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
determines the direction in which the tree will fall. It is
made perpendicular 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
carefully.
If the tree has large buttress roots, cut into the largest
buttresses vertically first (horizontally next) and re move
(fig. 20).
