PMCS PROCEDURES (Con't).
d. Always do your PMCS 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.
e. If anything looks wrong and you can't fix it, write it on your DA Form 2404. If you find something seriously
wrong, IMMEDIATELY report it to Organizational Maintenance.
f.
When you perform PMCS, take along the tools you need to make all the checks. You'll always need a rag
(Item 12, Appendix E) or two.
WARNING
Dry cleaning solvent, P-D-680, Is toxic and flammable. Always wear protective goggles and
gloves, and use only In a well-ventilated area. Avoid contact with skin, eyes, and clothes, and DO
NOT breathe vapors. DO NOT use near open flame or excessive heat. The solvent's flash point is
100F-138F (380C-590C). If you become dizzy while using cleaning solvent, immediately get fresh
air and medical help. If solvent contacts eyes, Immediately wash your eyes and get medical aid.
(1) Keep it Clean. Dirt, grease, oil, and debris get in the way and may cover up a serious problem. Clean
as you work and as needed. Use dry cleaning solvent (Item 13, Appendix E) on all metal surfaces. Use detergent (Item 5,
Appendix E) and water when you clean rubber or plastic.
(2) Bolts, Nuts, and Screws. Check them all for obvious looseness, missing, bent, or broken condition.
You can't try them all with a tool, of course, but look for chipped paint, bare metal, or rust around bolt heads. If you find
one you think is loose, tighten it or report it to Organizational Maintenance if you can't tighten it.
(3) Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a
bad weld, report it to Organizational Maintenance.
(4) Electric Wire and Connectors. Look for cracked or broken insulation, bare wires, and loose or broken
connectors. Tighten loose connectors and make sure the wires are in good condition.
(5) Air and Hydraulic Hoses and Lines. Look for wear, damage, and signs of leaks. Ensure that clamps
and fittings are tight. Wet spots indicate leaks, of course, but a stain around a fitting or connector can also mean a leak. If
a leak comes from a loose fitting or connector, tighten it. If something is broken or worn out, report it to Organizational
Maintenance.
