NOTE

The PMCS chart in this section contains all necessary unit preventive maintenance

checks and services for this equipment.

4-10. G e n e r a l . The trailer assembly and generator set must be inspected and serviced systematically to insure

that the power unit 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. Unit PMCS on the generator set is scheduled monthly or on a

per-hours-of-operation basis. The running time meter on the control panel is used to determine the operating time

of the generator set. Using the following as a guide, do the checks and services at the intervals shown. Observe

a l l 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 monthly (M) PMCS every month or 100 hours of generator set operating time.

c. Do your semiannual (S) PMCS once every six months or 500 hours of operating time.

d. 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.
