THE MACHINE DOES NOT CLEAN WELL
Check the state of wear and tear of the brushes and, if necessary, replace them (the brushes must be
replaced when the bristles are about 15mm long).
To replace the brushes, see “DISASSEMBLING THE BRUSHES” and “ASSEMBLING THE BRUSHES”.
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”).
THE SQUEEGEE DOES NOT DRY PERFECTLY
Verify that the squeegee rubbers are clean
Adjust the inclination of the squeegee (see "SQUEEGEE"
under “MACHINE PREPARATION”)
Check the suction tube is correctly inserted in its housing on the recovery tank
Disassemble the entire suction unit and clean it
Replace the rubbers, if worn
Check the suction motor switch is turned on
Check wheel adjustment
EXCESSIVE FOAM PRODUCTION
Check that a low foam detergent has been used. If necessary, add a small quantity of anti-foam 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.
