Operation

DANGER
Risk of injury. Do not used the device with-
out an overhead guard to protect against
falling objects in areas in which there is a
possibility of operators being stuck by fall-
ing objects.
Note:
Press emergency-stop switch to immedi-
ately switch off all functions of the machine.
Check parking brake
DANGER
Risk of accident. Prior to every operation,
the parking brake must be checked for
proper function on a level ground.
 Take the seating position.
 Release emergency-stop button by
turning.
 Set the key switch to "1".
 Select travel direction.
 Gently depress drive pedal.
 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 an au-
dible manner. Switch off the machine
and call the aftersales service if the
above-mentioned events do not occur.
Driving
DANGER
Risk of accident. If the device does no longer
show any braking effect, proceed as follows:
 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.
 Switch off the machine only after it comes
to a complete halt (on an even surface)
and call up the aftersales service!
 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%.
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 surfaces.
Danger of tipping with excessive sideways tilt.
 The gradient perpendicular to the direc-
tion of travel should not exceed 10%.

Driving
 Release emergency-stop button by
turning.
 Sit on the seat and set main switch to
"1".
 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.
Display
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 lev-
el in the fresh water tank (lasts for 6
seconds).
„OpHrs xxxxxhxxm+" (Classic model):
Operating hours (lasts for 6 seconds)
– "Battery: E-----F": Charging status of
battery.
Overload
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 main switch to "0" and turn it
back to "1".
Filling in detergents

ATTENTION
Risk of damage. Only use the recommend-
ed detergents. With other detergents, the
operator bears the increased risk regarding
the operational safety and danger of acci-
dent.
Only use detergents that are free from sol-
vents, hydrochloric acid and hydrofluoric
acid.
CAUTION
Follow the safety instructions for using de-
tergents.
Note:
Do not use highly foaming detergents.

Fresh water
 Open the cover of the fresh water reser-
voir.
 Fill fresh water (max. 60 °C) until 15 mm
below the upper edge of the tank.
 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.
 Close the cover of the fresh water res-
ervoir.
Note:
Fill up the fresh water tank completely prior
to the initial start-up to bleed the water pipe
system.
Filling system (optional)
 Connect the water hose to the connec-
tion neck on the filling system.
 Open the water supply.
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.
Metering system (only Dose model)
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 appliance with clear water. For
rinsing, select cleaning programme with
