2.MACHINE DESCRIPTION
FKC 65 UB is a Scrubber-Dryer machine, driven by an operator seated on board, to
wash and dry hard floors, battery powered, intended for commercial use.
The main systems of the machine are as follows:
▪The detergent solution tank and relevant circuit,
▪The washing brushes plate
▪The dirty water recovery tank and relevant circuit
▪The electrical system and relevant control panel, the steering and speed device.
The function of the detergent solution tank is to store water (with dilution of any
detergent), supplying it to the washing system.
The relevant system includes the tank, filter, proportional valve to adjust flow rate and
controls.
The tank contains the detergent solution (water and detergent) and supplies it to the
washing system when required. The filter protects the solenoid valve from debris
contained into the water. The proportional solenoid valve controls detergent solution
supply to the washing system. The valve automatically prevents the flow of the detergent
solution. The control selector of the solution flow - by controlling opening duration and
section of the solenoid valve - regulates the amount of detergent solution conveyed to
the washing system.
The disc washing device includes: two counter-rotating disc brushes, the electric motor,
the actuator to lift the entire brush unit, the manual cam for lifting the wiper only and the
controls. The brushes wash the floor while the motor and the pair ofgears, solidly attached
to the brushes, actuate their motion. The side band, in bristles, lets the detergent solution
remain in the brushes' working area.
The wiper (or squeegee) is the water collecting device.
The water flow is regulated by a proportional solenoid valve (from 0 to 3.5 litres/minute),
there is also the option of mixing the water with the chemical detergent, contained in the
relevant bottle. The mixture percentage is set by a peristaltic pump which regulates the
detergent flow, conveying it and mixing it downstream of the proportional solenoid valve
(in the version with Ki-Do device).
The function of the recovery device (wiper or squeegee) is to suck the dirty water and
convey it to the recovery tank.
The recovery system includes: the wiper, the vacuum turbine, the filter, the recovery tank
and the controls. The wiper collects the dirty detergent solution from the floor as the
machine moves forward. The vacuum turbine assures the necessary vacuum to suck the
dirty detergent solution from the floor and convey it to the recovery tank. The filter
protects the turbine against the debris and foam. The recovery tank stores the dirty
detergent solution.

The maximum recovery water level is controlled by a level sensor connected to the
control unit and acting on the suction motor; therefore the turbine will stop sucking water
as it reaches the max level in the collection tank.
The function of the control devices and steering wheel (steering and speed devices) is to
control the direction and speed of the machine. The steering control system includes: the
speed pedal, the steering wheel, the brake pedal. The speed pedal is unidirectional.
Depending on the setting of the running direction via the suitable panel selector, the
machine moves forwards or backwards. With the steering wheel the operator steers the
driving wheel in the desired direction.
Both models are equipped with a brake that will stop the machine while moving both
forward and backward. Furthermore, this brake also acts as parking brake, stopping the
rotation of the wheels of the rear axle, each time the machine is turned off or left by the
operator.

4.1Declaration of absence of harmful substances
5We hereby declare that our products, used in the process of assembling the machine, are produced with
materials that comply with the limits established by the regulations in force on the protection of health
and the environment and do not contain substances classified as SVHC (Substance of Very High
Concern) in accordance with CE 1907/2006 regulation (REACH, i.e. Registration, Evaluation,
Authorisation and Restriction of Chemical substances).

6Although the above mentioned substances are not employed in processing cycles of raw materials and
our products, their presence cannot however be ruled out in the order of p.p.m. (parts per million), due
to micro-pollution of raw materials.
4.2Safety devices of fixed closing guards
The components that protect some areas that contain moving parts or live equipment are
considered fixed closing guards.
The brush plate is fitted with fixed closing guard, consisting in the plastic material
protection casing.
The steering column contains moving parts (levers for lifting the brush plate) and live
equipment (electricalpanel, motors wiring). This column is protected by a plastic material
nose, that entirely encloses the head, assembled with screws.
WARNING
Do not remove the fixed closing guards. In the event of maintenance, ensure the same are
reassembled before turning on the machine and starting to work.
4.3Safety devices relevant to mobile guards
There are no mobile guards on the machine.
The battery compartment is housed under the upper dirty water recovery tank. In order to
access it the tank, which is hinged at the top, must be tilted over.
5. CE PLATE POSITION
The technical specifications plate bearing the CE marking is attached on the steering
upright, it is adhesive and must not be removed for any reason.

6. MACHINE TRANSPORT AND LIFTING
Lift the brush plate before proceeding with transport. Place the machine on a pallet, taking
care to lock the wheels to prevent the machine from moving.
Transport and any lifting must be done with the machine on a pallet.
It is recommended to empty the solution recovery tanks.
If the rubber-dryer FKC65 UBis loaded on a vehicle, with ramp, or in anycase every
time it is required to drive it on a steep ramp, it is recommended to lift the brush plate and
take down the splash-guards and brushes.
7. INTENDED USE OF THE MACHINE (washing and drying
phase)
FKC 65 UB is a Scrubber-Dryer machine, driven by an operator seated on board, to
wash and dry hard floors, battery powered, intended for commercial use.
The machinery applies a detergent solution to the hard floor, a solution that is collected
in the solution tank and is conveyed through suitable piping to the brush plate, with
solenoid valve adjustable flow, it scrubs the floor by the combined action of two counter-
rotating brushes and then draws the dirty water into the recovery tank.
It is also possible to spray the floor with water, actuating the brushes only for scrubbing
and cleaning, without drying.
Finally, when a floor is already wet, it might be required to permanently lift the brush
plate without actuating its rotation and pass with activated suction only, in order to suck
the water from the floor and draw it into the recovery tank .
Other operations are not intended for the FKC 65 UB .
Any other operation should therefore be considered as improper.
