This was my second machine. I bought it after the Brunsviga 13RM. That machine only needed cleaning and oil.
When I bought this Hamann machine, it would add with some force applied, but didn’t subtract. Cleaning didn’t change anything.
It took some time before I saw something strange, something that didn’t look right. Well ... it not only looked wrong, but also appeared to bé very wrong. I needed to remove the main register from the machine and partly disassemble it before I understood the mechanism and what was so wrong. (See the first two photo’s)
After bending the +/- selection mechanism back to it’s original shape and putting it all together, the machine did work properly. At the same time I thoroughly cleaned and oiled it as well. Now its movement is smooth and light at any operation. If you like, see the video of a subtraction.
