CHAP. 5. MAINTENANCE, BREAKS RESEARCH AND CLEANING
MAINTENANCE MAN REQUIREMENTS
With the term "maintenance" must not be understood only the periodical check of the machine normal functioning but also
the analysis and the consequent remedy of all causes that for any matter put it out of service. It is absolutely necessary that for
the maintenance, cleaning, parts change and breaks research activities performed from the user, this work is entrusted to
skilled personnel, competence and authorized from the employer.
All operations of maintenance, cleaning and parts change, none excluded, must be definitely performed with the machine
completely stopped and insulated from the external feeding sources.
MAINTENANCE PRESCRIPTIONS
PROTECTIONS REMOVAL AND/OR PROTECTION DEVICES
For any interventions described in the present chapter, it is necessary to remove from their position some fixed
protections.
The removal can happen only from the maintenance man.
At the end of the interventions, these protections must be replaced and blocked in their original position, with the fastening
systems, which were foreseen before the intervention.
The maintenance responsible must disconnect completely the machine, as here follow reported, before to proceed with the
removal of a fixed protection and/or with the element change.
INSULATION FROM THE EXTERNAL FEEDING SOURCES
Before to perform any operation of maintenance, cleaning and parts change, the external feeding sources must be sectioned
and insulated.
Position on "zero" the protection device placed upstream of the electric
equipment feeding line.
BREAKS OR DAMAGES RESEARCH AND MOVING ELEMENTS UNBLOCKING
Here follow are indicate the interventions for the breaks or damages research and moving elements unblocking which can
be performed from maintenance men.

MODALITY AND COMPARISONS
Contact the electric energy distributor
After having eliminated the causes that have determined the protection device
intervention, restore it. In case of problem persistency contact an electrician
technician.
Contact an electrician technician: after having eliminated the causes that have
determined the protection device intervention, restore it.
In case of fuses intervention, change them with types of the same model,
calibration and intervention curve.
Lifting the grater group pressure handle, the machine stops immediately for the
entry in function of the safety micro switch.
Lower the pressure up to the height that doesn't allow the fingers introduction
towards the grater roll and start the machine.
Contact directly the Authorized Assistance Center
Check and restore the electric energy.
Turn the sectioning devices in the position "ON"
Change the intervened fuses, check the magneto thermal switches state.
Check the START button efficiency and eventually contact directly the Authorized
Assistance Center.
Wait the complete cooling before the machine restarting
