Yep, drift key slips through the slot in the arbor to remove the spindle. To remove the chuck from the spindle I leave the spindle in the arbor and use a piece of wood as a pad and tap around the top edge of the chuck gently till she drops off (on my foot). Put a folded up shop towel on the table so it can fall on that (then roll off and drop on your foot). The manual is probably available online if you have the model number and a login to the DeWaltDeltaBlackandDeckerBeisemeyerPorterCable service site. If you can't get on, give me your model number and I'll try to pull a PDF for you.
Any sufficiently advanced technology is indistinguishable from magic.
