DIAGNOSTIC MAINTENANCE PROCEDURES. 2.10.1.   How  to    Perform    Diaqnostic    Maintenance Procedures.  Paving machine diagnostic procedures are presented  in  a  logic  flowchart.    A  separate  flowchart  is provided for each major system of the machine.  In some procedures separate flowcharts are used to troubleshoot specific paving machine functions. Each diagnostic flowchart uses a series of logical steps. The   steps   are   numbered   in   sequence,   starting   with number  "1".    Each  numbered  step  presents  you  with  a diagnostic procedure and a question about the outcome of the procedure.  For each step an INFO KNOWN block states  what  is  known  about  the  problem  at  the  time.    A POSSIBLE  PROBLEMS  block  indicates  what  problems could   be   causing   the   malfunction.      TEST   OPTIONS presents    methods    or    test    equipment    available    for performing the procedure.  A REASON FOR QUESTION block  states  the  logic  behind  the  procedure.    The  basic information  required  for  troubleshooting  is  presented  in upper case text. When performing a diagnostic procedure, start with step number "1".  Perform each step in sequence and answer the  related  questions.    Each  question  can  be  answered with   "YES"   or   "NO".      Based   on   the   "YES"   or   "NO" answer, continue through the flowchart until you remedy the problem or until the problem is referred to the Direct Support (DS) level of maintenance. The     numbered     diagnostic     procedures     and     related information blocks are always presented on the left hand page.          On     the     facing     right     hand     page,     support information   for   use   by   less   experienced   personnel   is presented  in  lower  case  text.    Procedural  WARNINGS and   CAUTIONS   to   be   observed   are   given   here.      All personnel     shall     observe     the     warning     and     caution statements. Paving machine electrical and hydraulic system diagrams  are  included  for  reference  at  the  end  of  the maintenance manual. 2-33
