That's a question for DeWalt's service people to answer. Check the Contact link on their website.
That said, if it's for a table, you might consider some serious dust collection in the fence. Maybe replace the plastic shield with some kind of suction thingie. You could even make a couple of channels under the table to pull the dust out and away from the router. I accidentally drilled a half inch hole in the wrong place on my plate, and discovered that it sucked up sawdust.
The more I do, the less I accomplish.
