a.
Routine Inspections. Use the following information to help identify potential problems before and during
checks and services
WARNING
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 100°F 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.
