SPECIAL INSTRUCTIONS - Continued
Keep It Clean. Dirt, grease, oil and debris only get in the way and may cover up a serious problem. Clean as
you work and as needed. Use dry cleaning solvent PD-680 on all metal surfaces. Use soap and water when
you clean rubber or plastic material.
Bolts, Nuts, and Screws. Check that they are not loose, missing, bent, or broken. You can’t try them all with a
tool, of course, but look for chipped paint, bare metal, or rust around boltheads. Tighten any that you find
loose.
Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a bad weld,
report it to Direct Support Maintenance.
Electrical Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or broken con-
nectors. Tighten loose connectors and make sure the wires are in good condition.
Hoses and Fluid Lines. Look for wear, damage, and leaks. Make sure cIamps and fittings are tight. Wet spots
show leaks, of course, but a stain around a fitting or connector can also mean a leak. If a leak comes from a
loose fitting or connector, tighten it. If something is broken or worn out, either correct it or report it to Direct
Support Maintenance (see MAC, Appendix B).
LEAKAGE DEFINITIONS
It is necessary for you to know how fluid leaks affect 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.
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/in-
spected.
Class Ill
Leakage of fluid great enough to form drops that fall from
the item being checked/inspected.
