PMCS PROCEDURES (Con’t).
(1)
Keep It Clean. Dirt, grease, oil, and debris may cover up a serious problem. Clean as you work and as
needed. Use dry cleaning solvent (item 5, Appendix E) on all metal surfaces. Use detergent (item 4,
Appendix E) and water on rubber, plastic, and painted surfaces.
(2)
Rust and Corrosion. Check trailer body and frame for rust and corrosion. If any bare metal or corrosion
exists, clean and apply a thin coat of light oil.
(3)
Bolts, Nuts, and Screws. Ensure that none are loose, missing, bent, or broken. Tighten any that are
loose.
(4)
Welds. Look for loose or chipped paint, rust, or cracks where parts are welded together. If you find a
bad weld, notify DS maintenance.
(5)
Wiring Harness, Wires, and Connectors. Inspect for cracked or broken insulation, bare wires, and loose
or broken connectors. Tighten loose connectors. Replace as required.
(6)
Hydraulic Brake Lines, Hoses, and Fittings. Inspect for wear, damage, and leaks. Ensure that fittings
are tight. If a leak originates from a loose fitting, tighten it. If a component is broken or worn, correct
problem.
