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 underside
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 toward you.
WARNING: Never turn saw upside
down to undercut. The saw cannot be
controlled in this position.
Always make your first cut on the compression
side of the log. The compression side of the log
is where the pressure of the log’s weight is
concentrated.
Bucking Without A Support
1. Overcut through 1/3 of the diameter of the
log.
2. Roll the log over and finish with a second
overcut.
NOTE: Watch for logs with a compression side
to prevent the saw from pinching.
Bucking Using A Log Or Support Stand
1. Make the first cut on the compression side
of the log. Your first cut should extend 1/3 of
the diameter of the log.
2. Finish with your second cut.
