power supply in battery mode. The high‐voltage power supply is
required for the milling drum drive and for charging the batteries.
Danger due to automatically moving machine.
The operating and maintenance personnel responsible for
the machine must ensure that no one can enter the ma
chine's danger zone during operation or maintenance work.
If the milling rotor is in operation, the running machine can
only be stopped using the Milling joystick [29] or an
EMERGENCY STOP button [27/37] .
The machine has been put into operation
(!Chapter 5.2, page 13).
1. Press the two Support pushbuttons [34/39] in the direc
tion.
Both support wheels [5] are moved down to the stop and
the milling rotor is lifted off the floor.
For manoeuvring and driving short distances, the milling
drive that is raised off the floor can remain switched on.
2. Use the Driving joystick [32] to control the direction of tra
vel.
The display is as illustrated.
If the Milling joystick [29] is moved in the direction or an
EMERGENCY STOP button is pressed, the machine
stops.
In automatic mode, both support wheels [5] are moved
down to the stop. The milling rotor stops and is lifted off the
floor.
The travel speed is permanently set to the maximum.
The travel speed in m/min is shown on the display.
GG" The manufacturer recommends performing a test drive.

Risk of injury from rotating milling rotor.
Do not reach or step near the milling rotor.
Never allow unauthorised persons to approach the ma
chine.
Switching on milling mode
The machine and the remote control have been put into
operation (!Chapter 5.2, page 13).
The machine is connected to a CEE socket (32A) connec
ted in accordance with the regulations.
1. Press the two Support pushbuttons [34/39] in the direction
Both support wheels [5] are moved down to the stop and
the milling rotor is lifted off the floor.
2. Move the Milling joystick [29] in the direction.
The display is as illustrated.
The milling drive is switched on and the milling rotor rota
tes.
Setting the milling speed
The milling speed can be changed at any time using the Milling
speed pushbutton [35].
Switch off the milling drive
—Move the Milling joystick [29] in the direction.
The machine stops.
Both support wheels [5] are moved down to the stop. The
milling rotor stops and is lifted off the floor.

5.5 Setting the milling depth and milling angle
The Support pushbuttons [34/39] are used to change the length
of the supports and thus to move the milling rotor up or down at
the corresponding side. That determines the milling depth and
the milling angle.
The machine has been put into operation
(!Chapter 5.2, page 13).
The milling rotor is raised.
The milling motor has been switched on
(!Chapter 5.4, page 17).
3. Loosen both clamping wheels [13] and use both cranks [11]
to turn the stops [12] up anticlockwise ↺(!Figure A).
4. Press the two Support pushbuttons [34/39] alternately in
the direction.
GG" Do not fail to observe the inclination indicator [45].
The inclination indicator [45] shows the angle of the milling
rotor (on flat ground normally 0/0).
5. Slowly lower the milling rotor until it only just touches the
floor (!Figure B).
6. If the cut‐out is to be at an angle (e.g. 2.5 ) to the floor:
—Press the Support pushbutton on the side that is to
have the cut‐out (e.g. [34]) in the direction until the
inclination indicator [45] shows the sum of the floor
inclination (normally 0°) and the desired cut‐out angle
(e.g. 2.5°) (!Figure).
GG" It is essential to ensure that the inclination indicator [45]
always shows the required value from now on.

Deviations can be corrected by different settings of the
cranks [11].
7. Use both cranks to turn the stops [12] down clockwise ↻
up to the stop (!Figure C).
The set milling depth is now 0 mm.
8. Loosen the 2 knurled nuts [46] and move the milling depth
scale [47] until the pointer [48] indicates 0(zero) and tigh
ten the knurled nuts.
9. Turn both cranks anticlockwise ↺ until the required milling
depth is set (!Figure D).
One turn of the crank corresponds to a lowering distance of
2 mm. Example:
Example: If a milling depth of 8 mm is required, both
cranks must be turned 4 turns anticlockwise ↺.
GG" The maximum milling depth: 10 mm (green scale range)
Die maximum work depth for separating: 30 mm.
Do not fail to observe the inclination indicator [45].
Risk of damage due to excessive milling depth.
Milling with a greater milling depth than specified here
will result in significantly increased wear on the milling
rotor and the machine.
This must be avoided.
10. Tighten both clamping wheels [13].
If the cranks [11] were turned up to the stop anticlockwise
↺, the milling depth can also be set using the Support pu
shbutton [34/39] (inaccurate method).
The milling depth and the milling angle have been set.
5.6 Floor milling
Risk of injury from rotating milling rotor.
Do not reach or step near the milling rotor.
Never allow unauthorised persons to approach the machine.
Risk of injury from automatic movements.
The operating personnel responsible for the machine must
ensure that no‐one can enter the machine's danger zone
during operation.
Risk of injury from loud noises.
Use hearing protection.
Risk of injury
from accumulation of dust during milling work.
The machine may only be operated with water spraying
and/or a dust extraction system with appropriate filtration.
Use respiratory protection.
Risk of injury.
All persons in the working area of the machine must wear
appropriate tight‐fitting work clothing and safety footwear.

Risk of damage.
When milling on downhill slopes (from top to bottom), the
milling results in an additional pushing effect.
When milling on uphill slopes, always mill "uphill"
(from bottom to top) (!Figure).
The machine has been put into operation
(!Chapter 5.2, page 13).
The milling motor has been switched on
(!Chapter 5.4, page 5.4).
The milling depth and the milling angle have been set
(!Chapter 5.5, page 18).
1. If necessary, connect an external dust extraction unit to the
suction nozzle [20].
2. Check that the milling rotor is working correctly:
The milling rotor rotates correctly and the drum seal is
undamaged.
There are no unusual noises.
Troubleshooting !Chapter 7, page 30.
3. Press the two Support pushbuttons (34/39) in the direc
tion.
The pointer [48] indicates the milling depth on the scale.
The display is as illustrated.
The display shows the milling speed in m/min and the total
operating time in hours (hrs) or the state of charge of the
batteries (%).
4. Set the milling speed using the Milling speed pushbutton
[35].
5. either:
Depending on the desired surface and milling depth, mill
with a milling speed of 1 m/Min ... 2 m/Min.
or:
Depending on the desired cutting depth, cut with a cutting
speed of 0.25 m/Min ... 0.6 m/Min.
If the milling depth and/or the travel feed is excessive, the
machine will not run smoothly. The milling pattern becomes
wavy and uneven.
The milled material lies on the milled surface and can be remo
ved there. Then, the milling depth and the milling quality can be
checked.
6. At the end of the milled path:
—Push the Milling joystick [29] in the direction.
The machine stops.
Both support wheels [5] are moved down to the stop. The
milling rotor stops and is lifted off the floor.
Risk of injury from milling rotor still rotating after the ma
chine is switched off.
The milling rotor may continue to turn for several seconds
after switching it off (follow‐up movement).
—Check the milling depth and the milling quality and make
corrections, if necessary (!Chapter 5.5, page 18).
