COMMON CUTTING TECHNIQUES
FELLING
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.
WARNING: Felling can result in injury. It should only be performed by a trained person.
• 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.
• Notching Undercut - Make the notch (27) 1/3 of the diameter of the tree, perpendicular to the
direction of the fall (26). 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.
• Felling Back Cut (28) - Make the felling back cut at least 2 inches (50mm) 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 (29). The hinge wood keeps the tree from
twisting and falling in the wrong direction. Do not cut through the hinge.
