Preventive Maintenance Maintenance
4.3 Preventive Maintenance
Preventive maintenance consists of a systematic routine that maintains maximum
efficiency and reduces the possibility of a malfunction. This routine includes inspection,
cleaning, and adjustment of the equipment.
4.3.1 Inspection
This equipment consists primarily of solid state circuits that require no routine
maintenance. Periodic inspection and testing will be required to insure that the equipment
still meets its performance specifications.
At the time that the tests are performed, the equipment should be inspected for damaged
components, loose or frayed connections, and corrosion on metal surfaces. In the event
that a malfunction or damage is found, it must be corrected immediately.
4.3.2 Cleaning
When the equipment is inspected and tested, it should also be cleaned. Accumulations of
dust and dirt can impair cooling and generally distracts from equipment appearance.
A soft cloth and a commercial cleaner (such as Windex“) may be used to clean the paint
and the lens. Be careful not to get the cleaner into any switches.
4.4 Corrective Maintenance
Corrective maintenance procedures are used to help maintenance personnel isolate an
equipment malfunction.
These procedures imply a troubleshooting technique that uses the drawings and aids
supplied in the manual along with a thorough knowledge of troubleshooting sophisticated
electronic equipment.
4.4.1 Basic Troubleshooting Procedures
The following suggestions are general in nature, based upon established troubleshooting
techniques. When followed, they aid in minimizing equipment down time. Any procedure
given, however, is only a guide and may be deviated from whenever expedient.
4.4.2 Operating Procedures
Often what appears to be a malfunction, is the result of improper operation or application
of the equipment. Upon encountering a problem thoroughly evaluate the operating
procedures that were used when the malfunction occurs. Check external loads where
applicable.
