Operation
Button for brush pressure
(Fig. 19/8)
This button is used
to increase the brush pres-
sure. This may be necessary
when the area to be cleaned is
extremely dirty. The pressing force can
be increased to max. 93 kg. If the func-
tion is active, the green control lamp
lights up.
Working with an increased
brush pressure also means
increased brush wear.
Therefore, only press this
button when necessary.
Button for the brush drive
(Fig. 19/9)
This button serves
to switch the brushes and solu-
tion feed on and off with simul-
taneous, respective lowering
and raising of the brush head. If the
function is active, the green control
lamp lights up.
Button for squeegee and
suction turbine
(Fig. 19/10)
This button serves
to switch the suction turbine on
and off with simultaneous low-
ering and raising of the squeegee. If the
function is active, the green control
lamp lights up.
This button must also be
pressed when working with
optional tools connected to a
suction hose. Operating
personnel must not be seated
on the driver's seat in this case
(seat contact is bypassed).
Only the suction turbine is
activated at this point, the
squeegee remains raised.
