Carefully follow these instructions. Report any malfunctions or failures on DA Form 2404.
Not Fully Mission Capable if: Column. Entries in this column will be keyed specifically to checks listed in the
Procedure column for the purpose of identifying criteria that will cause equipment to be classified as not fully
mission capable because of inability to perform its primary mission. Entries in this column will:
Identify conditions that make the equipment not ready or available for use.
Deny use of equipment until corrective action has been performed. Always keep warnings and cautions in
mind as you do PMCS. Take along all tools needed and a clean cloth (Appx. C, item 5) or two to make
To Maximize Effectiveness of PMCS, Always Watch for Following Conditions:
Dirt and Grease. Keep hydraulic impact wrench clean. Dirt, grease, oil, and other debris may hide a serious
problem and will shorten the life of equipment. Clean as you work.
Dry-cleaning solvent (P-D-680) is toxic and flammable. Wear protective goggles and gloves; use
only in well ventilated area; avoid contact with skin, eyes, and clothes, and do not breathe
vapors. Keep away from heat or flame. Never smoke when using solvent; the flashpoint for type
I dry-cleaning solvent is 100 degrees Fahrenheit (oF) (37.8 degrees Celsius [oC] ) and for type II is
138oF (58.9oC). Failure to do so may result in injury or death to personnel.
If personnel become dizzy while using cleaning solvent, immediately get fresh air and medical
help. If solvent contacts skin or clothes, flush with cold water. If solvent contacts eyes,
immediately flush eyes with water and get immediate medical attention.
Use dry-cleaning solvent (Appx. C, item 16) on all metal surfaces. Use detergent (Appx. C, item 11) and water
to clean rubber or plastic materials.
Loose, Damaged, or Missing Bolts, Nuts. and Screws. Check for obvious looseness or damaged condition.
Without using a wrench, it may be difficult to spot loose hardware. However, you can often identify loose bolts
by chipped or missing paint around bolt head and bare metal at base of bolt head. If you find a loose bolt,
tighten it. If a bolt is missing or a damaged bolt, nut, or screw is discovered, it must be replaced.
Fluid Leaks. Look for wear, damage, and leaks under fluid hoses, lines, and fittings. Ensure fittings and clamps
are tight. Wet spots indicate leaks, but stains around a fitting can also mean a leak. If a leak comes from a
loose fitting or connector, tighten the connection. If a hose, fitting, or connector is broken or worn out, it must be
