Notching Undercut - Make the notch
1/3 the diameter of the tree, perpendic-
ular to the direction of fall as illustrated.
Make the lower horizontal notching cut
first. This will help to avoid pinching of
either the saw chain or the guide bar
when the second notch is being made.
Felling Back Cut - Make the felling
back cut at least 2 inches (50.8mm)
higher than the horizontal notching cut
as illustrated. Keep the felling back cut
parallel to the horizontal notching cut.
Make the felling back cut so enough
wood is left to act as a hinge. The hinge
wood helps the tree from twisting and
falling in the wrong direction. Do not cut
through the hinge.
As the feeling cut gets close ot the
hinge the tree should begin to fall. If
there is any chance that the tree may
not fall in the desired direction or it may
rock back and bind the saw chain, stop
cutting before the felling back cut is
complete and use wedges of wood,
plastic or aluminum to open the cut and
drop the tree along the desired line of
fall.
When the tree begins to fall, remove the
chain saw from the cut, stop the motor,
put the chain saw down, then use the
retreat path planned. Be alert for over-
head limbs falling and watch your foot-
ing.
Hinge holds tree on stump and helps
control fall.

NOTE: Before felling cut is complete,
use wedges to open the cut when
necessary to control the direction of fall.
To avoid kickback and chain damage,
use wood or 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 up-
per branches.
• As tree starts to fall, stop saw, put it
down, and get away quickly on your
planned retreat path.
• Be extremely cautious with partially
fallen trees that may be poorly sup-
ported. When a tree doesn't fall com-
pletely, set the saw aside and pull
down the tree with a cable winch,
block and tackle, or tractor. Do not
use your saw to cut down a partially
fallen tree.
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
• It is important to make sure your foot-
ing is firm and your weight is evenly
distributed on both feet. When pos-
sible, the log should be raised and
supported by the use of limbs, logs or
blocks.
• Cut only one log at a time.
