TM 10-3930-653-14&P ORGANIZATIONAL PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) GENERAL To make sure that your vehicle 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  table  on  the  next  pages  contain  your organizational PMCS.  The item numbers indicate the sequence of minimum inspection requirements.  If you’re operating the  vehicle  and  notice  something  wrong  which  could  damage  the  equipment  if  you  continue  operation,  stop  operation immediately. 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. ORGANIZATIONAL PREVENTIVE MAINTENANCE CHECKS AND SERVICES 1. The item numbers of the table indicate the sequence of the PMCS.  Perform at the intervals shown below. a. Do your (A) PREVENTIVE MAINTENANCE annually (once every year). b. Do your (H) PREVENTIVE MAINTENANCE at the hour interval listed. 2. If something  does not work, troubleshoot it according to the instructions in this manual or notify your supervisor. 3. Always do your preventive maintenance in the same order so it gets to be a habit.  Once you’ve had some practice, you will spot anything wrong in a hurry. 4. If anything looks wrong and you can not fix it, write it down on your DA Form 2404.  If you find something seriously wrong, report it to direct support as soon as possible.
