I use the following method(s) to clear the lead jam. First I remove all of the spare leads from the reservoir up under the eraser, since those spare leads automatically feed into the barrel and might further jam the lead advance mechanism, if left in place. Then I hold down the “click click” mechanism of the pencil so the writing tip opens up and releases its pressure on any lead still inside the barrel of the pencil, and withdraw the piece of lead that sticks out the end of the pencil (if necessary, with a household tweezers). If that doesn’t seem to restore proper function, then I hold the pencil cap down on my desk (on top of a pad of paper, to keep the resulting lead shavings mess off my desk), and press the pencil downward against the desk so the writing tip opens up and releases its pressure on any remaining lead. While the writing tip is thus held “open”, I start “drilling” down through the writing tip with the lead drill. Often you don’t have to “drill” very far, since the jam is usually confined to the area behind the very end of the writing tip. In this particular case I only had to turn the drill two or three revolutions. Gently pushing down on the drill rod then dislodged the rest of the lead jam, which exited the pencil through the (empty) lead reservoir at the other end of the pencil. Then I checked for proper functioning with a fresh 1-7/8" piece of lead, loaded into the pencil the “wrong way” (from the writing tip end, with the mechanism held “open”), and the “click click” mechanism now worked just fine.
