Section III. UNIT PREVENTIVE MAINTENANCE CHECKS AND SERVICES
To insure the tank unit 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.
b. The necessary preventive maintenance checks and services to be performed by unit maintenance per-
sonnel are listed in Table 4-1 and described in Chapter 4, Section V.
Defects discovered during operation of the unit will be noted on DA Form 2404 for future corrections
to be made as soon as operation has ceased. Stop operation immediately if a deficiency is noted which would dam-
age the equipment if operation were continued.
d. Record all deficiencies, shortcomings and the corrective action taken, on DA form 2404 (Equipment In-
spection and Maintenance Worksheet) at the earliest possible opportunity.
