the prescriptions issued by the Safety Authorities and must also perform all the specific
operations listed in this chapter.
NOTE:
All the information on maintenance concerns solely and exclusively routine

The operations for machine set-up and adjustments must be performed by one person only, under the
supervision of the maintenance Supervisor.
Untrained or unauthorised personnel must not enter the machine working area when the machine is
under maintenance.
Maintenance operations must be carried out in adequate lighting conditions; in case of maintenance
work to be carried out in areas with insufficient lighting, use portable worklights; take care to avoid

Precautions and warnings when preparing the machine for routine
maintenance.
The maintenance technician must:
Be aware that there may be hazards in carrying out these operations.
Comply with all the warnings shown on the machine, on the diagrams, in this document and in the
attached documentation to avoid faults that in turn could directly or indirectly cause serious accidents,
injuries to persons or damage to property.
Use the personal protective equipment described in the following paragraph.
Avoid physical contact with the moving parts of the machine.
The operator must also take into account the following:
ELECTROCUTION HAZARD:
Maintenance operations that require the presence of electrical
power, such as troubleshooting in the electrical panel, must be performed solely and
exclusively by expert personnel, according to the safety procedures in force on the premises in
which the machine is installed.
WARNING:
Any technical modification affecting the operation or safety of the machine must be
carried out exclusively by the manufacturer’s technical personnel or by technicians formally
authorised by the manufacturer. Failure to observe this recommendation exonerates Ragazzini
S.r.l. from all responsibility concerning the resulting alterations or any consequent damage.
The guards and safety devices may be fully or partly removed during maintenance operations
exclusively by expert and/or authorised personnel, who must ensure that all removed safety
devices/guards are duly refitted in their original position as soon as maintenance operations
have been completed. The machine must not be started up after maintenance operations have
been performed until the guards and other safety protections have been refitted.
