WARNING
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 or death.
CAUTION
Keep cleaning solvents, gasoline and lubricants away from rubber or
soft plastic parts. They will deteriorate material.
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 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.
d.
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.
e.
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.
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 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.
Leakage
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.
2-2.6 Order in Which PMCS will be done. Figure 2-1 shows the order in which you are to perform your PMCS. The
figure shows a generator to which a kit has been added. The number call outs on Figure 2-1 corresponds to the numbers
in the Item No. column of Table 2-1, for BEFORE/DURING PMCS.
