TROUBLESHOOTING
1. INSUFFICIENT WATER ONTO THE BRUSHES
1. Make sure that the cock is open (1). In this case the signal lamp must be on (2)
2. Make sure that there is water in the solution tank
3. In the machines with automatic version check that the solenoid valve switch is on
4. Clean the solution filter
2. THE MACHINE DOES NOT CLEAN SATISFACTORILY
1. Check the condition of the brushes and replace them, if necessary. The brushes have to be changed
when the bristles reach around 15mm. To work with worn brushes can cause floor damages
2. Check that the brushes pressure is sufficient (see under “BRUSHES PRESSURE”)
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”)
3. THE SQUEEGEE DOES NOT DRY PERFECTLY
1. Check that the squeegee is clean
2. Check the squeegee adjustments (see under “MACHINE PREPARATION”)
3. Clean the whole suction group (see under “DAILY MAINTENANCE”)
4. Replace the rubbers, if worn (see under “WEEKLY MAINTENANCE”)
4. THE SUCTION MOTOR DOES NOT FUNCTION
1. Check that the signal lamp of the suction motor switch is on
2. Check whether the recovery tank is full; eventually empty it
3. In the automatic versions, the suction motor works only when the squeegee is lowered. Check that
the selector is on the “AUTO” position and move forward of some metres.
