Any tips on handling brand new congas?

I've just taken out of dusty boxes a very nice looking pair of Meinl Marathon Exclusives - Conga and Tumbadora.
I've ended up with them by accident when they were misnamed in an ebay auction. They sound very nice, they were a good price and look stunning. I was also very pleased to see that there were some very positive comments about them on this forum. So I'll be keeping them.
I'm a beginner, these are my first congas and here is my question. Have you any tips for getting the best out of them when they are fresh out of the box?
Thanks.
