10. If anything looks wrong and you can't fix it, write it on your DA Form 2404. The
number column is the source for the numbers used on the TM Number Column on DA Form
2404. If you find something seriously wrong, report it to organizational maintenance
RIGHT NOW.
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).
11. 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
Seepage of fluid (as indicated by wetness or discoloration) not great
Class I
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.
Leakage of fluid great enough to form drops that fall from the item
Class III
being checked/inspected.
CAUTION
Equipment operation is allowable with minor leakages (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 11
leaks, continue to check fluid levels as required on your PMCS. Class III
leaks should be reported to your supervisor or Organizational Maintenance.
