S After removing the cutout of wood, make
the felling cut on the opposite side of the
notch. This is done by making a cut about

between the felling cut and the notch to
form a hinge. This hinge will help prevent
the tree from falling in the wrong direction.
Hinge holds tree on stump and helps

NOTE
: Before felling cut is complete, use
wedges to open the cut when necessary to

supported. When a tree doesn't fall com-
pletely, set the saw asideandpull downthe
tree with a cable winch, block and tackle,
or tractor.
