service brake [512]
The driving speed is proportional to the magnitude of the lever
displacement. However, it is dependent on the pre-selected velocity
range [314].
If the machine is equipped with a back-up alarm, an acoustic signal
sounds when travelling reverse.

502 0 position lock / parking brake
For latching, the right drive lever must be pushed in central position
into the 0-position lock. Two functions are assigned to this position. For
unlatching, press the drive lever in the direction of the driver's seat.
The 0-position lock is a safety device. It avoids unintended movement of
the machine.

If the drive lever is latched in the 0-position lock, the parking brake is

Parking brake is released after the drive lever unlatches. The
pilot light goes out.
