TM 5-6115-584-12 NAVFAC P-8-622-12 TO-35C2-3-456-1 TM-05682C-12 Section III. PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) 3-4. GENERAL. To ensure that the Generator Set is ready for operation at all times it must be inspected systematically, so that de- fects may be discovered and corrected before they result in serious damage or failure. The necessary preventive main- tenance checks and services that are to be performed by the Operator personnel are listed and described in paragraph 3-8. 3-5. CORRECTING AND REPORTING DEFICIENCIES. Defects discovered during operation will be noted for future correction. Stop operation immediately if a deficiency is noted which would damage the equipment or is a safety hazard. All deficiencies and short comings will be recorded together with the corrective actions taken on the applicable form. Marine Corps users should refer to current issue of TM 4700-15/1. 3-6. DETERMINING PMCS INTERVALS. Certain Operator PMCS on this unit should be performed on a - per hours of operation - basis. The running time meter on the control panel should be used to determine the Generator Set operating time. 3-7. PMCS FOR UNITS IN CONTINUOUS OPERATION. For PMCS performed on an operating time basis, perform PMCS as close as possible to the time intervals indicated. For units in continuous operation, perform PMCS before starting operation if continuous operation will extend service interval past that which is shown. 3-8. PREVENTIVE MAINTENANCE CHECKS AND SERVICES. Table 3-2 contains a tabulated listing of PMCS which shall be performed by the Operator personnel. The item numbers are listed consecutively and indicate the sequence of minimum requirements. NOTE Leakage definitions for operator/crew PMCS shall be classified as follows: Class I Class II Class III Seepage of fluid (as indicated by wetness or dis- coloration) not great enough to form drops. Leakage of fluid great enough to form drops but not enough to cause drops to drip from item being checked/inspected. Leakage of fluid great enough to form drops that fall from the item-being checked/inspected. Equipment operation is allowable with minor leakages (Class I or II). Of course, you must consider the fluid capacity in the item/system being checked/inspected. When in doubt, notify your supervisor. When operating with Class I or Class II leaks, continue to check fluid levels as required. Table 3-2. Operator/Crew Preventive Maintenance Checks and Services NOTE Within designated interval, these checks are to be performed in the order listed. 3-4 Change 5
