1.1 General Safety Information
Apart from the instructions contained in
this manual, the general safety instruc-
tions and accident prevention regula-
tions, as imposed by law will have to be
complied with. Do not put the Manual
aside without reading it even if you used
similar cleaning machines before. Take
time to read now and save time later.
Machines with known defects must not
be used. It will be of essence to make
yourself familiar with all accessories
and controls, as well as their functions,
before you start working. Avoid the
mess of having to read this book while
trying to run the machine.
Using the machine in areas with explo-
sion hazard is prohibited. The machine
may be used only for cleaning of hard
floorings and for operation on level
ground with a maximum inclination of
up to 2%.
Use the following 16“-Pads and Dust
Bags:
- Polishing Pad peach, PN.: 7856.05
- Polishing Pad jackeroo, PN.: 7853.05
- Polishing Pad champ., PN.: 7854.05

Notethefollowingsafety
information:
- Before use of the machine, check
the Cleanserv PB51/2000 for per-
fect condition and operational
safety.
- The operator has to use the ma-
chine within its design limits.
- This machine has been designed
for dry use. Do not use or store the
machine outdoor or under wet
conditions.
- Do not exceed the maximum incli-
nation of 10% for transport rides
(e.g. on ramps). Do not take the
machine up a ramp in forward
mode. Uphill ride must not exceed
a duration of 2 minutes and has to
be executed with outmost care (Do
not drive on wet, oily or soiled
ramps).
- The operator of the machine has to
wear firm, closed-toed shoes with

1.4 Operation/Safety Information
The Cleanserv PB51/2000 may be run
by qualified personnel only; such per-
sonnelwillhavetohaveevidencedtheir
qualification for running the machine to
the owner or his authorised representa-
tive; operators explicitly will have to be
instructed by the owner or his author-
ized representative to use the machine.
Never leave the machine unattended
before the motors are off and the ma-
chine is protected against unintended
movements. To preclude unauthorised
use of the machine, switch the machine
off and pull the key.
Shut down the motors before transport
of the Cleanserv PB51/2000.
During operation the machine, the oper-
ator has to take account of local condi-
tionsandwhen workinghehas to watch
out for other persons, especially chil-
dren.
Note the following oper-
ating information:
The machine may be used for cleaning
such surfaces approved by the owner
or this authorised representative.
- Do not use the machine on floors
which are not suitable for the ultra-
high speed process (speed of
- 2000rpm max.) such as uneven or
softflooring. The high speed ofthe
machine generates a low pressure
at the pad by which the flooring
may loosen and be thrown off.
- Do not use damaged pads. The
Cleanserv PB51/2000 has not been
designed for collection of dusts
which are hazardous to health or
explosive.
- Never collect explosive fluids, un-
diluted acids and solvents. This in-
cludes gasoline, paint thinners or
fuel oil, which - when penetrating
the air being taken in - may form
explosive vapours or mixtures;
moreoveracetone,undiluted acids
and solvents if they should be ag-
gressive to material used with the
machine.
- Do not get in the near of rotating
parts during operation of the ma-
chine.
- Objects lying on the floor may be
thrown up into the air in the area of
the high-speed pads. Make sure to
remove such objects before opera-
tion.

First Operation
1.2 Before Work
1. Firstoperation of thebatterysystem,
(see page 14).
2. Make sure that the flooring is appro-
priate for being polished in UHS pro-
cedure (pad speed up to 2000rpm
max.)
3. Make sure that adequate pads for
this procedure have been fitted and
pad centring tightened.
4. Check the pad condition and its
thickness in regular intervals. Imme-
diately replace damaged pads (see
page 29).
5. Check all connections of the dust
collection system as well as the dust
bag condition (see page 31).
6. Set polishing head into its transport
position and ride to the surface to be
polished (see page 21).
7. This surface has to be clean, level
and free from objects.
1.3 Switch the machine on
1. Switch the machine on by the key
switch. Check emergency switch
and release if required.
2. Check battery condition (see page
18).
3. Set polishing head into working posi-
tion (see page 21).
4. Use direction switch to select the rid-
ing direction.
5. Press the levers to start-up.
6. Check pad ground pressure (see
page 20).
7. Adjust riding speed (see page 19).
Move the machine upon
switching ON! Never let
the machine run on the
spot! The floor may be
damaged by such high
speed of the pads.
1.4 End of work
1. Depress pedal tolift-upthe paddrive
and let the pedal arm catch.
2. Switch off key switch and pull key.
3. Clean machine by mild detergent

teries is checked and shown by indica-
tor
(Fig. 7/2) after approx. 20 seconds.
Seven yellow lighting LEDs indicate a
fully
charged battery. As battery discharges,
the LEDs are extinguishing from the
right to the left. Shortly before battery
discharge, the left yellow LED flashes.
Then flashes the red LED and signals
end of function. Immediately re-charge
batteries!

Operation
1.2 Adjust Pad Ground Pressure
Adapt the pad speed to the type of floor-
ing to be polished. The adjustment
screw (Fig. 9/1) for pad ground pres-
sure is located on the control panel.
Proceed as follows for pad speed ad-
justment
• Turn adjustment screw counter-
clockwise to increase pad ground
pressure.
• Turn adjustment screw clockwise to
decrease pad ground pressure.
Optimum operating condition of the pol-
ishingmachineismaintained as longas
the pad indication (Fig. 9/1) remains in
the green LED zone.
Do not let the machine
run on the spot for a
longer time.
Always move the machine upon switch-
ing on in order to avoid possible
damaging of the floor. Increase or re-
ducepadgroundpressureonlyafterthe
machine has run and moved.
If pad pressure indication attains the
red zone decrease pad ground pres-
sure. Should the machine be operated
in the red zone for a longer period, the
pad drive will be overloaded and the
70A fuse activated.
Check the pad ground pressure:
Constantly check the pad ground pres-
sure indication (Fig. 8/1)
during polishing and do not exceed
ground pressure in order to shorten the
working cycle of one battery charge.
Avoid the red zone!
