(a) Rust and Corrosion. Check pump body and frame for rust and corrosion, If any bare metal
or corrosion exists, clean, and apply a thin coat of oil.
(b) 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.
(c) Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together.
(d) Electric Wires and Connectors, Look for cracked, frayed, or broken insulation, bare wires,
and loose or broken connectors. Tighten loose connectors.
(e) Hoses and Fluid Lines. Look for wear, damage, and leaks, and make sure clamps and fittings
are tight. Wet spots show leaks, 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.
g. When you check for “operating condition,” you look at the component to see if it’s serviceable.
