DIAGNOSTICS

9
When the control detects an abnormal situation it stops and gives an error. The type of error can be determined from the
LED diagnostics. There are two types of error: serious and non-serious.
Non-serious errors
Recognised by an LED flashing quickly.
Resolve the error situation by putting the start controls into neutral and bringing the potentiometer to minimum.
There are two types:
- At least one potentiometer is not at 0.
- Forward and reverse start controls are active simultaneously.
Serious errors
Recognised by counting the number of consecutive flashes given by the LED.
Resolve the error situation by switching off the control with the key.

choosing the detergent
Select the right detergent to clean the floor properly as an excessively aggressive one may be
harmful. Use low foam detergent or an anti-foam additive to avoid damaging the vacuum motor. If
these products are not available, pour 50 cc of common wine vinegar in the recovery tank before
washing, to prevent foam from forming.
machine preparation and start-up
Before using the scrubbing machine check:
Turn the main key switch to start the machine
fill with water
press the pedal on the right to move the vehicle forward or backwards depending on the gear
selector position (fig. 6)
stop the engine by turning the key left, to position "2".
ways to use
The washing operation is very delicate as, based on experience, the type of brush to use, the need or
otherwise of a dual washing action, and the good choice of detergent, must be judged correctly. If
the floor is extremely dirty we recommend the dual washing action. In this initial phase the
squeegee is lifted and the brushes are in the work position. A first pass is given to the surface of a
few tens of square metres when the brushes are started. The detergent is left on the floor to dissolve
the dirt, working as solvent until taken up by the second pass. The second washing action takes
place with the brushes lowered and the squeegee touching the floor.
To perform the washing operation, press the switch to lower the brushes and the motors will start
automatically.
The dosage lever for the detergent water must be activated immediately.
If the dual washing action is not performed, lower the squeegee by putting the switch into position 1
(stable). The vacuum motors automatically start when the squeegee lowers and switch-off when it
lifts. Once the washing and drying operation is completed, turn off the water using the lever and
then lift the brushes using the switch. Finally lift the squeegee by putting the switch into position
"0". Please note that the squeegee automatically lifts when reversing.

14
adjusting the squeegee
The squeegee must be correctly adjusted (fig. 8) to guarantee perfect cleaning.
This type of squeegee is excellent at collecting water and channelling it towards the vacuum pipe,
but is very sensitive and must be parallel with to parallelism with the ground. To adjust the
squeegee:
Remove the key from the dashboard to avoid any accidental ignition
loosen the upper screws if the blades are pressed into the wings and tighten the lower screws
perform the operation in reverse if the blades are pressed on the centre
adjust the pressure by means of the ring nut: tighten to increase pressure on the ground and
loosen to decrease it.
The correct pressure is obtained when the edge of the blade touches the floor with a 60°
inclination, -40° respect to the ground.
Fig. 8
replacing the brushes
To replace the brushes (fig. 9):
Remove the key from the dashboard to avoid accidental ignition
Loosen the knobs and remove the brush cover guard
Turn each brush until its knob is accessible, press the knob and remove the brush which will fall
to the ground
To insert a new brush:
Place the hexagon of the female joint on the male joint on the motor
Lift the brush vertically, turning it until it automatically fits in.
Insert the guards and tighten the knobs

SAFETY, MAINTENANCE AND CHECKS
MAIN SAFETY STANDARDS
The following standards must be strictly complied with to avoid injury to the operator and damage
to the machine.
Carefully read the labels on the machine and do not cover them
Do not mix different types of detergent to avoid the production of harmful gases
Do not use the machine in an explosive atmosphere
Do not use the machine as means of transport
Do not use acid solutions that could damage the machine
Do not vacuum flammable liquids
Use a powder extinguisher in case of fire. Do not use water.
Should anomalies be detected in the machine's operation, make sure they are not caused by a
lack of routine maintenance. If not caused by a lack of maintenance, request the intervention of
the FIORENTINI after-sales assistance centre.
The fixed and movable protection systems must always be in their housings; it is compulsory to
restore them before restarting the machine.
Do not wash the machine with compressed water jets or corrosive substances
Do not dump the machine when scrapping it. It contains materials subject to regulations
covering their recycling or disposal at authorised sites only
The machine does not cause damaging vibrations
The flashing light must be constantly on and working when the key switch is activated. The
switch on the dashboard must
only be placed in position "0" in particular situations and with the machine stationary.
Always keep the machine at a safe distance from the edge of the pavement and large unevenness
in the floor
Make sure no unauthorised people approach the machine
Do not operate the machine if it is stationary for special interventions
Do not make turns at excessive speed, particularly if the floor is not level
It is strictly forbidden to touch the bottom part of the machine with your hands when a

batteries
What to do with the batteries:
Leave the battery cover open during charge
Never use naked flames or smoke near the batteries
Be careful with the liquid because it is corrosive
Do not create sparks near the batteries
The battery gases are explosive
Do not reverse the polarity
CHECKING THE BATTERIES CHARGE STATUS
This type of check is shown on display.
Charge when the electrolyte density is 1.260 (30° Bè) at 30°C with the electrolyte at the right
level, between 100% and 75% on display
Partially discharged if the density is between 1.26 (30° Bè) and 1.20 ( 24° Bè), between 50%
and 25% on display
Fully discharged if the density is below 1.14 (18° Bè), below 25% on display
DENSITY MEASUREMENT
This check of the battery charge status is done with the hydrometer, when the batteries are charging.
1. Insert the hydrometer syringe and withdraw a sufficient amount of electrolyte to bring up the
float
2. Make sure its top does not touch the rubber ball or it remains attached to the glass walls.
3. To measure the density after distilled water has been added, wait for the density
to equalise throughout the liquid contained in the element

17
WATER TOP-UP
1. Add distilled water to each battery cell after having charged the batteries, to bring the liquid
level to 6 mm above the plates.
2. Repeat this operation every time the level drops, but never going beyond one week between
one top-up and the next.
LIMITS OF CHARGE
Do not recharge the battery if the density has not dropped below 1.24 (28 Bè) at the end of the
working day.
The recommended maximum temperature is 45°. If the electrolyte temperature increases by more
than 10/12°C with respect to the ambient temperature, an overload is possible regardless of the
effectively reached temperature.
ROOMS TO CHARGE THE BATTERIES
The gases developing during charge present dangers of explosion, therefore make sure the rooms
are well ventilated and the temperature does not exceed 40/45°C.
If ventilation through the windows is not sufficient, provide special exhaust ducts which must not,
however, flow into the flues. When a change is required, this must be as quick as possible using
suitable fans.
BATTERIES NOT IN CONTINUOUS SERVICE OR INACTIVE
The batteries spontaneously discharge (self-discharge) during periods of inactivity.
If the battery is not continuously used:
1. Monthly charge it with a current intensity indicated as "final" until a vivacious development of
gas is noticed in all elements and until the voltage and specific gravity readings remain constant
for 3-4 hours
2. This must be done even if the specific gravity measurements are high. The battery must be kept
in a dry place if it is inactive for long periods

DISPOSING OF THE BATTERIES
Batteries are considered "toxic-noxious" waste.
To dispose of them, they must only be given to assigned collectors who have authorisation and who
show this authorisation upon request. In case of impediment, the "temporary storage" must comply
with current laws, and mainly:
Be in possession of the temporary storage authorisation
Store in sealed plastic containers with a capacity of not less than the volume of the electrolyte
contained in the batteries or, however, in such a manner that rainwater cannot penetrate the
container
replacing the squeegee blades
The squeegee blades must be replaced when the contact edge is worn;
the edge must be perfect for perfect drying. To replace the blades,
1. Bring the squeegee support to the high position, remove the vacuum pipe from the squeegee
(fig. 10) and partially loosen the screws
2. Remove the squeegee from the machine and place it on a bench.
3. Remove the screws from the front and back of the squeegee, then the steel straps and the worn
rubber blades
4. Now operate in the reverse order to assemble the new blades and adjust the squeegee.
