DANGER
Risk of accident. Prior to every operation,
the parking brake must be checked for
proper function on a level ground.
 Turn on the appliance.
 Set the travel direction switch to "for-
ward".
 Set programme selector switch to trans-
port run.
 Stand on platform and operate safety
switch.
 Gently depress drive pedal.
 The brake must unlock audibly. The
machine must roll easily on a plane sur-
face. When the pedal is released, the
brake locks audibly. Switch off the ma-
chine and call the aftersales service if
the above-mentioned events do not oc-
cur.
 DANGER
Risk of accident. If the device does no long-
er show any braking effect, proceed as fol-
lows:
 If the device does not come to a halt on
a ramp with a gradient of 2% when you
release the accelerator pedal, for safety
reasons, the Emergency-stop button
may be pressed only if the mechanical
functioning of the parking brake has
been checked properly before every
startup of the device.
 Switch off the machine only after it
comes to a complete halt (on an even
surface) and call up the aftersales ser-
vice!
 Further, follow all warning instructions
for braking.
 DANGER
Danger of tipping if gradient is too high.
 The gradient in the direction of travel
should not exceed 10%.
Drive only lengthwise on uphill and
downhill gradients, do not turn.
Danger of tipping when driving round
bends at high speed.
Danger of slipping on wet floors.
 Drive slowly when cornering.
Danger of tipping on unstable ground.
 Only use the machine on sound surfac-
es.
Danger of tipping with excessive sideways
tilt.
 Plug in the Intelligent Key.
 Release emergency-stop button by
turning.
 Set programme selector switch to trans-
port run.
 Stand on platform and operate safety
switch.
 Set the drive direction using the drive
direction button at the operator console.
 Determine the driving speed by press-
ing the drive pedal.
 Stop the machine: Release the drive
pedal.
Note:
The direction of travel can also be changed
while driving. This way even very dull spots
can be polished by driving back and forth
several times.
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.
 Allow machine to cool down at least for
15 minutes.
 Turn the programme switch to "OFF",
wait for a short period of time and turn it
back to the desired programme.
ATTENTION
Risk of damage. Only use the recommend-
ed detergents. With other detergents, the
operator bears the increased risk regarding
the operational safety, risk of accident and
reduced service life of the appliance. Only
use detergents that are free of solvents, hy-
drochloric acid and hydrofluoric acid.
Follow the safety instructions for using de-
tergents.
Note:
Do not use highly foaming detergents.
 Connect the water hose to the connec-
tion neck on the filling system.
 Open water supply (maximum 60 °C).
Once the maximum fill level is reached,
the built-in floater valve will stop the wa-
ter inflow.
 Shut off water supply.
 Remove the water hose.
 Pour in detergent.
Note:
If detergent is added to the detergent tank
first before the water, this can result in a for-
mation of a lot of foam.
Detergent is added to the fresh water on
the way to the cleaning head with the help
of a dosaging device.
 Place the detergent bottle into the de-
vice.
 Close the bottle lid.
 Insert the suction hose of the dosaging
equipment into the bottle.
Note:
The dosing unit can be used to add 3% de-
tergent at maximum. With higher dosage
the detergent must be put into the fresh wa-
ter tank.
ATTENTION
Risk of clogging due to dried detergent
when the detergent is added to the fresh
water tank of the Dose version. The flow
meter of the dosing equipment can aggluti-
nate on account of drying detergent and
hamper the functioning of the dosing equip-
ment. Subsequently rinse the fresh water
tank and the device with clear water. For
rinsing, select cleaning programme with
application of water at the programme se-
lector switch. Set the water quantity to the
highest value, set the detergent dosing unit
to 0%
Note:
The appliance is equipped with a fresh wa-
ter indicator in the display. If the fresh water
tank is empty, the function of adding deter-
gent gets deactivated. The cleaning head
continues to work without liquid supply.
Parameters for the different cleaning pro-
grammes are preset in the appliance.
Depending on the authorisation of the yel-
low Intelligent Key, individual parameters
can be changed.
The modification of the parameters is only
valid until another cleaning programme is
selected via the programme selection
switch.
If you wish to permanently change the pa-
rameters, you must use a grey Intelligent
Key. This adjustment procedure is de-
scribed in the section "Grey Intelligent
Key“.
Note:
Almost all displayed text regarding param-
eter adjustment is self-explanatory. The
only exception is the parameter FACT:
– Fine Clean: Lower brush speed for re-
moving the grey film on fine stone
floors.
– Whisper Clean: Medium brush speed
for regular cleaning with reduced noise
level.
– Power Clean: High brush speed for pol-
ishing, crystallising and sweeping.
 Turn the program selection switch to
the desired cleaning program.
 Turn the info button until the desired pa-
rameter is displayed.
 Press Info button - the set value blinks.
 Set the desired value by turning the info
button.
