Operation
Button for side scrubbing
unit
(Fig. 17/7)
This button is used
to activate the side scrubbing
unit. After pressing the button,
the two brushes start or stop rotating
and the brush is lowered or raised ac-
cordingly. When the side scrubbing unit
is activated, the green control lamp
lights up.
The side scrubbing unit is an optional
accessory. If it is not installed, the but-
ton has no function.
The side scrubbing unit can
only be switched on when the
circular brushes are also
switched on.
Button for brush pressure
(Fig. 17/8)
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. 47 kg. If the func-
tion is active, the green control lamp
lights up.
Working with an increased
brush pressure also means in-
creased brush wear. There-
fore, only press this button
when necessary.
Button for brush drive
(Fig. 17/9)
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.
