SILENT-MAX FUNCTION
This machine has a SILENT-MAX function for reducing the noise generated by the suction motor. The SILENT function is always active in the
machine by default. To deactivate the SILENT function, press the button (4) on the control panel (Fig.2).
N.B.: When the SILENT function is active, "LO” will appear on the control display (Fig.4).
N.B.: When the MAX function is active, "HI” will appear on the control display (Fig.5).
ADJUSTMENT OF THE DETERGENT SOLUTION FLOW
To adjust the ow of detergent solution during work, proceed as follows:
1. During the rst few working meters check that the amount of solution is sucient to wet the oor, but not enough to be collected by the
squeegee.
2. If the amount of solution that comes out is not right, use the “+” and “-” buttons (3) on the control panel to adjust it (Fig.1).
N.B.: The detergent solution ow regulation function is only active when the gearmotor in the brush head body is active.
N.B.: The rst time one of the two symbols shown above in the control display are pressed, the current level of detergent solution will be
shown for two seconds (Fig.3).
N.B.: The ow of detergent solution onto the brush can be adjusted to four levels, from “H2O 0” to a maximum of “H2O 3”. The level can
be seen by the text on the control display (Fig.3).
N.B.: If the ow is adjusted to “H2O 0” is no emission of detergent solution.
