Wow, thanks to you i have the first machine up and running already :D

It’s amazing how hard it is to put back together - it’s not obvious what parts go in first - i had to redo it a couple of times because i blocked access to screws by other parts.

I did have some problems with adjustments here and there, but nothing i couldn’t figure out, apart from one thing i cannot figure out:
When printing symbols, the platen drops down, but not nearly enough - it’s not heavy enough on it’s own to go to the bottom position. On the center (back) of the machine i see a spring that keeps the mechanism in balance. I cannot see any adjustments possible here to allow the unit to level correctly - have i overlooked anything?

Apparently, my machine does not have the memory transmitter fitted - the machine on your picture looks a lot different with all that extra mechanics on top.

I will make some video and take some pictures of the cleaned machine when i get some more time.

Regarding the motor, it’s not a synchronous like i first thought - it’s a 4000 RPM Siemens Schukert motor with governor fitted to keep it at 1500 RPM(?) - Is this available as a spare for the other machine, and how costly are they?

Thanks!

The big question is - is there any part of the machine that will be hurt by a soaking into turpentine/oil-mixture? I am thinking of the felt-washers in the clutches. Of course, i won’t submerge electronics, motor, keys etc. into it, but all the mechanics has this brown dried-on crud that i want to remove by soaking it.

To press the Danish special characters (Æ, Ø, Å) i have to press the “figures” keys to unlock them - does this mean that the machine does not have this special mechanism?

I looked over the electronics for dying electrolytics and selenium rectifiers, but found none, so i’ve had it powered on, and the electronics work, but the mechanics have issues. Primarily with dried-on gunk and oil (oil went brown on shafts)

It’s a 1500 RPM syncronous motor on this model. I will have to see if i can fabricobble something together with another motor and then maybe 3D-print some crown-gears, as making a new worm-gear is out of my reach.
