4. Check that the recovery tank is not full.
5. Check that the float switch (2) (optional) in the
recovery tank is assembled correctly.
6. If, both in mode (MAN) as (AUTO), the signal
lamp (8) is on but the suction system does not work,
it is necessary to rotate the recovery tank (see under
paragraph "ACCESS TO THE BATTERY COMPART-
MENT") and check the connection of the suction mo-
tor plug situated at the bottom of the tank.
If the problem persists, please contact the authorized
technical assistance.

1. Verify that the key switch is positioned clockwise
to switch on the machine.
2. Check the charge level of the batteries on the
display (1).
3. Verify of having activated correctly the function
of washing with the brushes (see under paragraph
"STARTING OF THE MACHINE").
4. Check that the solution valve is open (see under
paragraph "FLOW ADJUSTMENT OF THE DETERGENT
SOLUTION").
5. If, both in mode (MAN) as (AUTO), the signal
lamp (20) is on but the detergent solution does not
come down onto the brushes, it is necessary to:
a. check the level of the liquid in the tank.
b. check that the solution filter is clean (see un-
der paragraph "CLEANING OF THE SOLUTION
TANK AND OF THE OUTER FILTER").
c. check that the inner filter of the solution tank
is clean (see under paragraph "CLEANING OF
THE INNER FILTER SOLUTION TANK").
If the problem persists, please contact the authorized
technical assistance.
THE MACHINE DOES NOT CLEAN PROPERLY
1. The brushes do not have the suitable bristle di-
mension: contact the authorized technical assistance.
2. The brushes have got worn bristles. Check the
brushes wear condition and eventually replace them
(the brushes have to be replaced when the bristles
have reached a height of about 15mm).
To replace the brushes, see instructions under para-
graph "BRUSHES DISASSEMBLY" and "BRUSHES AS-
SEMBLY".
3. The detergent solution is insufficient: open more
the solution valve (see under paragraph "FLOW AD-
JUSTMENT OF THE DETERGENT SOLUTION").
4. Check that the liquid detergent is in the recom-
mended percentage.
5. Increase the brushes base pressure (see under
paragraph "ADJUSTMENT OF THE BRUSHES PRES-
SURE").
Contact the authorized technical assistance for ad-
vice.
THE SQUEEGEE DOES NOT DRY PERFECTLY
1. Check that the suction function is on and that
the recovery tank is not full.
2. Check that the squeegee rubbers are clean (see
under paragraph "SQUEEGEE CLEANING").
3. Check the adjustment of the height and the in-
clination of the squeegee (see under paragraph "AD-
JUSTMENT OF THE SQUEEGEE").
4. Check that the suction and the squeegee hoses
are correctly inserted in their proper seats on the re-
covery tank.
5. Clean the suction filter (see under paragraph
"SUCTION FILTER CLEANING").
6. Clean the squeegee hose (see under paragraph
"SQUEEGEE HOSE CLEANING").
7. Replace the rubbers if worn out.
EXCESSIVE FOAM PRODUCTION
Check that low foam detergent has been used. Even-
tually add small quantities of anti foam liquid into
the recovery tank.
Please be aware that a bigger quantity of foam is
produced when the floor is not very dirty. In this ca-
se please dilute detergent solution.
