INTRODUCTION AND WARNINGS
1
INTRODUCTION
This manual is a guide to the efficient use of the machine and also contains practical information concerning the
functioning, adjustments and user maintenance of your new scrubber/drier. Your machine has been designed and
constructed to ensure maximum performarnce 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 functioning 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
operator position. If you should need any further information concerning the machine, please do not hesitate to contact
either Electrolux Euroclean or our 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
functioning 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 non-observance of the most elementary safety rules. An alert and cautious 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 either its battery or mains supply before any servicing or
adjustment of operational parts be carried out. Ensure that any assistant is clear of the machine and that covers are closed
before switching on.
GENERAL SAFETY RULES
The rules below have to be followed carefully in order to
avoid damages to the operator and to the machine.
- Read the labels carefully on the machine; Do not cover
them for any reason and replace them immediately if
damaged.
- The socket for the power supply must be fitted with a
standard earthing (ground) system.
- With the brushes in working position, avoid touching or
passing over the mains cable. Avoid damaging by

MAINTENANCE
Periodically remove the filter inside the dirty water
tank, scrub it with a stiff brush under running
water to remove any accumulated foreign matter.
Note: This operation is very important to
prevent the reduction of the suction
(drying) capability of the squeegee.
The plastic buffles can be easily removed for the
best cleaning of the tanks.
The three solenoid valve bodies may be removed
by turning them through 90 degrees and lifting
them away to reveal the plunger and seating of
each valve. These should be cleaned of scale and
of any other foreign matter.

when handling battery liquid
as it is corrosive. If it should
come into contact with skin
or eyes, wash abundantly
with water and consult a
doctor.
Recharge batteries when necessary with a
specific battery charger.
If the batteries are of the wet type open all the
battery caps before starting the recharge.
The recarge must be done in a well ventilated
area.
MAINTENANCE
* - This function is not available on model AW445
(both battery and cable versions).
**- This function is not available on models AW445
and AW445 T (both battery and cable versions).

To replace the brushes (or to clean them) carry out
the following sequence of operations:
The machine must be switched on but all functions
switched off; it means that the squeegee must be
lifted.
Raise the brush unit by pressing down the relevant
pedal and latching it in its lowest position.
Press the brush release push button Amomentarily
(1 or 2 seconds) and the brushes will be unloaded
from the machine.
Move the machine backward by rolling the drive
control thumb wheels rearward until the brushes
are visible in front of the machine.
(pull the machine that is not equipped with the
drive motor).
Clean carefully the three pins of each brush to
keep efficient the Click ON/Click OFF function.
To mount the new brushes see the “Preparation for
use” at page 10.

PREPARATION FOR USE
For models working with batteries follow the
instructions below, whereas in the case of mains
operated models the transformer (or mains unit)
has already been placed inside the machine and
needs no further installation.
The batteries are supplied without liquid, therefore
they must be filled up with the appropriate acid
solution (concentration greater than 30%) before
they can be used.
Take special care when handling the acid
solution as it is corrosive. If it should
come into contact with skin or eyes,
wash abundantly with water and consult
a doctor.
The AW445,AW445 T and AW455 T
models use two 12 Volt batteries connected
in series.
The AW465 and AW475 models use four 6
Volt batteries connected in series. Please study
the applicable illustration then fit the batteries
and connect the supplied links as indicated.
When the battery set has been properly charged
plug the battery socket into the machine as
shown. Lower the tank unit to safely cover
exposed working parts.
17
Remove the cap from the hose unscrewing the
knob and empty the tank.
There is a water level sensor also in the tank for
the clean water (A).
When the tank is going to be empty the red light
Bwill turn-on; 80 seconds later the automatic
switch “off” of the water flow (electrovalves and
water pump) will occur and a beep will be
heared.
The display Anormally shows the voltage of the
battery (or the output voltage of the transformer
unit for the machines with mains cable).
By pushing button Bone time the working hours
of the machine will be shown (hour meter); by
pushing the button Btwo times the working
minutes will be shown. Push the third time or wait
10 seconds to restore the battery voltage.

PREPARATION FOR USE
After filling the batteries must stand for at least 1
hour and then they must be filled up if necessary.
After one further hour the batteries must be
recharged: remove the battery caps during the
recharge operation.
The new batteries will gradually “run in “ and will
increase their capacity.
The maximum capacity will be achieved in about
10 charge/discharge cycles.
When necessary the batteries must be charged
using an appropriate battery charger. Remove the
battery caps during the charging operation.
Check that the Volt and Hertz
reading of the mains supply
correspond to those of the battery
charger.
For further information about battery
maintenance see also the relevant
paragraph.
16
Also the tilting of the squeegee can be adjusted
by means of the dedicated knob, in order to
improve the drying capability of the machine.
Move the machine slowly forward, and adjust the
squeegee pressure and tilting controls until the lips
bend over evenly as illustrated below.
The lips must be replaced when they become
feather edged or torn.
When the recovery tank (dirty water) will be filled
the red light Awill turn “on”; within 5 seconds the
automatic switch-off of the suction motor will also
occur.
In order to be able to re-use the machine the
recovery tank must be emptied. Then lift the
squeegee and the brushes by means of the
relevant lever and pedal. Turn the master key OFF
and disconnect the hose.

In the event of a temporary stop (releasing thumb
wheels) the automatic switch-off of the all functions
will occur (AUTOPOWER-OFF).
Turn the thumb wheels in order to restart the
normal operation; all the functions will restart
automatically
(AUTOPOWER-ON).
NOTE: for all versions of model AW445 and
(brush driven model) the rotation of the brush will
make the forward displacement of the machine
easyer. On the same model the “AUTOPOWER-
OFF”/“AUTOPOWER-ON” function is not
available.
The following adjustments can be done on the
machine: increase or reduction of the pressure of
the brushes on the floor by means of the
dedicated rotating knob: the required pressure
will depend on the kind of floor and dirt to be
scrubbed.
NOTE: Set the pressure to the minimum possible
value, consistantly with the kind of dirt to be
cleaned: this will increase the battery working
time.
Increase or reduce of the pressure of the
squeegee on the floor by means of the dedicated
knob: again the required pressure will be different
depending on the kind of floor to be dryed.
SCRUBBING AND DRYING OPERATION

11
Drive the machine forward by holding the hand-
grips, then rolling the thumb wheels forward until
the machine moves completely over the brushes.
To stop release the thumb wheels and they will

SCRUBBING AND DRYING OPERATION
Once the brushes have been locked on, raise the
brush unit by pushing the pedal down and
latching it at its lower position.
Now the machine is ready for use.
Open the tank lid.
Fill the left tank with water to about 75mm (3”)
from the top edge then add the scrubbing
detergent in a quantity to make a dilution
according to its instruction.
Too strong a mix wastes detergent, too weak a
mix will not work efficiently.
The machine is now ready for use; so move off to
the site to be cleaned.

Lower the brushes by pushing the relevant pedal
to the right to unlatch it and bring it to the upper
position: the brush motors, the electrovalves and
the water pump will start automatically in a few
seconds.
The relevant green light indicators will turn “on”
on the control panel.
To increase or reduce the flow of the clean water
to the floor the push buttons A(+ to increase) or B
(- to reduce) can be used.
NOTE: For all the versions of models AW445,
AW 445 T and AW455 T the membrane and
the water pump are optional items.
In any case the pump green light indicator will
turn “ON” when the brushes are lowered.
