WARNING
Dry cleaning solvent wed 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 personal injury or death.
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 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.
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.
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.
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.
