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.

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-
