CAUTION Always   wipe   clean   oil   filler   components   before   starting   your   lube service.  Use correct type or grade of oil.  Overfilling will cause spillage and harm engine components. b.    The engine oil filter shall be changed as applicable when: (1) It is known to be contaminated or clogged. (2) The prescribed hard time interval has arrived. c.    This  generator  set  is  not  enrolled  in  the  Army  Oil  Analysis  Program  (AOAP).    Hard  time  service intervals apply. d.    For  equipment  under  manufacturer’s  warranty,  hard  time  oil  service  intervals  shall  be  followed.   Intervals  shall  be  shortened  if  lubricants  are  known  to  be  contaminated  or  if  operation  is  under  adverse conditions (such as longer than usual operating hours, extended idling periods, or extreme dust).
