Operation
3.1.5 Waster water tank
(Fig. 14/1)
The waste tank is located on the left be-
hind the driver's seat (looking towards
the front). The waste water tank is a
tank partitioned by a membrane panel
and has a volume of approx. 296 liters.
The waste water is fed to the waste wa-
ter tank via the squeegee by means of
a vacuum. A float switch at the top of
the waste water tank switches the suc-
tion turbine off automatically as soon as
the maximum tank fill level is reached.
In this case, the control lamp (Fig. 19/2)
on the left operating panel lights up. An
acoustic signal is also issued. A vacu-
uming tool (refer to Section 4), which
can be connected to the vehicle, is op-
tionally available with which to clean
and vacuum up water from areas diffi-
cult to access.
3.1.6 Traction drive
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
necessary.
In the case of faults involving
the traction drive, stop the
vehicle immediately and
remove the key from the key
switch!
3.1.7
Brakes
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.
