SOURCE: Hello I have an old Riccar 6800 sewing machine

Hiya, the threading for this machine is pretty standard so you won't be going wrong there. Have you used a sewing machine before? The tension dial (on the extreme left) should be set at 5. The other dial to your left should be on blue zigzag with orange broken line. The dial on the right should be set at 0 and the bottom one on 2 - 3. I've been looking for a manual for this machine as I inherited this one. It took me ages to suss straight sewing out. Another thought is take it to a repairer and ask for a quote. Good luck.

If not look on www.riccar.com/help/manuals for a similar model.
Find out what shank your machine is and you should be able to buy parts for it. I find ebay great for old sewing machine parts.
Hope this helps!
