Operation
Forward and reverse movement with the right foot

The pedal must not be operated with the tips of
your shoes only!
To be able to react quickly in dangerous situations,
the shoe must be positioned completely on the
operating pedal.

The brake is applied by slowly moving the operating pedal to
the 0 position.

A strong braking is achieved by counteracting the operating
pedal.

Tilting the operating pedal forwards: lowering the jib.
