INTRODUCTORY COMMENT

Thank you for choosing our machine. This oor cleaning machine is used for the industrial and commercial cleaning and
is able to clean any type of oor. During its operation, the combined action of the brushes and the detergent solution

removes the dirt which is recovered through the rear suction assembly, giving a perfectly dry surface. The machine must
be used only for such purpose. It gives the best performance if it is used correctly and maintained in perfect working order.

We therefore ask you to read this instruction booklet carefully whenever difculties arise in the course of the machine’s

use. We ask that you contact our service department for all advice and servicing as may prove necessary.

BATTERY INSTALLATION

The machine is equipped either with batteries in serial connection
or elements of DIN-type assembled together and connected in
series, placed in its appropriate compartment under the recovery
tank and must be handled using suitable lifting equipment (due
to weight, considering the type of batteries chosen, and coupling
system).

The batteries must be in accordance with CEI 21-5 Norms.

The machine is originally set for the use of standard traditional lead/
acid batteries.
CHECK SETTING ON THE INDICATOR (see under paragraph
"BATTERIES CHARGE LEVEL INDICATOR").
In case of GEL or AGM batteries installation, it is necessary TO
MODIFY THE SETTING (see under “TO CHANGE THE BATTERY

SETTINGS”).

Strictly follow manufacturer/distributor indications for the main­tenance and recharge of the batteries. All installation and main­tenance operations must be executed by specialized staff, using
suitable protection accessories.

ACCESS TO THE BATTERY COMPARTMENT

To reach the battery compartment, rst of all make sure that the

recovery tank (1) is empty by opening the cover (2).
If the tank is full, proceed as indicated under “RECOVERY TANK
CLEANING”, otherwise take off the squeegee hose (3) and lift the

tank.

Be sure that the battery recharger is suitable for the installed batter­ies both for their capacities and type (lead/acid or GEL or AGM).

In the plastic bag containing the use and maintenance you will nd

the coupling connector for the recharger. It must be assembled onto
the cables of your recharger, following the instructions given by the
manufacturer.

ON-BOARD BATTERY RECHARGER (OPTIONAL)

If the machine is equipped with the on-board battery recharger (see
under "OPTIONAL ACCESSORIES”) please refer to the manufac­tures instructions on the use of the charger. The battery recharger
is connected directly to the battery poles. During the recharging
operations a device is activated which does not permit the ma­chine's functioning. The main cable of the battery recharger has a
maximum length of two meters and must be connected to a single­phase socket type CEE 7/7.

4. Maintain the connection with the battery recharger until the indi­cation of the end of charge is observed on the charger.

Never disconnect the batteries connector during the recharging
phase.

Never leave the batteries completely discharged even if the ma­chine is not used. In case of traditional lead/acid batteries, please
check the electrolyte level every 20 recharging cycles and as
needed, top up with distilled water at the end of the recharge. Never
leave the batteries discharged for more than two weeks.

Danger of gas exhalations and emission of corrosive liquids. Fire

danger: do not approach with free ames.

BATTERIES DISPOSAL

It is compulsory to dispose of exhausted batteries, classied as

dangerous waste, to an authorized institution according to the cur­rent laws.

SQUEEGEE ASSEMBLY

1. Maintain the squeegee support (1) slightly lifted from the oor.

2. Insert the threaded parts of the two knobs (2) making them slide
inside the two slots on the support. Pay attention to put the wash­ers (3) into position, there are two for each knob, so that they are
assembled one under and the other on top of the two slots present
on the support.

BATTERIES RECHARGING WITH ON-BOARD CHARGER (OP­TIONAL)

Bring the machine on a leveled surface near to a single-phase
120V 60 HZ socket (within 2 m), nominal current 10A.
Switch off the machine and proceed as follows.

1. Insert the plug into the mains socket.

2. Proceed to the recharging keeping the recovery tank lifted (see
under paragraph “ACCESS TO THE BATTERY COMPARTMENT”
in “BEFORE USE”).

3. Do not take off the plug from the mains socket until the end of
charge. At the end of the recharging, remove the plug from the
mains socket.

3. Attach the squeegee by rotating the two knobs (2) clockwise.

4. Insert the squeegee hose (4) into its coupling as shown in the

gure.

10

ADJUSTMENT OF THE SQUEEGEE

In order to have a perfect drying result through the squeegee, the
rear rubber must have the lower bending uniformly adjusted in all
its length. For the adjustment, it is necessary to put the unit in work­ing condition and therefore the suction motor has to be switched
on and the brushes have to function together with the detergent

solution.

The bending is not uniform
Adjust the squeegee inclination rotating counterclockwise the wing
nut (1) to increase the bending in the central part, or clockwise to
increase the bending on the extremities.
Height adjustment
Once the squeegee inclination has been adjusted, it is necessary to

x this optimum condition making the wheels lightly touch the oor.

Release the wheels rotating counterclockwise the register (2), ro­tate the register (3) to raise or to lower the wheels until the desired
bending is reached.
At the end block again the wheels through the register (2).

BRUSHES ASSEMBLY

To assemble the brushes, pro­ceed as follows:

1. Switch on the machine turning
the key (1) clockwise.

2. Press the push button (2) of
up/down of the brushes base to
lift the brushes.

3. Switch the machine OFF by
turning the key (1) counterclock­wise.

With the brushes base group in lifted position, insert the brushes
into their plate seat underneath the brushes base turning them until
the three metal buttons are properly seated in their slots; quickly
rotate the brushes to push the button towards the coupling spring

until they get locked. The gure shows the rotating direction for

brushes coupling.

SPLASH GUARD ASSEMBLY

The two splash guards have to be assembled onto the brushes
base group. Insert the metal strips inside the slots on the rubber.

Place the round hole at the at extremity of the strip onto the screw

placed in the front of the cover. Secure the strips with the nut.

Screw down the knobs in the rear part of the cover in the free end
of the metal strips. The operation has to be carried out for each
splash guards. With the brushes assembled, the splash guard must

slightly touch the oor

For a longer life of the brushes we suggest to invert daily their posi­tion. Whenever brushes were deformed we suggest to reassemble
them in the same position, avoiding that the different inclination of
the bristles causes excessive motor overload or troublesome vibra­tions.

Use only brushes supplied with the machine or the ones indicated
in the paragraph “RECOMMENDED BRUSHES”. The use of other
brushes can compromise security.

STANDBY MODE

After a certain period of inactivity of the machine, it goes in stand­by mode and the display turns off. To start again press any button
on the instrument board, the display will turn on again and after few
seconds the machine returns to normal operations.

RECOVERY TANK

Verify that the squeegee hose coupling (1) is correctly inserted
into its seat and that the drain hose plug (2) is closed. The recov­ery tank is provided with a cover (3) that seals itself thanks to the
vacuum created by the suction motor during its use.

On the side of the machine there is a level hose that permits the
operator to easily see the solution level inside the tank both during

the lling of the tank and during operations.

DETERGENT SOLUTION TANK

The solution tank is provided with an inspection opening. This per­mits to cleaning of the exit point of the detergent solution. Be sure
that the cap is tightened after cleaning.

Screw down the plug of the solution tank.

Always use low foam detergent. To avoid foaming , before starting
working operation, add a small amount of anti-foam product into the
recovery tank.
Never use pure acid.

3S SYSTEM “SOLUTION SAVING SYSTEM” (OPTIONAL)

The system is composed
of a separate line parallel
to the main solution line. It
can be enabled or disabled
directly from the instrument
panel by holding for about
3 seconds the push button
