CUT. Stand to the right of the
tree and cut downwards at an
angle.The BREAKING STRIP act as
hinges that control the felling
direction of the falling tree.
Next make the BOTTOM CUT
so that it finishes at the end of
the TOP CUT.All control over the felling
direction is lost if the BREA-
KING STRIP is too narrow or
if the directional cut and felling
cut are badly placed.
The directional cut should run
1/4 of the diameter through
the trunk and the angle
between the TOP CUT and
BOTTOM CUT should be 45!.When the felling cut and
directional cut are complete
the tree should start to fall

This line should be perfectly
