2-2.4.3 Routine Inspections. Use the following information to help identify potential problems before and
during checks and services.
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 could result in severe injury to personnel or death.
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.
c. 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 of 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 of 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 serviceability. If deficiencies are found, report
them to unit 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 unit level of maintenance.
2-2.5 Leakage Definitions. You must know how fluid leakage affects the status of your equipment.
The following are definitions of the types/classes of leakage you need to know to be able to determine the
status of your equipment. Learn and be familiar with them. When in doubt, notify your supervisor.
Class Leakage Definition
Class I Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
Class II Leakage of fluid great enough to form drops, but not enough to cause drops to drip from the
item being checked/inspected.
Class III Leakage of fluid great enough to form drops that fall from the item being checked/inspected.
