This section contains PMCS requirements for the trailer. The PMCS table contains checks and services necessary to

4-7. GENERAL MAINTENANCE PROCEDURES.
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.
a. Cleanliness. Dirt, grease, oil and debris only get in the way and may cover up a serious problem. Use
drycleaning solvent P-D-680 (Item 22, Appendix E) on all metal surfaces. For general exterior cleaning use soap
solution (Item 21, Appendix E) and water.
b. Bolts, Nuts and Screws. Check bolts, nuts and screws for obvious looseness, missing, bent, or broken
condition. Look for loose or chipped paint, bare metal or rust around bolt heads. If any part seems loose, tighten it. If
the part is missing, bent or broken, report it to the supervisor.
