5.3 MAINTENANCE OF THE SUCTION MOTOR
The suction motors must be checked and cleaned. Every six months, the brushes should be checked and
replaced, too - if necessary. Suction motor maintenance should be carried out as follows:
Remove the key from the control panel to prevent unwanted machine starts.
Lift the suction unit compartment cover (detail 1).
Pull out the machine electric system plug (detail 2).
Release the motor casing fixings (detail 3) to be able to separate the motors from their support
plate.
Replace the motor brushes by unscrewing the brush holder and removing the faston connector.
5.4 WIRING SYSTEM CHECKS
The machine wiring system should be inspected and examined every 2 years. It is very important to
immediately correct any defects, e.g. disconnected wires or burnt cables.
Any service on the wiring system should be carried out by a skilled technician.
Any maintenance or repair not described as routine maintenance should be carried out by
specialised personnel authorised by FIORENTINI.
