Dry cleaning solvent used to clean parts is potentially dangerous to personnel and property.
Clean parts in a well-ventilated area. Avoid inhalation of solvent fumes. Wear goggles and
rubber gloves to protect eyes and skin. Wash exposed skin thoroughly. Do not smoke or

personal injury or death.

a. Keep it clean. Dirt, grease, and oil get in the way and may cover up a serious problem. Use dry
cleaning solvent to clean metal surfaces.
b. Use soap and water to clean rubber or plastic parts and material.
c. Check all bolts, nuts, and screws to make sure they are not loose, missing, bent, or broken. Do
not try to check them with a tool, but look for chipped paint, bare metal, or rust around bolt
heads. If you find one loose, report it to the next higher level of maintenance.
d. Inspect welds for loose or chipped paint, rust, or gaps where parts are welded together. If a
broken weld is found, report it to the next higher level of maintenance.
e. Inspect electrical wires, connectors, terminals, and receptacles for cracked or broken insulation,
bare wires, and loose or broken connectors. Tighten loose connectors. Examine terminals and
receptacles for serviceability. If deficiencies are found, report them to the next higher level of
Inspect hoses and fluid lines. Look for wear, damage, and leaks. Make sure that clamps and
fittings are tight. Wet spots and stains around a fitting or connector can mean a leak. If a leak
comes from a loose connector, or if something is broken or worn out, report it to the next higher
level of maintenance.
