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
has ceased. Stop operation immediately if a deficiency is noted during operation, which would damage the
equipment if operation were continued. If the equipment fails to operate, troubleshoot with the proper
equipment. Report any deficiencies using the proper forms (See DA Pam 738-750).
