3. 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.
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 discs) 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 cleaning product;
•the dirty water tank (fig. A, ref. 2): collects the dirty water picked up from the floor while
washing;
•the head assembly (fig. A, ref. 3): the main element is the brush which distributes the
detergent solution on the floor and removes the dirt;
•the squeegee assembly (fig. A, ref. 4): 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 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.

5.4. Batteries
Two different types of battery may be installed on these machines:
•wet 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).
•AGM-gel batteries: this type of battery requires no maintenance.
The technical characteristics must correspond to those indicated in the section 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 recharging more frequently.
They must be kept charged, dry and clean and the connections must be tight.
5.4.1. Batteries: preparation
!DANGER
While installing or performing maintenance on the batteries, the operator must be
provided with the necessary personal protection devices (gloves, goggles, overalls,

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. Follow the
instructions in the relevant section.

6. PRACTICAL GUIDE FOR THE OPERATOR
6.1. Controls - Description
The machine has the following controls and indicator lights:
•Brush switch (fig. L, ref. 1): enables/disables head/brush operation.
•Suction switch (fig. L, ref. 2): enables/disables operation of the suction motor.
•Brush lever (fig. A, ref. 5): enables/disables head/brush operation.
•Indicator light (battery version) (fig. L, ref. 3): displays battery charge via a colour
code:
green LED on, battery charged
green LED flashing, battery almost flat
red LED on battery flat
red LED flashing battery flat, machine shut down.
red and green LEDs flashing,over voltage, machine shut down.
•Indicator light (cable version) (fig. L, ref. 3): the LED comes on to indicate that the
machine is connected to the mains power supply.
6.2. Mounting and adjusting the squeegee
The squeegee (fig. G, ref. 1) is largely responsible for drying the floor.

ENGLISH
12
To mount the squeegee on the machine, proceed as follows:
1) slacken the two knobs (fig. G, ref. 3) at the centre of the squeegee;
2) insert the two threaded pins into the slots on the support (fig. G);
3) fix the squeegee by tightening the two knobs (fig. G, ref. 3).
4) insert the suction hose coupling (fig. G, ref. 2) 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 respect to the floor at every point. Adjust
the angle of the blades during operation by regulating the height of the two wheels
positioned behind the squeegee.
6.3. Mounting and changing the brush/abrasive disks
IMPORTANT
Never work without the brushes and drive disks perfectly installed.
Mounting the brush: Turn all machine functions on, raise the head by levering on the
handle. Rest the brush on the floor in front of the machine and centre it with the guard.
Lower the head by levering on the handle and action the brush lever (fig. A, ref. 5)
repeatedly. The brush/es fit/s automatically onto the flange hub. If the manoeuvre is not
successful, press on the handle again and repeat the centring and repeated actioning of
the brush/drive lever.
Using the abrasive disks: mount the abrasive disk on the drive disk then perform the
manoeuvres described for mounting the brush/es on the scrubber driver.
Removing the brush (or drive disk) proceed as follows:
raise the head by levering with the handle and action the brush lever (fig. A, ref. 5)
repeatedly. After a few pulses, the brush/es (or drive disk) is released and falls to the
ground.
6.4. 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".
6.5. 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

ENGLISH
13
devices recommended by the supplier of the detergent used or necessitated by the
work environment.
Before starting work, proceed as follows:
•check the battery charge level (recharge if necessary);
•make sure the dirty water tank (fig. A, ref. 2) is empty. If necessary, empty it;
•through the opening with filter, fill the detergent tank (fig. A, ref. 1) with a suitable
concentration of clean water and low-foam detergent.
•mount the most suitable brush or abrasive disk for the floor and work to be
performed (see the section "Mounting and changing the brush/abrasive disks).
•make sure the squeegee (fig. A, ref. 4) is firmly attached and connected to the
suction hose coupling (fig. G, ref. 2). Make sure the back blade is not worn (see
the section "Mounting and adjusting the squeegee").
•Open the tap to allow the detergent to flow to the brush (fig. C, ref. 1).
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.
6.6. Working
Starting up:
Prepare the machine as described above.
When starting up the machine, follow the sequence below precisely:
1. take the machine to the work area with the head raised (once the head has been
raised to a certain height using the handle, the machine has a system which keeps
it in the raised position). To lower the head, first raise it using the handle. This
releases it and it can then be lowered to the work position.
2. press the brush switch (fig. L, ref. 3)
3. press the suction switch (fig. L, ref. 2)
4. lower the squeegee
5. use the brush lever (fig. A, ref. 5)
When the brush switch is in the "1" position and the brush lever is pulled, the motor which
turns the brush and moves the machine starts up. A special mechanical drive device
uses the friction between the brush and floor to generate a forward movement. When the
mechanical drive lever is released, the brush motor shuts down and the machine stops.
If the machine pulls to one side, restore a straight course by using the direction regulation
knob (fig. M, ref. 1).

The level of electrolyte is low Add distilled water, topping up each
element according to the
instructions
The battery charger does not work
or is not adequate See the battery charger instructions
as long as usual
There are considerable differences
in density between the various
elements of the battery
Replace the damaged battery
The battery is new and does not
provide 100% of the expected
performance
The battery must be run in by
performing 20-30 complete
charging and running down cycles
to obtain the maximum
performance
The machine is used for the
maximum of its power for
continuous periods and the run time
is insufficient
When permitted and possible, use
batteries with a higher capacity or
replace the batteries with others
already charged
The battery runs down too
rapidly during use, even
though it has been charged
with the correct procedure
and at the end of charging
it is evenly charged when
tested by a hydrometer.
The electrolyte has evaporated and
does not completely cover the
plates
Add distilled water, topping up each
element until it covers the plates
then recharge the battery
The battery runs down too
rapidly during use,
charging with the
electronic battery charger
is too fast and at the end
the battery provides the
correct voltage (about 2.14
V per element without
load), but appears to be
uniformly not charged
when tested with a
hydrometer
The battery supplied by the
manufacturer already filled with acid
has been stored too long before
being charged and used for the first
time
If recharging with the normal
battery charger is not effective,
perform a double charge:
- 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.
The battery has not been connected
to the battery charger (for example,
because the low voltage battery
charger connector has been
incorrectly connected to the
machine connector)
Connect the battery charger to the
battery connector
The battery charger and socket to
which it is connected are not
compatible.
Make sure the characteristics of the
power supply shown on the battery
charger rating plate are the same
as those of the mains electricity
supply.
The battery charger has not been
correctly installed Taking into account the actual voltage available at the power
socket, make sure that the
connections of the primary of the
transformer inside the battery
charger are correct (consult the
battery charger manual)
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
The battery charger does not work Make sure there is voltage to the
battery charger, that the fuses are
not blown and that the current
reaches the battery; try charging
with another rectifier. If the battery
charger is not working, contact the
technical service centre and
indicate the serial number of the
battery charger
At the end of charging with
the electronic battery
charger, the battery does
not provide the correct
