Item Interval Item to be Inspected Procedure:  Check for and have repaired, filled, or adjusted Equipment is not Ready/available No. B   D   A  W  M as needed if: TM 5-6115-365-15 e. Hydraulic   Lines   and   Fittings.      Look   for   wear, damage,  leaks,  and  make  sure  clamps  and  fittings  are tight.      Wet   spots   show   leaks,   of   course,   but   a   stain around a fitting or connector can mean a leak.  If a leak comes   from   a   loose   fitting   or   connector,   report   it   to Organizational  Maintenance.    If  something  is  broken  or worn out, report it to Organizational Maintenance. 21-2.3.  Fluid Leakage It is necessary for you to know how fluid leakage affects the  status  of  the  fuel,  lubricating,  coolant,  and  hydraulic systems. The following are definitions of the types/classes of leakage you need to know to be able to determine the status of your equipment.  Learn, then be familiar with them and REMEMBER --WHEN IN DOUBT, NOTIFY YOUR SUPERVISOR! CAUTION Equipment    operation    is    allowable with   minor   leakages   (Class   I   or   II) except fuel. Of    course,    consideration    must    be given   to   the   fluid   capacity   in   the item/system being checked/inspected.    When  in  doubt, notify your supervisor. When   operating   with   Class   I   or   II leaks,  check  fluid  levels  more  often than required in your PMCS. Class  III  leaks  should  be  reported  to your  supervisor  or  to  Organizational Maintenance. 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 being checked/inspected. c. Class III.   Leakage  of  fluid  great  enough  to  form drops that fall from the item being checked/inspected.
