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 precaution can cause injury
to personnel or damage to equipment.
CAUTION
Keep cleaning solvents, gasoline, and lubricants away from rubber or soft
plastic parts. They will deteriorate material.
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.
Use soap and water to clean rubber or plastic parts and material.
Check all bolts, nuts, and screws to make sure they are not loose, missing, bent, or broken. DO
not try to check them all with a tool, but look for chipped paint, bare metal, or rust around bolt
heads. If you find one loose, tighten it or report it to unit level maintenance.
Inspect welds. Look for loose or chipped paint, rust, or gaps where parts are welded together.
If a broken weld is found, report it to unit level maintenance.
Inspect electrical wires, connectors, terminals, and receptacles. Look for cracked or broken
insulation, bare wires, and loose or broken connectors. Tighten loose connectors and make sure
wires are in good condition. Examine terminals and receptacles for service ability. If deficien-
cies are found, report them to unit level maintenance.
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 unit level
maintenance.
