2-4. PMCS PROCEDURES.
a. Your Preventive Maintenance Checks and Services, Table 2-1, lists inspections and care to keep your air
compressor unit in good operating condition. It is set up so you can make your BEFORE (B) Operation checks as you
perform a general examination of the air compressor unit.
b. The "ITEM NO." column of Table 2-1 is the numerical sequence in which the PMCS must be performed. When
completing DA Form 2404, include the item number for the check/service indicating fault.
c.
The "INTERVAL" column of Table 2-1 tells you when to do a certain check or service.
d.
The "LOCATION, ITEM TO CHECK/SERVICE" column of Table 2-1 provides the location of the item to be
checked or serviced.
e.
The "PROCEDURE" column of Table 2-1 tells you how to do required checks and services. Carefully follow
these instructions. If you do not have tools or if the procedure tells you to, notify your supervisor.
NOTE
Terms "ready/available" and "mission capable" refer to the same status: Equipment is on hand and ready
to perform combat missions. (See DA PAM 738-750.)
f.
The "NOT MISSION CAPABLE IF:" column in Table 2-1 tells you when your air compressor unit is not capable
and why the air compressor unit cannot be used.
g.
If the air compressor unit does not perform as required, refer to Section III, Operator Troubleshooting.
h.
If anything looks wrong and you can't fix it, write it on your DA Form 2404 IMMEDIATELY and report it to your
supervisor.
i. When you do your PMCS, you will always need a rag or two. The following items are common to all of the air
compressor unit components:
(1) Keep It Clean. Dirt, grease, oil, and debris only get in the way and may cover up a serious problem.
Clean as you work and as needed. Use dry cleaning solvent (Appendix E, Item 3) on all metal surfaces. Use soap
(Appendix E, Item 5) when you clean rubber or plastic material.
(2) Rust and Corrosion. Check the components of the air compressor unit for rust and corrosion. If any bare
metal or corrosion exists, clean and apply a thin coat of oil. Report it to your supervisor.
(3) Bolts, Nuts, and Screws. Check them for obvious looseness, missing, bent, or broken condition. You
can't try them all with a tool, but look for chipped paint, bare metal, or rust around bolt heads. If you find a bolt, nut, or
screw you think is loose, tighten it or report it to your supervisor.
(4) Welds. Look for loose or chipped paint, rust, or gaps where metal parts are welded together. If you find a
bad weld, report it to your supervisor.
