4-9. UNIT PMCS PROCEDURES.
a. Always perform your preventive maintenance in the same order, so it gets to be a habit. Once you have
some practice, you will spot anything wrong in a hurry.
If something looks wrong and you can not fix it, write it down on DA Form 2404.
Drycleaning Solvent (P-D-680) is TOXIC and flammable. Wear protective goggles, face
shield, and gloves; use only in a 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 II Drycleaning Solvent is 140 degrees F (60 degrees C)
and Type III Drycleaning Solvent is 200 degrees F (93 degrees C). 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.
c. Clean as you work and as needed. Dirt, grease, oil and debris may get in the way and cover up a problem. Use
drycleaning solvent (Item 14, Appendix E) to clean flatrack where dirt, grease, or oil has accumulated.
d. Check for missing, loose, bent or broken bolts, nuts and screws. Look for chipped paint, bare metal, or rust
around bolt heads. Tighten loose parts.
e. Look for loose paint, rust, or gaps where parts are welded together. If you find a bad weld, report it to Direct
