MATION:
1. The machine model (for example
AdL).
2. The setting of the battery check
card which can be: GE 24 (check
card set for GEL batteries). or
Pb 24 (check card set for lead batter-
ies).
3. The version of the software pro-
gramme of the card (for example 4-6).
4. The batteries charge level indica-
tor is digital and remains xed on the
display. The battery charge level starts
from -100-, which indicates the 100%
of the total charge and decreases
from 10 to 10. When the charge
level reaches -20-, the display starts
blinking, so you are about the end of
working.
ATTENTION:
When the indication -10- appears
blinking, automatically the brushes
stop, while the suction continues to
work. When there are four lines blink-
ing, the suction will also stop auto-
matically. The traction system remains
functioning to enable movement to
transfer the machine to the place
provided for the tank emptying and for
the recharge of the batteries.
SETTING OF THE BATTERY CHECK

setting is modied.
To change from GEL to Lead-Acid,
repeat the procedure pressing button
(2) instead of button (3).
ATTENTION:
As the machine is a 24V model, do not
set the batteries at 36V.
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 (2) pressed, the
rst data indicates the working hours
and after a few seconds the working
minutes are shown.
SQUEEGEE ASSEMBLY
1. Hold the squeegee support (1) lifted
from the oor.
2. Insert the threaded parts of the two
knobs (4) making them slide inside
the two slots on the support placed on
the upper part of the squeegee (2).
3. Put the washers (3) into position,
there are two for each knob, so that
they are assembled one under and
the other on top of the two slots on the
support.
4. Secure the squeegee by rotating
the two knobs (4) clockwise.
5. Insert the squeegee hose (5) into
its coupling, as indicated in the gure.
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
the machine in working condition and
the vacuum 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".
The bending is not uniform
Adjust the squeegee inclination rotat-
ing 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 con-
dition making touch slightly the wheels
onto the oor. Rotate the registers
(8): clockwise to lower the wheels or
counterclockwise to raise them. Both
wheels must be adjusted in the same
measure.
ATTENTION:
Every type of oor requires a specic
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 func-
tion of the rubber wear.
SPLASH GUARD ASSEMBLY
The two splash guards have to be as-
sembled onto the brushes base group
as indicated in the following gures.
Insert the metal strips inside the
suitable slots present on the rubber.
Place the round hole at the extrem-
ity of the strip onto the pin (1) placed
in the front part of the brushes base
group. Secure the strips through the
nut blocking it.
Block the coupling lever (2) in the
rear part of the brushes base group
to the ring placed at the extremity of
the metal strip still free. Please act as
above for both splash guard rubbers.
With the brushes assembled, the
splash guard must slightly touch the
oor.
For the disassembly it is necessary
to proceed inversely with above-men-
tioned operations.

BRUSHES ASSEMBLY
To assemble the brushes it is neces-
sary that the brushes base is in the
lifted position. If it is not lifted, proceed
as follows:
Without the operator seated, turning
the key switch clockwise, the display
comes on and after 3 seconds all
working groups come off automatically
and are lifted from the oor.
Switch off the machine turning the key
counterclockwise.
ATTENTION:
To carry out brushes assembly opera-
tions with the electric supply on, may
cause damages to hands.
With the brushes base group in lifted
position, insert the brushes into their
plate seat underneath the brushes
base turning them until the three metal
buttons are properly seated in their
slots; quickly rotate the brushes to
push the button towards the coupling
spring until they get blocked. The
gure shows the rotating direction for
brushes coupling.
For a longer life of the brushes we
suggest to invert daily their posi-
tion. Whenever brushes become
de¬formed we suggest to reassemble
them in the same position, in order
to avoid the different inclination of
the bristles to cause excessive motor
overload or troublesome vibrations.
ATTENTION:
Use only brushes supplied with the
machine or the ones indicated in
the paragraph “RECOMMENDED
BRUSHES”. The use of other brushes
can compromise the 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.
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 machine and ll the deter-
gent solution tank with clean water
at a maximum temperature of 122°F
(50°C). Add the liquid detergent in the
percentage and conditions recom-
mended by the manufacturer. To avoid
excessive foam, which could cause
problems to the vacuum motor, use
the minimum percentage of detergent.
Screw down the plug to close the tank.
ATTENTION:
Always use low foam detergent. To
avoid foaming, before starting opera-
tions, introduce into the recovery tank
a minimum quantity of anti-foam prod-
uct. 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 detergent is
contained in a transparent tank with a
capacity of 8 liters, placed in the front
part of the machine.
With the brushes moving, pressing
the push button (A) on the instrument
board, on the display (1) the indication
shows the detergent percentage which
is being used.
https://harrissupplyind.com-ToOrderPartsCall608-268-8080

15
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:
d 0.0
d 0.3
d 0.6
d 1.2
d 2.4
d 4.5
The dosing adjustment set remains
stored by the system even with the
machine stopped. The water ow is
adjusted through the 8-way commuta-
tor (B): one OFF position and 7 oper-
ating positions from a minimum of 1,2
liters/min to a maximum of 3,7 liters/
min. In OFF position both the water
ow and its relative detergent ow is
interrupted.
When the commutator (B) is in OFF
position, an auxiliary water system can
be activated, that permits the tradi-
tional use of the machine and there-
fore 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 neces-
sary to open and adjust manually a
solution valve (C) placed under the
machine. In this situation the push but-
ton (A) handles the command of the
solenoid valve in manual function.
NOTE: when restarting the work in
mode 3SD, it is important that the
solution valve (C) is closed, this is to
maintain the predetermined propor-
tions water-detergent.
NOTE: if the automatic dosing system
is not being used for a long time, it is
possible that the hoses of the deter-
gent 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.
STARTING THE MACHINE
A safety device avoids the machine’s
movement if the operator is not seated
correctly on the guiding place.
To switch on the machine:
1. Sit on the seat.
2. Turn the key switch (1) clockwise to
switch on the machine. Automatically,
the machine gets ready in manual
(MAN) mode and in forward movement
with the fast speed (signal lamp 2).
3. Check the charge level of the bat-
teries on the display (3).
4. Pressing the push button (7) the
functioning of BREAK WASHING is
chosen and the transfer operations
of the machine are carried out (see
under paragraph “FORWARD AND
BACKWARD MOVEMENT"). When
the signal lamp (6) is on, then the ma-
chine is in BREAK WASHING mode.
5. Pressing the push button (8) the au-
tomatic (AUTO) functioning is chosen,
while pressing the push button (5), the
functioning of the machine becomes
manual (MAN).
A. When the signal lamp (9) is on, the
machine is functioning in automatic
(AUTO) mode and the machine acti-
vates and deactivates all the working
functions in an automatic mode (see
under paragraph “WORKING IN AU-
TOMATIC MODE”).
B. When the signal lamp (4) is on,
the machine is functioning in manual
(MAN) mode and it is possible to
choose if:
I. To carry out the only transfer of the
machine without activating or deacti-
vating the working functions.
II. To activate separately only the con-
trols relative to the washing function
with the brushes (see under paragraph
“WORKING IN MANUAL MODE”).
III. To activate separately only the con-
trols relative to the drying function with
the squeegee (see under paragraph
“WORKING IN MANUAL MODE”).
ATTENTION:
In manual mode every function of the
machine has to be activated or deacti-
vated manually.
FORWARD AND BACKWARD
MOVEMENT
It is recommended to always carry out
the mere transfer of the machine in
mode (BREAK WASHING).
To proceed to activate the movement
of the machine:
1. Sit on the seat.
2. Turn the key switch (1) clockwise to
switch on the machine.
3. Check the charge level of the bat-
teries on the display (5).
4. Pressing the push button (7) the
functioning of BREAK WASHING is
chosen to carry out the mere transfer
of the machine. In fact, in this mode
the washing functions of the machine
are not working and only the traction
system functions. When the signal
lamp (6) is on, then the machine is in
BREAK WASHING mode.
5. Positioning the selector (8) forward,
the forward drive is chosen, while
positioning it back, the reverse drive is
chosen.
6. Press the accelerator pedal placed
on the right part of the platform to start

8. In backward movement, when the
machine is moving, an intermittent
warning device is activated.
HORN
The machine is equipped with a horn
which is activated pressing the push
button (1).
WORKING BRAKE
To stop the machine during normal
working situations, it is sufcient to re-
lease the accelerator pedal, because
the machine has an electronic brake
system. To restart, press again the ac-
celerator pedal.
PARKING BRAKE
The machine is equipped with a park-
ing brake on the traction motor wheel
that operates at the complete release
of the accelerator pedal or when the
machine is without batteries. In case
of an emergency or simply to stop the
machine, it is sufcient to release the
accelerator pedal. The brake remains
on until the accelerator pedal is
pressed again. When the batteries are
connected and when the key switch
(A) is positioned on 1, with the brake
inserted, the lamp (2) comes on.
MANUAL MOVEMENT OF THE MA-
CHINE
To move the machine manually, it
is necessary to unblock the parking
brake that blocks the traction motor
wheel. To do this, keep the lever (3)
lifted. With the delivery of the machine
we also supply a cord that permits
the lever operation (3). After having
moved the machine, take off the cord
and keep it for eventual re-use.
ATTENTION:
When the parking brake is released
manually, for example when the ma-
chine has to be moved without batter-
ies, avoid slopes and do not park on
them either.
AUTOMATIC SQUEEGEE LIFTING
WHEN GOING BACKWARDS
When the backwards movement is
selected the squeegee is brought
automatically to the upper position. It
will then lower again in the following
forward movement. This happens
both in automatic and 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 MA-
CHINE”).
2. Pressing the push button (3) the au-
tomatic (AUTO) functioning is chosen.
When the signal lamp (4) is on, then
the machine is functioning in automat-
ic (AUTO) mode.
3. Check that the knob of the solution
valve (5) 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 (1) forward to
choose the forward drive.
5. Adjust the movement speed in
forward with the push button (2) (see
under paragraph "FORWARD AND
BACKWARD MOVEMENT").
6. Pressing the accelerator pedal,
the machine begins to move and in
automatic mode all the working func-
tions are activated. Automatically both
the brushes base and the squeegee
go down, the brushes begin to turn,
the solenoid valve opens to permit the
detergent solution to ow down onto
the brushes and the suction system
is activated to recover the dirty water
from the oor.
Move the selector backwards (1) to
choose the reverse drive and pressing
the accelerator pedal the reverse drive
starts, the squeegee lifts automati-
cally and will then lower itself during
the next forward movement. If the
accelerator pedal is released for more
than 3 seconds, automatically all the
functions are switched off and both the
brushes base and the squeegee are
lifted. Pressing the pedal again, the
machine starts to move again and in
automatic mode all the working func-
tions are reactivated.
WORKING IN MANUAL MODE
The manual mode is useful when, in
special cases, it is necessary to carry
out separately only the washing with
the brushes or only the drying of the
oor.
ATTENTION:
The washing and drying functions,
when they are not carried out simul-
taneously, 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 MA-
CHINE”).
https://harrissupplyind.com-ToOrderPartsCall608-268-8080

17
2. Pressing the push button (2) the
functioning of manual (MAN) mode is
chosen. When the signal lamp (1) 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 (8) 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 (6) of up/
down of the brushes base to lower
the brushes. Once it is lowered, the
brushes begin to turn. The blinking sig-
nal lamp (7) indicates that the brushes
base is lowering or lifting (it remains
on when the brushes base is in work-
ing position), while the signal lamp (5)
signals that the brushes are turning.
3. Press the switch (4) to open the so-
lenoid valve and permit the detergent
solution to lower onto the brushes. The
signal lamp (3) will come on, to indi-
cate that the solenoid valve is open.
TO CARRY OUT THE FUNCTION OF
ONLY DRYING:
1. Press the push button (14) of up/
down squeegee to lower the squee-
gee. The blinking signal lamp (13)
indicates that the squeegee is lower-
ing or lifting (it remains on when the
squeegee is in working position).
2. Press the switch (12) of the suc-
tion motor to start the suction system.
The signal lamp (11 indicates that the
machine is drying.
Position the selector (9) forward to
choose the forward drive. Adjust the
movement speed in forward with the
push button (10) (see under para-
graph "FORWARD AND BACKWARD
MOVEMENT”).
Pressing the accelerator pedal, the
machine begins to move forward and
to work according to the set functions.
ATTENTION:
In manual mode every function of the
machine has to be activated or deacti-
vated manually.
WORKING ADJUSTMENTS
Both in automatic and in manual
mode, during the rst feet (metres)
check:
1. that the squeegee adjustment guar-
antees a perfect drying result (see
under paragraph “ADJUSTMENT OF
THE SQUEEGEE”).
2. that the adjustment of the detergent
solution ow is sufcient to wet the
oor uniformly avoiding the leakage of
detergent from the splash guards (see
under paragraph “FLOW ADJUST-
MENT OF THE DETERGENT SOLU-
TION”).
3. that the brushes pressure permits
an efcient washing action in function
of the dirt and the speed (see under
paragraph “ADJUSTMENT OF THE
BRUSHES PRES-SURE”).
FLOW ADJUSTMENT OF THE DE-
TERGENT SOLUTION
To adjust the detergent solution quan-
tity that ows down onto the brushes
it is necessary to rotate the solution
valve knob (1) placed on the right of
the steering column, rotating counter-
clockwise to increase it and clockwise
to reduce it up to close the ow.
It is better to adjust the water ow dur-
ing work and at every adjustment of
the brushes pressure.
ADJUSTMENT OF THE BRUSHES
PRESSURE
Through the knob (4) it is possible to
adjust the brushes pressure onto the
oor in three pre-set pressure levels.
We can visualize on the display (1) the
pressure in kg previously set by press-
ing the push button (3).
The adjustment occurs in this way
both in automatic and in manual mode.
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 visualization of the blinking led (2)
indicates an overload of the brushes
motor. It is therefore necessary to
reduce the pressure up to the level
where the blinking warning stops.
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 ”A1”, “A2” and on.
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.

18
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.
When this happens, it is necessary to
empty the recovery tank (see under
paragraph “RECOVERY TANK EMP-
TYING AND CLEANING”).
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 (1), the func-
tioning of BREAK WASHING is cho-
sen. When the signal lamp (2) is on,
then the machine then the machine
is in BREAK WASHING mode. In this
way automatically the brushes lift, the
solenoid valve shuts down and it is
possible to nish the drying operation
for a total time of about 15 seconds,
afterwards also the squeegee is lifted
and the suction stops.
NOTE: all these phases are carried
out with the machine operating, so
that the squeegee can dry the clean-
ing 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 procedure BREAK WASHING by
stopping the drive.
2. During the phase of BREAK WASH-
ING, when the accelerator pedal is
released for more than 3 seconds, the
squeegee raises itself and the suction
switches off automatically.
3. After three seconds, the accelerator
can be pressed again, if a machine's
transfer has to be made (you can
make the transfer even if the pedal is
not lifted once the 15 seconds have
passed).
4. Turn the switch key counterclock-
wise to switch off the machine.
ATTENTION:
The mode (BREAK WASHING) is
specic for the transfer at the end of
the cleaning operation.
Re-start the cleaning operation:
A. by pressing the push button (4)
the automatic (AUTO) functioning is
chosen to start working in automatic
mode.
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 re-established
manually.
