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.

planned and cleared as necessary before

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 cut 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
