2. THE MACHINE DOES NOT CLEAN WELL
1.
Check the state of wear and tear of the brush and, if necessary, replace it (the brush must be replaced
when the bristles are about 15 mm long).
2.
Use a different kind of brush to the one fitted as standard. For cleaning floors where the dirt is
particularly resistant, we recommend the use of special brushes supplied upon request and according
to needs (see “CHOOSING AND USING THE BRUSHES”).
3. THE SQUEEGEE DOES NOT DRY PERFECTLY
1.
Check that the squeegee rubbers are clean, if dirty clean them, or if worn replace them.
2.
Adjust the inclination and height of the squeegee (see the “ADJUSTING THE SQUEEGEE
INCLINATION AND HEIGHT” paragraph).
3.
Check the suction tube is correctly inserted in its housing on the recovery tank
4.
Check the inner filter of the recovery tank is not dirty and, if necessary, clean it thoroughly.
5.
Check that the suction motor switch is activated.
4. EXCESSIVE FOAM PRODUCTION
Check that a low foam detergent has been used. If necessary, add a small quantity of antifoam liquid to
the recovery tank.
Remember that, when the floor is not very dirty, more foam is generated. In this case the detergent
solution should be more diluted.
6. ELECTRICAL FUSES AND THERMAL PROTECTIONS (SYSTEM E)
The machine is fitted with the following electrical protection systems:
thermal trip units arranged on the outside of the handlebars, to protect the following motors:
1.
Base motor 5 A circuit breaker (1)
In the event of malfunctioning, check a thermal cut-out has not intervened. If the motor overheats, its
thermal cut-out intervenes to block the electricity supply. Wait a few minutes until it has cooled down, then
press the specific trip unit button to reactivate the power supply and motor operation.
