SWITCH” (Photo E - 6) within 2 seconds after 

switching on the machine with the key switch 

(Photo F - 1). The second LED of the speed indica-

tor (Photo E - 3B ) will be ON.

2) Press “INCREASE SPEED” (Photo E - 4)” key

within 5 seconds from the previous action; you

have now entered in the configuration mode.

THE CONFIGURATION SETTINGS ARE VISIBLE

ON THE SPEED INDICATOR LED:

1) The first two LEDs (Photo E - 3A, 3B) indicate

the type of setting of the indicator intervention th-

reshold an both must be ON;

2) The third and fourth LEDs (Photo E - 3C, 3D)

indicate the battery type: for the PB-Acid battery

only the third LED (Photo E - 3C ) should be ON,

while for the GEL battery both should be ON (Photo

E - 3C, 3D)

•

TO MODIFY CONFIGURATION SETTINGS:

1) The  “INCREASE SPEED” (Photo E - 4)” and “RE-

DUCE SPEED” (Photo E - 3) keys are used to set

the indicator’s intervention threshold in such a way

that the first two speed indicators LEDs (Photo E -

3A, 3B) turn ON;

2) The “BRUSH MOTOR SWITCH” (Photo E - 5)

is used to set the PB-Acid battery type while the

“SUCTION MOTOR SWITCH” (Photo E - 6) is used

to set the GEL battery type

•

TO SAVE THE SETTINGS AND EXIT THE MODE:

Press the “REDUCE SPEED” (Photo E - 3) switch

and the “SUCTION MOTOR SWITCH” (Photo E - 6)

simultaneously.

Once the settings have been set, we have different

MACHINE PREPARATION

•

Before starting to work, wear non-slip shoes,

gloves and any other personal protection device

indicated by the supplier of the detergent used or

considered necessary based on the operating en-

vironment.

☞

Do the following before starting to work. Refer

to the relative sections for a detailed description of

these steps:

Heck the battery charge level and charge, if ne-

cessary.

Mount the brushes or scraper disks (with the abra-

sive disks) that are suitable for the surface and

work involved.

Mount the squeegee, check that it is solidly atta-

ched and connected to the suction hose and that

the drying blades are not too worn.

Make sure that the recovery tank is empty. If not,

empty it completely.

Check and completely close the detergent solution

release control.

Fill the detergent solution tank with a mix of clean

water and non-foaming detergent in an adequate

concentration through the anterior hole. Leave 2

cm between the mouth of the plug and the level

of the liquid.

☞

To avoid risks, become familiar with the machine

movements, carrying out test runs on a large sur-

face without obstacles.

To obtain the best results in terms of cleaning and 

equipment service life, you should do the following
