Operation
Button for squeegee and
suction turbine
(Fig. 19/10) This button
serves to switch the suction
turbine on and off with simul-
taneous lowering and raising
of the squeegee. If the function is ac-
tive, the green control lamp lights up.
This button must also be
pressed when working with op-
tional tools connected to a suc-
tion hose. Operating personnel
must not be seated on the driv-
er's seat in this case (seat con-
tact is bypassed). Only the
suction turbine is activated at
this point, the squeegee re-
mains raised.
Button for simultaneous
activation of the scrubbing
unit and vacuuming func-
tion
(Fig. 19/11) After pressing
the button, the most important basic
functions for standard cleaning are au-
tomatically activated/deactivated in the
correct sequence of use: suction tur-
bine, brush rotation, fresh water supply
and lowering or raising the brushes and
squeegee. When the vehicle is ready
for use in accordance with require-
ments, it can be set into operation sim-
ply and quickly by pressing the button.
When the button has been pressed, the
green control lamp lights up.
Buttons con-
trolling the
fresh water
supply
(Fig. 19/12) The
fresh water consumption used during
cleaning can be regulated in seven
stages. Accordingly, there are seven
green control lamps on the keypad.
Each lamp relates to one stage. The
maximum quantity which can be used
for cleaning is 2.0 gal/min (all seven
lamps are on). The minimum quantity is
0.3 gal/min (only the left lamp is on).
The last fresh water quantity selected is
always used. When the scrubbing pro-
gram is switched on for the first time, a
fresh water quantity of approx.
0.9 gal/min is automatically set.
