Felling instructions:
First clear the tree base and work area from interfering
limbs and brush and clean its lower portion with an axe
(see g. 18).
When felling, maintain a distance of at least 2 1/2 tree
lengths from the nearest person (see g. 17).
Note:
The noise of your engine may drown any warning
call.

Then, establish a path of escape and remove all obsta-
cles. This path should be opposite to the planned
direction of the fall of the tree and at a 45° angle (g.
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
(g. 21). The felling notch when properly placed de-
termines 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-fth to one-fourth of the trunk
diameter (g. 22). It should be in no case higher than it
is deep. Make the felling notch very carefully.
