Blickensderfer 6 Cleaning and Maintenance

From Typewriter Wiki

Replace Type Head on Main Body Assembly

First, get a pipe cleaner or something similarly long and slender.
Push all three of the toothed arms on the main body forward and hold them in place. This is where the pipe cleaner comes in. Put it under two of them, and all three should stay where they are.
Place the type head carefully down, and when it catches, press space just a tiny bit.
Watch for the front toward the keys. There's a small pieces that sticks out that has to stick out on top of the comb (the bit that holds the key levers apart). If it doesn't, then you can't press the keys all the way because it locks up the keyboard. Loosen the type head just a tad and pull it in place if it's not where it should be.
