person.
When felling in the vicinity of roads,
railways and power lines, etc., take extra
precautions. Inform the police, utility

Escape Path
1
A
First clear the tree base and work area
from interfering limbs and brush and
clean its lower portion with an ax.
Then, establish two paths of escape (B)
and remove all obstacles. These paths
should be generally opposite to the
planned direction of the fall of the tree
(A) and about at a 45° angle. Place all
tools and equipment a safe distance
away from the tree, but not on the
escape paths.
Buttress Roots
45°
If the tree has large buttress roots, cut
into the largest buttress vertically first
45°
(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.
