WORK
If only the scrubbing function is needed, simply turn the button (04) on the control panel to "Pos.-02" and
the vacuum motor will immediately cease to function.
Once the scrubbing cycle is complete, turn the button (04) to "Pos.-01" to return to the scrub and dry
function.
If only the scrubbing function is needed without detergent solution, simply press the button (01) on the
control panel in the "II" position; the solenoid valve will stop working and the detergent solution supply will
cease.
27. REGULATING THE DETERGENT (B VERSION)
To regulate the detergent, proceed as follows:
1.
Ensure that the tap flow is at maximum capacity by turning the lever (01) on the right-hand rear part of
the machine anticlockwise.
2.
Check that the quantity of detergent solution in the solution tank is correct for the type of work to be
carried out; if not, refill the solution tank.
3.
Check that the brush head and squeegee are resting on the ground.
4.
Turn the key operated main switch to “I”.
5.
Press the “AUTO” button on the control panel.
6.
Press the dead man's lever under the control handlebar.
7.
During the first few metres of work, press the button (02) which controls the proportional solenoid valve
in order to increase the flow of detergent supplied to the brush; press the button (03) to decrease the
flow.
On pressing the detergent solution flow regulation buttons on the control display, a horizontal line will
appear, composed of five positions. As the buttons are pressed, small rectangles will appear. There are
five possible adjustments for the solenoid valve.
If the display only shows the horizontal line, no detergent solution is being released. This mode is used
when the floor is already wet or in general when the chemical action of water and detergent solution is not
necessary.
For each press of the button (02), the quantity of solution released will increase by one level. For each
press of the button (03), the quantity of solution released will decrease by one level. The quantity of
solution released can be set to five different levels.
WARNING! Holding the button (03) down brings the solenoid valve flow to zero.
WARNING! If the machine is switched off with the key operated main switch, the
selected detergent flow will remain in the machine memory.
