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.

THE AUTOMATIC WATER/DETERGENT DOSING SYSTEM DOES NOT WORK
The automatic water/detergent dosing system has been designed with criteria of extreme
sturdiness and reliability, but there is a special by-pass system that allows you to use the
machine even if the system is out-of-use.
To by-pass the automatic water/detergent dosing system, you must rotate the tap lever (01) on
the rear-centre of the base downwards; in this way you can go on working even with the system
out-of-use. Remember, however, to put not only water in the solution tank, but the right
quantities of both water and detergent. With the dosing system out-of-use, the water flow is
regulated via the tap on the steering column.
Contact an Authorised Retailer to have the system repaired.
