Just for your information for when the organ is fixed:
Oiling is simple and should hurt a thing. When you open the back of the organ, you'll see two metal/tin-like cups that funnel to the necessary organ parts. Fill them up with Hammond Tonewheel Generator Oil to about 1/2 to 3/4 full and that's it. The oil will empty out of the cups quickly so don't try to make them stay full. Over-oiling will only cause more oil to leak out of the bottom of the organ and onto your feet.
Again, only use Hammond Tonewheel Generator Oil (accept no substitutes). Anything else (olive oil, sewing machine oil, motor oil, anointing/holy oil, etc.) will cause BAD things to happen.
If the organ is used regularly, then oil it every 3-6 months, but you can really go up to a year without oiling it and the organ should run fine. Those things were built to LAST. When people say, "They don't make `em like they used to," they're talking about vintage Hammonds!
