Operation
Driving
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 (32).
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 down the diesel engine with the STOP key (18) or ignition key
as quickly as possible. (See Page 94) (See Page 171)
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, only use this EMERGENCY STOP function in an extreme emergency
and try to warn following traffic by pressing the foot brake pedal several times and
switching on the hazard warning lights.
If the vehicle moves very slowly after switching to the operating mode "Rabbit", the
respective icon appears on the R-Touch: e.g. "Please move truck conveyor to transport
position" . Before starting the machine, make sure that it is entirely in the transport
position.
If the supply pressure in hydrostatic drive is too low, the orange warning icon appears:
Please stop and call customer service!
