GENERAL PMCS PROCEDURES CONTINUED
4. Always perform PMCS in the same order so it gets to be a habit. Once you have had some practice, you will
spot anything wrong in a hurry. If the equipment does not perform as required, refer to the appropriate trouble-
shooting procedure in Chapter 3.
5. If anything looks wrong and you cannot fix it, write it on your DA Form 2404 or DA Form 5988-E. If you find
something seriously wrong, IMMEDIATELY report it to your supervisor.
6. Before performing PMCS, read all the checks required for the applicable interval and prepare all that is needed
to make all the checks. You will always need a Rag, wiping (WP 0022, Item 16) or two.
WARN I N G
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and
low-toxic material. However, it may be irritating to the eyes and skin. Use protective gloves
and goggles. Use in well-ventilated areas. Keep away from open flames and other
sources of ignition. When not using MIL-PRF-680 solvents, ensure MIL-PRF-680 solvent
container is sealed. Store, handle and dispose of unused and spent solvents in
accordance with local procedures and plans. Failure to follow this warning may result in
injury or death to personnel.
C AU T I O N
Be especially careful when cleaning electrical system components including lighting.
Damage or impaired operation could result if this caution is not observed.
a. Keep Equipment Clean. Dirt, grease, oil, and debris may cover up a serious problem. Clean as you work
and as needed. Use Cleaning compound, solvent, type III (WP 0022, Item 2) on all metal surfaces. Use
Detergent, general purpose, liquid (WP 0022, Item 4) and water when you clean rubber, plastic, and
painted surfaces. Spot paint as required to prevent corrosion.
b. Hazardous Waste Disposal. Ensure all spills are cleaned up and disposed of IAW local policy and
ordinances.
c.
Rust and Corrosion. Check metal parts for rust and corrosion. If any bare metal or corrosion exists, clean
and apply light coating of Oil, lubricating, OE/HDO 30 (WP 0022, Item 11), corrosion inhibitor, and notify
Field Maintenance.
d. Bolts, Nuts, and Screws. Ensure that they are not loose, missing, bent, or broken. Report loose, missing,
or damaged bolts, nuts, and screws to Field Maintenance.
e. Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. Report bad welds
to Field Maintenance.
f.
Electrical Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or broken
connectors. Report loose connections and faulty wiring to Field Maintenance.
g. Hoses, Lines, and Fittings. Look for wear and damage. Check for loose clamps and fittings. Report any
worn, damaged, or loose hoses, lines, and fittings to Field Maintenance.
h. 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, or classes, of leaks you need to know to determine the status of your
machine. Learn and be familiar with them, and remember when in doubt, notify Field Maintenance.
C AU T I O N
EXCEPT FOR ANY TYPE OF FUEL OR COOLANT LEAK, operation is allowable with
Class I and Class II leakage. WHEN IN DOUBT, NOTIFY FIELD MAINTENANCE. When
operating with Class I or Class II leaks, check fluid levels more frequently. Any type of fuel
or coolant leak, or any Class III leak, must be reported immediately to Field Maintenance.
Failure to do this will result in damage to machine and/or components.
