GENERAL PMCS PROCEDURES - Continued
Keep It Clean. Dirt, grease, oil, and debris get in the way and may cover up a serious problem. Clean as you work
and as needed. Use solvent cleaning compound (WP 0088, Table 1, Item 4, 5, 6, 7, 8, 9) on all metal surfaces. Use
detergent (WP 0088, Table 1, Item 12) and water when you clean rubber, plastic, and painted surfaces.
Hazardous Waste Disposal. Ensure all spills are cleaned up and disposed of in accordance with local policy and
ordinances.
Rust and Corrosion. Check metal parts for rust and corrosion. If any bare metal or corrosion exists, clean and apply
a light coat of lubricating oil (WP 0088, Table 1, Item 26, 27, 28). Report it to your supervisor.
Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness and missing, bent, or broken
condition. You can't try them all with a tool, but look for chipped paint, bare metal, or rust around bolt heads. If you
find one you think is loose, tighten it.
Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a bad weld, report
it to your supervisor.
Electric Wires and Connectors.Look for cracked or broken insulation, bare wires, and loose or broken connectors.
Tighten loose connectors and ensure that the wires are in good condition.
Hoses and Fluid Lines. Look for wear, damage, and signs of leaks. Ensure that clamps and fittings are tight. Wet
spots indicate leaks, but a stain around a fitting or connector can also mean a leak. If a leak comes from a loose
fitting or connector, tighten it. If something is broken or worn out, report it to your supervisor.
Fluid Leakage. 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 machine.
Learn and be familiar with them, and remember - when in doubt, notify your supervisor.
NOTE
Operation is allowable with Class I and Class II leakage. WHEN IN DOUBT, NOTIFY
YOUR SUPERVISOR.
When operating with Class I or Class II leaks, check fluid levels more frequently. Class
III leaks must be reported immediately to your supervisor. Failure to do this will result in
damage to machine and/or components.
Notify Field Maintenance of any leaks the operator cannot fix.

LUBRICATION PROCEDURES
Included in this PMCS are lubrication services to be performed by the operator.
Keep all lubricants in an environmental storage container and store in a clean, dry place away from extreme heat.
Keep container covers clean and do not allow dust, dirt, or other foreign material to mix with lubricants. Keep
lubrication equipment clean and ready for use. Clean top of container before opening.
