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.
(6)
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. If something is broken or worn out, report it to your
supervisor.
