connected to the step control and the battery voltage must also be connec-
ted.

F Driving the step control in an out by briefly tipping pressing the button
at the entrance; the motor is switched off when the step control re-
aches the stop.

frozen.
F The control can be accessed via an (optional) second switch at the
driver’s seat.
