common cutting techniqueS
fellInG
Felling is the process of cutting down
a tree. Be sure battery is fully charged
before felling a tree so you can finish on a
single charge. Do not fell trees in high wind
conditions.

injury. It should only be performed by a
trained person.
• (figure k) A retreat path should be
planned and cleared as necessary before
cuts are started. The retreat path should
extend back and diagonally to the rear of
the expected line of fall.

• Before felling is started, consider the
natural lean of the tree, the location of
larger branches and the wind direction to
judge which way the tree will fall. Have
wedges (wood, plastic or aluminum)
and a heavy mallet handy.
Remove dirt, stones, loose bark, nails,
staples, and wire from the tree where the
felling cuts are to be made.
• (figure l) Notching Undercut - Make
the notch 1/3 of the diameter of the tree,
perpendicular to the direction of the fall.
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.
• (figure l) Felling Back Cut - Make the
felling back cut at least
2 inches (51mm) higher than the
horizontal notching cut. 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 keeps the tree from
twisting and falling in the wrong direction.
Do not cut through the hinge.
• (figure l) As the felling cut gets close to
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 cut is complete and use
wedges to open the cut and drop the tree
along the desired line of fall. When the
tree begins to fall remove the chainsaw
from the cut, stop the motor, put the
