Hydrostatic drives are deemed very safe. The following measure additionally
increases this safety, if there should be any operating faults of the drive.
If, when releasing the driving pedal, the machine should neither reduce driving speed
nor stand still, then a safety circuit is activated by engaging the parking brake (1).

This safety circuit bypasses the standard control behaviour of the hydraulic system
and opens a safety valve that quickly shuts off the traction drive.
If, in the extremely improbable case of failure of all safety devices, the machine still
does not stop, then shut off the diesel engine at the ignition key as quickly as possible.
(see page 86) (see page 144)
DANGER
Danger of severe rear-end collisions with injuries hazardous to life or even
deadly when engaging the parking brake or shutting off the diesel engine, while
the machine is driving.
– Therefore, take this EMERGENCY-STOP measure only in extreme emergencies
and try to warn following traffic by pressing the foot brake pedal several times and
switching on the hazard warning system.
If the vehicle should move only very slowly after switching to the operating mode "Rab-
bit", then the R-Touch displays the respective icon: e.g. "Put truck conveyor in trans-
port position" . Make sure before start driving, that the machine is completely in
transport position.
If the supply pressure in hydrostatic drive is too low (15 bar) the orange warning icon
appears: Please stop and call customer service!
