SERVICES (PMCS) (Contd)
e. Troublespots
WARNIN G
Drycleaning fluid is flammable and will not be used near open
flame. A fire extinguisher will be kept nearby when solvent is
used. Use only in well-ventilated places. Failure to do this may
result in injury or death to personnel.
NOTE
Dirt, grease, oil, and debris may cover up a serious problem.
Clean as you check. Follow precautions printed on container.
Use drycleaning solvent on all metal surfaces. Use soap and
water on rubber or plastic material.
(1)
Check all bolts, nuts, and screws. If loose, bent, broken, or missing, either
tighten or report conditions to your supervisor.
(2)
Look for loose or chipped paint, rust, and gaps at welds. If a cracked or
broken weld is found, report condition to your supervisor.
(3)
Inspect electrical wires and connectors for cracked or broken insulation. Look
for bare wires and loose or broken connections. Tighten loose connections. If insulation
is cracked or broken, wires bare, or broken connections, report to your supervisor.
(4)
Check hoses and fluid lines for wear, damage, and leaks. Make sure
clamps and fittings are tight. (Refer to para. 2-11 for information on leaks.)
f. Correct Assembly or Stowage.
Check each component or assembly for
installation in the right place and with no missing parts.
2-11. CLASS LEAKAGE DEFINITIONS
Wetness around seals, gaskets, fittings, or connections indicates leakage. A stain
also denotes leakage. If a fitting or connector is loose, tighten it. If broken or
defective, report it. Use the following as a guide:
a. Class I.
Leakage indicated by wetness or discoloration not great enough to
form drops.
b. Class II.
Leakage great enough to form drops but not enough to cause drops
to drip from item being checked/inspected.
c. Class III.
Leakage great enough to form drops that fall from the item being
checked/inspected.
WARNIN G
Hearing protection is required for driver, co-driver, and mechanic
when engine is running. Noise levels produced by vehicle exceed 85
dB, which may cause injury to personnel.
CAUTION
Operation is allowable with a class I or II leakage. You must
consider fluid capacity of the item/system. WHEN IN DOUBT,
NOTIFY YOUR SUPERVISOR. When operating with class I or II
leaks, check fluid levels more frequently. Class III leaks must be
immediately reported to your supervisor.
