When you do your PMCS, you will always need a rag or two. Following are checks that are common to the
container delivery system.
(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 (SD-2) on all metal surfaces. Use soap and water
when you clean rubber or plastic material. Upholstery can be cleaned with soap and water and a clean,
damp cloth.
(2) Rust and Corrosion. Check equipment 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 all 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 parts are welded together. If you find a bad
weld, report it to your supervisor.
(5) Electric Wires and Connectors. Look for cracked, frayed, or broken insulation, bare wires, and loose or
broken connectors. Tighten loose connectors. Report any damaged wires to your supervisor.

When you check for “operating condition”you look at the component to see if Its serviceable.
