If equipment fails to operate, refer to Section IV Troubleshooting. If the problem cannot becorrected, see paragraph 3-8, Reporting Deficiencies.

3-6. Purpose of PMCS Table. The purpose of the PMCS table is to provide a systematic method ofinspecting and servicing the equipment. In this way, small defects can be detected early before theybecome a major problem causing the equipment to fail to complete its mission. The PMCS table isarranged with the individual PMCS procedures listed in sequence under assigned intervals. The mostlogical time (before, during, or after operation) to perform each procedure determines the interval towhich it is assigned. Make a habit of doing the checks and services in the same order each time andanything wrong will be seen quickly. See paragraph 3-7 for an explanation of the columns intable 3-2.

3.7. Explanation of Columns. The following is a list of the PMCS table column headings with adescription of the information found in each column.

a. Item No. This column shows the sequence in which the checks and services are to beperformed, and is used to identify the equipment area on the Equipment Inspection and MaintenanceWorksheet, 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 partwhere the check or service is to be done, lists the checks or services to be done and explains how to dothem.

d. Equipment is Not Ready/Available If This column lists conditions that make the equipmentunavailable for use because it is unable to perform its mission or because it would represent a safetyhazard. Do not accept or operate equipment with a condition in the “Equipment is Not Ready/AvailableIf” column.

3.8. Reporting Deficiencies. If you discover any problem with the equipment during PMCS or whileoperating it that you are unable to correct, it must be reported. Refer to DA Pam 738-750 and reportthe deficiency using the proper forms.

Drycleaning solvent P-D-680 is both toxic and flammable. Wear safety gogglesand gloves and use in a well-ventilated area. Avoid prolonged breathing ofvapors and avoid skin contact. Do not use near open flame or excessive heat.Flash point of solvent is 100°F to 138°F (38°C to 59°C). If you become dizzywhile using P-D-680, get fresh air immediately and get medical aid. If P-D-680 contacts eyes, flush with water and get medical aid immediately.

Keep it clean. Dirt, grease, and oil get in the way and may cover up a serious problem.Use drycleaning solvent P-D-680, to clean metal surfaces. Use soap and water to cleanrubber or plastic parts and material.

Bolts, nuts, and screws. Check them all to make sure they’re not loose, missing, bent, orbroken. Don’t try to check them all with a tool, but look for chipped paint, bare metal, orrust around bolt heads. If you find one loose, tighten it or report it to unit maintenance.

Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together.If a broken weld is found, report it to higher level of maintenance.

Electrical wires, connectors, terminals and receptacles. Look for cracked or brokeninsulation, bare wires, and loose or broken connectors. Tighten loose connectors andmake sure the wires are in good condition. Examine terminals and receptacles forserviceability.

Hoses and fluid lines. Look for wear, damage, and leaks. Make sure clamps and fittingsare tight. Wet spots and stains around a fitting or connector can mean a leak. If a leakcomes from a loose connector, tighten it. If something is broken or worn out, report it tounit maintenance.

b. Leakage Definitions. It is necessary for you to know how fluid leakage affects the status of yourequipment. The following are definitions of the types/classes of leakage you need to know to be ableto determine the status of your equipment. Learn and be familiar with them. When in doubt, NOTIFYYOUR SUPERVISOR!

Leakage Definitions:

Class I Seepage of fluid (as indicated by wetness or discoloration) not greatenough to form drops.

Class II Leakage of fluid great enough to form drops but not enough to causedrops to drip from item being checked/inspected.

Class Ill Leakage of fluid great enough to form drops that fall from the itembeing checked/inspected.
