Before starting felling work, ensure
that:
•
there are no unauthorised per-
sons and no animals within the
fall area (A) of the tree;
•
there is an obstacle-free escape
route for all those involved. Peo-
ple withdraw (B) at an 45° angle
opposite the direction of fall;
•
the area around the trunk is free
of obstacles (risk of tripping!);
•
the next workplace is at least
two and a half tree lengths away.
Before felling the tree, check the
direction in which the tree will fall
and ensure that there are neither
objects nor persons or animals
within a distance of 2½ tree
lengths.

3-5 cm
A tree is felled in two stages:
1. Notch the trunk by approx. one
third of its diameter on the side of
the direction of fall.
2. On the opposite side make the
felling cut slightly higher than the
notch (3–5 cm).
Danger! Never saw the tree
trunk all the way through.
The area (C) is used as a "hinge"
and provides a defined direction
of fall. When felling, stand only at
the side of the tree to be felled!
There is a risk of lifethreatening
injuries!
Trunks lying flat on the ground
Cut halfway into the trunk, then turn
around and saw through from the op-
posite side.

We recommend supporting trunks,
which are to be sawn through, on
sawhorses. If this is not possible,
the trunk should be raised and sup-
ported with the aid of the supporting
branches or via support blocks.

that the guide bar does not touch
the ground!
In area A first cut approx. one
third of the trunk diameter from
top to bottom, then complete the
