Danger
Danger of accident. The immobilizing brake
must always be checked first on an even
surface before starting the machine.
Î Take the seating position.
Î Release emergency-stop button by
turning.
Î Set main switch to “1”.
Î Select a direction of travel.
Î Gently depress drive pedal.
Î The brake must get released and you
must be able to hear it (the control lamp
for immobilizing brake on the console
switches off). The machine must roll
slightly on a plane surface. When the
pedal is released, the brake falls in in an
audible manner. Switch off the machine
and call the aftersales service if the
above-mentioned events do not occur.

Danger
Danger of accident. If the machine does not
brake, then proceed as follows:
Î If the device does not come to a halt on
a ramp with a gradient of 2% when you
release the drive pedal, then the emer-
gency-stop button may be pressed for
safety reasons only if the mechanical
functioning of the immobilizing brake
has been checked properly before com-
missioning the device.
Î Switch off the machine only after it
comes to a complete halt (on an even
surface) and call up the aftersales serv-
ice!
Î Further, follow all warning instructions
for braking.

Danger
Danger of tipping if gradient is too high.
Î The gradient in the direction of travel
should not exceed 10%.
Danger of tipping when driving round bends
at high speed.
Danger of slipping on wet floors.
Î Drive slowly when cornering.
Danger of tipping on unstable ground.
Î Only use the machine on sound surfac-
es.
Danger of tipping with excessive sideways
tilt.
Î The gradient perpendicular to the direc-
tion of travel should not exceed 10%.
Î Release emergency-stop button by
turning.
Î Sit on the seat and set main switch to
"1".
Î Set the drive direction using the drive di-
rection button at the operator console.
Î Determine the driving speed by press-
ing the drive pedal.
Î Stop the machine: Release the drive
pedal.
Note
The drive direction can also be changed
during the drive. Thus, very blunt edges can
be polished by moving forward and back-
ward a few times.
When switching on the display, the follow-
ing messages will appear in sequence:
– „ < SELFTEST >“: The control conducts
a self-test.
– „Water E-----F“ (model Adv): Water level
in the fresh water tank (lasts for 6 sec-
onds).
„OpHrs xx“ (Classic model):
Operating hours (lasts for 6 seconds)
– "Battery: E-----F“: Charging status of
battery.
In case of overloading, the drive motor au-
tomatically switches off after a certain peri-
od. A fault message is displayed on the
console. The concerned unit gets switched
off if the controls get overheated.
Î Allow machine to cool down at least for
15 minutes.
Î Turn the main switch to "0" and turn it
back to "1".

Warning
Risk of damage. Only use the recommend-
ed detergents. With respect to different de-
tergents the operator bears the increased
risk regarding the operational safety and
danger of accident. Only use detergents
that are free from solvents, hydrochloric
acid and hydrofluoric acid.
Note
Do not use highly foaming detergents.
Recommended detergents:
Î Open the cover of the fresh water reser-
voir.
Î Fill fresh water (max. 60 °C) until 15 mm
below the upper edge of the tank.
Î Pour in detergent.
Note
If detergent is added to the cleaning deter-
gent tank first, followed by water, there
could be a lot of foam.
Î Close the cover of the fresh water reser-
voir.
Note
Fill up the fresh water tank completely be-
fore starting up the machine to ventilate the
water supply system.
Î Connect the water hose to the connec-
tion neck on the filling system.
Î Open the water supply.
Once the maximum fill level is reached,
the built-in floater valve will stop the wa-
ter inflow.
Î
Shut off water supply.
Î
Remove the water hose.
Detergent is added to the fresh water on the
way to the cleaning head with the help of a
dosaging device.
Î Place the detergent bottle into the de-
vice.
Î Close the bottle lid.
Î Insert the suction hose of the dosaging
equipment into the bottle.
Note
The metering device can be used to add 3%
of detergent at maximum. In case of a high-
er dose the detergent must be poured into
the fresh water tank.
몇
Warning
Danger of plug-up by dried detergent when
the detergent is added to a fresh water tank
made by Dose. The flow meter of the dos-
ing equipment can stick on account of dry-
ing detergent and hamper the functioning of
the dosing equipment. Always rinse at the
end the fresh water tank and the appliance
with clear water. To rinse, open the regulat-
ing knob fully, set the detergent metering
