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 maintenance.
f. 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.

WARNING
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 use near open flame or excessive heat.
Failure to observe this warning can cause severe
injury to personnel or DEATH.

away from rubber or soft plastic parts. They will
deteriorate material.
