Section II. PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
a. Preventive Maintenance Checks and Services (PMCS), Table 3-1, are to be done to be sure the helmet is ready for
use at all times. These checks and services help you find and fix defects before the helmet is damaged or fails.
b. Item numbers in the first column on Table 3-1 are the order in which things are to be done. Column two "Interval"
lists when to do them.
c. If minor defects are found when the helmet is in use, take notes on what they are. Fix them, or have them fixed
after you have stopped using the helmet.
d. Record all defects and steps taken to fix them on DA Form 2404 (Equipment Inspection and Maintenance Work
Sheet) as soon as possible. Use of DA Form 2408-22 is also required.
Always keep in mind the WARNINGS located on the inside front cover. Perform BEFORE (B) PMCS.
