f. If anything looks wrong and you can’t fix it, write it on your DA Form 2404. IMMEDIATELY report
it to your supervisor.
g. When you do your PMCS, you will always need a rag or two. Following are checks that are common
to the FAWPSS:
(1) Keep It Clean. Dirt, grease, oil, and debris only get in the way and may cover up a serious prob-
lem. Clean as you work and as needed. Use dry cleaning solvent (SD-2) on all metal surfaces. Use soap and
water when you clean rubber or plastic material. Upholstery can be cleaned with soap and water and a clean,
damp cloth.
(2) Bolts, Nuts, and Screws. Check them all for obvious looseness, missing, bent, or broken
condition. You can’t try them all with a tool, but look for chipped paint, bare metal, or rust around bolt heads.
If you find a bolt, nut, or screw you think is loose, tighten it or report it to your supervisor.
(3) Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you
find a bad weld, report it to your supervisor.
(4) Electric Wires and Connectors, Look for cracked, frayed, or broken insulation, bare wires, and
loose or broken connectors. Tighten loose connectors. Report any damaged wires to your supervisor.
(5) Hoses and Fluid Lines. Look for wear, damage, and leaks, and make sure clamps and fittings
are tight. Wet spots show leaks, 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, report it to your supervisor.
h. When you check for “operating condition,” you look at the component to see if it’s serviceable.
2-4.1 SPECIAL lNSTRUCTIONS. If the equipment must be kept in continuous operation, chaeck aand ser-
vice only those items that can be checked and seerviced without disturbing operation. Make complete checks
and services when equipment can be shutdown.
2-4.2 LEAKAGE DEFINITIONS FOR OPERATOR PMCS. It is necessary for you to know how fluid leakage
affects the status of the truck. Following are types/classes of leakage an operator needs to know to be able
to determine the status of the truck. Learn these leakage definitions and remember-when in doubt, notify
your supervisor.
When cleaning underhood areas, engine must be COLD (same temperature as out-
side air). DO NOT point water or steam directly at any electrical connection. DO
NOT point water stream directly at radiator fins. DO NOT use high pressure water
supply system. Damage to engine, electrical system, and other components may
result.
Equipment operation is allowable with minor leakages (Class I or II). Of course, consider-
ation must be given to fluid capacity in the item/system being checked/inspected. When in
doubt, notify your supervisor.
When operating with Class I or II leaks, continue to check fluid levels as required in your
PMCS.
Class III leaks should be reported immediately to your supervisor.
