Relieve  pressure  in  hydraulic  oil  tank  by  loosening  filler  cap very slowly.  Failure to follow these precautions could result in serious personal injury. CAUTION Wipe the area clean around all hydraulic connections    to    be    opened    during    removal    and disassembly.      Cap   oil   lines   and   plug   holes   after removing    lines.        Contamination    of    the    hydraulic system could result in premature failure. NOTE If  more  than  one  hydraulic  line  is  removed,  identify lines   to   assure   proper   installation.      Use   suitable container  to  catch  any  hydraulic  oil  that  may  drain from system. 16-73
