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 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:
•detergent tank (fig. A, ref. 1): contains and transports the mixture of clean water and
detergent;
•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 brushes which distribute 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

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.
The squeegees are packed in cardboard boxes without pallet.
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;
• remove the cardboard;
• remove the bags in the battery compartment and check the contents:
- use and maintenance manual, declaration of conformity, guarantee certificate;
- battery bridges with terminals
- connector for battery charger;
• depending on the model, remove the metal brackets or cut the plastic straps fixing the
machine chassis to the pallet;
• using a sloping ramp, push the machine backwards off the pallet;
• unpack the brushes and squeegee;
• clean the outside of the machine in respect of safety regulations;
• once the machine is clear of the packaging, the batteries can be installed (see relevant
paragraph).
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. Batteries
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 overfill (5 mm
max. above the plates).
•gel batteries: this type of battery requires no maintenance.

ENGLISH
10
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.
