Purpose of PMCS Table. The purpose of the PMCS table is to provide a systematic method of
inspecting and servicing the equipment. In this way, small defects can be detected early before they
become a major problem causing the equipment to fail to complete its mission. The PMCS table is
arranged with the individual PMCS procedures listed in sequence under assigned intervals. The most
logical time (before, during, or after operation) to perform each procedure determines the interval to
which it is assigned. Make a habit of doing the checks and services in the same order each time and
anything wrong will be seen quickly. See paragraph 3-7 for an explanation of the columns in
3-7. Explanation of Columns. The following is a list of the PMCS table column headings with a
description of the information found in each column.
a. Item No. This column shows the sequence in which the checks and services are to be
performed, and is used to identify the equipment area on the Equipment Inspection and Maintenance
Worksheet, DA Form 2404.
b. Interval. This column shows when each check is to be done.
c. Item to be Inspected/Procedures. This column identifies the general area or specific part
where the check or service is to be done, and the checks or services to be done, and explains how to
d. Equipment is Not Ready/Availab If. This column lists conditions that make the equipment
unavailable for use because it is unable to perform its mission or because it would represent a safety
hazard. Do not accept or operate equipment with a condition in the Equipment is Not Ready/Available
Reporting Deficiencies. If you discover any problem with the equipment during PMCS or while
operating it that you are unable to correct, it must be reported. Refer to DA Pam 738-750 and report
the deficiency using the proper forms.
3-9. Special Instructions. Preventive maintenance is not limited to performing the checks and
services listed in the PMCS table. Covering unused receptacles, stowing unused equipment and other
routine procedures such as equipment inventory, cleaning components, and touch-up painting are
not listed in the PMCS table. These are things you should do any time you see they need to be done. If
a routine check is listed in the PMCS table it is because other operators have reported problems with
this item. Take along tools and cleaning cloths needed to perform the required checks and services.
Use the information in the following paragraphs to help you identify problems at any time.
