Old Lady Adler 467 373 Thread Problem

[LeoWe]

Hello, I’ve received an old lady. She spent 10 years in a basement. It’s an Adler 467-373 that comes from an upholstery shop.

My problem is that it frays the upper thread, and I think the timing is off.

I cannot find the screw on the shaft to loosen the hook on this model.

I’m sure you can help me. I’ve attached a few pics. 
 

thank you

So cleaned her and tried to set the hook timing right. Now she stitches on paper but if I try thin leather after a few stitches the upper thread gets splittet . The needle is new .

Is the needle the right size for the thread?

There's a chart here:

I'd advance the shuttle a bit so the tip arrives a little higher above the needle's eye.

or the needle bar it set a bit to high. I´d check the whole needle hook timing.

Hello Guys, I am really sorry for the delay. I got  very sick and was out of order for a few days. Today ist the first day I am getting better so I’ll read all replies and will also answer them all  

thank you 

best regards

Do you have a user manual?

These three separate adjustments work together to form a stitch without splitting the thread:

1. Needle bar rise (how far the needle has risen from bottom dead center when the hook point crosses the needle)
2. Needle bar height (where in the scarf the hook crosses the needle)
3. Hook to needle distance (How much space between the hook and the scarf...ideally none)

Don't forget the take-up spring adjustment.
