Replace any hose, cable, or lead that you find damage or excessively worn. Tighten any loose fittings or plugs that are found. Inspect the electical wires to see if there are any signs of burning, heat, or acring. Inform maintenance if anything looks out of the ordinary. (Refer to page 9 and 11 of the Maintenance Guide.)
