29. REGULATING THE DETERGENT (BT 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 fee meters of work, press the button (02) which controls the proportional solenoid valve
to regulate the flow of detergent solution released onto the brush.
On pressing the button (02) on the control display, a horizontal line will appear, composed of five positions.
As the button (02) is 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. The quantity
of solution released can be set to five different levels. Once the maximum level is reached (status shown in
the right-hand display), pressing the button (02) again will return the flow to level 0 (no supply).
WARNING! Passing from one step to another is a continuous cycle - it is not possible to
go back except by continuing to the end of the scale and starting again from zero.
WARNING! Holding the button (02) 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.
30. REGULATING THE DETERGENT (BB VERSION)
Firstly, fully open the tap outflow, by means of the lever (01) on the right-hand side at the back of the
machine. During the first few meters check that the flow of detergent solution is sufficient to wet the floor;
the flow of detergent solution is regulated by moving the lever (01). Turning the lever (01) anticlockwise
increases the flow of detergent into the water system, while turning the lever (01) clockwise reduces the
flow. Bear in mind that the correct amount of solution always depends on the nature of the floor, the degree
of dirt and the forward speed.
