Rotating brush and roller brush unit
The brushes in the brush unit
are, depending on the actual version,
driven by two or three electric motors. The brush unit is lowered with the
Brush unit
button. When actuating the accelerator pedal, the brush
motors and the water supply are switched on. The floor is cleaned by the
rotating brushes and the supply of cleaning solution. The brush pressure can
be changed in the multifunction display.
There is an indicator on the brush desk showing the amount of brush wear.
The brushes in the rotating brush unit can be ejected for maintenance pur-
poses by pressing the soft key
Brush decoupler
in the multifunction
display, see section 5.5.3.
2.4.3
Side brush unit
In order to brush up coarse dirt close to walls and beyond the squeegee, a
side brush unit
with two side brushes can be fitted at the front.
2.4.4
Wiper
To the right and left of the brush unit there are two wipers which avoid spray
water at the side in the working position and lead the waste water to the
centre of the vehicle, where it is easier to vacuum up.
The wipers can be raised if necessary. To do this, raise the wiper at the
handle
and hook the locking hook

into the bracket
above it.
