Dry cleaning solvent P-D-680 is toxic and flammable. Wear protective
goggles and gloves and use only in well ventilated area. Avoid contact
with skin, eyes and clothes and dont breathe vapors. Do not use near
open flame or excessive heat. The flash point is 100° F -138° F. If you
become dizzy while using cleaning solvent, get fresh air immediately and
get medical aid. If contact with eyes is made, wash your eyes with water
and get medical aid immediately.
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.
Bolts, nuts and screws: Check that they are not loose, missing, bent or broken. You cant try
them all with a tool, of course, but look for chipped paint, bare metal or rust around bolt heads.
Tighten any bolt, nut or screw that you find loose.
Welds: Look for loose or chipped paint, rust or gaps where parts are welded together. If you
find a bad weld, report it to Direct Support Maintenance.
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.
Hoses and fluid lines: Look for wear, damage and leaks. 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
leakage comes from a loose fitting or connector, tighten the fitting or connector. If something
is broken or worn out, either correct it or report it to unit maintenance.
Vehicle must be on level ground in order to get correct fluid level measurement.
i. 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.
Class I
Class II
Class Ill
Equipment operation is allowable with minor leakages (Class I or II). Of
course, consideration must be given to 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.
Seepage of fluid (as indicated by wetness or discoloration) not great enough to form
drops.
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 being checked/inspected.
