(1) Keep it clean: Dirt,
greases 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
p l a s t i c m a t e r i a l.
(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. Tighten any that you find loose.
(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 direct support.
(4) Electric wires and connectors: Look for cracked or broken insulation, bare
wires and loose or broken connectors. Tighten loose connections and make sure that
the wires are in good condition.
(5) Hoses and fluid lines: Look for wear, d a m a g e a n d l e a k s . M a k e s u r e c l a m ps

(6) It is necessary for you to know how fluid leaks affect 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 them and be famili-
ar with them and REMEMBER - when in doubt, notify your supervisor.
