Operation
3.1.2
Scrubbing
The figures in this operating
manual generally illustrate the
rotary brush head. The vehicle
can also be equipped with a
circular brush head.
The vehicle implements a brush head
(Fig. 3/1) with two rotating brushes for
the scrubbing operation. You must de-
cide whether to use a brush head with
circular brushes or roller brushes.
When scrubbing mode is activated, the
brush head is automatically lowered by
an electric servomotor on starting to
drive, the brushes start to rotate and so-
lution supply to the nozzles is automati-
cally activated. When the vehicle is
stopped, the brush head is automatical-
ly raised and the brushes and solution
supply are switched off.
The solution tank (Fig. 3/2) provides the
solution necessary for the scrubbing
operation.
3.1.3
Vacuuming
After scrubbing, the resulting dirty water
on the floor is normally vacuumed up.
To do this, the adjustable squeegee
(Fig. 3/3) draws the waste water from
the floor by means of a sealing strip.
When vacuuming mode is activated,
the squeegee is automatically lowered
by an electric servomotor on starting to
drive and the suction turbine is switched
on. When driving in reverse, the squee-
gee remains in its raised position.
The dirty water drawn up by the squee-
gee is fed into the recovery tank (Fig. 3/
4).
3.1.4 Driving
The vehicle is driven by an electric mo-
tor on the front wheel (Fig. 3/5). The
electronic control unit converts the posi-
tion of the throttle and throttle to driving
speed, driving direction and decelera-
tion.
The vehicle is provided with the electri-
cal power necessary for operation from
batteries (Fig. 3/6). The batteries must
be recharged regularly by means of an
external charger.
3.1.5 Options
• Scrubbing-vacuuming tool for spray-
ing, scrubbing and vacuuming. It
serves to clean areas which the vehi-
cle cannot access.
To connect the scrubbing-vacuuming
tool, disconnect the top end of the suc-
tion hose from the vehicle nozzles and
connect the hose from the scrubbing-
vacuuming tool. The solution hose con-
tinues to be connected to the coupling
beside the nozzles. The scrubbing-vac-
uuming tool is ready for operation after
pressing the relevant switch below the
steering wheel.
A brush and suction adapter, which can
be screwed out and changed, are
mounted at the bottom end of the ex-
tendible telescopic rod. When the grip
switch is pressed, a jet of the solution is
sprayed out of the nozzle above the
brush.
