There are 2 grub screws (one locking the other) in a threaded hole in the side of the head casting. There is also a keyway in the spindle outer sleeve that the grub screws project into and limit the travel. If you remove the coiled spring (chrome thing on side) and the grub screws, the spindle will drop all the way down. The coil spring is tightly wound and gets tighter the further down the spindle is so remove it with the spindle near the top of its travel. You'll also need to withdraw the quill handle through the right side of the head.
Hope that helps. |
