SPECIAL INSTRUCTIONS - CONTINUED
4. Electrical 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 determine the status of you
equipment. Learn them and be familiar with them. 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 III
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.
