Dirt, grease, oil, and debris only get in the way and may cover up a seriousproblem. Clean as you work and as needed. Use dry cleaning solvent (SD-2) on all metal surfaces. Use soapand water when you clean rubber or plastic material. Upholstery can be cleaned with soap and water anda clean, damp cloth.Rust and Corrosion. Check pump body and frame for rust and corrosion. If any bare metal orcorrosion exists, clean, and apply a thin coat of oil. Report it to your supervisor.Bolts, Nuts, and Screws. Check them all for obvious looseness, missing, bent, or brokencondition. 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.Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If youfind a bad weld, report it to your supervisor.Electric Wires and Connectors, Look for cracked, frayed, or broken insulation, bare wires, andloose or broken connectors. Tighten loose connectors. Report any damaged wires to your supervisor.Hoses and Fluid Lines. Look for wear, damage, and leaks, and make sure clamps and fittingsare tight. Wet spots show leaks, but a stain around a fitting or connector can also mean a leak. If a leak comesfrom a loose fitting or connector, tighten it. If something is broken or worn out, report it to your supervisor.When you check for “operating condition,” you look at the component to see if it’s serviceable.2-3.
