SPECIAL INSTRUCTIONS - CONTINUED
4. Electric wires and connectors: Look for cracked or broken insulation, bare wires,
and loose or broken connectors. Tighten loose connections and make sure the wires
are in good condition.
5. Hoses and fluid lines: Look for wear, damage, and leaks. Make sure clamps 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
(refer to appendix B, MAC).
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 and remember - when in
doubt, notify your supervisor.
Leakage Definitions for Organizational PMCS
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 Ill
Leakage of fluid great enough to form drops that fall from the item
being checked/inspected.
CAUTION
When operating with class I or II leaks, continue to check fluid levels in addition to
that required in PMCS. Parts without fluid will stop working and/or cause damage to
the parts.
NOTE
Equipment operation is allowable with minor leakage (class I or II). Consideration
must be given to the fluid capacity in the item being checked/inspected. When in
doubt, notify your supervisor.
