Machine is definitely a keeper.

Well - I´m not 100% sure but the tension unit looks like one from a Pfaff 138. That does not mean your tension unit does not work with the machine but I think its not the original tension unit. Adler tension units look different they look like this:

and yours has 2 tensions (thats for double needle machines, sewing tucks and so on) and seems you run the thread through both of them - thats basically wrong.

Try to thread your machine a different way - go from the thread guide on top of your machine directly to your tension unit and thread it as shown in this picture and try again sewing.

 

 

Yes I agree my 69 machine has the same looking unit as Constabulary has shown in the top picture. I wonder if some mechanic has installed this unit with the intention of increasing the top tension further without tightening the spring all the way in, as happens at times when using a large bobbin thread through thick material??? At any rate I would take off the tension discs of both and check if they have any roughness or grooves. Periodically I take mine off and polish them with a rag wheel and tripoli polish on a bench grinder. This may help with the top thread fraying problem mentioned. Another problem on some threads is when going very fast, stopping and going fast again. When I stitch full belt lengths at times the heat generated on the needle starts to melt the thread and I have found it best to slow down the machine the last 3 or 4 inches before stopping. Sorry I can't help with the steel bobbins as I am in Australia. Regards Brian

Also,

In the video on the 69 showing how to wind bobbin, thread machine and sew, the machine is NOT thread correctly in the take up spring area. It is threaded behind the location pin on the the take spring assembly and that is WRONG.  I have owned and sewn on these machines and you do no thread behind that pin!

Thanks for that Shoepatcher.

Yes! I always figured something was up with the tension discs because they never looked like the ones in pictures of other Adler machines. I am moving this weekend and haven't/won't have time to do anything right now but can't wait to check on these issues that you have mentioned here and report back. It would be very nice to have this machine in good working order.
