When the fall direction of the tree has been determined, the felling
notch must be cut. The felling notch is made in the fall direction of
the tree.
Proceed as follows to make the felling notch:

If the top and bottom cuts of the felling notch do not meet exactly
and/or the top and bottom cuts of the felling notch are too deep, the
tree can break off prematurely, leading to severe injuries.
