Buttons con-
trolling the
solution supply
(Fig. 16/11) The
solution con-
sumption 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 7.5 l/min (all
seven lamps are on). The minimum
quantity is 1.3 l/min (only the left lamp is
on). The last solution quantity selected
is always used. When the scrubbing
program is switched on for the first time,
a solution quantity of approx. 3.5 l/min
is automatically set.

quantity
(Fig. 16/12) The button serves
to reduce the solution quantity
supplied to the brushes. The solution
quantity can be reduced in seven stag-
es (see above). The selected stage re-
mains programmed (last station
memory) even if the machine is
switched off temporarily.
Button to switch the solu-
tion supply on and off
(Fig. 16/13) This button serves
to switch the solution feed on
and off when the brush head is lowered.
The solution quantity previously set re-
mains unaltered (last station memory).
Button to increase solution
quantity
(Fig. 16/14) This button serves
to increase the solution quantity
supplied to the brushes. The solution
quantity can be increased in seven
stages (see above). The selected stage

turbine, brush rotation, solution feed
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 Hako
button. When the Hako button has been
pressed, the green control lamp lights
up.
