WATER FLOW ADJUSTMENT FUNCTION

The water flow function in the machine's water system is regulated by the button (1) on the control panel (

Fig. 1

).

By pressing the button (1) for the first time, you can display in the control display the status of the water flow set in the machine 

at that precise moment (

Fig. 2

), each time the button (1) is pressed, the water level increases, and the flow rate will be 

zeroed once the maximum level is reached. The water flow rate changes by pressing the button again, there are 8 selectable 

levels (also counting the zero level). If the button (1) is kept pressed for more than three seconds, the water flow rate in the 

machine's water system is reset.

The water flow rate level refers to the flow delivered at maximum machine speed, at intermediate speeds, the flow is reduced 

and is proportional to the value set.

DETERGENT SOLUTION FLOW ADJUSTMENT FUNCTION (CDS VERSION)

The detergent solution flow function in the machine's water system is regulated by the button (1) on the control panel (

Fig. 1

).

By pressing the button (1) for the first time, you can display in the control display the status of the detergent solution flow set 

in the machine at that precise moment (

Fig. 2

), each time the button (1) is pressed, the detergent percentage increases, and 

the flow will be zeroed once the maximum percentage is reached. The detergent solution percentage changes by pressing the 

button again, there are 8 selectable levels (also counting the zero level). If the button (1) is kept pressed for more than three 

seconds, the flow of detergent solution in the machine's water system is reset.

ECO-MODE FUNCTION

When the “ECO MODE” function is activated, by means of the appropriate key (3) on the control panel (

Fig. 5

), the speed of 

the brushes' gearmotor and of the vacuum motor is reduced, in this way the energy consumption is reduced.

The Eco-mode function can only be used with working programs: drying; scrubbing with drying and scrubbing without drying.

When the eco-mode function is active the symbols of the vacuum motor (4) or the brush (5) or both, depending on the working 

program selected, will be shown on the control display as shown in the figure (

Fig. 6

).

MOVEMENT SPEED ADJUSTMENT

When the button (7) on the control panel (

Fig. 8

) is pressed it allows to adjust the speed of machine's movement, the level 

selected can be viewed by looking at the symbol (8) on the control display (

Fig. 9

).

Each time the button (7) is pressed, the speed level of the machine's movement is increased, once the maximum level has 

been reached, the speed will start again from the first level. Pressing the button subsequently changes the movement speed of 

the machine, there are 3 selectable levels (50% - 75% - 100%).

the reverse speed is lower than the forward speed to comply with current health and safety standards.

EXTRA-PRESSURE FUNCTION EXERTED ON THE BRUSHES

The extra-pressure function applied to the brushes is adjusted by means of the button (9) on the control panel (

Fig. 10

).

By pressing the button (9) for the first time, you can display in the control display the level of extra-pressure exerted on the 

brushes at that precise moment (

Fig. 11

), each time the button (9) is pressed, the extra-pressure level increases, and the 

extra-pressure will be zeroed once the maximum level is reached. The extra-pressure changes by pressing the button again, 

there are three selectable levels (also counting the zero level). If the button (9) is kept pressed for more than three seconds, 

the extra-pressure is reset.

The set level is displayed with the weight symbol above the brush symbol in the control display.

HOUR METER

Through the control display, in the screen after switching on, it is possible to view the hours of work performed by the machine in the central part of the 

screen (

Fig. 13

).

The first line shows the total time the machine (11) has been used and the second line indicates the partial time of the use of the machine (12).

N.B.:

 The numbers followed by the letter “h” identify the hours, while the numbers followed by the letter “m” identify the tenths of an hour (a tenth of 

an hour corresponds to six minutes).
