(PMCS) INTRODUCTION - CONTINUED
GENERAL PMCS PROCEDURES - CONTINUED
WARN I N G
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low toxic mate-
rial. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in well-venti-
lated areas. Keep away from open flames and other sources of ignition. Failure to follow this warning may
cause injury or death to personnel.
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 (Item 2, WP 0031 00) on all metal surfaces. Use detergent (Item 4,
WP 0031 00) and water when you clean rubber, plastic, and painted surfaces.
WARN I N G
When servicing this machine, performing maintenance or disposing of materials such as engine coolant,
hydraulic fluid, lubricants, battery acids or batteries, windshield cleaning compound, and CARC paint,
consult your unit/local hazardous waste disposal center or safety office for local regulatory guidance. If fur-
ther information is needed, please contact The Army Environmental Hotline at 1-800-872-3845.
Hazardous Waste Disposal. Ensure all spills are cleaned up and disposed of IAW 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 (Item 9, WP 0031 00). Report it to your supervisor.
Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness, 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
is loose, notify your supervisor.
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 connec-
tors. Reconnect loose connectors. Ensure that wires are in good condition.
Hoses and Fluid Lines. Look for wear, damage, and signs of leaks. Check for loose clamps and fittings. 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, notify your supervisor. 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 machine. The follow-
ing 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.
