dangerous situation for the suction motor should 

never occur. In any case, a safety float turns off 

the suction motor if the dirty liquid level is too high.



 If water or foam starts leaking from under the 

tanks for any reason, immediately turn off the suc-

tion motor and empty the recovery tank. 

To drain the tank:

Drive the machine to a suitable location to drain 

the dirty water and preferably near a toilet or a 

sewer drain (comply with the national regulations 

for waste water disposal). 

Turn off the machine and remove the key from the panel.

Detach the drain hose from the hook and, keeping 

it high, unscrew the plug.

Lower the drain hose toward the selected drain-

age point.

The emptying operation can be interrupted quickly 

and whenever required just by raising the drain hose.

Check the quantity of residual dirt in the tank and, 

if necessary, clean the interior through the inspec-

tion hole, lifting the cover and the funnel at the top.

Carefully position the funnel inside the inspection 

hole and close the top cover, tightening the lock 

handles after each inspection/cleaning operation. 

Fully tighten the drain hose with the screw plug 

and hang it on the support behind the machine.

☞

 The top cover of the tank and the drain hose 

plug must be airtight, otherwise the subsequent 

pressure loss will reduce drying efficiency.

DRIVING THE MACHINE

Select the running direction using the Forward/

Reverse lever.

Insert and turn the ignition key.

Using the right foot lightly press the accelerator 

pedal and drive the machine to its destination.

Turn off the machine and remove the keys from 

the control panel.

The running direction can be changed using the 

forward/reverse lever, even while pressing on the 

accelerator pedal.

7.7 WORK 

METHOD

7.7.1 

PREPARATION AND WARNINGS

Remove any loose solid residue from the surface 

to be treated (using suitable tools, such as vacuum 

cleaners, sweepers, etc.). It this is not done, the 

solid dirt might prevent the squeegee from operat-

ing correctly, reducing drying efficiency.

This machine can driven only by trained personnel.

7.7.2 

ADJUSTING THE AMOUNT OF THE 

DETERGENT IN THE CLEANING SOLUTION

The adjustment of the amount of detergent to be 

used in the cleaning solution is carried out through 

the push selector on the control panel (Photo N - 3).

Pressing the selector multiple times will increase 

the amount of detergent dispensed; the dilution of 

the detergent dispensed is displayed on the control 

panel (Photo N - 7) through progressive levels hi-

ghlighted in the graphic symbol (Photo O).

The percentage of dilution of the detergent varies 

depending on the amount of clean water delive-

red, adjustable through the control lever (Photo H 

- 1); when the clean water outflow is half of the 

total possible amount, the percentage of dilution 

is shown in Photo O - 1; when the clean water 

outflow is set on the full amount the dilution per-

centage is shown in Photo O - 2.

7.7.3 DIRECT SCRUBBING OR FOR 

SLIGHTLY DIRTY SURFACES

Scrubbing and drying in a single pass.

Prepare the machine as previously described.

Select the forward direction using the direction 

lever.

Insert and turn the key.

Activate the suction motor, the brush motor and 

the detergent solution supply.

Lower the brushes and the squeegee.

Use the detergent adjustment lever to regulate the 

solution outlet flow (depending on advancement 

speed).

Lightly press the advancement pedal and check 

that all systems are working.

Fully depress the accelerator to increase the work 

speed.

Adjust the maximum advancement speed and the 

detergent solution flow as required.

The steering wheel is similar to a car steering 

wheel: it can be used to turn the machine around 

itself by steering all the way to one side.

To avoid damage to the surfaces being treated, the 

brush motor will stop automatically about 2 sec-

onds after the advancement pedal has been com-

pletely released.



  Remember to lift the squeegee before 

driving reverse to avoid damaging it.

☞

 Never use the machine without the detergent 

solution: the floor might be damaged.

7.7.4  INDIRECT SCRUBBING OR FOR 

VERY DIRTY SURFACES

Scrubbing and drying in various passes.

Prepare the machine as previously described.

First set of operations:

Select the forward direction using the direction 

lever.

Insert and turn the key.

Activate the brush motor and the detergent solu-

tion supply.

Lower the brushes.

Use the detergent adjustment lever to regulate the so-

lution outlet flow (depending on advancement speed).

Lightly press the advancement pedal and check 

that the brushes and solution feed system are 

working.

Fully depress the accelerator to increase the work speed.

Adjust the maximum advancement speed and the 

detergent solution flow as required.
