it's in the manual and it's just a good idea.
True enough.
Mine just never moves. My grandfather never bolted it down, and that was just normal to me.
I can put it wherever I want. Get it out of the way if I need to, set it on a table.
While I agree that for overall safety, bolting it down is the best course of action, I have never needed to do so. A good grinder doesn't bounce all over the place.
Someone else mentioned about sparks, and molten metal. In general that isn't a problem, although depending on the metal being ground, and the material the sparks are landing on, and how far away it is, it could easily become a fire hazzard.
If nothing else, you are going to end up with sme nice scortch marks on the table, and holes all over your sofa. Foam is much more flamable than wood.
A bent piece of tin as a spark guard is all thats required to prevent this problem.
In any circumstance though, keep a ready supply of water or a fire extinguisher just for safety's sake.
