NOTE No damage will occur to the motor and pump  assembly  (7,  figure  1-12)  when the  residual  oil  has  been  completely pumped   from   the   system   lines   and reservoir. I.    Energize  the  OIL  PUMP  START  switch  (15, figure  1-26)  and  allow  the  residual  oil  to  discharge  into the  waste  oil  container.    When  the  ENGINE  LOW  OIL LEVEL indicator (17, figure 1-25) comes on, depress the OIL PUMP STOP switch (23, figure 1-26). m.      Add   Specification   MIL-L-23699   oil   to   the system oil reservoir until the ENGINE LOW OIL LEVEL indicator  (17,  figure  1-25)  on  services  panel  assembly 4A1 goes off. n.  Place the manual selector valve (10, figure 1- 12) in the T74 position. o.    Energize  the  OIL  PUMP  START  switch  (15, figure  1-26)  and  allow  the  residual  oil  to  discharge  into the  waste  oil  container.    When  the  ENGINE  LOW  OIL LEVEL indicator (17, figure 1-25) comes on, depress the OIL PUMP STOP switch (23, figure 1-26). p.      Add   Specification   MIL-L-23699   oil   to   the system oil reservoir until the ENGINE LOW OIL LEVEL indicator  (17,  figure  1-25)  on  services  panel  assembly 4A1 goes off. q.  Place the manual selector valve (10, figure 1- 12) in the T63 position. r.    Energize  the  OIL  PUMP  START  switch  (15, figure  1-26)  and  allow  the  residual  oil  to  discharge  into the  waste  oil  container.    When  the  ENGINE  LOW  OIL LEVEL indicator (17, figure 1-25) comes on, depress the OIL PUMP STOP switch (23, figure 1-26). s.    Remove  the  drain  plug  (8,  figure  1-12)  and allow the waste oil to drain into the container.  Install the drain plug when the oil reservoir has completely drained. t.  Remove the hose assembly from the oil supply and oil return quick-disconnects (4). u.  Connect the oil supply line (16) and oil return line  (18)  disconnected  in  step  (k).    v.    Deenergize  the following  switchlight  units  on  services  panel  assembly 4A1 (9, figure 1-25): ENGINE DC (27) 115 VAC 400 HZ (28) INST DC (29) CONSOLE DC (30) 26 VAC 400 HZ (31) w.  Depress the INS' PWR OFF switch (31, figure 1-26). x.  Deenergize the diesel engine ac generator set as specified in chapter 2, Preliminary Checkout Prior to Test paragraph. y.  Service the test trailer oil system as outlined in paragraph   6-8,   using   Specification   MIL-L23699   oil   in place of the oil specified therein. z.  Check the operation of the oil quantity system as outlined in paragraph 5-17. aa.    Make  an  entry  in  the  system  log  to  indicate compliance with the foregoing instructions. 6-10.  Portable Oil Unit.
