•
Ensure no supply lines are affected or ma-
terial damage is caused when felling trees.
If a tree comes into contact with a supply
line, the supplier of the line must be notified
immediately.
•
Take into account the natural angle of the
tree, the position of larger branches and
the direction of the wind prior to felling to
be able to assess the direction the tree will
fall in.
•
Remove dirt, stones, loose bark, nails,
clamps and wires from the tree.

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 life
threatening injuries!
The tree must begin to fall upon coming close
to the felling cut at the strut. If it becomes ap-
parent that the tree might not fall in the de-
sired direction or it is leaning back, thus jam-
ming the saw chain, stop cutting and position
wooden or plastic wedges at the correspond-
ing positions to expose the cut or make the
tree fall in the desired direction.
Once the tree starts falling, remove the chain
saw from the cut, put it down and leave the
hazardous area via the planned escape route.
Look out for falling branches and do not trip.

Cut halfway into the trunk, then turn around
and saw through from the opposite side.
Warning! When sawing through the
trunk, ensure that the guide bar
does not touch the ground!
Supported trunks
•
In area A first cut approx. one third of the
trunk diameter from top to bottom, then
complete the cut from bottom to top.
•
In area B first cut approx. one third of the
trunk diameter from bottom to top, then cut
through from the top.

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