TM 10-3930-671-24 (4) Hydraulic  systems  (other  than  brake  systems)  may  have  class  III  leakage  and  not  be  cause  for  deadlining. Components,  such  as  actuating  cylinders,  are  designed  to  allow  a  certain  amount  of  fluid  to  pass  by  the  ram  seal  to lubricate  the  seal  and  ram.    This  could  be  interpreted  as  a  class  III  leak.    The  decision  as  to  whether  or  not  the  truck should be deadlined is based upon good mechanical knowledge and common sense. (5) Corrosion prevention and control (CPC).  It is important that any corrosion problem with this truck be reported so that  the  problem  can  be  corrected  and  improvements  can  be  made  to  prevent  the  problem  in  other  trucks.    Corrosion should   be   reported   using   Standard   Form   368,   Product   Quality   Deficiency   Report   (QDR).      Use   keywords   such   as corrosion, rust, deterioration, or cracking to ensure that the information is identified as a CPC problem.  Send Std Form 368 to Commander, U.S.  Army TACOM, Attn:  AMSTA-QRD, Warren, Ml 48397-5000. • Dry cleaning solvent (P-D-680) is TOXIC and flammable.  Wear protective goggles 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 of flame.  Never smoke when using solvent; the flash point for type I dry cleaning solvent is 100°F (380C) and for type II is 140°F (600C). 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. b. Cleanliness.  Dirt, grease, oil, and debris can cover and hide serious problems.  Use dry cleaning solvent on all metal surfaces. c. 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, tighten. d. Welds.  Look for loose or chipped paint, rust, or gaps where parts are welded together.  If bad welds are found, notify direct support maintenance. e. 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  connectors  are  found, replace as necessary. f. 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, tighten it. g. Damage is defined as:  any conditions that affect safety or render the truck unusable for mission requirements. h. Always perform PMCS in the same order until it becomes a habit.  Once practiced, it will be easy to spot anything wrong. 3-7
