Machine Home Position - HAKO Scrubmaster B 120 R Service Booklet

2.2.3 Machine home position

After turning on the machine, all components are set to "home position" if the seat
contact switch is actuated (closed).
The lifting elements will be raised if they have not already been switched off via the
micro-switch for the upper end position integrated in the lifting element (squeegee) or
the upper end position is detected by the control unit via the integrated potentiometer.
The motors are switched off and the LED indicators in the control panel for the
cleaning components go out.
The lifting element for the brush head features integrated position detection via a
potentiometer.
When removed, the spindle of the lifting element may not be twisted as otherwise the
positioning of the lifting element is misaligned.
