2-14. PREVENTIVE MAINTENANCE CHECKS AND SE RVICES(CONT)
Dry cleaning solvent P-D-680 used to clean parts is toxic
and flammable. Wear protective goggles and gloves and use
only in a well ventilated area. Avoid contact with skin,
eyes and clothes and dont breathe vapors. Do not use near
open flame or excessive heat and dont smoke when using it.
Failure to do so could cause serious injury. If you become
dizzy while using cleaning solvent, get fresh air and medi-
cal attention immediately. If contact with skin or clothes
is made, flush with large amounts of water. If contact with
eyes is made, wash eyes with water and get medical aid
Compressed air used for cleaning purpose will not exceed 30
psi. Use only with effective chip guarding and personal pro-
tective equipment (goggles/shield, gloves, etc). Failure to
do so could cause serious injury to eyes and possible blind-
ness. If you hurt your eyes or if a foreign object is blown
into your eyes, seek medical attention immediately.
(1) 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 sol-
vent (P-D-680) to clean metal surfaces. Use soap and water when you clean rubber or
(2) Bolts, nuts, and screws: Check that they are not loose, missing, bent or
broken. You can-t try them all with a tool of course, but look for chipped paint,
bare metal or rust around bolt heads. If you find one you think is loose, tighten
it, or report it to organizational maintenance if you can-t tighten it.
(3) Welds: Look for loose or chipped paint, rust or gaps where parts are welded
together. If you find a bad weld , report it to organizational maintenance.
(4) Electric wires and connectors: Look for cracked or broken insulation, bare
wires and loose or broken connectors. Tighten loose connectors and make sure that
the wires are in good shape.
(5) Hoses and fluid lines: Look for wear, damage and leaks. Make sure clamps
and fittings are tight. Wet spots show leaks, of course, but a stain around a fit-
ting or connector can mean a leak. If a leak comes from a loose fitting or connec-
tor, tighten it. If something is broken or worn out, report it to organizational
k. It is necessary for you to know how fluid leaks affect the status of your e-
quipment. 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 them and be famil-
iar with them and REMEMBER - when in doubt, notify your supervisor.
