3. An escape path should be planned and cleared as necessary before cuts are
started. The escape path should extend back and diagonally to the rear of
the expected line of fall (Fig. 33).

4. 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.
5. Remove dirt, stones, loose bark, nails, staples and wire from the tree.
8. Notching undercut
Make the notch (Fig. 34, B) 1/3 the diameter of the tree, perpendicular to the
direction of falls (Fig. 34). Make the lower horizontal notching cut first. This will
help to avoid pinching either the saw chain or the guide bar when the second
notch is being made.

9. Felling back cut
1. Make the felling back cut (Fig. 34, A) at least 50 mm higher than the
horizontal notching cut (Fig. 34). 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 (Fig. 34, C) wood keeps the tree from twisting and
falling in the wrong direction. Do not cut through the hinge.
2. As the felling gets close to the hinge, the tree should begin to fall. If there is
any chance that the tree may not fall in desired direction or it may rock back
and bind the saw chain, stop cutting before the felling back cut is complete
