"Seating" in dremel brushes? Answered

I just got me a dremel yesterday. I was reading the manual and I found it said i need to run the dremel for 5 minutes without a loud on highest speed. Does this mean i have to remove the collet nut and the collet?

No. You can run it even with something in the collet. Just don't let it touch anything.
