Operating modes

The device can either be operated via remote control (Re-
mote Control = RC mode) or while riding on the device (Man-
ual Control = MC mode).
You can switch between operating modes at any time. How-
ever, it requires a great degree of knowledge to avoid faults
and risks. Please read the corresponding chapter carefully.
First, familiarize yourself with the device in the MC mode and
practice the procedures on a spacious, obstacle-free and flat
area.

Ride-on mode (MC):

We recommend working in the ride-on mode,
– to efficiently mow big, flat areas.
– to precisely navigate around sensitive obsta-
cles.
– to easily detect obstacles and foreign objects
and thus be safe from ejected parts.
– to easily detect obstacles and foreign objects
and thus avoid damage of the device.

Remove control mode (RC)

We recommend working in the remote control mode,
– when you want to protect yourself against
noise, physical strain, vibrations, exhaust
fumes, dust, sun, or rain.
– in inaccessible places such as in undergrowth,
low branches or thorns.
– on slopes.
– to have a better overview of the danger area
and thus avoid accidents.
– at the water's edge or in the proximity of
edges with a risk of falling.
– on soft, sensitive grounds.
– to keep insects or pollen away.

Safety functions

To ensure safe operation at all times, the device is equipped
with safety functions. To make the engine and the blade run,
depending on the operating mode, certain requirements need
to be fulfilled. These requirements are described in the corre-
sponding chapters.

Checking the slope

Warning
Driving on slopes is dangerous. There is a tilting and slip-
ping hazard.
► Observe the safety instructions regarding driving on
slopes and the danger area.
1. Operate the device in Remote (RC) mode on slpes.
2. On level ground, drive slowly with disengaged blade
crosswise onto the slope.
3. Stop the device.
4. Read the cross slope at the inclinometer at the rear of the
device.
5. If the slope is in the admissible range, move to a steeper
part and repeat the cross slope test.
6. Do not mow on slopes greater than 33°. Move on to flatter
ground.
Öldruckschalter
The oil pressure switch signals via the oil control light on the
Remote Control Transmitter when engine damage due to low
oil pressure is about to occur. This may occur when:
– Oil level is too low.
– The device is in too steep a sloping position.
How steep the gradient may be for the oil pressure switch to
signal depends on the engine type, direction of inclination,
and the oil level.

Oil pressure drop

When the device detects an oil pressure drop, the oil control
light on the Remote Control Transmitter lights up.
1. Move the device to flat terrain.
2. Oil control lamp on the Remote Control Transmitter is
off:
ð The device was at excessive incline.
ð The oil pressure is restored and you can continue to
work.
3. Oil control lamp on the Remote Control Transmitter
lights up.
ð The oil pressure of your device is still too low.
If the oil pressure of your device is still too low:
1. Switch off the engine.
2. Check the oil level.
3. If the oil control light lights up even though the oil level is
sufficient, contact an authorized service center.
Beware: If you drive for several minutes without oil pressure,
engine damage will result.
