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.

SAFETY AND FAULTS
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.
PREPARATION FOR USE
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.
Micro switch:
Micro switch to shut off all the functions when the tank is in the upright position. (SEMKO APPROVAL)
20
Push the straight end of the squeegee hose onto the tank inlet pipe which protrudes through a slot in the lower rear panel.

PREPARATION FOR USE
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.

MAINTENANCE
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.

MAINTENANCE
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.

PREPARATION FOR USE
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.

Page 10
PREPARATION FOR USE
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.
CHANGING BRUSHES
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.
Drive the machine forward by holding the hand­grips, 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.
8
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.
17
Page 11
CHANGING BRUSHES
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.
PREPARATION FOR USE
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.
Move the machine backward by rolling the traction control rearward until the brushes are visible in front of the machine.
16
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.

Page 12
SCRUBBING AND DRYING OPERATION
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.
SCRUBBING AND DRYING OPERATION
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.
Switch the machine on by turning the key in the key-switch a quarter turn clockwise.
10
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.

Page 13
SCRUBBING AND DRYING OPERATION
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.
TRAVEL DIRECTION
FLOOR LEVEL
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.
SCRUBBING AND DRYING OPERATION
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.
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.
14
Drive the machine forward by holding the hand­grips. And turning the thumb wheels.
11
Page 14
SCRUBBING AND DRYING OPERATION
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.
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.
SCRUBBING AND DRYING OPERATION
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.
A
B
Lower the squeegee to the floor.
