Luggage Lock TSA20 Instruction Manual (Manufactured by Lewis N. Clark, L.C. Industries, Chicago, IL)

While traveling, I had opened the TSA20 lock and unknowingly put it into an unknown mode... I could not pull the shackle up out of the lock and it was stuck in the down mode, but not with the open end of the shackle plugged into the shackle socket.  If I turned it the shackle, it turned the numbers and nothing I did with the numbers allowed me to release the shackle.  I thought it might be in the mode to reset the lock combination. But I didn't have the instructions. I was now unable to use the lock and the instructions were home, not with me. I've posted them here for myself and anyone else who might find them useful.

To solve my immediate problem, I found youtube instructions for how to open a lock if the combination was forgotten, but not how to handle setting the lock combination or how to get out of this mode.  I managed to use the youtube instructions for releasing the lock (I inserted manicure scissors into the key hole and turned 90 degrees and that allowed the keyhole portion to be pulled out of the lock and that seemed to release the whole thing.  Indicates just how easy it is to unlock this lock by anyone with a pair of pointy tweezers or manicure scissors, or a key you can buy on Amazon.).  Anyway, here are the instructions that came with the lock.  Not sure how I got it in the funky mode, but I think I pushed the lock shackle in while the combination was set, but I pushed it in without aligning it to the socket for the shackle--it was slightly off.  Nervous this might happen again.
