WARNING
·
Drycleaning solvent (P-D-680) is TOXIC and flammable. Wear protective goggles,
face shield, and gloves; use only in a well-ventilated area; avoid contact with skin,
eyes, and clothes; and do not breathe vapors. Keep away from heat or flame. Never
smoke when using solvent. The flashpoint for Type III Drycleaning Solvent is 200_F
(93_C). Failure to do so may result in injury or death to personnel.
·
If personnel become dizzy while using cleaning solvent, immediately get fresh air
and medical help. If solvent contacts skin or clothes, flush with cold water. If
solvent contacts eyes, immediately flush eyes with water and get immediate medical
attention.
a. Cleanliness. Dirt, grease, oil, and debris only get in the way and may cover up a serious problem.
Use drycleaning solvent (Item 18, Appendix F) on metal surfaces and soapy water on rubber.
b. Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness, missing, bent, or
broken condition and tighten or replace as necessary. If they cannot be checked with a tool, look for
chipped paint, bare metal, or rust around bolt heads.
c. Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If a bad
weld is found, notify the supervisor.
d. Electric Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or
broken connectors. Tighten loose connectors and make sure the wires are in good shape.
e. Fluid Hoses, Tubes, and Fittings. Look for wear, damage, leaks, and make sure clamps and
fittings are tight. Wet spots show leaks, but a stain around a fitting or connector may also indicate a
leak. If connector or fitting is loose, tighten it. If something is broken or worn out, repair or replace
per applicable procedure.
f. Damage. Damage is defined as any condition that affects safety or would make the truck
unserviceable for mission requirements.
