Receiving the machine
Immediately check, when receiving the machine, that all the material
indicated on delivery documents has been received and also that the
machine has not been damaged in transit. If it has been damaged,
this damage must be immediately reported to the shipper and also to
our customer service department. Only acting promptly in this manner
will make it possible to receive missing material and to be
compensated for damage.
Foreword
This is a floor scrubbing machine that is able to clean any type of floor
by using the mechanical action of the rotating brush and the chemical
action of a water-detergent solution. As it moves forward it also
gathers up the dirt removed and the detergent solution that has not
been absorbed by the floor.
The machine must only be used for this function. Even the best
machines will only operate efficiently and work with profit if they are
used properly and kept in perfect operating order. Read this
instruction booklet carefully and consult it every time problems arise
with machine operation. Remember that, if necessary, our service
organization, in collaboration with our dealers, is always available for
helpful hints or direct intervention.

3. INSERTING THE BATTERIES IN THE MACHINE
Figure 6
Batteries must be housed in the battery compartment (Figure 6) provided under the tank. They
must be handled using lifting equipment suitable both for their weights and for the hook-up
system.
They must also comply with the requirements specified in CEI 21-5 standards.
WARNING: Comply scrupulously with the instructions given by the
manufacturer or his retailer for daily battery charging and maintenance. All
installation and maintenance procedures must be done by expert
personnel. Danger of inhalation of gases and leakage of corrosive fluids.
Danger of fire: do not approach with open flames.

1. Open the rear hook and pull out the battery compartment (1)
2. The machine is supported by stand (2) that automatically lowers when the battery
compartment is removed
3. Check that the trestle is in the right position.
Figure 8
4. Put the batteries in place.
5. Connect the cable terminals with the connector in position 01 (fig. 8)
6. Connect the bridge cable terminals to position 02 (fig. 08).
7. Insert the battery compartment in its housing and block everything in place with the
previously-actuated hook (fig. 7)
WARNING: This procedure must be performed by qualified personnel.
Mistaken or imperfect connection of the cables on the batteries may cause
severe damage to persons or property
4. RICARICA BATTERIE
Figure 9
Perform a deep charge cycle before start using the machine.
If the batteries replacement needed be sure to install batteries suitable with battery charge (use
only 12V AGM o Gel batteries).
After having turned off the machine, remove the protection lid and plug the power supply cable to
the battery charger, then plug the power cable to the electric supply plug. To use properly the
battery charger refer to the battery charger manual.
WARNING: The machine has an automatic system that remove the power
supply to the electric plant of the machine when the batteries are in
charging conditions.
WARNING: To not damage permanently the batteries you have to not
discharge completely them to avoid a complete discharge. Recharge them
as soon as the low battery level signal appear.
WARNING: Never left the battery totally discharged as well the machine
will not be used.
WARNING: For the daily recharge of the batteries you need to follow
scrupulously the manifacturer indications. All the installation and
manintenance operations had to be performed by authorized personnel
only. Gas leakage and acid leakage hazards. Fire hazard, don’t approach
flames.

5. CONNECTING THE BATTERY/SYSTEM CONNECTOR
Figure 11
Battery connector (2) must be connected to machine connector (1).
6. BATTERY CHARGE LEVEL GAUGE
Figure 12
The battery charge level gauge operates with a microprocessor. The lighted LEDs on the display
give an approximate reading of the level of charge:
4 = maximum charge, 3= 3/4 charge,
2= 2/4 charge, 1= 1/4 charge,
0= batteries discharged (flashing).
WARNING! The brush motor automatically turns off a few seconds after
the flashing “0” appears. The remaining charge permits to finish drying
before carrying out recharge

13. DETERGENT SOLUTION
Figure 20
Unscrew the solution tank filling plug.
Fill with clean water at a temperature that does not exceed 50°C. Add liquid detergent in the
concentration and according to the procedures recommended by the manufacturer. Use only a
minimal percentage of detergent to prevent formation of an excess amount of foam since too
much foam may damage the suction motor. Put the plug back in its place.
WARNING: Always use low-foam detergent. Introduce a small amount of
anti-foam liquid in the recovery tank before starting to work to be sure to
prevent foam from being generated. Never use pure acids.

CHECKING OPERATION
1. INSUFFICIENT WATER ON THE BRUSHES
1. Check that the main switches and solenoid valve are on (fig. 22)
2. Check that the cock is open (fig. 16)
3. Check that there is water in the solution tank.
2. THE MACHINE DOES NOT CLEAN WELL
1. Check the condition of wear of the brush and replace as necessary (the brush must be replaced
when bristles are about 15 mm tall).
To replace the brush refer to “DISMANTLING THE BRUSH” (fig. 35) and “INSTALLING THE
BRUSH” (fig. 17).
2. Use a type of brush different from the standard brush. When cleaning floors where dirt is
particularly difficult to remove you should use special brushes. These are supplied on request to
meet specific requirements (see: “BRUSH SELECTION AND USE”).
3. THE SQUEEGEE DOES NOT DRY PERFECTLY
1. Check that the squeegee rubbers are clean
2. Check that the suction tube is properly inserted in its housing on the recovery tank
3. Dismantle the entire suction unit and clean it (fig. 29-30-31)
4. Replace rubbers if worn (fig. 33-34)
5. Check that the suction motor is on (fig.23)
4. TOO MUCH FOAM IS GENERATED
Check that low-foam detergent is being used. If necessary add a small amount of anti-foam liquid to
the recovery tank.
Remember that more foam is generated when the floor is not very dirty. Dilute the detergent more
when cleaning floors that are not very dirty.

20
BRUSH SELECTION AND USE
POLYPROPYLENE BRUSH (PPL)
This is used on all types of floors and offers good resistance to wear and to hot water (not more than 50°C). PPL is not hygroscopic and
consequently preserves its characteristics even when wet.
BRISTLE THICKNESS
The thicker bristles are more rigid and consequently are used on smooth floors or with thin gaps.
It is better to use softer bristle brushes on uneven floors or floors with deep gaps or humps since these penetrate more easily.
Remember that when brush bristles are worn and then too short they become rigid and are unable to penetrate and clean in depth. Bristles which
become too big, among other things, cause the brush to tend to skip.
DRIVE DISK
Drive disk, recommended for cleaning polished surfaces, is equipped with a set of anchor stubs that retain and drive the abrasive disk during
operation.
