How to thread a Riccar 540 sewing machine, top and bottom?

RICCAR R950 Instruction Book

Riccar sewing machine manuals

Sewing machine Riccar Super Stretch 505

Even if it's not your model machine, the threading instructions and basic use would be similar.

increase the needle thread tension
the term is bird nesting and is caused because the needle thread is not pulling the bobbin thread up

RICCAR 564DE Instruction Manual Page 13

try changing the needle
check to make sure the top thread tension is not to tight
check to make sure the thread is not caught somewhere
change the thread
clean under the needle plate & in the bobbin area for loose threads or lint

HI
Try finding a threading diagram in a manual for another riccar machine here.

I couldn't see a manual here for the Riccar Reliant 57 but there are ones for the RL570 etc.
Most machines by the same brand thread in the same way.
Hope this helps!

Try looking for a manual for your machine here.

If your model number isn't listed try looking for a similar model or the number nearest to your machine.
Usually, sewing machines of the same brand thread in the same way. Hope this helps!

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.
