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;

3.5. 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
These signs are round with black pictograms
