Definition of Preventive Maintenance
Preventive maintenance means making systematic checks and adjustments
at regular intervals to keep the equipment operating at top efficiency. It
is not the same as troubleshooting or repair. The purpose of
troubleshooting and repair is to locate and correct existing defects.
Preventive maintenance is designed to prevent the development of defects.
The importance of preventive maintenance cannot be overemphasized. Failure
or inefficient operation of one piece of equipment may cause the failure of
the entire photographic system. It is vitally important, therefore, that
operators and repairmen maintain their equipment properly.
