First clear the tree base and work area from inter -fering
limbs and brush and clean its lower portion an axe (see
fig. 18).
When felling, maintain a distance of at least 2 1/2 tree
lengths from the nearest person (see fig. 17).
Note:
The noise of your engine may drown any warning call.
Felling instructions:
Then, establish a path of escape and remove all obstacles.
This path should be opposite to the planned direction of
the fall of the tree and at a 45° angle (fig. 19).
An alternate path must also be selected. Place all tools
and equipment a safe distance away from the tree, but
not on the escape path.
Then, determine the placement of the felling notch (fig.
21). The felling notch when properly placed de-termines
the direction in which the tree will fall. It is made perpen-
dicular to the line of fall and should be as close to the
ground as possible.
Cut the felling notch to a depth of about one-fifth to one-
fourth of the trunk diameter (fig. 22). It should be in no case
higher than it is deep. Make the felling notch very care-
fully.
If the tree has large buttress roots, cut into the largest
buttresses vertically first (horizontally next) and re move
(fig. 20).
