6.5 Correct operation
n
Bring the drum cutter into a raised position.
n
Switch on the drum cutter and start up.
n
Slowly lower the rotating cutter drum onto the cutting
material.
n
Slowly apply slight pressure to the cutter drum and
ensure it does not block.
WARNING Risk of injury due to loss of stability
Lateral cutting movements can endanger the stability
of the carrier and result in strong vibration being ex-
erted on the machine and the operator, which can in
turn lead to severe injuries and considerable damage
to property.
u
Do not expose the carrier to the effects of strong
forces.
u Ensure that the carrier maintains constant contact
with the ground during cutting work.
u Always execute cutting movements slowly.
u
Never switch the drum cutter on or off when in
contact with the cutting material.
n
Execute cutting movements towards the carrier vehi-
cle or in both directions.
n
Execute the cutting movements either in a horizontal
or vertical direction. With lateral cutting movements,
always ensure that no strong forces are exerted on
the carrier.
n
Always introduce the rotating cutter drum to the cut-
ting material slowly in order to avoid stalling.
n
Always apply slight pressure to the drum cutter when
cutting. Always ensure that the cutter drum does not
come to a standstill.
n
With lateral cutting movements with the boom, al-
ways ensure that no strong forces are applied to the
carrier.
n
Never switch the drum cutter on or off when in con-
tact with the cutting material.
n
Check the hydraulic oil temperature regularly when
working in continuous operation. This must not ex-
ceed 80 °C (176 °F).
When cutting abrasive materials (e.g. concrete, sand-
stone) and using water spray for dust suppression, it is
necessary to reckon with considerably greater wear
rates. The same applies when cutting under water.
6.5.1 Operating the drilling auger
Working angle
n
Always position the drilling auger at a right angle on
the ground.
90°
NOTICE Damage due to bending force
When working with the drilling auger, strong bending
forces act on the hexagonal receiver and the drilling
auger if drilling is not carried out exactly vertically.
u When drilling, make sure that the drilling auger is al-
ways guided vertically and not bent.
90°

n
Regularly raise the drilling auger out of the ground to
clear it from material. This will help maintain drilling
effectiveness.
n
When the drilling auger is out of the ground check the
condition of the drilling head. At least every 30 min-
utes.
