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. Remove dirt, stones, loose bark, nails, staples,
and wire from the tree where felling cuts are to be made.
7.3.1 Notching undercut (Fig.13)
Make the notch 1/3 the diameter of the tree, perpendicular to the direction of 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.
7.3.2 Felling back cut (Fig.14)
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 desired direc-
tion.
Do not cut through the hinge.
