Operation
The development of excessive foam im-
pairs the vehicle's function. It indicates
overdosage of the cleaning agent; com-
ponents of the cleaning agent which are
fed back to the waste water cause
foaming. Information on dosage is pro-
vided on the cleaning agent container.
Use the manufacturer's information as
an initial guideline. Practical experience
will ensure that you quickly find out
which is the right cleaning agent and
the optimum dosage to suit your needs.
The solution feed to the brushes is au-
tomatically opened when the scrubbing
program is activated. If necessary, the
feed can be stopped manually by
means of the ball cock.
Operating times with one tankful:
• at 2 l/min. approx. 155 minutes
• at 4 l/min. approx. 77 minutes
• at 7 l/min. approx. 44 minutes
The recovery tank is located behind the
driver's seat, on the left-hand side
(when facing the front). The recovery
tank is a tank partitioned by a mem-
brane panel and has a volume of ap-
prox. 310 liters. The waste water is fed
to the recovery tank via the squeegee
by means of a vacuum. A float switch at
the top of the recovery tank switches
the suction turbine off automatically as
soon as the maximum tank fill level is
reached. In this case, the control lamp
(Fig. 17/2) on the left operating panel
lights up. An acoustic signal is also is-
sued. A vacuuming tool (refer to Sec-
tion 4), which can be connected to the
vehicle, is optionally available with
which to clean and vacuum up water
from areas difficult to access.
The traction drive is provided by a drive
motor on the steerable front wheel. The
driving speed can be continuously reg-
ulated via the accelerator by means of
the electronic drive control (pulse con-
tact control). The axle gear is a gear
train running in an oil bath and is low-
maintenance: no gear oil change is nec-
essary.
In the case of faults involving
the traction drive, stop the ve-
hicle immediately and remove
the key from the key switch!
The scrubber drier is equipped with a
service brake and a parking brake.
The service brake relates to a drum
brake which acts hydraulically on the
rear wheels. It is actuated by a foot ped-
al. The parking brake is actuated me-
chanically via brake cables. It is applied
by means of the foot pedal to the left of
the steering column and released using
the safety catch in the steering column.
