TROUBLESHOOTING
71.
INSUFFICIENT WATER ON THE BRUSHES
1.
Check that there is water in the solution tank, the amount inside the tank can be seen by
means of the level tube (01) on the front left of the seat.
2.
Make sure that the detergent solution tap is open, and check that the knob (02) on the
back of the steering column is completely lowered.
3.
Check that the water flow in the water system is not at zero, and with the machine on
press the button (03) once to view the delivery level. (versions with CDS)
4.
Check that the detergent flow in the water system is not at zero, and with the machine on
press the button (04) once to view the delivery level. (versions with CDS)
5.
Clean the solution filter located at the front of the machine.
6.
Make sure the water distribution pipe (05) (S versions) is not blocked.
7.
For the Innova 60B versions with “KIT WATER MANAGEMENT”, check that the choke
bushing is not blocked.
72.
THE SQUEEGEE DOES NOT DRY PERFECTLY
1.
Check the squeegee is clean.
2.
Check the squeegee adjustments (read the section “SQUEEGEE ADJUSTMENT”).
3.
Clean the whole vacuum unit (read the relevant sections in the chapters “DAILY
MAINTENANCE” and “WEEKLY MAINTENANCE”).
4.
Replace the rubber blades if worn out (read the section “REPLACING THE SQUEEGEE
RUBBER BLADES).
5.
Check that the cap on the recovery tank drainage hose is properly closed.
73.
THE MACHINE DOES NOT CLEAN WELL
1.
Check the state of wear and tear of the brushes and, if necessary, replace them. The
brushes should be changed when the bristles are about 15 mm long. To do this, read
“REPLACING THE DISC BRUSH” for Innova 65-75-85-100 B versions, or “REPLACING THE
CYLINDRICAL BRUSH” for the Innova 70S version. Working with over-worn brushes may
cause damage to the floor.
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”).
74.
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.
75.
THE VACUUM CLEANER DOES NOT FUNCTION
1.
Check whether the recovery tank is full and, if necessary, empty it.
2.
Check the float on the vacuum cap is working properly (see also “CLEANING THE
RECOVERY TANK” and “CLEANING THE RECOVERY TANK FILTER”).
