injuries!
Before beginning the felling work, make sure that:
• there are no people or animals in the felling area of
the tree.
• there is an obstacle-free escape route for each par-
ticipant. A retreat occurs diagonally counter to the
felling direction.
• the area around the trunk is free of obstacles (risk of
stumbling!).
• the next workplace is at least two and a half tree lengths away. Before felling, the felling direction
of the tree must be checked and it must be ensured that there are no objects, people or animals in
a distance of 2 1/2 tree lengths.
The felling of a tree occurs in two steps:
1. Notch the trunk by approximately one-third of its diameter on the felling direc-
tion side.
2. On the other side, make the felling cut, which must be somewhat higher than
the felling notch (approx. 3–5 cm).

Never saw the tree trunk completely through. The area serves as a "hinge" and ensures a
