I can't find anything for the NatGeo Rock tumber ( I assume it is National Geographic) but I did find a site that has free instructions on how to use a tumber and hints for the best results, The site is Geology.com and they have I hope the information you need. I wish I had better results.

Nothing high tech here. Try it without the o-ring. If the water does not start to leak out in the first 3 to 5 minutes of tumbling you will be ok. Stop it every day to check the water level.
Set the whole thing on a cookie sheet in case it does leak when you are not watching - you don't want a bunch of rock dust and polishing grit on your table or floor in the morning.
You will not damage anything by trying it without the o-ring.
