First clear the tree base and work area from inter fering
limbs and brush and clean its lower portion 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.
Felling instructions:
Plan your work, ensuring an obstacle-free work area
and, in the case of felling, have at least one escape
path from the falling tree prepared in advance.
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
(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
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.

carefully.
