INTRODUCTION
This manual is a guide to the efficient use of the machine and also contains practical information
concerning the operational adjustments and user maintenance of your machine. Your machine
has been designed and constructed to ensure maximum performance and ease of operation in
a wide variety of applications.
Before delivery, the machine has been tested in our factory and by our distributor to ensure that
it is delivered to you in perfect condition. To maintain the machine in this condition and
guarantee operation without problems, it is essential that the periodic maintenance operations
indicated in this manual are properly carried out. Before using the machine, carefully read this
manual and keep it within easy reach for your future reference. Indications of “LEFT” and
“RIGHT” are as seen from the operators position.
If you should need any further information concerning the machine, please do not hesitate to
contact either ELECTROLUX EUROCLEAN or your local distributor.
MODIFICATIONS AND IMPROVEMENTS
Electrolux Euroclean aim toward continuous improvement of its machines and reserves the right
to carry out modifications and improvements whenever necessary without being obliged to
update machines which have been sold previously.
SAFETY
You too can avoid accidents.
No accident prevention programme is effective without the total co-operation of the person
directly responsible for the operation of the machine. The majority of accidents which may occur
either during work or transferring the machine from site to site are caused by the nonobservance of the most elementary safety rules. An alert and cautions operator is the best
guarantee against accidents and is more effective than any other part of an accident prevention
programme.
The machine must be switched off and disconnected from its battery any servicing or adjustment
of an operational part is carried out. Ensure that any assistant is clear of the machine and that
protective covers are closed before switching on.

If a battery is fitted, unscrew one of the vent caps to determine if it is filled
with acid which covers the plates and separators.
1. If acid is present then all that is necessary is to
plug the battery connector into the
machine.
2. If the battery is supplied
without liquid, it must be filled
up with acid before it can be
used. Read the leaflet
supplied with the battery
about filling and
maintenance.
3. If no battery is supplied then
this will have to be purchased
separately and fitted. Cable
terminations for the battery take-offs
which will be supplied with the
battery, will have to be fitted to the
connector leads which are supplied with
the machine.

PREPARING A NEW MACHINE
The machine is battery operated.
Depending on the country in which the machine is
supplied three options are possible:
1. Battery supplied and fitted, filled with acid and
ready for use.
2. Battery supplied and fitted but dry.
3. Battery not supplied.
The battery compartment is under the seat. Lift the
seat upwards and over the steering wheel to see
which option applies with your machine.
WARNING: The machine must be
switched off and the battery unplugged.
Remove each solenoid assembly one at a time, by
pulling the two spade connectors away from the
unit then turn the coil through 90° and lift away
along the axis. Wash the rubber diaphragm
clean, wipe the seating with a damp cloth, then
reassemble in reverse order.
Repeat this operation with the other three valves.
Every 50 hours as seen from the run time display
on the panel, inject four pump strokes of
molybdenum gear grease from a high pressure
grease gun (the type used for cars) into each of
the greasing points of the traction wheel.
To gain access to the fuses, remove the right side
panel.

USER MAINTENANCE
WARNING: The machine must be
switched off and the battery unplugged.
Unscrew the clean tank filter and scrub with a stiff
brush to remove all accumulated foreign matter
and lime build-up.
When the recovery tank is emptied lift out the
filter, remove any accumulated rubbish and wash
under running water.
If the liquid flow to the brushes deteriorates then
the solenoid valve diaphragms should be
cleaned. To gain access to these tip back the
empty tank unit to its fullest extent (it is limited by a
supporting gas spring).
PREPARING A NEW MACHINE
Take special care when handling acid as it is corrosive, if it should come into contact with skin
or eyes, wash abundantly with water and consult a doctor.
The batteries should be charged in a well ventilated area with the seat raised, using the charger
supplied or one which matches the battery capacity.
For charging and maintenance operations on the batte ry see the instruction leaflets of both the
battery and the charger.
It is recommended that battery specialists deal with the commissioning of new batteries.
BEFORE OPERATING THE MACHINE
The previously slackened magnetic brake must be set
for normal operation.
Screw in the brake tension plate clockwise until the
machine cannot move, turn on the key switch to
“ON”, then gently press the traction accelerator
pedal. The brake should be heard to snap “off” and
with further pressure on the pedal the machine will
move forward. The tension plate should be adjusted
so that from full speed the machine stops within 1.5
metres from the point the pedal is released.
When the braking distance has been set, fit the brake
cover to avoid the ingress of foreign matter.

Whilst the machine is being used take note of the
battery condition indicator, if the red indicator
lights continuously then the machine will shortly
stop scrubbing because the battery has run down
during use to a predetermined level beyond which
battery damage will result. Scrubbing and drying
operations will stop, but traction and the recovery
tank discharge pump will still operate allowing
you to empty the tank and return to your charging
point.
Press the brush motor ON/OFF push button to
start the brushes.
Press “+” to increase or “-” to decrease the brush
pressure.
When the machine is positioned ready for
scrubbing, select the estimated amount of clean
liquid required by pressing the detergent flow
control ON/OFF push. An indicator will light
which can be increased in four steps for varying
the quantity of liquid delivered to the brushes.
NOTE that the liquid will be delivered to the
brushes ONLY when the brushes are rotating and
the machine moving forward. If either the brushes
are switched off or the machine stops moving then
the liquid flow will stop.
USING THE MACHINE
If more liquid flow is required then press the boost
pump ON/OFF push which will double the
amount of flow which is shown by the indicator.
Once the brush motors are running the scrubbing
head can be lowered to the floor with the same
pressure that was previously being used.
This pressure may be changed at any time as
required by pressing the “+” or “-” buttons.
Forward or reverse are obtained by pressing the
right or left sides of the accelerator pedal.
Whilst reversing a bleeper will sound as a
warning signal.
If reversing takes place whilst scrubbing the
squeegee will be automatically lifted from the
floor to avoid damage.
