1.3. PRODUCT IDENTIFICATION
The nameplate located under the dashboard, above
the battery connector, contains the information.
1.4. SPECIFIC USE
This appliance is suited for the commercial use,
e.g. in hotels, schools, hospitals, factories, shops,
oces, and rental companies.
This machine is a floor scrubber-drier: it must be used
to scrub and to vacuum liquids of flat, rigid, horizon-
tal, smooth or moderately rough and uniform floors
that are free from obstacles in both civic and indu-
strial environments. Any other use is prohibited.
Please refer very carefully to the safety information
reported in this manual.
The scrubber-drier distributes a quantity of a water
and detergent solution (adjustable) on the surface to
be cleaned, while the brushes remove any dirt on the
ground. The machine’s suction system, using a ground
squeegee, perfectly dries the liquids and the dirt just
removed from the front brushes in a single pass.
By efficiently combining a cleaning detergent with
various types of brushes (or abrasive disks), the ma-
chine can adapt to all the various combinations of
floors and dirt.
1.5. TECHNICAL MODIFICATIONS
The manufacturer reserves the right to make techni-
cal modifications to the product, without prior notice,
in order to make the necessary technical upgrades or
improvements. For this reason, some details of your
machine may be different from the information in the
sales catalogues or from the illustrations presented in
this booklet. However, this will not reduce safety or in-
validate the information supplied to this regard.

2.2. NOISE AND VIBRATIONS
See last page.
3. HANDLING INFORMATION
3.1. PACKING LIFTING AND TRANSPORT
During all lifting or transport operations, make
sure that the packed machine is securely anchored
to prevent it from tipping over or falling accidentally.
Transport vehicle loading and unloading operations
must be carried out with adequate lighting.
The packed machine must be handled using ade-
quate devices, making sure not to damage/strike any
part of the packing, not to tip it over and to be very
careful when placing it on the ground.
☞All these instructions also apply to the batteries
and the battery charger.
3.2. CHECKS UPON DELIVERY
☞When the goods are delivered (machine, battery
or battery charger) by the transporter, carefully check
the condition of the packing and its contents. If the
contents have been damaged, notify the transporter
and reserve the right, in writing (select the word “re-
serve” on the document), to submit a claim for com-
pensation before accepting the goods.
3.3. UNPACKING
Wear safety clothing and use adequate tools to
limit the risks of accidents.
Carry out the following steps if the machine is packed
with a cardboard housing:
- Use scissors or clippers to cut and eliminate the pla-
stic straps.
- Slip off the cardboard housing from the top of the
packed machine.
- Remove the envelops inside and check their con-
tents (use and maintenance manual, battery charger
connector)
- Remove the metallic brackets or plastic straps that
secure the machine to the pallet.
- Release the brushes and the squeegee from the pa-
cking.
- Take the machine off the pallet (pushing it
backward) by using an inclined surface that is solidly
attached to the floor and to the pallet.
Take the same precautions and follow the same in-
structions to remove the optional battery charger
from the packing (holding the special handles to ex-
tract it from the top of the packing) and the optional
battery.
After moving the machine away from all the packing,
start mounting the accessories and the batteries as
per the instructions provided in the specific section.
Keep all the pieces of the packing since they might be
useful in the future to protect the machine and the
accessories during transport to another location or to
authorised service centres. If not, the packing can be
disposed in accordance with current disposal laws.
3.4. LIFTING AND TRANSPORT: MACHINE,
BATTERY AND BATTERY CHARGER
Never use a forklift truck to lift the machine. There
are no places on the frame that can be used to lift the
machine directly.
Before preparing the packing and transporting the
machine:
- Empty the recovery tank and the detergent solution
tank.
- Disassemble the squeegee and the brushes or scrapers.
- Disconnect and remove the batteries.
Place the machine on the original pallet (or an equi-
valent one that can bear the weight and is big enou-
gh for the machine’s overall dimensions) using an
inclined surface.
Solidly anchor the machine and the squeegee to the
pallet using metallic brackets or other elements that
can bear the weight of the parts.
Lift the pallet with the machine and load it on the
transport vehicle.
Secure the machine and the pallet using ropes con-
nected to the transport vehicle.
As an alternative, when using private transport vehi-
cles, use inclined ramps to push the machine without
the pallet, making sure to protect all parts and the
machine itself against violent impacts, humidity,
28

vibrations and accidental movements during tran-
sport.
The battery boxes have holes where tools can be ho-
oked for handling.
☞To lift or insert the battery (into the machine
compartment), use only suitable personnel and
equipment (cables, eyehooks, etc.) for the operation
and to bear the weight of the loads involved. When
transporting, take the same precautions and follow
the same instructions provided for the machine toge-
ther with those in the special manufacturer’s manual.
The battery charger can be transported on its sup-
ports, both vertically and horizontally. Take the same
precautions and follow the same instructions provi-
ded for the machine together with those in the spe-
cial manufacturer’s manual.
4. TECHNICAL INFORMATION
4.1. GENERAL DESCRIPTION
4.1.1. MACHINE
We can summarise the machine’s main features as
follows:
- The form of the squeegee, the air flows and the
specially designed rubber blades produce excellent
drying results even on tiled floors. Thanks to the par-
ticular balanced shape of the machine frame and the
squeegee support, no water residues are left behind
in a curve, and even when a smaller squeegee is used.
Excellent distribution of weights and dimensions
thanks also to the heavy weight of the brush plate
and batteries in the centre of the machine.
- A heavy weight on the brushes makes them work
efficiently on the floor. The pressure is generated by
the weight of the plate, without springs or additional
devices that lead to difficulties and inaccuracy. The
entire mass is generated by the hanging weight of a
15 mm steel ship’s plate.
- A large volume of water in the tanks reduces dead
time since fewer trips are needed to collect water and
dump dirt. There is no delicate flexible diaphragm
that, at a technical level, is difficult to clean.
- The dirty water tank leaves several litres for decan-
ting any foam
- Robust construction. The frame and squegee are
made in extra thick plate and aluminium 6 mm, 8 mm,
10 mm up to 20 mm – are laser cut and welded. The
brush plate is made from 15 mm ship’s sheet metal,
with a surface treatment that protects the plate and
the paint for thousands of hours in a saline fog. All
screws are made with stainless steel; the tanks (body)
are made with 7-8 mm thick shockproof polyethyle-
ne. Everything is simple and very strong, without any
other complicated designs.
- The battery compartment can house very large bat-
teries, which guarantees extended running time.
- The suction motor is housed inside the machine,
thus reducing operating noise to a minimum.
- The recovery tank is very easy to clean due to the
lack of the characteristic difficult access points of re-
covery tanks located in a lower position.
4.1.2. BATTERY
Regardless of the type of construction, battery per-
formances are indicated with the term capacity,
which always refers to a discharge period. Another
important value is the number of possible dischar-
ges. The capacity is expressed in amps per hour (Ah),
while the discharge period is generally indicated as
20 hours (C20 or 20h, or not expressly indicated) or
5 hours (C5 or 5h). The discharge/charge cycles indi-
cate the number of times that the battery can hold
a charge under the best conditions, i.e. they indicate
the useful battery service life complying with all the
necessary measures.
Therefore, the capacity of a battery varies depending
on how fast it uses energy (current). That’s why the-
re’s such a variation in the capacity values expres-
sed as C5 or C20. These factors must be taken into
account when comparing products available on the
market with our own.
This machine can be equipped with two types of bat-
teries that differ in terms of their construction and
features.
- Pb-Acid battery with tubular armoured modules:
the electrolyte level in each element must be perio-
dically checked!
If one element is no longer covered by the acid
solution it will oxidise in 24 hours, thus perma-
nently affecting that element’s performance.
Refer to the battery manual to avoid physical da-
mage and economic loss.
- Gel module battery: this type of battery is main-
tenance free and does not require special envi-
ronments for recharging (since it does not emit any
harmful gases); therefore, it is highly recommended.
It should not be taken for granted that batte-
ries and battery chargers with the same technical
features as those we offer will produce the same
results. Only perfect compatibility between the-
se elements (Pb-Acid batteries, gel batteries and
battery chargers) will safeguard the performan-
ces, the service life, the safety and the economic
value invested.
4.1.3. BATTERY CHARGER
This type of high-frequency battery charger efficien-
tly charges batteries, extending their operating and
service life. In addition, because they can be confi-
gured it is a very versatile solution that reduces the
number of chargers required in the warehouse. The
same battery charger can be used for both Pb-Acid
batteries and for gel batteries.
The information indicated on the digital display can
be used to always keep the charging process, the bat-
29

tery and the battery charger under control (read the
specific manual for more details).
It should not be taken for granted that batte-
ries and battery chargers with the same technical
features as those we offer will produce the same
results. Only perfect compatibility between the-
se elements (Pb-Acid batteries, gel batteries and
battery chargers) will safeguard the performan-
ces, the service life, the safety and the economic
value invested.

We recommend to call the assistance centre or a tech-
nician if you have problems with the settings given.
Do not open or tamper the electronic board.
5.3. BATTERY CHARGER CONFIGURATION
The machine is equipped with a battery charger con-
figurated for GEL batteries
To change the battery charger settings read the man-
ual provided by the battery charger manufacturer.
If the machine is supplied with a battery and a
charger, the setting of the machine and the charger
is carried out by the manufacturer.
In the event of changes to the equipment, i.e. the type
of battery and charger, we always recommend that
you contact your authorised service centre both for
the machine setting and the setting of the charger’s
charging curve.
As a general rule, the following criteria apply:
For Pb-acid and GEL batteries:
charging current of approx. 10-12% of the capacity in
Ah-C20
For lithium batteries:
current of approx. 40% of the capacity in Ah
Failure to comply may result in serious damage to
the battery and warranty invalidation.
5.4. MACHINE PREPARATION
Before starting to work, wear non-slip shoes, glo-
ves and any other personal protection device indica-
ted by the supplier of the detergent used or conside-
red necessary based on the operating environment.
☞Do the following before starting to work. Refer to
the relative sections for a detailed description of the-
se steps:
check the battery charge level and charge, if necessary.
Mount the brushes or scraper disks (with the abrasive
disks) that are suitable for the surface and work in-
volved.
Mount the squeegee, check that it is solidly attached
and connected to the suction hose and that the
drying blades are not too worn.
32

Make sure that the recovery tank is empty. If not,
empty it completely.
Check and completely close the detergent solution
release control.
Fill the detergent solution tank with a mix of clean water
and non-foaming detergent in an adequate concentra-
tion through the anterior hole. Leave 2 cm between the
mouth of the plug and the level of the liquid.
☞To avoid risks, become familiar with the machine
movements, carrying out test runs on a large surface
without obstacles.
To obtain the best results in terms of cleaning and
equipment service life, you should do the following
simple but important operations:
- Identify the work area, moving all possible obstacles
out of the way; if the surface is very extensive, work in
contiguous and parallel rectangular areas.
- Choose a straight work trajectory and begin wor-
king from the farthest area to avoid passing over are-
as that have already been cleaned.
6. OPERATING INFORMATION
6.1. BATTERY CHARGING
Prepare and check the battery charge according to
the instructions provided in the specific section.
Detach the battery connector from the machine po-
wer connector (the one with the gripping fins) and
connect the battery connector to the battery charger
connector.
Do not connect the battery charger to the scrub-
ber-drier’s main wiring connector.
Hold the connectors with the hands; do not pull them
using the cables.
If the machine is equipped with Pb-Acid batteries,
charge only in a well-ventilated area, lift the superior
cover and open the battery plugs.
Follow the steps indicated in the battery manufac-
turer’s operating and safety manual (see the battery
maintenance section).
If the machine is equipped with gel batteries (mainte-
nance free), follow the instructions indicated here below.
If the machine is used regularly:
Always keep the batteries connected to the battery
charger when the machine is not being used.
If the machine is not used for extended time periods:
Charge the battery during the night after the last
work period, then disconnect the battery from the
battery charger.
Charge the battery during the night before using the
machine again.
Intermediate or incomplete charging while working
should be avoided.
If the machine is equipped with Pb-Acid batteries,
use a hydrometer to check the element liquid inten-
sity on a regular basis: if one or more elements are
discharged and the others fully charged, the battery
has been damaged and should be replaced or repai-
red (refer to the battery service manual).
Close the element plugs and lower the superior cover.
Hold the connectors with the hands; don’t pull them
using the cables.
Reconnect the machine connectors.
6.2. SQUEEGEE AND SPLASH GUARD
ASSEMBLY, DISASSEMBLY AND
ADJUSTMENT
The squeegee is the main component that ensures
perfect drying.
6.2.1. SQUEEGEE ASSEMBLY
Slightly screw the two knobs ( Photo L - 7 ) into the
squeegee body and insert the squeegee into the
slots situated on the squeegee support.
Screw the two knobs ( Photo L - 7 ) in order to secure
the squeegee to the support.
Firmly insert the suction hose ( Photo L - 1 ) into the
pipe in the squeegee body.
6.2.2. SQUEEGEE DISASSEMBLY
Disconnect the suction hose from the squeegee
body.
Unscrew the two knobs ( Photo L - 7 ) that secure the
squeegee to its support and pull the squeegee to free it.
6.2.3. SQUEEGEE BLADES DISASSEMBLY /
ASSEMBLY
Disassemble the squeegee from its support (see 7.2.2)
Unscrew the knobs ( Photo L - 7 ) ( Photo L - 3 ) placed
on the squeegee body and apply some pressure on
their bolts in order to push out the plastic support of
the squeegee blades from the squeegee body.
Tear o the rubber blades from the plastic support.
Assemble the new blades on the plastic support by
the means of the plastic pins that have to be xed in
the holes placed the blades.
Push the plastic support of the squeegee blades into
the squeegee body and screw the knobs ( Photo L - 7 )
to secure it to the squeegee body.
Reassemble the squeegee to its support (see 7.2.1).
6.2.4. SQUEEGEE ADJUSTMENT
The knob screw on the squeegee support ( Photo L -
2 ) adjusts the squeegee’s inclination with respect to
the oor. The two red knobs on the sides, connected
to the rear wheels of the squeegee ( Photo L - 5 ) are
to adjust the pressure of the squeegee to the oor.
When the squeegee is perfectly adjusted, the rear
squeegee blade, sliding as it moves, bends in all
points forming an angle of 45° with the oor.
As the machine operates (advances), the knobs ( Photo
L - 2 ) ( Photo L - 5 ) can be used to adjust the inclination
and pressure of the squeegee blades on the oor.
Squeegee drying must be uniform along the entire
drying line: damp patches mean that drying is insu-
33

cient; turn the adjustment knobs to optimize drying.
6.2.5. SPLASH GUARD ASSEMBLY/ DISASSEMBLY
The splash guard is assembled to the brush plate with
a spring holder linked to the brush plate itself ( Photo
M - 1 ).
To disassemble the splash guard simply detach the
spring holder and pull the splash guard.
To reassemble, x the splash guard in the brush plate,
and then hook the steel cable to one side of the plate
and the spring holder to the other side of the brush
plate.
6.3. BRUSH ASSEMBLY / DISASSEMBLY
Never use the machine if brushes or scrapers and
abrasive disks are not perfectly installed.
Assembly:
Make sure that the brush plate is raised; otherwise lift
it by following the instructions provided in the spe-
cific section.
Make sure that the ignition key on the control panel
is in position “0”.
Bring the brushes (or the guide disks equipped with
abrasive disks) near the connections, under the brush
plate; lower the washing plate and start the brushes
turning: the brushes/discs couple automatically;
Do not allow the length of the rows of brushes to
become lower than 1 cm.
Do not allow the thickness of the abrasive disks to
become less than 1 cm.
Working with excessively worn brushes or excessi-
vely thin abrasive disks may damage the machine
and the floor.
Regularly check the wear on these parts before star-
ting to work.
Disassembly or replacement:
Make sure that the brush plate is raised; otherwise lift
it by following the instructions provided in the spe-
cific section.
Make sure that the ignition key on the control panel
is in position “0”.
While holding the brushes (or the guide disks) with
the hands under the plate, turn them in the rotation
direction while lowering to release them from the
guide plate.
6.4. FILLING AND DRAINING THE DETERGENT
SOLUTION TANK
☞The temperature of the water or the detergent
should never exceed 50°C.
• Always empty the detergent solution tank before
filling it up.
To fill:
• Remove the plug in the front of the machine .
• Leave 2 cm between the mouth of the plug and the
liquid level. Do not fill beyond this point!
• Add the required quantity of the chemical product,
considering the percentage indicated by the sup-
plier, with reference to the full tank capacity listed on
the product sheet.
• Use only those products suitable for the floor and
the dirt to be removed.
The machine was designed to be used with non-
foaming and biodegradable detergents made speci-
fically for scrubber-driers. The use of other chemical
products (such as sodium hypochlorite, oxidisers,
solvents or hydrocarbons) may damage or destroy
the machine.
• Follow the safety regulations specified in the relati-
ve section and indicated on the detergent container.
• Contact the machine manufacturer to obtain a com-
plete list of available and suitable detergents.
☞Always add the detergent after filling the tank with
water to prevent foam from being created inside.
• Do not leave the water hose unattended and insert
it completely into the tank: the hose might move and
get sensitive parts of the machine wet.
Close the tank with its plug…
To drain:
• Unscrew the cock.
• Close the drainage plug firmly.
6.5. DRAINING THE RECOVERY TANK
The dirty water must be drained in accordance with
national regulations.
The user is completely responsible for ensuring com-
pliance with such rules.
After the detergent solution is finished, always empty
the recovery tank before filling it again.
In general, the recovery tank can be emptied whene-
ver required, and even during intermediate phases of
the work cycle.
The recovery tank volume is higher than the deter-
gent solution volume, therefore a potentially dan-
gerous situation for the suction motor should never
occur. In any case, a safety float turns off the suction
motor if the dirty liquid level is too high.
If water or foam starts leaking from under the
tanks for any reason, immediately turn off the suction
motor and empty the recovery tank.
To drain the tank:
Drive the machine to a suitable location to drain the
dirty water and preferably near a toilet or a sewer
drain (comply with the national regulations for waste
water disposal).
Turn off the machine and remove the key from the
panel.
Detach the drain hose from the hook and, keeping it
high, unscrew the plug.
Lower the drain hose toward the selected drainage
point.
The emptying operation can be interrupted quickly
and whenever required just by raising the drain hose.
Check how much dirt is still in the tank and, if neces-
34

sary, wash it inside through the inspection hole by
unscrewing the rear window .
Fully tighten the drain hose with the screw plug and
hang it on the support behind the machine. The drain
hose plug must be airtight, otherwise the subsequent
pressure loss will reduce drying efficiency.
6.6. DRIVING THE MACHINE
Check connection between the power and battery
connectors, located under the control panel.
Put the ignition key in and turn it.
Check battery charge status via the control unit and,
if sufficient, select the running speed wanted, operate
the brush control key and the suction control key. Now
open the solution cock by lowering the detergent do-
sage lever which is at the back of the machine, lower
the suction unit by lowering the squeegee control le-
vel, lower the washing unit, levering with your foot on
the brush plate control lever.
Move forwards, pulling the forward lever up . Re-
member to lift the floor cleaner before reversing to
avoid damaging it.
6.7. WORK METHOD
6.7.1. PREPARATION AND WARNINGS
Remove any loose solid residue from the surface
to be treated (using suitable tools, such as vacuum
cleaners, sweepers, etc.). It this is not done, the solid
dirt might prevent the squeegee from operating cor-
rectly, reducing drying efficiency.
This machine can driven only by trained personnel.
6.7.2. OPERATING CONTROLS
• Battery charge control: the sequence of lights pro-
gressively turns off until the battery is discharged .
When the red light turns on, turn off the brush motor,
close the solution supply, finish drying the small resi-
dual moisture and go to the battery charging area to
charge the battery.
The batteries may be irreparably damaged if the
residual charge level drops too low (see the battery
operating manual). Do not force the battery dischar-
ge beyond the safety limits, turning the key off and
on or in any other manner.
When an abnormal situation occurs, such as when
the machine doesn’t have enough power and the
safety devices don’t trip, stop immediately: follow
the instructions in the troubleshooting section and
contact a specialised worker to check the discharge
control devices.

Turn the key, remove it from the control panel and
disconnect the battery from the machine wiring.
☞All work on the electrical system as well as all main-
tenance and repair operations (especially those not
explicitly described in this manual) should be carried
out only by authorised service centres or by speciali-
sed technical personnel who are experts in the sector
and in the pertinent safety regulations.
Performing regular maintenance on the machine,
and carefully following the manufacturer’s instruc-
tions, is the best guarantee for obtaining the best
performances and extended machine service life.
7.1. TANKS
Drain the two tanks as described in the relative sec-
tions.
Remove any solid dirt by filling and draining the
tanks until all dirt has been eliminated: use a washing
hose or similar tool to do this.
Water hotter than 50°, a high-pressure cleaner
or excessively powerful sprays may damage the
tanks and the machine.
Leave the plugs of the tanks open (only while the ma-
chine is not being used) so that they can dry and thus
prevent the formation of foul odours.
7.2. SUCTION HOSE
Detach the suction hose from the squeegee.
Now you can wash the hose and remove any obstruc-
tions.
Firmly insert the hose on the squeegee body.
7.3. SQUEEGEE
Do not handle the squeegee with bare hands:
wear gloves and any safety clothing needed to carry
out the operation.
Detach the squeegee from the machine and clean it
under running water using a sponge or a brush.
Check the efficiency and the wear on the strips in
contact with the floor. They are designed to scrape
the film of detergent and water on the floor and to
isolate that portion of the surface to enhance the
vacuum of the suction motor: this ensures that the
machine will dry very efficiently. Working constantly
in this manner tends to round or to deteriorate the
sharp edge of the strip, thus reducing drying efficien-
tly. This is why the squeegee strips must be replaced.
To replace the worn blades, follow the instructions in
the relative section. Turn the blades around to wear
down the other sharp corners or to install new ones.
7.4. ACCESSORIES
Remove and clean the brushes or the scraper disks.
To avoid damaging the floor and the machine, careful-
ly check if foreign matter, such as metallic parts, screws,
chips, cords or similar items, has become jammed.
Check that the brushes are flat as they work on the
surface (check for any irregular wear on the brushes
or on the abrasive disks). If necessary, adjust the slant
of the action on the floor.
Use only the accessories recommended by the manu-
facturer: other products may reduce operating safety.
7.5. MACHINE BODY
Use a sponge or a soft cloth to clean the exterior of
the machine and, if necessary, a soft brush to elimi-
nate tough dirt. The machine’s shockproof surface
is rough to make it harder to see scratches caused
during use. However, this does not make it easier to
remove tough stains on the surface. Steam machines
can be used but it’s prohibited to use hoses with run-
ning water or a high-pressure cleaner.
7.6. BATTERIES
PB-ACID
Carry out maintenance operations in accordance with
the manufacturer’s instructions and with all the other
instructions provided in this manual.
Exposing the element plates (not completely immersed
in the acid solution) will lead to rapid oxidation and irre-
parably reduce the element’s operating capacities.
An overflowing acid solution may corrode the machine.
Use battery chargers recommended by the manufac-
turer and, in any case, those that are suitable for the
type of battery to be charged.
Always charge batteries in well-ventilated rooms:
there is an explosion risk!
The use of gel or maintenance-free batteries is highly
recommended.
GEL
Carry out maintenance operations in accordance
with the manufacturer’s instructions and with all the
other instructions provided in this manual.
Use only those battery chargers recommended by
the manufacturer.
☞If the batteries are not used, in either case, for an
extended period of time, disconnect them and re-
store the charge within the time limits specified for
the type of battery used (generally and as a precau-
tion, no more than 3 months for Pb-acid/GEL/AGM
batteries, 6 months for Li-ion batteries).
The manufacturer accepts no liability for damage to
batteries caused by failure to follow this procedure.
7.7. FUSES AND THERMAL BREAKERS
The machine is equipped with electric protection
devices on the main operating components to avoid
costly malfunctions.
Thermal cutouts are installed to protect the drive mo-
tor wherever foreseen and the brush motor.
When one of these breakers trips automatically, the
disabled function can be reactivated by fully depres-
