I don't think I would want to have the machine just sitting on the casters 
on a wood floor. You are putting a lot of pressure on just about one or two 
square inches of each leg. If you are going to use them, I would get some 
plywood or other material about a foot square and atleast 1/2 of an inch 
thick to set them on after rooling the machine in place.
