GENERAL PMCS PROCEDURES - CONTINUED

WARNING

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.

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 0019 00) on all metal surfaces. Use detergent (Item 3, WP

0019 00) and water when you clean rubber, plastic and painted surfaces.

WARNING

When servicing this machine, performing maintenance or disposing of materials such as engine coolant,

hydraulic fluid, lubricants, battery acids or batteries and CARC paint, consult your unit/local hazardous

waste disposal center or safety office for local regulatory guidance. If further 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 0019 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 connectors.

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 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.

CAUTION

Operation is allowable with Class I and Class II leakage, EXCEPT for fuel, where NO leaks are allowed.

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 vehicle and/or components.
