How Do You Put Oil in a Welch Duo Seal?

[Springfield Acer]

I am about to fire up an old used Welch Duo Seal 1402 that has no oil in it.
Do I add the oil into the exhaust port?
Do I put any into the intake?
I have a very detailed owners manual that tells you everything except where to put the oil in.
