OPERATOR PREVENTIVE MAINTENANCE CHECKS AND
SERVICES (PMCS) INTRODUCTION - CONTINUED
GENERAL PMCS PROCEDURES - CONTINUED
Cleaning compound, solvent 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-ven-
tilated 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 cleaning compound, solvent (Item 3, WP 0029 00) on all metal surfaces. Use detergent (Item 5, WP
0029 00) and water when you clean rubber, plastic and painted
When servicing roller, performing maintenance or disposing of materials such as engine coolant, hydraulic
fluid, lubricants, battery acids or batteries and CARC paint, consult your Field/local hazardous waste dis-
posal 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 13, WP 0029 00). Report it to 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,
Welds. Look for loose or chipped paint, rust or gaps where parts are welded together. If you find a bad weld, report it
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 supervisor. If something is broken or worn out, report it to supervisor.
Fluid Leakage. It is necessary for you to know how fluid leakage affects the status of the roller. The following are
definitions of the types/classes of leakage you need to know to be able to determine the status of the roller. Learn and
be familiar with them, and remember - when in doubt, notify supervisor.
Operation is allowable with Class I and Class II leakage, EXCEPT for fuel, where NO leaks are allowed.
WHEN IN DOUBT, NOTIFY SUPERVISOR. When operating with Class I or Class II leaks, check fluid
levels more frequently. Class III leaks must be reported immediately to supervisor. Failure to do this will
result in damage to roller and/or components.
