OK, I took a look at a schematic. It looks like it has a drain valve that goes into the engine, then the oil comes out and goes thru a small hose 90 degrees to the valve. Looks like it has a plastic knob that turns to release the oil. If you look and see a small hose with a crook in it, that's it. Take a look here. Number 24 is what you are looking for.
I don't know your particular setup but I've heard of some guys going to the hardware and buying a handful of pipe elbows, unions, stubs and a plug then cobbling together an extension to get outside the frame.
Sometimes you have to wonder if the design engineers have ever repaired or done any of their own maintenance.
