SECTION III. UNIT PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
4-5. INTRODUCTION. To ensure the tank and pump unit is ready for operation at all times, it must be
inspected systematically so that defects may be discovered, and corrected before they result in serious damage
or failure. The necessary preventive maintenance checks and services are listed in Table 4-1. Defects
discovered during operation of the system shall be noted for future correction to be made as soon as operation

equipment. Report any deficiencies using the proper forms (See DA Pam 738-750).
