ELECTRIC FUSES AND THERMAL CUT-OUTS
In addition to general 80 A fuses, the machine is also fitted with self-restoring safety fuses located on
the boards in the electric system that interrupt the power supply to the brush and vacuum motor when
the machine exceeds the predetermined load. To restore the power supply to the motor, switch off the
machine and wait for the fuses to cool down (about 40 seconds). If the switch disconnects the current
several times in a row, contact the specialised technical assistance centre.
40.
THE MACHINE DOES NOT CLEAN WELL
4.
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 15mm long. To replace them, see “CENTRAL
BRUSH REPLACEMENT”, or “SIDE BRUSH REPLACEMENT”. Working with over-worn brushes
may cause damage to the floor.
5.
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”).
6.
The side brush is worn, to adjust it see “SIDE BRUSH ADJUSTMENT”.
7.
The debris hopper is full, empty it completely.
41.

The flaps that ensure efficient vacuum action are worn: replace them.
2.
The front flap is broken and the machine projected heavy dirty bodies forward: replace them.
