HOUR METER
The machine is equipped with an hour meter located
on the same display (1) of the battery charge level
indicator. Keeping the button (13) pressed, the rst data
indicates the
ADJUSTMENT OF THE SQUEEGEE
In order to have a perfect drying result through
the squeegee, the rear rubber must have the
lower bending uniformly adjusted in all its length.
For the adjustment, it is necessary to put oneself
in working condition and therefore the suction motor has to be switched on and the brushes have to
function together with the detergent solution.
The lower part of the rubber is too much bent
Take off the pressure rotating the wing nut (6)
counterclockwise.
The lower part of the rubber is not much bent
Increase the pressure rotating the wing nut (6)
clockwise. Check that the wheels which adjust the
height do not rest on the oor, in this case adjust
them as indicated in paragraph “Height adjustment”.
10
Page 11
The bending is not uniform
Adjust the squeegee inclination rotating counterclockwise the wing nut (7) to increase the bending
in the central part, or clockwise to increase the
bending on the extremities.
Height adjustment
Once that the pressure and inclination of the
squeegee have been adjusted, it is necessary to
x this optimum condition making touch slightly
the wheels onto the oor. Rotate counterclockwise
the registers (8) to lower the wheels or clockwise
to raise them. Both wheels must be adjusted in
the same measure.
ATTENTION:
Every type of oor requires a specic adjustment.
For example, concrete oors (where the friction
results to be high) need little pressure, while
smooth oors (ceramics) need higher pressure.
If the cleaning operations are made always on the
same type of oor, the adjustment can change
only in function of the rubber wear.
ADJUSTMENT HEIGHT SIDE RUBBERS
To adjust the side rubbers, it is necessary to act
upon the adjusting screws (1) and (2) after having
loosened the upper blocking nuts. Unscrewing,
the rubber lowers, while screwing down, the rubber is lifted. The reason of the adjustment is to
obtain an uniform bending.
Having nished the adjustment, tighten the blocking nuts to x the position.
ATTENTION:
This operation must be carried out using gloves
to protect from contact with dangerous solutions.
2. Unblock the bar of the side rubber after having
released the knob (1).
3. Open the bar of the side rubber (2) as shown
in the gure.
4. Extract the support plate (3) of the brushes
pulling it outwards by holding its handle.
5. Extract the brush (4).
7. Place the support plate (3) into its position, then
put back the bar of the side rubber (2) blocking it with
the knob (1).
ATTENTION:
The brushes must be inserted easily without using
tools in order not to damage or force them.
Use only brushes supplied with the machine or the
ones indicated in the paragraph “RECOMMENDED
BRUSHES”. The use of other brushes can compromise the good washing result.
FLOOR CLEANING
RECOVERY TANK
Check that the cover of the suction lter (1) is correctly secured, after rotating the levers (2) and that
the suction motor hose (3) is correctly connected to
it.
Verify also that the squeegee hose couplings (4/5)
are correctly inserted into their seats and that the
exhaust hose plug (6) placed in the rear part of the
machine is well closed.
BRUSHES ASSEMBLY AND DISASSEMBLY
Normally, the machine is delivered with the
brushes assembled.
To assemble and disassemble the brushes on
both sides of the machine:
1. Make sure the machine is switched off and with
the brushes base in up position (lifted).
ATTENTION:
To carry out brushes assembly operations with
the electric supply on, may cause damages to
hands.
6. During the reassembly of the brush (4), insert
it into the brush base from the part where the
seat is deeper (about 1.5” (40mm)). The opposite
part with a depth of about .5” (13,5mm) has to
look towards the support plate.
11
DETERGENT SOLUTION TANK
The capacity of the detergent solution tank is indicated in the technical data.
Open the screw plug placed in the left part of the ma-
chine and ll the detergent solution tank with clean
water at a maximum temperature of 50°C (122°F).
Add the liquid detergent in the percentage and conditions foreseen by the manufacturer. To avoid excessive foam presence, which could cause problems to
the suction motor, use the minimum percentage of
detergent. Screw down the plug to close the tank.
Page 12
ATTENTION:
Use always low foam detergent. To avoid foam
pres¬ence, before starting working operation,
introduce into the recovery tank a minimum
quantity of anti-foam product.
Never use pure acid.
3SD SYSTEM SOLUTION SAVING SYSTEM
DISPENSER (OPTIONAL)
The system permits the predetermined dosing of the detergent percentage which will be
mixed with the water of the solution tank.
The system consists of a dual hydraulic circuit,
one for the water and one for the detergent,
each one equipped with a suitable pump.
The detergent is contained in a tank with a capacity of 2 gallons (8 litres), placed in the front
part of the machine.
The tank is transparent, to enable the visualization of the detergent level.
Pressing once the push button (A) on the instrument board, on the display (1) the indicator
shows the detergent percentage which is being
used.
Pressing the same push button in succession, six different possibilities of setting can be
selected and the display (1) visualizes always
the percentage.
The indication of the level corresponds to the
following detergent percentages in the water:
d0 = 0 %
d1 = 0,3 %
d2 = 0,6 %
d3 = 1,2 %
d4 = 2,4 %
d5 = 4,5 %
The last dosing adjustment set remains stored
by the system also with the machine stopped.
The dosing adjustment can be made only with
the brushes moving (during operation), so that
the dosing ratio cannot be modied accidentally.
The water ow is adjusted through the 8-way
commutator (B): one OFF position and 7 operating positions from a minimum of .3 gallon
(1,2 litres)/min to a maximum of 1 gallon (3,7
lit)res/min.
In OFF position both the water ow and its
relative detergent ow is interrupted.
NOTE: the detergent percentage in the water
is in any case always constant independently
from the level course of the water set.
The water ow, besides from being connected
to the set position through the commutator, is
also proportional to the machine speed (position of the accelerator pedal).
In this way, having to reduce the speed near
curves or in presence of difcult areas, a
useless water waste is avoided and simultaneously the drying is improved, because the
squeegee picks up always the same solution
quantity.
When the commutator (B) is in OFF position,
an auxiliary water system can be activated,
that permits the traditional use of the machine
and therefore the lling of the solution tank with
water and detergent without using the system
and therefore without the use of the pumps.
In this case it is necessary to open and adjust
manually a solution valve (C) placed un-der the
machine. In this situation the push button (A)
handles the command of the solenoid valve in
manual function.
NOTE: at the end of each use of the machine
in the traditional mode (without dosing system),
to return to use the dosing system again, it
is necessary to close the solution valve (C),
otherwise the proportions water and detergent
are not anymore the predetermined ones.
NOTE: if the automatic dosing system is not
being used for a long time, it is possible that
the hoses of the detergent circuit are emptied
and therefore at the rst use, the detergent
begins to come out onto the brushes with a
certain delay compared to the water outlet.
Through the solution valve (D) it is possible to
empty the detergent tank and to recover the
detergent.

ations, it is sufcient to release the accelerator
pedal, because the machine has got an electronic
brake system. To restart, press again the
accelerator pedal.
EMERGENCY-PARKING BRAKE
In case of an emergency press the pedal of the
emergency and parking brake (1) placed on
the left side.
To insert the parking brake press the brake pedal
(1) and simultaneously move downwards the lever
(2) placed on the left side of the steering column.
On the instrument board the signal lamp (15)
comes on which signals that the parking brake is
inserted.
To release the parking brake press the brake
pedal (1).
AUTOMATIC SQUEEGEE LIFTING WHEN
GOING BACKWARDS
Selecting the backwards movement the
squeegee is brought automatically to the upper
position. It will then lower again in the following
forward movement.
This happens both in automatic as in manual
mode in order to protect the integrity of the
squeegee.
WORKING IN AUTOMATIC MODE
The automatic operation is useful to simplify the
operator’s work.
1. Activate the machine (see under paragraph
“STARTING OF THE MACHINE”).
2. Pressing the push button (6) the automatic
(AUTO) functioning is chosen. When the signal
lamp (7) is on, then the machine is functioning
in automatic (AUTO) mode.
3. Check that the knob of the solution valve (27)
is in the position of optimum ow, depending on
the type of oor and the type of dirt (see under
the paragraph “FLOW ADJUSTMENT OF THE
DETERGENT SOLUTION”).
4. Position the selector (28) forward to choose
the forward drive.
5. Adjust the movement speed in forward with
the push button (21) (see under paragraph
"FORWARD AND BACKWARD MOVEMENT").
6. Pressing the accelerator pedal, the machine
begins to proceed and in automatic mode all
the working functions are activated. In fact,
automatically both the brushes base as the
squeegee go down, the brushes begin to turn,
the solenoid valve opens to permit the deter-
gent solution to ow down onto the brushes
and the suction system is activated to recover
the dirty water from the oor.
Positioning backwards the selector (28) to
choose the rear drive and pressing the accelerator pedal the rear drive starts, the squeegee
lifts automatically and will then return to lower
itself during the next for-ward movement.
If the accelerator pedal is released for more
than 3 seconds, automatically all the functions
are being switched off and both the brushes
base as the squeegee are being lifted.
Pressing again the pedal, the machine starts to
move again and in automatic mode all the
working functions are reactivated.
WORKING IN MANUAL MODE
The manual model is useful when, in special cases,
it is necessary to carry out separately only the wash-
ing with the brushes or only the drying of the oor.
ATTENTION:
The washing and drying functions, when they
are not carried out simultaneously, represent an
improper use of the machine (see under paragraph
“GENERAL RULES OF SECURITY”). If they are
carried out separately, it is necessary to forbid the
working areas to the passage of non-authorized
personnel and to signal the areas of moist oors
with suitable signs.
1. Activate the machine (see under paragraph
“STARTING OF THE MACHINE”).
2. Pressing the push button (3) the functioning of
manual (MAN) mode is chosen. When the signal
lamp (2) is on, then the machine is functioning in
manual (MAN) mode.
TO CARRY OUT THE WASHING WITH ONLY THE
BRUSHES:
1. Check that the knob of the solution valve (27) is in
the position of optimum ow, depending on the type
of oor and the type of dirt (see under the paragraph
“FLOW ADJUSTMENT OF THE DETERGENT
SOLUTION”).
2. Press the push button (17) of up/down of the
brushes base to lower the brushes. Once that it is
lowered, the brushes begin to turn. The signal lamp
(16) indicates that the brushes base is lowering or
lifting, while the signal lamp (18) signals that the
brushes are turning.
3. Press the switch (19) to open the solenoid valve
and permit the detergent solution to lower onto
the brushes. The signal lamp (20) will come on, to
indicate that the solenoid valve is open.
13
Page 14
TO CARRY OUT THE FUNCTION OF ONLY
DRYING:
1. Press the push button (11) of up/down squeegee to lower the squeegee. The signal lamp (12)
indicates that the squeegee is lowering or lifting.
2. Press the switch (9) of the suction motor to
start the suction system. The signal lamp (8)
indicates that the machine is drying.
Position the selector (28) forward to choose the
forward drive.
Adjust the movement speed in forward with the
push button (21) (see under paragraph "FORWARD AND BACKWARD MOVEMENT”).
Pressing the accelerator pedal, the machine
begins to proceed forward and to work according
to the set functions.
ATTENTION:
In manual mode every function of the machine
has to be activated or deactivated manually.
ADJUSTMENT OF THE BRUSHES PRESSURE
Both in automatic as in manual mode it is
possible through the knob (10) to adjust the
brushes pressure on the oor in eight established
levels. During the operation, we can visualize on
the display (1) the value in per percentage of the
electric absorption of the brushes motor by pressing the button (14).
The adjustment in this mode is done both in automatic and manual operation.
ATTENTION:
In order not to overload the brushes motor, it is
convenient to reduce the brushes pressure going
from smooth oors to rough ones (ex. concrete).
The presence on the display (1) of a blinking
warning from P2 to P8 indicates that the pressure
level set determines an overload of the brushes
motor. It is therefore necessary to reduce the
pressure up to the level where the blinking
warning stops.
STOP OF THE MACHINE AFTER CLEANING
OPERATION
IN AUTOMATIC OR MANUAL WORKING
MODE:
1. A the end of the washing cycle, pressing
the push button (5), the functioning of BREAK
WASHING is chosen. When the signal lamp (4) is
on, then the machine is in the functioning mode
BREAK WASHING. In this way automatically the
solenoid valve shuts down, the brushes are lifted
slightly (a few millimeters) continuing to turn for
about 10 seconds (drying phase of the brushes)
and the collection box drains the exceeding water
to the oor; then, the washing group lifts completely while the squeegee continues to remain in
working position with the suction motor on, after
5 seconds the squeegee lifts and when it reaches
the highest position, also the suction motor stops,
with a delay of another 5 seconds.
WORKING ADJUSTMENTS
Both in automatic as in manual mode, during the
rst metres check:
1. that the squeegee adjustment guarantees a
perfect drying result (see under paragraph “ADJUSTMENT OF THE SQUEEGEE”).
2. that the adjustment of the detergent solution
ow is sufcient to wet the oor uniformly
avoiding the leakage of detergent from the
splash guards (see under paragraph “FLOW ADJUSTMENT OF THE DETERGENT SOLUTION”).
3. that the brushes pressure permits an efcient
washing action in function of the dirt and the
speed (see under paragraph “ADJUSTMENT OF
THE BRUSHES PRES-SURE”).
FLOW ADJUSTMENT OF THE DETERGENT
SOLUTION
To adjust the detergent solution quantity that
ows down onto the brushes it is necessary to act
upon the solution valve knob (27) placed on the
right of the steering column, rotating counterclockwise to increase it and clockwise to reduce it up
to close the ow.
ELECTRIC PROTECTION
The machine is equipped with an electronic
system of protection for all components that carry
out functions of power or control. This device
blocks the defective component and indicates
on the display (1) the corresponding alarm from
”AL01” to “AL20”.
ATTENTION:
To restore the functioning of the component, turn
off and on again the machine acting upon the key
switch. If the problem persists, please contact the
authorized technical assistance.
OVERFLOW DEVICE
In order to avoid serious damages to the suction
motor, the machine is equipped with a
mechanical oat that intervenes when the
recovery tank is full, closing the air ow of the
suction. The machines equipped with electric
oat (optional), the switching off of the suction
motor and its signal lamp (12) happens in automatic mode.
When this happens, it is necessary to empty the
recovery tank (see under paragraph “RECOVERY
TANK EMPTYING AND CLEANING”).
NOTE: all these phases are carried out with
the machine operating, so that the squeegee
can dry the interested cleaning area from the
“drying phase of the brushes” and furthermore can dry the suction hose of its dirty water. At any time it is possible to interrupt the
proce-dure BREAK WASHING by stopping the
drive.
2. During the phase of BREAK WASHING, when
the accelerator pedal is released for more than 3
seconds, the squeegee raises itself and the
suction switches off automati-cally.
3. After three seconds, the accelerator can be
pressed again, if a machine's transfer has to be
made (you can anyway make the transfer even if
the pedal is not lifted once that 20 seconds have
passed).
4. Turn the switch key counterclockwise to switch
off the machine.
5. Insert the parking brake (see under paragraph
“EMERGENCY-PARKING BRAKE”).
ATTENTION:
The mode (BREAK WASHING) is specic for the
transfer at the end of the cleaning operation.
Starting again the cleaning operation:
A. by pressing the push button (6) the automatic
(AUTO) functioning is chosen to start working in
automatic mode.
14
Page 15
B. by pressing the push button (3) the manual
(MAN) functioning is chosen to start working in
manual mode and all functions have to be reestablished manually.

RECOMMENDED BRUSHES
Brushes must be chosen depending on type of oor and dirt to be removed.
The employed material and the bristles diameter are the elements that distinguish different types of brushes.
BRISTLES THICKNESS
MATERIAL CHARACTERISTICS
PPL (Polypropylene) Good wear resistance. Maintains characteristics with hot water up to 50°C(122°F). It is not hygroscopic.
NYLON Excellent wear resistance, even with hot water. It is hygroscopic.
TYNEX Nylon bristles with grains of abrasive material. Use with caution in order not to mark the oor or ruin the polishing.
BRISTLES THICKNESS Thicker bristles are more rigid and must be used on smooth oor or oor with small joints. On irregular oors with deep
joints or relieves, it is recommended to use softer bristles which penetrate more easily and deeper. Please be aware that when brush bristles are worn
out and therefore too small, they become rigid and unable to penetrate and clean deeper. This may also happen with thicker bristles creating brush
vibration.
