a. 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 (P-D-680) to clean metal surfaces. Use soap and water when you clean
rubber or plastic material.
b. 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 bolt heads. Tighten any that you find loose. Report it to
organizational maintenance if you can't tighten it.
c. Welds: Look for loose or chipped paint, rust or gaps where parts are welded together. If you find a bad weld,
report it to organizational maintenance.
d. Electric wires and connectors: Look for cracked or broken insulation, bare wires and loose or broken connectors.
Report damaged or loose wiring to organizational maintenance.
e. 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 mean a leak. If a leak comes from a loose fitting or
connector, tighten it. If something is broken or worn out report it to organizational maintenance (refer to Maintenance
Allocation Chart).
f. Vehicle must be on level ground in order to get correct fluid level measurement.

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 OPERATOR/CREW 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/insp ected.
CAUTION
Equipment operation is allowable with minor leakage (Class I or II). Of course, consideration must be
given to the fluid capacity in the item/system being checked/inspected. When -operating with Class I or II
leaks, continue to check fluid levels as required on your PMCS. Class III leaks should be reported to your
supervisor or Organizational Maintenance.
