NOTES: 5.    MAIN ENGINE CRANKCASE OIL LEVEL Before starting engine, open engine oil level access door (5) and check to ensure that oil level is at least to, or above, the low (L) mark on the dipstick.  If not, add oil to bring level to above L mark on dipstick (see key for required oil type).  Check for hydrostatic lock.  Start engine.  Warm up engine to normal operating temperature.  Stop engine and wait 3-5 minutes.  Check oil level again.  If oil is within OPERATING RANGE (between Land full, or F, mark on dipstick), do not add oil.  If oil level is below the L mark, add oil to within upper limits of OPERATING RANGE on dipstick (see key for required oil type).  Main engine oil fill cap (6) is in engine compartment. NOTE •After an overnight stand, oil level may be from 3/4 to 1 inch above F mark   on   dipstick.      This   is   not abnormal.    However,  if  oil  level  is more  than  1  inch  above  F  mark, have  engine  checked  for  internal coolant or fuel oil leaks. •Transmission  and  engine  contain preservative oil upon receipt. Preservative   engine   oils   PE1   and PE2  are  identical  to  engine  oil  OE- 40, except they contain a preservative additive.  PE1 and PE2 will be used in the same manner as the regularly used engine oilOE-40. PE1   orPE2willalsobe   used   in   the transmission until the first scheduled 2000-mile or semiannual oil change. E-7
