To adjust feed dog height, loosen these two screws (red arrows) and rotate the clamp on the shaft. It’ll be a very small adjustment.

 

Thanks for all the other photos, by the way! They will be useful before too long.

Thank you Uwe!

You do not need any manuals when you got Uwe!

I am new on working on sewing machines so I first have to find information how to lower  the  feed dog.

I see we have the same interest on vintage Volvos!

Yes Volvo made good cars, I still drives a Volvo. I have vintage one too, but I'm not very active with that hobby for the moment. Sewing machines and cars have much in common, you got to learn how to use and maintain them. Just pressing the pedal will only get you so far. If your interested in what your doing, you will obtain the knowledge you need to manage them.

nice topic , at least now i know why my machine doesn't have bottom feed , and it seems it doesn't like thick thread eather . i can get it to run "20" thickness (think that's 135 in other format) but can't get it to run "10" (or 270) , it will shread the upper thread to pieces. (still used a "20"/135 bottom wire).

does anybody know if you can adjust the stitch length , as far as i'm aware it should be 4.5mm max , but mine wil only do 4 mm (and that is with the stitch controller arm screwed all the way down without the plastic block in place (still waiting for that to arrive)

Yes these machines aren't made for anything larger than max 20 thread, maybe 15 on top and 20 in the bobbin. I guess you even have trouble getting anything thicker than 20 in to the needle bar thread guide. Using anything thicker is just the same as asking for trouble. I don't think your machine even have a hook safety clutch, birds nests could get real serious.
