DANGER!
Risk of injury!
Felling and delimbing work may only
be performed by trained people!
There is a risk of fatal injuries!

With this technique, sawing occurs with the
upper edge of the saw rail from below
upwards. The saw chain thus pushes the
device backwards towards the user. If the
saw rail twists, the device can fly towards the
user with great force.
If the user does not balance out the force of
the saw chain pushing backwards with his or
her bodily force, there is a danger that only
the tip of the saw rail will make contact with
the wood and there will thus be a rebound
( ► Risk of rebound! – p. 14).
Felling a tree
Before beginning the felling work, make sure
that:
• there are no people or animals in the fell-
ing area of the tree.
• there is an obstacle-free escape route for
each participant. A retreat occurs diago-
nally counter to the felling direction.
• the area around the trunk is free of obsta-
cles (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).
Trunks lying flat on the ground
– Cut into the trunk halfway, then turn over
and saw through from the opposite side.
Propped-up trunks
We recommend that you place trunks to be
sawed through on sawhorses. If this is not
possible, the trunk should be lifted with the
help of supporting branches and placed over
trestles.
NOTICE!
Device damage!
Make sure that the saw rail does not
touch the ground while you are saw-
ing through the trunk!
DANGER!
Risk of injury!
When felling, stand only to the side of
the tree to be felled! There is a risk
of fatal injuries!
DANGER!
Risk of injury!
Never saw the tree trunk completely
through. The area serves as a "hinge"
and ensures a defined felling direc-
tion.
