NOTE

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
operators 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 are carried out. Ensure that any assistant is clear of the machine and that covers are closed
before switching on.
INTRODUCTION

SAFETY AND FAULTS
20
Partially unscrew the two middle levers on the
squeegee. Push the squeegee into the locating
lugs as illustrated and fully tighten the levers.
(pull the lever up to disingage it and make its
rotation free).
Push the coiled end of the squeegee hose fully
home onto the tubular spigot in the centre of the
squeegee.
Push the straight end of the squeegee hose onto
the tank inlet pipe which protrudes through a slot
in the lower rear panel.
Keyswitch/accelerator sequence:
This safety feature prevents the machine from
moving if the machine is accidentally switched on
with either forward or reverse function engaged
(due to machine fault or an operator error).
When this happens the leds on display panel
begin flashing.
Mosfet short circuit:
This safety feature prevents the machine from
moving if the machine is switched on with the the
part of the electronic print card controlling drive
power is in short circuit (in this case the machine
would move immediately at full speed). This
condition is signalled by the 3 voltmeter leds
which start flashing.
Overheating of the electronic print card
cooling vents:
This protection device of the electronic print card
prevents damage to the card itself during
prolonged use of the machine when one of its
functions is overloaded. In this condition the
machine automatically cuts off all its functions
which are then only restored when temperature
returns to normal value. This condition is signalled
by the lighting up in sequence of the 3 voltmeter
leds.
Micro switch:
Micro switch to shut off all the functions when the
tank is in the upright position.

MAINTENANCE
19
For models working with batteries follow
instructions below, whereas in the case of mains
operated models the transformer 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 before they can be used.
Take special care when handling the
acid as it is corrosive, If it should come
into contact with skin or eyes, wash
abundantly with water and consult a
doctor.
The W345B & W355B machines use two 12 volt
batteries, the W365B & W375B machines use
four 6 volt batteries.
Study the
illustrations then fit
the batteries and
connect the links
supplied as
indicated.
Plug the battery
socket into the
machine as shown.
Fold over the flaps
to cover the battery
tops, then lower the
tank unit to safely
cover exposed
working parts.
The three solenoid valve bodies may be removed
by turning them through 45 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.
Regularly inspect the squeegee for damage or
wear to the lips. The lips may be easily replaced
by unscrewing the retaining strips, remove the
lips, replace with new, then screw the cover strips
back again to retain them.
Important:periodically clean the suction
filters; this is very important not to
reduce the suction capability of the
squeegee.

The machine may now be run for trial purposes
but before putting it into service the batteries
should be charged to bring them up to their
maximum capacity.
New batteries will gradually “run in” and
increase in capacity to a maximum in about the
first 10 charge/discharge cycles.
If necessary the batteries should
be charged using an appropriate
battery charger. Remove the
battery caps during the charging
operation.
Check that the Hertz and Voltage
readings of the mains supply
correspond to those of the battery
charger.
BEFORE ANY MAINTENANCE IS CARRIED
OUT THE BATTERY MUST BE UNPLUGGED
OR THE MAINS LEAD UNPLUGGED.
Periodically unscrew the filter inside the scrubbing
detergent tank, scrub whit a stiff brush under
running water to remove any accumulated foreign
matter.
Note: for the models 345-355 it is enough to pull
the filter to remove it. Press the filter to mount it.
For the battery operated models, the level of the
liquid inside batteries must be checked
periodically, and topped up with distilled water
if necessary.
Raise the bonnet, uncover the battery
compartment, remove caps and check level.
Special care should be taken
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 an
appropriate battery charger.

CHANGING BRUSHES
17
Drop the brushes (one or two depending on the
model) roughly side by side in front of the
machine, the actual position does not matter.
Switch the machine on by turning the key in the
key-switch a quarter turn clockwise. Wait
momentarily until the battery condition indicator
above the switch lights.
Note :
The mains machine will have to be plugged in,
the indicator then only shows that power is
available.
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
return to a neutral position. This will ensure the
brushes are fully located under the drive plates.
Position the new brushes roughly side by side on
the floor in front of the machine.
Move the machine forward until the brushes are
pushed along the floor. Release the brush lift/
lower pedal and allow it to settle at its highest
point. Rock the machine forward and back about
50mm (2”) to settle the drive plates into the brush
centers.
Press the brush motor on/off push button to
engage the brushes. Press the brush pedal down
and latch it into its lower position, press the brush
push button again to stop the motors.
The machine is now ready for use again.

Lower the brush unit by pushing the pedal to the
right to unlatch it. Then allow it to rise as far as it
will go. Push the machine forward then back
about 50mm (2”) to ensure the drive has located
in the brushes.
Press the brush “on/off” push button: the indicator
will light and the brush motors will engage the
brushes.
Once the brushes have locked on, raise the brush
unit by pushing the pedal down and latching it at
its lower position.
Press the brush “on/off” push button again (see
previous picture); the green indicator will wait for
the motors to spin down to stop before going out.
Note : The motors do not stop immediately.
The brushes are now loaded onto the machine.
To replace brushes carry out the following
sequence of operations:
The machine should be switched on but all
functions switched off.
Raise the brush unit by pressing down the brush
lift/lower pedal and latching in its lowest position.
Press the brush release push button momentarily
and the brushes at present fitted will be unloaded
from the machine.
Move the machine backward by rolling the
traction control rearward until the brushes are
visible in front of the machine.

SCRUBBING AND DRYING OPERATION

SCRUBBING AND DRYING OPERATION
15
Open the tank lid.
Fill the left tank with water to within 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.
Switch the machine on by turning the key in the
key-switch a quarter turn clockwise.
Unclip the recovery tank emptying hose and
remove the drain plug whilst holding the pipe at
its highest extent, then lower it carefully into a
gully or drain.
Note:
It is against Water Regulations to discharge
detergents into a surface drain, only use a foul
gully or drain.
At the same time as emptying the recovery tank
check if the clean tank requires refilling.
If the clean liquid runs out then it is recommended
that to save time the recovery tank be emptied at
the same time as the clean tank is refilled.
A switch is fitted on the rear panel to the right of
the control handle which controls the drive motor
power. With the switch lever in the up position the
traction motor is disconnected and the machine
may be pushed easily from site to site when the
mains lead is unplugged or when the batteries are
not available.

Press the brush “on/off” push button: the indicator
will light and the brush motors will start.
Lower the brush unit by pushing the pedal to the
right to unlatch it.
Drive the machine forward by holding the hand-
grips. And turning the thumb wheels.
Push the machine slowly forward, and adjust the
squeegee pressure control until the lips bend over
evenly as illustrated below. Then re-adjust the rake
control to make the radius of the squeegee sit
parallel to the floor and the lips bend evenly.
The lips must be replaced when they become
feather edged or torn.
Fully lift the squeegee control lever (just below and
to the right of the machine handle) to lower the
squeegee to a flat floor surface.
If the recovery tank full indicator lights continuosly
for a period of 6 seconds the suction motor will
switch off and the tank will have to be emptied
before continuing the operation.
Note:
Lift the brushes whilst still moving forward then
stop traction, in that order, to avoid “polo rings”.
Lift the squeegee and stop the suction motor. Drive
the machine to an emptying point or use a transfer
trolly to empty the recovery tank.

When the machine is ready for scrubbing select
the estimated amount of clean liquid required by
pressing the detergent flow control on/off push
button; an indicator will light which can be
increased in three steps for varying the quantity of
liquid delivered to the brushes.
If more liquid is required press the boost pump
on/off push button which will double the amount
of flow; this will be shown by the indicator.
Lower the squeegee to the floor.
Press the suction on/off push button.
Start the brushes rotating, move the machine
slowly forward, then immediately lower the
brushes to the floor by lifting the foot pedal. (If the
brushes are allowed to rotate in contact with the
floor without the machine moving then it is likely
to cause “polo rings” on the floor).
Whilst moving forward observe the cleaning
effect on the floor and adjust the detergent flow to
the minimum required whilst being liquid enough
to be picked up by the squeegee. This allows the
liquid to last longer before having to refill the
tank. If too little liquid is used the floor will dry
with a “sludgy” grey look to it.
The height of the drive handle can be adjusted by
turning the knob A.
The speed range can be selected by means of
switch B.
Adjust the brush pressure to the minimum
required; this will assist in using the least amount
of power necessary from the battery which will
then last longer before requiring recharge.

Note:
The liquid will be delivered to the brushes only
when the machine is moving forward and the
brushes are rotating. If either the brushes or the
forward traction are stopped the liquid flow
will stop.
