REMOVAL WARNING Hydraulic oil in the system can be under pressure over 5, 000   psi   with   the   engine   and   pump   OFF.      ALWAYS relieve  pressure  in  hydraulic  lines  before  attempting  to remove  any  component  in  the  hydraulic  system.    With the    engine    OFF    and    hydraulic    attachments    on    the ground,    move    control    levers    through    all    operating positions several times to relieve line pressure.  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. 16-98
