I just got my 1st one of these, with 6 original bits but without the side handle and at a great price. I just need to know how the chuck is loosened from a tight closed position. I got the chuck off the threaded shaft but I cannot see how the jaws open and close, it looks like the chuck has two holes on the bottom on either side of the thread hole so is that the lower bottom peice turns, apart from the upper connicle part that has the jaws? Like maybe I need a spanner U-wrench to loosen it?
Thanks anyone who can help,
Alex
