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 collection 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. B):
• detergent solution tank (fig. B, ref. 1): contains and transports the mixture of clean
water and cleaning product;
• collection tank (fig. B, ref. 2): collects the dirty water picked up from the floor after
washing;
• control panel (fig. B, ref. 3);
• head assembly (fig. B, ref. 4): the main element is the brushes (fig. B, ref. 5) which
distribute the detergent solution on the floor and remove the dirt;
• squeegee assembly (fig. B, ref. 6): wipes and dries the floor by collecting the water.
• concentrated detergent tanks (OPTIONAL) (fig. C, ref. 1)
• battery compartment (fig. C, ref. 2)
• battery charger (OPTIONAL) (fig. C, ref. 3)
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

PRACTICAL GUIDE FOR THE OPERATOR
6.1. Controls - Description
With reference to fig. A, the machine has the follow controls and indicator lights:
• Power light (fig. A, ref. 5): consists of 4 LEDs indicating the battery charge level (see
paragraph 6.7)
• Main Switch (fig. A, ref. 1): enables and disables the electrical power supply to all
machine functions.
• Emergency button (fig. A, ref. 10): acts as a safety device.
• Speed potentiometer (fig. A, ref. 13): regulates the speed of the machine forwards
and backwards
• Solution flow regulation button (fig. A, ref. 3): there are four operating modes
a) STANDARD
b) AUTOMATIC
c) ECONOMY.
d) CHEM-DOSE
• Solution/concentrated detergent flow quantity variation buttons (fig. A, ref. 2):
vary the flow of solution/concentrated detergent
• Display (fig. A, ref. 6):
a) displays the quantity of concentrated detergent when enabled.
b) displays alarm codes.
c) displays hour counter.
• Horn button (fig. A, ref. 12):
• Suction button (fig. A, ref. 9): enables/disables the suction function
• Brush button (fig. A, ref. 8): enables/disables operation of the head.
• Solution tank level indicator: (fig. A, ref. 14): when there is not enough water in the
solution tank, the LED comes on and the head and solenoid valve are turned off
(OPTIONAL)
• Collection tank level indicator (fig. A, ref. 11): when the collection tank is full, the
LED comes on and after a few seconds the suction motor is turned off.
• Head pressure variation buttons (fig. A, ref. 7): vary the pressure of the brushes on
the floor
• Motor drive board indicator (fig. A, ref. 15): indicates the status of the motor drive
board (see section: “Motor drive alarm board”).
6.2. Mounting and adjusting the squeegee
The squeegee (fig. B, ref. 6) is responsible for the first phase of drying.
To mount the squeegee on the machine, proceed as follows:
1) insert the sleeve of the suction hose (fig. E, ref. 1) fully into the squeegee;
2) slacken the two knobs (fig. E, ref. 2) at the centre of the squeegee;
3) insert the two threaded pins into the slots on the support (fig. E, ref. 3)
4) fix the squeegee by tightening the two knobs (fig. E, ref. 2)
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 angle of the blade during operation by regulating the height of the two wheels
positioned behind the squeegee.

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 water cleaners. 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 Suction motor air filter and float: cleaning

10.3. Motor drive alarm board
The board controlling the motor drive is located inside the front upright
(fig. C ref. 6).
If drive is
interrupted, the error code should be identified by means of the status LED. In the absence of
malfunctions, the status LED is steadily on while the machine is in operation. If a malfunction is
detected, the status LED provides two types of information, a slow flash (2 Hz) or a rapid flash (4
Hz) to indicate the severity of the malfunction.
Malfunctions with a slow flash are cancelled automatically once the malfunction has been repaired
and the machine functions normally again. Malfunctions with a rapid flash ("*" in the table) are
considered more serious. The machine must be turned of using the key switch
(fig. A ref. 1)
to
reset operation after repairing the malfunction.
The indication of severity remains active for 10 seconds, after which the status LED flashes
constantly showing a two digit malfunction code until the repairs have been carried out.
