4-10. GENERAL.
The trailer assemblies and generator sets of the power plants must be inspected and service systematically to ensure
that the power plants are ready for operation at all times. Inspection will allow defects to be discovered and corrected
before they result in serious damage or failure. Table 4-1 contains a tabulated list of preventive maintenance checks and
services to be performed by unit maintenance personnel. All of the unit PMCS on the trailers are scheduled to be
performed semiannually. Unit PMCS on the generator sets are scheduled weekly or on a per-hours-of-operation basis.
The running time meter on the control panel is used to determine the generator set operating time. Using the following
as a guide, do the checks and services at the intervals shown. Observe all CAUTIONS and WARNINGS.
a.
For PMCS performed on an operating time basis, perform your hourly (H) PMCS as close as possible to the time
intervals indicated.
NOTE
For units in continuous operation, perform PMCS before starting operation if continuous
operation will extend service interval past that which is shown.
b.
Perform your weekly (W) PMCS every week or 4U hours of generator set operating time.
c.
Perform your monthly (M) PMCS every month or 10u hours of generator set operating time.
d.
Do your semiannual (S) PMCS once every 6 months.
e.
If you discover a problem with the equipment, refer to Section VI, Troubleshooting. If you cannot correct the
problem, refer to paragraph 4-12, Reporting Deficiencies.
