1. Turn off the machine using the key switch.

2. Insert the plug into the mains socket.

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

4. Do not take remove the plug from the mains socket
until the indication of the end of charge is visualized.
At the end of the recharging, remove the plug from the
mains socket.

Never charge any battery with a non suitable re­charger. Strictly follow the instructions supplied by the
batteries and recharger manufacturer
NOTE: Never leave the batteries completely dis­charged for long periods, even if the machine is not
used. In case of traditional batteries, please check the
electrolyte level every 20 recharging cycles and even-

tually ll them up with distilled water. Never leave the

batteries discharged for more than two weeks.

If lead/acid batteries are installed, there could be the
risk of gas exhalations and emission of corrosive liq­uids.

Fire danger: do not approach with free ames.

BATTERIES DISPOSAL

It is compulsory to hand over 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 present 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.

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

4. Insert the squeegee hose (4) into its coupling, re-

specting its position as indicated in the gure.

14

ADJUSTING 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 oneself 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 by rotating the knob
(1) counterclockwise 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 slightly touch the oor. Release the wheels by

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).

The two splash guards have to be assembled onto
the brushes base group as indicated in the following

gures. Insert the metal strips inside the suitable slots

present on the rubber.
Attach the ends of the strip to the screw (1).
Lock the lever (2) to the ring placed at the free end of
the meal strip.
These operations have to be done for both the splash

guards. With the brushes assembled, the splash guards
must slightly touch the oor.

To disassemble the splash guards, do the same opera­tions in reverse order.

ASSEMBLING THE BRUSHES

To assemble the brushes, it is necessary that the
brushes base is in the lifted position. If it is not lifted,
proceed as follows:

Without the operator upon the unit, turn the key switch

clockwise, the display comes on and after 3 seconds
all working groups are turned off automatically and

are lifted from the oor.

Switch off the machine turning the key counterclock­wise.

With the brushes base group in lifted position lock the

brushes rotating them as in the picture below.

ASSEMBLING AND DISASSEMBLING THE
SPLASH GUARDS

15

For a longer life of the brushes we suggest to daily

invert their position. Whenever brushes result to be

deformed we suggest to reassemble them in the same
position, in order to avoid 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 manual “RECOMMENDED
BRUSHES”. The use of other brushes can compro­mise the good washing result.

FLOOR CLEANING
CONNECTING THE BATTERY CONNECTOR
AND SWITCHING ON THE MACHINE

Once the battery recharging has been completed:

1. Disconnect the connector (2) of the battery recharg­er from the battery connector (1).

2. Connect the battery connector (1) to the machine
connector (3).

DETERGENT SOLUTION TANK

The solution tank is provided with an inspection hole.
This hole allows users to clean the exit area of the
detergent solution.
Be sure that the cap is closed tight.

The capacity of the detergent solution tank is indi­cated in the technical data.
Open the screw plug placed in the left part of the

machine and ll the detergent solution tank with clean
water at a maximum temperature of 122°F (50°C).

Add the liquid detergent in the percentage and condi­tions recommended by the manufacturer. To avoid
excessive foam, which could cause problems to the
suction motor, use the minimum percentage of deter­gent. Screw down the plug to close the tank.

RECOVERY TANK

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

On the rear part of the machine is placed a level hose
that permits to easily see the solution quantity inside
the tank both during the lling of the solution and dur­ing the working.

16

Always use low foam detergent. To avoid foam pres­ence, before starting working operation, introduce into
the recovery tank a minimum quantity of anti-foam
product.
