11. MAINTENANCE
Like all electrical equipment, this unit requires not only correct use, but
also maintenance and checks at regular intervals. This precaution will
guarantee that the equipment works safely and efficiently.
Periodic maintenance consists in checks carried out directly by the
operator and/or by the Technical Service.
The operator can carry out the following checks himself:
• check there are no oil marks on the tubehead
• check the remote control cable is not broken or scratched
• check there are no external damages to the equipment which could
make it unsafe in terms of protection from radiation
• check the scissors arm balance
• check that the X-ray beam is centered
• check proper functioning of X-ray exposure LED and exposure buzzer
• check the plates are intact and well attached.
The Service Engineer, during preventive maintenance, besides the checks
listed above, will verify also:
• correct adjustment of the rotation friction mechanism of the
extension arm and of the scissors arm
• correct balancing of scissors arm, making proper adjustment when
necessary.
NOTE:
The Service Engineer has to take special care for all what concerns
electrical safety of the device and must make sure of restoring all
provisions for electrical safety which may be affected during a service
intervention and to solicit the customer to have the electrical safety tests
repeated every time the intervention has caused the replacement of
important parts or the intervention has significantly affected safety
provisions of the device.
NOTE:
Interventions carried out by the Service Engineer must be noted in the
Maintenance Record page at the end of the User Manual, with a short
description of the actions done
