TM 10-3930-671 -10 3-2.  GENERAL PMCS PROCEDURES AND CONDITIONS. This section describes general procedures and conditions that should be observed when performing PMCS.  If any of the components being inspected during the PMCS procedures show any of the conditions described in this paragraph, report it on a DA 2404 form and inform unit maintenance. WARNING · Drycleaning 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 of flame.  Never smoke when using solvent; the flash point for type I drycleaning solvent if 100°F (38°C) and, for type II, is 140°F (60°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. · Personnel hearing can be PERMANENTLY DAMAGED if exposed to constant high noise levels of 85 dB (A) or greater.  Wear approved hearing protection devices when working in high noise level areas.  Personnel exposed to high noise levels shall participate in a hearing conservation program  in  accordance  with  TB  MED  501.    Hearing  loss  occurs  gradually  but  becomes permanent over time. a. Cleanliness.  Dirt, grease, oil, and debris can cover and hide serious problems.  Use drycleaning solvent on all metal surfaces. b. Bolts, Nuts, and Screws.  Check bolts, nuts, and screws for obvious looseness, missing, bent, or broken condition. Look for chipped paint, bare metal, or rust around bolt heads.  If any part seems loose, notify unit maintenance. c. Welds.  Look for loose or chipped paint, rust, or gaps where parts are welded together.  If bad welds are found, notify unit maintenance. d. Electric Wires and Connectors.  Look for cracked or broken insulation, bare wires, and loose or broken connectors. Tighten  loose  connectors  and  make  sure  wires  are  in  good  shape.    If  bad  wires  or  connector  are  found,  notify  unit maintenance. e. Hydraulic Lines and Fittings.  Look for wear, damage, and leaks, and make sure clamps and fittings are tight.  Wet spots show leaks, and a stain around a connector or fitting can mean a leak.  If a loose fitting or connector causes a leak, notify unit maintenance. f. Damage is defined as:  any conditions that affect safety or render the truck unusable for mission requirements. g. Rust and Corrosion.  Check truck body and frame for rust and corrosion.  If any bare metal or corrosion exists, clean and apply a thin coat of oil.  Report it to your supervisor. 3-2
