TECHNICAL INFORMATION
3.1. General description
This machine is a scrubber drier for sweeping, washing and drying flat, horizontal, smooth
or moderately rough, even and obstacle free floors in civil and industrial premises. It is
available in both battery and cable versions to meet all running time and weight
requirements.
The scrubber drier spreads a solution of water and detergent in the correct concentration
on the floor and then scrubs it to remove the dirt. By carefully choosing the detergent and
brushes (or abrasive disks) from the wide range of accessories available, the machine
can be adapted to a wide range of combinations of types of floor and dirt.
A suction system incorporated in the machine dries the floor after washing by means of
the low pressure generated in the dirty water tank by the suction motor. The squeegee
connected to the tank collects the dirty water.
3.2. Legend
The main parts of the machine are as follows (fig. A):
• the detergent tank (fig. A, ref. 1): contains and transports the mixture of clean water
and detergent;
• the dirty water tank (fig. A, ref. 2): collects the dirty water picked up from the floor after
washing;
• control panel (fig. A, ref. 3);
• head assembly (fig. A, ref. 4): the main element is the brush which distributes the
detergent solution on the floor and remove the dirt;
• squeegee assembly (fig. A, ref. 5): wipes and dries the floor by collecting the water.
3.3. Danger zones
A - Tank assembly: when using certain detergents, danger of irritation for eyes, skin,
mucous membranes and respiratory tract and of asphyxia. Danger represented by
the dirt collected from the environment (germs and chemical substances). Danger of
crushing between the two tanks when the dirty water tank is replaced on top of the
detergent tank.
B - Control panel: danger of short circuit.
C - Bottom of washing head: danger due to brush rotation.
D - Rear wheels: danger of crushing between the wheel and chassis.

Always load/unload lorries in adequately lit areas.
The machine, packaged on a wooden pallet by the Manufacturer, must be loaded using
suitable equipment (see EC Directive 2006/42 and subsequent amendments and/or
additions) onto the transporting vehicle. At destination, it must be unloaded using similar
means.
A fork lift truck must always be used to lift the packaged body of the machine. Handle
with care to avoid knocking or overturning the machine.
5.2. Checks on delivery
When the carrier delivers the machine, make sure the packaging and machine are both
whole and undamaged. If the machine is damaged, make sure the carrier is aware of the
damage and before accepting the goods, reserve the right (in writing) to request
compensation for the damage.
5.3. Unpacking
IMPORTANT
When unpacking the machine, the operator must be provided with the necessary
personal protection devices (gloves, goggles, etc) to limit the risk of accident.
Unpack the machine as follows:
• cut and remove the plastic straps using scissors or nippers;
• open the packaging;
• remove the bags included in the packaging and check the contents:
- guarantee slip;
- use and maintenance manual;
- battery bridges with terminals (battery model only);
- battery charger connector (battery models only);
• remove the machine from the packaging;
• clean the outside of the machine in respect of safety regulations;
• after unpacking the machine, install the batteries (battery models) or connect the
electrical connections (cable models). See relevant sections.
The packaging may be kept as it can be reused to protect the machine if it is moved to
another site or to a repair workshop.
Otherwise it must be disposed off in compliance with current legislation.
5.4. Electrical connections and earth (cable models)
The electrical characteristics of the machine are given on the rating plate. Make sure the
frequency and voltage correspond to those of the mains supply where the machine will be
operated. As far as voltage is concerned, models where the rating plate specifies a
voltage of 230 V can be used with voltages of between 220 V and 240 V. Similarly,
models rated at 115 V can be used at between 110 V and 120 V. The frequency on the
plate must always correspond to the mains voltage.
ENGLISH
10
IMPORTANT
Make sure the mains circuit is suitably earthed and that the sockets (and any
adaptors used) ensure the continuity of the earth conductors.
! DANGER
Failure to observe these instructions could cause possibly serious damage to people
and things and invalidates the guarantee.
5.5. Power supply batteries (battery models)
Two different types of battery may be installed on these machines:
• tubular leak-proof batteries: the electrolyte level must be checked regularly. When
necessary, top up with distilled water until the plates are covered. Do not over fill (5
mm max. above the plates).
• gel batteries: this type of battery requires no maintenance.
The technical characteristics must correspond to those indicated in the paragraph on the
technical specification of the machine. The use of heavier batteries could seriously
jeopardise manoeuvrability and lead to the brush motor overheating. Batteries with a
lower capacity and weight will require charging more frequently.
They must be kept charged, dry and clean and the connections must be tight.
5.5.1. Batteries: preparation
! DANGER
During installation of the batteries or any type of battery maintenance, the operator
must be provided with the necessary personal protection devices (gloves, goggles
overalls, etc) to limit the risk of accident. Keep away from naked flames, avoid
short circuiting the battery poles, avoid sparks and do not smoke.
The batteries are normally supplied filled with acid and ready for use.
If the batteries are dry, before mounting them on the machine, proceed as follows:
• remove the caps and fill all elements with specific sulphuric acid solution until the
plates are entirely covered (this requires at least a couple of passes for each element);
• leave for 4-5 hours to allow the air bubbles to come to the surface and the plates to
absorb the electrolyte;
• make sure the level of electrolyte is still above the plates and if necessary top up with
sulphuric acid solution;
• close the caps;
• mount the batteries on the machine (following the procedure described below).
Before starting up the machine for the first time, charge the batteries as follows.
5.5.2. Batteries: installation and connection
! DANGER
Check that all switches on the control panel are in the "0" (off) position.
Make sure you connect the terminals marked with a "+" to the positive poles of the
battery. Do not check the battery charge by sparking.
Meticulously follow the instructions given below as short circuiting the batteries
could cause them to explode.
• Make sure the dirty water tank is empty and empty if necessary (see relevant
paragraph).
• Lift the dirty water tank (fig. B, ref. 1) off the detergent tank by pulling it upwards,
making sure you have previously removed the suction hose and dirty water tank drain
hose from their housings.
• Place the batteries in the battery compartment.
ENGLISH
11
IMPORTANT
Mount the batteries on the machine using lifting means suitable for their weight.
The positive and negative poles have different diameters.
• Connect the battery wiring and bridge terminals to the battery poles.
Tighten the terminals on the poles and cover with Vaseline.
• Put the dirty water tank back on the detergent tank.
• When using the machine, follow the instructions below.
5.5.3. Batteries: removal
! DANGER
When removing the batteries, the operator must be equipped with suitable personal
protection devices (gloves, goggles, overalls, safety shoes, etc) to reduce the risk
of accidents. Make sure the switches on the control panel are in the "0" position
(off) and the machine is turned off. Keep away from naked flames, do not short
circuit the battery poles, do not cause sparks and do not smoke. Proceed as
follows:
• disconnect the battery wiring and bridge terminals from the battery poles.
• if necessary, remove the devices fixing the battery to the base of the machine.
• lift the batteries from the compartment using suitable lifting equipment.
5.6. Battery charger (battery models)
IMPORTANT
Never allow the batteries to become excessively flat as this could damage them
irreparably.
i INFORMATION
If the machine has an ON-BOARD battery charger (installed by the manufacturer),
no operations are required as it will already be ready for use.
5.6.1. Choosing a battery charger (machines without ON-BOARD battery charger)
Make sure the battery charger is compatible with the batteries to be charged:
− tubular lead batteries: you are recommended to use a 24V - 5A automatic battery
charger. However, you should always consult the battery charger manufacturer and
manual to confirm the choice.
− gel batteries: use a charger specific for this type of battery.
5.6.2. Preparing the battery charger
If you wish to use a battery charger not provided with the machine, you must fit it with the
connector supplied with the machine (see paragraph "Unpacking" in this manual).
To install the connector, proceed as follows:
• remove about 13 mm of protective sheath from the red and black wires of the battery
charger;
• insert the wires into the connector contacts and squeeze them forcefully with suitable
pliers;
• respect the polarity (red wire + black wire –) when inserting the wires into the
connector.
ENGLISH
12
5.7. Lifting and transporting the machine
IMPORTANT
All phases must be performed in an adequately lit room and adopting the safety
measures most appropriate to the situation.
The operator must always use personal protection devices.
To load the machine onto a means of transport, proceed as follows:
• empty the dirty water and detergent tanks;
• place the machine in the packaging, then rest the packaging on a pallet and fix it with
plastic straps;
• lift the pallet (with the machine) using a fork lift truck and load it onto the means of
transport;
• anchor the machine to the means of transport with cables connected to the pallet and
machine itself.

PRACTICAL GUIDE FOR THE OPERATOR
6.1. Controls - Description
With reference to fig. C, the machine has the following controls and indicator lights:
• Power on light (fig. C, ref. 7 - cable model only): green, indicates that the machine's
power cable is connected to the mains.
• Battery charge light (fig. C, ref. 2 - battery models only): 3 LEDs (red, yellow and
green) which indicate the level of battery charge. There may be:
a) red, yellow and green LEDs on: battery voltage >24V;
b) red and yellow LEDs on: battery voltage <24V;
c) red LEDs on: battery voltage <23V;
d) red LED flashing: battery voltage <21.5V, batteries completely flat; after a few
seconds the brush and suction motor shut down;
• Main Switch (fig. C, ref. 3): enables and disables electrical power to all machine
functions (to turn the machine off, hold the button down for at least 4 seconds).
• Brush button with light (fig. C, ref. 4): enables (LED on) and disables (LED off) the
"brush" function. The brush does not start rotating until the brush lever is operated.
• Suction button with light (fig. C, ref. 5): turns the suction motor on (LED on) and off
(LED off) to dry the floor being washed. The light is on when there is power to the
suction motor.
• Detergent button (fig. C, ref. 6): enables (LED on) and disables (LED off) detergent
flow. The detergent does not flow unless the brush is rotating.
• Brush lever (fig. D, ref. 1): enables brush rotation.
• Squeegee lever (fig. D, ref. 2): raises (if lowered) or lowers (if raised) the squeegee.
• Handle regulation lever (fig. D, ref. 3): allows the angle of the handle to be adjusted.
6.2. Mounting and adjusting the squeegee
The squeegee (fig. A, ref. 5) is responsible for the first phase of drying.
To mount the squeegee on the machine, proceed as follows:
1) check that the squeegee mount (fig. E, ref. 1) is lowered, otherwise lower it by means
of the squeegee lever (fig. D, ref. 2);
2) rotate the machine backwards and rest the handle on the floor;
3) insert the two threaded pins on the squeegee into the slots on the support (fig. E, ref.
1);
4) fix the squeegee by tightening the two knobs (fig. E, ref. 2);
ENGLISH
13
5) insert the sleeve of the suction hose (fig. E, ref. 4) fully into the squeegee;
The squeegee blades scrape the film of water and detergent from the floor and prepare
the way for perfect drying. With time, the constant rubbing makes the edge of the blade
in contact with the floor rounded and cracked, reducing the drying efficiency and requiring
it to be replaced. The state of wear should be checked frequently.
For perfect drying, the squeegee must be adjusted in such a way that the edge of the rear
blade bends during operation by about 45° with resp ect to the floor at every point. Adjust
the height of the blade during operation by regulating the height of the wheels positioned
behind and alongside the squeegee (fig. E ref. 3).
6.3. Moving the machine when not in operation
To move the machine, proceed as follows:
• lift the squeegee using the squeegee lever (fig. D, ref. 2);
• raise the front of the machine by levering on the handle and move it to the destination.
• on arrival, lower the front of the machine.
6.4. Mounting and changing the brush/drive disks
IMPORTANT
Never work without the brushes and drive disks correctly installed.
Brush attachment: turn the machine on by pressing the main switch (fig. C, ref. 3) (LED
on), then press the brush button (fig. C, ref. 4 (LED on). Rest the brush on the floor in
front of the machine. Raise the front of the machine by levering on the handle, then lower
it onto the brush, centring it with the brush cover. Operate the brush lever (fig. D, ref. 1)
repeatedly until the brush automatically engages on the flange hub. If the manoeuvre is
not successful, press on the handle again and repeat the centring and repeated operation
of the brush lever.
Brush release: turn the machine on by pressing the main switch (fig. C, ref. 3) (LED on),
then press the brush button (fig. C, ref. 4 (LED on).
Raise the front of the machine by levering on the handle, then operate the brush lever
(fig. D, ref. 1) repeatedly. After a few pulses, the brush (or drive disk) is released and
falls to the ground.
6.5. Detergents - Instructions
IMPORTANT
Always dilute the detergent according to the manufacturer's instructions. Do not
use sodium hypochlorite (bleach) or other oxidants, particularly in strong
concentrations. Do not use solvents or hydrocarbons. The temperature of the
water and detergent must not exceed the maximum indicated in the technical
specification. They must be free of sand and/or other impurities.
The machine has been designed for use with low-foam biodegradable detergents made
specifically for scrubber driers.
For a complete and up-to-date list of the detergents and chemicals available, contact the
Manufacturer.
Use products suitable for the floor and dirt to be removed only.
Follow the safety regulations on use of detergents given in the section "Safety
regulations".
ENGLISH
14
6.6. Preparing the machine for work
IMPORTANT
Before starting work, wear overalls, ear protectors, non-slip waterproof shoes,
mask to protect the respiratory tract, gloves and all other personal protection
devices recommended by the supplier of the detergent used or necessitated by the
work environment.
Before starting work, proceed as follows:
• Battery models: check the battery charge (charge if necessary);
• make sure the dirty water tank (fig. A, ref. 2) is empty. If necessary, empty it;
• via the opening at the front, fill the detergent tank (fig. A, ref. 8) with a suitable
concentration of clean water and low-foam detergent. Leave at least 5 cm between the
surface of the liquid and the opening of the tank;
• mount the most suitable brushes or drive disks for the floor and work to be performed
(see paragraph 3.4);
• make sure the squeegee (fig. A, ref. 5) is firmly attached and connected to the suction
hose (fig. E, ref. 4). Make sure the back blade is not worn.
i INFORMATION
If you are using the machine for the first time, we recommend trying it on a large
obstacle-free surface first to acquire the necessary familiarity.
Always empty the dirty water tank before filling the detergent tank again.
For effective cleaning and to extend the working life of the machine, follow a few simple
rules:
• prepare the work area by removing all possible obstacles;
• begin working from the furthermost point to avoid walking on the area you have just
cleaned;
• choose the straightest possible working routes;
• divide large floors into parallel rectangular sections.
If necessary, finish off by passing a mop or rag rapidly over parts inaccessible to the
scrubber drier.
6.7. Working

6.8. Some useful tips to get the most from your scrubber drier
•
In the event of particularly stubborn dirt on the floor, washing and drying can be
performed in two separate operations.
6.8.1. Prewashing with brushes or pads
• press the main switch (fig. C, ref. 3) (LED on);
• press the brush button (fig. C, ref. 4) (LED on);
• press the suction button (fig. C, ref. 5) (LED off) to turn suction off;
• operate the brush lever (fig. D, ref. 1) to enable brush rotation;
• make sure the suction motor is off and the squeegee is raised;
• begin washing.
• adjust the flow of detergent to the brush by means of the detergent tap (fig. G, ref. 2).
Flow speed must be regulated according to the operator's chosen advance speed.
The slower the machine moves forwards, the less water is needed.
Persist when washing particularly dirty points to give the detergent time to perform its
chemical action detaching and suspending the dirt and the brushes time to exert an
effective mechanical action.
6.8.2. Drying
Lower the squeegee and with the suction motor on, pass over the same area washed
previously. The result is equivalent to in-depth washing and subsequent ordinary
maintenance will take less time.
To wash and dry at the same time, operate the brush, detergent flow, squeegee and
suction motor simultaneously.
6.9. Draining the dirty water
! DANGER
Use suitable personal protection devices.
Drain the water with the machine disconnected from the power supply.
The dirty water tank drain hose is at the back of the machine on the right.
To empty the tank:
• move the machine near a drain;
• detach the drain hose (fig. A, ref. 7) from its seat by holding it near the fixing spring and
pulling horizontally;
• keeping the end of the hose as high as possible and remove the cap;
• lower the end of the hose gradually, controlling the intensity of the flow of water by
adjusting the height from the ground;
• check the amount of dirt left in the dirty water tank and if necessary wash it out;
ENGLISH
16
• close the drain hose with the cap. Check that it is tightly closed and replace the hose in
its housing.
• You are then ready to wash and dry again.
6.10. Draining the clean water
! DANGER
Use suitable personal protection devices.
Drain the water with the machine disconnected from the power supply.
To empty the tank:
• move the machine near a drain;
• remove the cap (fig. G, ref. 1);
• when the detergent tank is completely empty, replace the cap (fig. G, ref. 1).
i INFORMATION
The water and detergent solution can also be used to wash the dirty water tank.
7.
PERIODS OF INACTIVITY
If the machine is not used for some time, remove the squeegee and brush (or drive disk),
wash them and put them away in a dry place (preferably in a bag or wrapped in plastic
film) away from dust.
Make sure the tanks are completely empty and perfectly clean.
Disconnect the machine from the power supply (depending on the model, unplug from the
mains or disconnect the connector from the battery wiring).
Battery models: charge the batteries completely before storing them. During long
periods of inactivity, you should charge the batteries regularly (at least once every two
months) to keep them constantly at maximum charge.
IMPORTANT
If you do not charge the batteries regularly, they may be irrevocably damaged.
8.
BATTERY MAINTENANCE AND CHARGING
! DANGER
Do not check the batteries by sparking.
The batteries give off flammable fumes. Put out all fires and hot embers before
checking or topping up the batteries.
Perform the operations described above in a ventilated room.
To avoid permanent damage to the batteries, do not run them down completely.
Remember that when the corresponding red light (fig. C, ref. 2) flashes on the control
panel, you must charge the batteries.
8.1. Charging procedure
• if the machine does not have an on-board charger, connect the external battery charger
connector to the battery wiring connector.
• if the machine has an on-board battery charger, connect the on-board battery charger
power cable (fig. H, ref. 1).
ENGLISH
17
IMPORTANT
In the case of gel batteries, use a charger specific for gel batteries only.
• Charge the batteries as described in the battery charger manual;
• at the end of charging, disconnect the connectors;
• reconnect the battery wiring connector to the machine connector (machine with external
battery charger).
9.
MAINTENANCE INSTRUCTIONS
! DANGER
Never perform any maintenance operations without first unplugging the machine
from the mains (cable version) or disconnecting the batteries.
In cable models, the operator must be able to verify from any position that the
machine remains unplugged from the mains socket while maintenance is being
carried out.
Maintenance on the electrical circuit and all other operations not explicitly
described in this manual must be performed by specialised personnel only, in
compliance with current safety legislation and as described in the maintenance
manual.
9.1. Maintenance - General rules
Performing regular maintenance according to the Manufacturer's instructions improves
performance and extends the working life of the machine.
When cleaning the machine, respect the following:
• avoid the use of high pressure washers. Water could penetrate the electrical
compartment or motors leading to damage or the risk of short circuit;
• do not use steam to avoid the heat warping plastic parts;
• do not use hydrocarbons or solvents as they could damage the cowling and rubber
parts.
9.2. Routine maintenance
9.2.1 Float switch: cleaning
• Remove the dirty water tank cap and clean the float switch (fig. I, ref. 1). Make sure it
runs freely on the pin.
• clean the detergent tank filter (CT30 ONLY) (fig. N).
9.2.2 Squeegee blades: replacing
The squeegee blades collect the film of water and detergent from the floor and prepare
the way for perfect drying. With time, the constant rubbing makes the edge of the blade
in contact with the floor rounded and cracked, reducing the drying efficiency and requiring
it to be replaced.
Turning or replacing the blades:
• lower the squeegee by means of the squeegee lever (fig. D, ref. 2);
• tip the machine backwards and rest the handle on the floor.
• remove the suction hose sleeve (fig. E, ref. 4) from the squeegee;
• remove the squeegee (fig. E ref. 1) from its mount by completely unscrewing the two
knobs (fig. E ref. 2)
• remove the blade retainers and blades by unscrewing the knobs (fig. E, ref. 5);
• reuse the same blade by reversing the edge in contact with the floor until both edges
are worn out, or replace with a new blade, fitting it onto the screws on the body of the
squeegee;
ENGLISH
18
• replace the two blade retainers and the blades and screw up the knobs unscrewed
previously.
• Replace the squeegee in its support following the instructions in paragraph 6.2.
9.2.3 Fuses: replacement (battery models) (Fig. L)
The fuse protecting the electrical circuit is located on the battery bridge.
To replace it:
• make sure the dirty water tank is empty and empty if necessary;
• lift the dirty water tank to access the batteries;
• lift the fuse holder lid and remove the fuse;
• fit a new fuse and close the fuse holder cover.
• lower the dirty water tank.
Fuse table: for the complete fuse table, see the spare parts catalogue.
9.2.4 Fuses: replacement (cable models) (fig. M)
The fuses protecting the electrical components are on the electrical components box.
To replace:
• make sure the dirty water tank is empty and empty if necessary;
• lift the dirty water tank to access the electrical components compartment;
• open the cover of the fuse holder on the electrical components box and remove the
fuse;
• fit a new fuse and close the fuse holder cover.
• lower the dirty water tank.
Fuse table: for the complete fuse table, see the spare parts catalogue.
IMPORTANT
Never use a fuse with a higher amperage than specified.
If a fuse continues to blow, the fault in the wiring, boards (if present) or motors must be
identified and repaired. Have the machine checked by qualified personnel.
9.3. Routine maintenance
9.3.1. Daily operations
After each day's work, proceed as follows:
• disconnect the machine from the power supply;
• empty the dirty water tank and clean if necessary;
• clean the squeegee blades and check for wear. If necessary, replace.
• check that the suction hole in the squeegee is not blocked, if necessary remove
encrusted dirt;
• Battery model: charge the batteries according to the procedure described;
9.3.2. Weekly operations
• clean the dirty water tank float switch and make sure it is working correctly;
• clean the suction hose;
• clean the dirty water tank and detergent tank;

The battery discharges too fast
during use, even though it has
been charged correctly and
when tested with a hydrometer
at the end of recharging, it
turned out to be uniformly
charged (battery models only)
• the battery is new and does not
deliver 100% of its expected
capacity
• the battery must be "run-in"
by performing 20-30 charges
and discharges to obtain
maximum performance
• the machine is being used at
maximum capacity for
continuous periods and the
working time is not sufficient
• if possible, use batteries with
a higher capacity or replace
the batteries with others
charged previously
• the electrolyte has evaporated
and does not cover the plates
completely
• top up all elements with
distilled water until the plates
are covered then charge the
battery
The battery discharges too fast
during use, recharging with an
electronic battery charger is
too fast and after recharging
the battery supplies the right
voltage (about 2.14V for each
element without load), but
when tested with a hydrometer
is found not to be uniformly
charged (battery models only)
• the battery supplied filled with
acid by the Manufacturer has
been stored for too long before
being charged and used for the
first time
• if recharging with a normal
battery charger is not
effective, you must use a
double recharging cycle:
- charge it slowly over a 10
hour period at a current of
1/10 the nominal capacity for
5 hours (e.g. for a 100Ah(5)
battery the current must be
set at 10A, using a manual
battery charger);
- rest for one hour;
- charge it with the normal
battery charger.
At the end of charging with the
electronic battery charger, the
battery does not provide the
correct voltage (about 2.14 V
per element without load) and
appears to be uniformly not
charged when tested with a
hydrometer (battery models
only)
• The battery has not been
connected to the battery charger
(for example, because the low
voltage connector of the battery
charger has been erroneously
connected to the machine
connector)
• connect the battery charger
to the battery connector
• the battery charger and power
socket to which the battery is
connected are not compatible
• check that the power supply
characteristics indicated on
the battery charger rating
plate comply with those of the
mains power supply
• the battery charger has not
been installed correctly
• taking the actual voltage
available at the socket into
account, make sure that the
connections of the primary of
the transformer inside the
battery charger are correct
(consult the battery charger
manual)
• the battery charger is not
working
• make sure there is voltage to
the battery charger, that the
