TM 5-3895-373-10 b. Cleaning   Rust   or    Grease.        When      cleaning grease buildup or rusted areas, use cleaning solvent and a   stiff   bristle   brush;   do   not   use   a   wire   brush.      After cleaning  wipe  surfaces  with  a  clean  rag  until  all  dirt  or grease is removed.  Apply a light coat of oil to any bare metal surfaces to prevent additional rusting. 2.5 LUBRICANTS. All    lubrication    of    the    paving    machine    shall    be    in accordance with LO 5-3895-373-12 Lubrication Order. 2.6 FLUID LEAKAGE. It  is  necessary  to  know  how  fluid  leakage  affects  the status of the paving machine. Following are types/classes   of   leakage   an   operator   must   know   to determine the status of the paving machine.  Learn these leakage definitions; when in doubt notify the supervisor. NOTE Equipment     operation     is     allowable with   minor   leakages   (Class   I   or   II). Consideration  must  be  given  to  fluid capacity in the item/system checked/inspected.    When  in  doubt, notify the supervisor. When   operating   with   Class   I   or   II leaks,  continue  to  check  fluid  levels as required by PMCS. Immediately   report   Class   m      leaks, fuel leaks, and steady stream leaks of hydraulic fluid to the supervisor. a. Class   I.      Seepage   of   fluid   (as   indicated   by wetness   or   discoloration)   not   great   enough   to   form drops. b. Class II.  Leakage of fluid great enough to form drops,  but  not  enough  to  cause  drops  to  drip  from  item checked/inspected. c. Class III  Leakage of fluid great enough to form drops that fall from item checked/inspected. d. Paving machine operation must stop and maintenance   performed   if   any   steady   stream   leak   of hydraulic oil is detected. e. Paving machine operation must stop and maintenance performed if any fuel leak is detected. 2.7 PMCS PROCEDURES. a. Preventive  Maintenance  Checks  and  Services, Table 2-1, lists inspections and care required to keep the paving machine in good operating condition.  Table 2-1 is set   up   to   make   BEFORE   OPERATION   checks   while walking around the paving machine. b. The    ITEM    NUMBER    column    of    Table    2-1 provides  numbers  for  each  check  or  service  task.    Use these numbers as a source of item numbers for the TM Number   column   on   DA   Form   2404   when   recording results  of  PMCS.    The  PMCS  routing  diagram,  located directly before Table 2-1, shows the location of all PMCS checks by item number. c. The  INTERVAL  column  tells  when  to  perform  a certain check or service. d. The LOCATION column gives the location of the item checked. e. The   ITEM   TO   CHECK/SERVICE   column   lists the item checked or serviced.  This column is combined with the LOCATION column. f. The    PROCEDURE    column    tells    how    to    do required   checks   and   services.      Carefully   follow   these instructions.    If  tools  are  not  available,  or  if  directed  by procedure, notify the supervisor. NOTE Terms "ready/available" and "mission capable"   refer   to   the   same   status: equipment is on hand and ready to perform   its   combat   missions.      (See DA PAM 738-750.) g. The     NOT     FULLY     MISSION     CAPABLE     IF: column  tells  when  the  paving  machine  is  not  mission capable and why the paving machine cannot be used. h. If   the   paving   machine   does   not   perform   as required,  refer  to  Chapter  3,  Section  II,  Troubleshooting Procedures. i. If   anything   looks   wrong   and   cannot   be   fixed, record it on DA Form 2404 IMMEDIATELY, and report it to the supervisor. j. When performing PMCS, a rag or two is always needed.    Following  are  checks  that  are  common  to  the entire paving machine: (1) Keep it Clean.  Dirt, grease, oil, and debris only get in the way and may cover up a serious problem. Clean   while   working   and   as   needed.      Use   cleaning solvent on all metal surfaces.  Use soap and water when cleaning rubber or plastic material. 2-11
