ARMY TM 9-6115-464-12 AIR FORCE TO 35C2-3-445-1 NAVY NAVFAC P-8-624-12 Section IV. PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) NOTE The PMCS chart in this section contains all necessary unit preventive maintenance checks and services for this equipment. 4-5 INTRODUCTION. Purpose. Your PMCS table lists the checks (inspections) and services (care) of your equipment to keep it in good operat- ing condition. Inspection will allow defects to be discovered and corrected before they result in serious damage or failure. Table 4-1 lists the PMCS in sequence of performance. Unit personnel must observe all cautions and warnings. 4-6 EXPLANATION OF COLUMNS. a. Item Number column. This column provides identification numbers for the performance of PMCS func- tions in proper sequence. Use the numbers as a reference on reports of failures and deficiencies. (For Army users, report on DA Form 2404 Equipment Inspection and Maintenance Worksheet). b. Interval column. This column identifies when particular functions (checks/service) must be performed. c. Item to check/service column. This column identifies specific items for inspecting (servicing/checking). d. Procedures. This column lists the checks or services you have to perform and explains how to perform them. e. Not Mission Capable If: column. This column tells you when and why your equipment cannot be used. 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 by PMCS. Equipment damage could result if caution is not observed. NOTE The terms ready/available and mission capable refer to the same status: equip- ment is on hand and is able to perform its combat mission. NOTE Leakage definitions for unit PMCS shall be classified as follows: Class I: Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops. Class II: Leakage of fluid great enough to form drops but not enough to cause drops to drip from the item being checked/inspected. Class Ill: Leakage of fluid great enough to form drops that fall from the item being checked/inspected. 4-7 REPORTING DEFICIENCIES. If your equipment does not perform as required, and if you discover problems during PMCS that you are unable to correct, it must be reported. Refer to DA Pam 736-750 and report the deficiency using the proper forms. 4-5
