ORGANIZATIONAL
PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
1. General
a. To make sure that your equipment is ready for operation at all times, inspect it systematically so you can discover
any defects and have them corrected before they result in serious damage or failure. The charts on the next few pages
contain your organizational PMCS. The item numbers indicate the sequence of minimum inspection requirements. If
you're operating the equipment and notice something wrong which could damage the equipment if you continue
operation, stop operation immediately.
b. Record all deficiencies and shortcomings, along with the corrective action taken, on DA Form 2404. The Item
Number column is the source for the numbers used on the TM Number column on DA Form 2404.
2. Preventive Maintenance Checks and Services
a. Do your quarterly (Q) PREVENTIVE MAINTENANCE every three months.
b. Do your semiannually (S) PREVENTIVE MAINTENANCE every six months.
c. Do your annually (A) PREVENTIVE MAINTENANCE once every year.
d. Do your biennially (B) PREVENTIVE MAINTENANCE once every two years.

f. Do your mile (M) PREVENTIVE MAINTENANCE at the mile interval listed.
g. If something doesn't work, troubleshoot it according to the instructions in this manual or notify your supervisor.
h. Always do your preventive maintenance in the same order so it gets to be a habit. Once you've had some
practice, you'll spot anything wrong in a hurry.
i. If anything looks wrong and you can't fix it, write it down on your DA Form 2404. If you find something seriously
wrong, report it to direct support maintenance RIGHT NOW.
j. When you do your PREVENTIVE MAINTENANCE, take along the tools you need to make all the checks. You
always need a rag or two.
