Buttress roots
If the tree has large buttress roots, cut
into the largest buttress vertically first
(horizontally next) and remove the
resulting piece.
Gunning sight
When making the felling notch, use the
gunning sight on the shroud and housing
to check the desired direction of fall:
Position the saw so that the gunning
sight points exactly in the direction you
want the tree to fall.
