Ingersol Rand

How do I change the engine oil on my Ingersol Rand 741 compressor?
No holes underneath to get at a drain plug. There are 3 allen headed studs under the left hand front corner,are these drain plugs? or is it one of those engines that needs the oil sucked out of the dipstick hole.

There is no sump plug showing as in the pics on page 120.
bottom belly plate totaly flat and no holes or plates. all there is is one drain plug underneath the left front corner and above it is three allen headed studsas in pics.

Take the left hand plug out and see what runs out....
