6.10.3 Parking brake
Operating of the parking brake is performed using the toggle switch on the console.
The parking brake affects front wheels. Even when the ignition is switched off and the
pneumatic system is pressureless, the parking brake is automatically engaged and
in effect. For safety reasons, the parking brake can only be released when sufficient
pressure is present in the pneumatic system.
When the parking brake is engaged, the icon appears on the R-Touch .
As long as the parking brake is engaged, pressure on the gas pedal is without effect.
In an emergency, the spring-loaded actuator of the brakes may be manually mechan-
ically released. For instructions see chapter 8 "Malfunction and Remedies". (see
page 426)
If the parking brake is not released sufficiently (e.g. too low release pressure), then the
following warning icon is displayed on the R-Touch .
6.10.4 Automatic parking brake (only in the operating mode "Rabbit")
When the machine has been at a standstill for several seconds (gas pedal released),
the parking brake is engaged automatically. When the automatic parking brake is
active, then the following icon is displayed on the R-Touch:
= Automatic parking brake active.
This avoids, in a slanted landscape, for safety reasons, inadvertent rolling away of
the machine. When the gas pedal is pressed again, the automatic parking brake is
released.
