Section V. PREVENTIVE MAINTENANCE CHECKS AND SERVICES
NOTE
The PMCS chart in this section contains all necessary unit preventive maintenance
checks and services for this equipment.
4-10. General. The trailer assembly and generator sets must be inspected and serviced systematically to
insure that the power plant is 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
trailer is scheduled to be performed semiannually or annually. Unit PMCS on the generator sets is scheduled
monthly or on a per-hours-of-operation basis. The running time meters on the control panels are used to
determine the operating time of the generator sets. Using the following as a guide, do the checks and services at
the intervals shown. Observe all CAUTIONS and WARNINGS.

Perform your monthly (M) PMCS every month or 100 hours of generator set operating time.
Do your semiannual (S) PMCS once every six months or 500 hours of operating time.
Do your annual (A) PMCS once every twelve months or 1,000 hours of operating time.
