THE MACHINE DOES NOT CLEAN SATISFACTORY
1.
Check the condition of the brushes and replace them, if necessary (the brushes have to be
replaced when the bristles reach around 15 mm)
2.
Check that the brushes pressure is sufficient, eventually increase it (see “BRUSHES PRESSURE”
under “PERFORMANCE”)
3.
Use a different kind of brushes to the ones fitted as standard. For cleaning operations on floors
where the dirt proves to be particularly resistant, we recommend using special brushes which
may be supplied optionally according to needs (see under “CHOICE AND USE OF BRUSHES”).
THE SQUEEGEE DOES NOT DRY PERFECTLY
1.
Check that the squeegee is clean
2.
Adjust the height of the squeegee support (see under “MACHINE PREPARATION”)
