TM 5-3895-373-10 SECTION II.  PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) 2.3 GENERAL. Preventive  Maintenance  Checks  and  Services  (PMCS) means  systematic  caring,  inspecting,  and  servicing   of equipment   to   keep   it   in   good   condition   and   prevent breakdowns.  The operator’s mission is to: a. Be sure to perform PMCS each time the paving machine  is  operated.    Always  do  PMCS  in  the same  order  so  that  it  becomes  a  habit.    With some practice, anything wrong is quickly spotted. b. Do   BEFORE   PMCS   just   before   operating   the paving  machine.    Pay  attention  to  WARNINGs CAUTIONs, and NOTEs. c. Do  DURING  PMCS  while  operating  the  paving machine.  During operation means to  check  the paving    machine    and    its    related    components while  it  is  actually  operating.    Pay  attention  to WARNINGs, CAUTIONs, and NOTEs. d. Do    AFTER    PMCS    right    after    operating    the paving  machine.    Pay  attention  to  WARNINGs, CAUTIONs, and NOTEs. e. Do WEEKLY PMCS once a week. f. Use  DA  Form  2404  (Equipment  Inspection  and Maintenance   Worksheet)   to   record   any   faults discovered before, during, or after operation that cannot   be   immediately   fixed.      Do   not   record faults that are immediately fixed. g. Be prepared to assist organizational maintenance   during   lubrication   of   the   paving machine.  Perform other services when required by organizational maintenance. 2.4 CLEANING AGENTS. WARNING Do  not  use  diesel  fuel,  gasoline,  or benzene (benzol) for general cleaning procedures.  Diesel fuel washdown is only permitted for general cleaning of the machine using the fuel washdown system    provided    with    the    paving machine. WARNING 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   or   flame.      Never   smoke   when using solvent; the flashpoint for Type Mil   cleaning   solvent   is   200°F   (93, 3°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,  flush  eyes  with  water and get immediate medical attention. CAUTION When  using  steam  to  clean,  do  not point  water  or  steam  directly  at  any electrical connections.  Do not use a high  pressure  steam  supply  system. Damage    to    electrical    system    and other components may occur. The  machine  should  be  cleaned  immediately  after  use. Any   asphalt   materials   or   residue   should   be   removed from   the   surfaces   of   the   machine   as   a   general   care practice.   A  fuel  spray  washdown  procedure  is  provided in  the  maintenance  section  of  this  manual.    Use  this procedure   immediately   after   completing   each   paving operation.  General cleaning procedures are as follows: a. Steam Cleaning. (1)   The paving machine may be steam cleaned if extremely dirty.  When cleaning the engine compartment, cover the alternator, air cleaner     cap     assembly,     and     any     other electronic component with waterproof material. (2)   After cleaning allow engine to air dry.  Do not use  compressed  air  to  dry  engine.    Do  not run engine to decrease drying time. (3) When   dry   remove   all   component   covers before starting engine. 2-10
