2.2 Brief description

Machine control takes place with the following electronics:
• Central electronics (A1)
• Control and display panel (A2)
• Drive control (A4)
• Chemical dosing (A101)
The control electronics (A1) assumes all control and monitoring tasks in the machine
except for the drive functions.
In addition to the group messages of the drive control on the machine's display, these
are shown as detailed flash codes using a flash LED. (see Chapter 9).
It is possible to toggle back and forth between the tip switches for scrubbing,
vacuuming and the green Hakomatic button for combined cleaning, thus ensuring that
the selected function is activated. When pressing tip switch "boost", the brush
pressure is increased and the water quantity set to max. as long as the tip switch is
pressed.
Tool operation can only be switched on if the parking brake is applied and the seat
contact switch is open.
