TM 9-6115-651-14&P
a. Routine Inspection. Use the following information to help identify potential problems before and during
checks and services.

Drycleaning solvent PD-680 is both toxic and flammable. Wear safety goggles and
gloves and use in a well-ventilated area. Avoid prolonged breathing of vapors and avoid
skin contact. Do not use near open flame or excessive heat. Flash point of solvent is
100OF to 138°F (38°C to 59°C). If you become dizzy while using PD-680, get fresh air
immediately and get medical aid. If PD-680 contacts eyes, flush with water and get
medical aid immediately.
(1)

Keep it clean. Dirt, grease, and oil get in the way and may cover up a serious problem. Use drycleaning
solvent PD-680, to clean metal surfaces. Use soap and water to clean rubber or plastic parts and
material.

(2)

Bolts, nuts, and screws. Check them all to make sure they’re not loose, missing, bent, or broken. Don’t
try to check them all with a tool, but look for chipped paint, bare metal, or rust around bolt heads. If you
find one loose, tighten it or report it to unit maintenance.

(3)

Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If a broken weld
is found, report it to higher level of maintenance.

(4)

Electrical wires connectors, terminals and receptacles. Look for cracked or broken insulation, bare
wires, and loose or broken connectors. Tighten loose connectors and make sure the wires are in good
condition. Examine terminals and receptacles for serviceability.

(5)

Hoses and fluid lines. Look for wear, damage, and leaks. Make sure clamps and fittings are tight. Wet
spots and stains around a fitting or connector can mean a leak. If a leak comes from a loose connector,
tighten it. If something is broken or worn out, report it to unit maintenance.

b. Leakage Definitions. It is necessary for you to know how fluid leakage affects 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. When in doubt, NOTIFY YOUR SUPERVISOR!
Leakage Definitions:
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 item being checked/inspected.

Class Ill

Leakage of fluid great enough to form drops that fall from the item being
checked/inspected.

3-3

TM 9-6115-651-14&P
CAUTION
Equipment operation is allowable with minor leakage (Class I or II) of any fluid except
fuel. Of course, consideration must be given to the fluid capacity in the item being
checked/inspected. When in doubt, notify your supervisor.
When operating with Class I or II leaks, continue to check fluid level more often than
required in the PMCS. Parts without fluid will stop working and/or cause equipment
damage.
Class Ill leaks should be reported to your supervisor or unit maintenance.
NOTE
If the equipment must be kept in continuous operation, check and service only those
items that can be checked and serviced without disturbing operation. Make the complete
checks and services when the equipment can be shut down.
Within designated interval, these checks are to be performed in the order listed.
