12.5 Basic working technique
m Risk of injury!
This section examines the basic working tech-
nique for using the device. The information provid-
ed here does not replace the many years of train-
ing and experience of a specialist. Avoid any work
that you are not adequately qualified for! Careless
use of the device can lead to serious injuries and
even death!
12.6 Sawing technique
12.6.1 Pull sawing (Fig. 20)
With this technique, sawing takes place with the un-
derside of the guide rail from top to bottom.
The saw chain pulls the device forwards and away
from the user. With this action, the front edge of the
device forms a support, which absorbs the forces that
arise on the tree trunk during sawing. With pull sawing,
the user has significantly greater control over the de-
vice and is able to better avoid kickbacks. This sawing
technique should therefore be used if possible.
12.6.2 Push sawing (Fig. 21)
With this technology, sawing takes place with the top
side of the guide rail from bottom to top. The saw chain
pushes the device backwards, towards the user.
m WARNING!
If the guide rail tilts, the device may be jerked towards
the user with great force. If the user does not balance
the backward force of the saw chain with their body
strength, there is a risk that only the tip of the guide
rail will remain in contact with the wood and kick-back
will occur.
Risk of death or serious injuries!
12.7 Felling a tree (Fig. 22, 23)
m Risk of injury!
Sawing and felling work as well as all related work may
only be carried out by specially trained and briefed per-
sons.
Note
Observe the country-specific regulations for felling
work and obtain information from the relevant authority.

• Make sure that no one can be harmed by the falling
branches and trees.
• Only the persons required for the felling work may
be in the work area.
• Keep the work area at the trunk clear and tidy so that
operators have a safe standing area.
• Keep escape routes clear and tidy in order to be able
to leave the work area quickly.
• Do not carry out felling work in stronger wind condi-
tions, bad weather or poor visibility.
• Keep distances to the nearest workplace of at least
2 1/2 tree lengths.
Tree felling takes place in two steps (Fig. 23):
• Saw a felling sink in the trunk of around one third of
its diameter, on the side of the felling direction (1).
• On the opposite side (2) make the felling cut, which
must be slightly higher than the felling sink (approx.
3–5 cm).
m Risk of injury!
Never saw fully through the trunk. The area (C) serves
as a "hinge" and ensures the correct felling direction.
During felling, only stand to the side of the tree you
intend to fell! There is a risk of life-threatening injuries!
12.8 Trunks lying flat on the ground (Fig. 24)
• Cut around halfway through the trunk, then turn it
over and saw through the other side.
m Product damage!
Ensure that the guide rail does not come into contact
with the ground when sawing through a tree trunk!
12.9 Fallen trunks (Fig. 25)
We recommend supporting trunks on a sawhorse
when sawing through them. If this is not possible, the
trunk should be lifted with the aid of supporting boughs
or with support blocks and supported.
• In area A first cut around one third of the trunk di-
ameter from top to bottom, and then make the sub-
sequent cut from bottom to top.
• In area B first cut around one third of the trunk di-
ameter from bottom to top, and then saw through
from the top.
m Risk of injury!
Do not saw trunks that are strained! Splitting wood or
a tilted guide rail can result in serious injuries!
