Anyone have experience using these things?

My dining room is about 10'-12' wide and it seems that after 80+ years of previous families having dinner on their nice big heavy tables, the dining room floor has developed a pretty good sag. So much so that when I walk across the dining room, there is a nice little bounce to my step! There are other places in the basement where previous owners have installed these jacks, and you can tell because the areas/rooms that they have been installed under are very solid.

Do I need to take any special precautions or purchase any special machines or tools (other than the jacks themselves) to accomplish this? Any suggestions on how to do it?

Thanks!
