2. MACHINE FEATURES AND TECHNICAL DATA

2.1. IDENTIFICATION

The machine is identified by an adhesive plate attached to the protective casing of the steering column,

which contains indelible data regarding “CE” marking.

The plate must never be removed and should always be kept legible. In case of damage,

a duplicate should be ordered. The machine cannot be sold without the plate.

2.2. DESCRIPTION AND COMPONENTS

The BIG 38/48 scrubber-dryer is designed to clean all flat surfaces by washing and then suctioning the waste

water. The scrubber-dryer has a drive system consisting of two gear motors installed on the rear wheels,

powered by a 36V x 450 A/h box battery. The brush system is driven by three 750W gear motors fitted

directly on the brushes and powered in turn by electric accumulators, as are the suction motors.

The machine uses three rotating brushes to clean the floor surfaces, assisted by the action of the water and

detergent. As the machine travels forward, the rear brush (squeegee), in contact with the floor, collects the

water, which is immediately conveyed by suction to the recovery tank.

The dashboard regulates all the machine functions and provides the operator with an LED system that

indicates the remaining battery capacity and any errors detected by the electronic board, which are displayed

as rapid flashes. All the main functions of the machine can be activated through the dashboard. In detail,

these include:

 raising, lowering and switching on the brushes;

 regulating the water delivery flow;

 starting the suction motors;

 lowering/raising the squeegee;

 turning the lights on and off;

 turning on the flashing beacon and the buzzer;

 starting and stopping the machine.

The load-bearing structure of the machine consists of a cold-galvanised or stainless steel chassis, which

prevents oxidation problems that could affect its reliability.

The machine comprises the following main components:

 a cold galvanized or stainless steel chassis;

3. SAFETY

3.1. INTENDED USE

The BIG 38/48 is a floor scrubber-dryer machine designed and built for use in

industrial environments for washing and drying, with waste water removal, of flat

horizontal surfaces or sloping surfaces with gradients not exceeding 12%.

3.2. IMPROPER USE

 machine operation by unauthorised personnel;

 washing uneven and/or bumpy surfaces;

 washing of sloping surfaces;

 washing of surfaces with a gradient exceeding 12%;

 performing U-turns on a slope exceeding 5% and with a speed of over 1 km/h;

 using the machine in environments containing dangerous substances, and

particularly in explosive atmospheres or unsuitable microclimatic conditions;

 cleaning machine surfaces in the presence of flammable substances;

 use of the machine as a means of transport for people or other vehicles;

 modifying or tampering with the protection devices;

 charging the batteries in locations with insufficient ventilation;

 failure of operators to comply with current safety regulations/procedures;

 fitting equipment/devices likely to interfere with machine operation;

 introducing changes or alterations not authorised by FIORENTINI;

 using acid solutions likely to damage the machine;

 failure to comply with the specifications of the use and maintenance manual.

The information labels placed on the machine should be read carefully and should not be

covered for any reason. FIORENTINI shall assume no liability in any case of improper use

of the machine as described above.

3.3. RECOMMENDED EQUIPMENT

The personnel assigned to operating the machine should be specifically trained, particularly in regard to

safety issues; machine operators must have read and understood this manual.

FIORENTINI declines all liability for accidents involving persons or property caused by

unqualified and unauthorised operators.

3.5. SAFETY AND WARNING DEVICES

 Tampering with safety devices, and their removal or deactivation while the machine

is in operation, is strictly prohibited.

 The efficiency of safety and warning devices should be regularly checked (see point

5.1.).

Front brush guards

The BIG 38/48 machine has three nylon bristle brushes that rotate during

normal operation. Access to hazardous areas is prevented by plastic casing

that serves as a guard. The guard can only be removed intentionally. Removal

of a fixing element will obviously cause detachment of the guard from the

machine.

Warning devices

The BIG 38/48 machine is fitted with various warning devices to alert anyone

who happens to be within the working range of the machine:

 a horn-type acoustic signal to alert any persons in the vicinity of the

machine during normal use;

 an acoustic warning signal (buzzer) that sounds whenever the reverse

gear is engaged;

 a signal light with a yellow flashing beacon to indicate that the machine

is in operation.

SAFETY

BIG 38/48

SAFETY PLUG

The BIG 38/48 machine has a safety plug that connects the power supply batteries to the rest of the

machine. The plug is disconnected by pulling on the handle, which brings all machine functions to an

immediate halt. Operators should therefore familiarise themselves with use of the safety plug, as it provides

the most complete prevention and protection system. Use of the emergency plug should therefore be

automatic in situations of real or presumed emergency.

Pull in the case of

emergency

3.6. RESIDUAL RISKS

Starting from the design phase, FIORENTINI has analysed all the possible hazards related to use of the

machine in order to eliminate or at least minimise any risk of injury to machine operators. Warning signs and

indications regarding the accident-prevention systems and procedures to be used have been provided for

machine operators in order to minimise residual risks.

RISK OF CRUSHING

Risk of crushing is present:

 when replacing the front brushes;

 when checking the brushes in the suction motor;

 when adjusting the squeegee;

When replacing the brushes and adjusting the squeegee, the operator must ensure that the ignition

key is not inserted in the dashboard in order to prevent accidental starting of the machine.

This hazard is indicated by pictograms on the brush guards and recovery tank.

RISK OF OVERTURNING

Risk of overturning is present:

during normal use of the machine when the slope limits specified under improper use of the

machine are exceeded and when the machine is used to clean surfaces that are uneven or have

holes and depressions (see 3.2).

SAFETY

BIG 38/48

Do not use the machine to wash surfaces with gradients exceeding 12% or bumpy or

uneven surfaces likely to affect its stability.

FIORENTINI declines all liability for accidents involving persons or property caused by use of

the machine on surfaces that can compromise its stability. The buyer must put suitable signs

in place to inform the user of the state and condition of the surfaces to be cleaned.

3.7. SAFETY SIGNS

These include signs indicating:

HAZARDS

These signs are triangular with black

pictograms on a yellow background

PROHIBITIONS
