I have been given a Stitchmaster 1978 sewing machine but can’t see to get the top threading correct. I do not have a manual and can’t find one online! Any advice gratefully received.

You can try looking at some web sites & videos for threading sewing machines. Most machines thread similarly so you may find something close to your machine. Remember to ALWAYS RAISE the presser foot when threading the top thread.

Euro-pro sew & go b410 sewing machine: Diagram on how to thread it?

Am unable to locate a picture of your machine, but the attached link is threading instructions for a 416. Perhaps it is close enough to your machine model to be beneficial:

Oh yes, one more HINT: ALWAYS RAISE the presser foot when threading the top thread!

Otherwise, search for:

Make Model threading

and see if anything comes up that is helpful.

Or try this manual:

Remember that sewing machines basically operate the same. Even though the design has changed over the years, the threading process and sequence remains the same.

I need the correct setting for my singer merritt 3140...I keep getting bundling thread from the bobbin

Always remember that it is the opposite of what you think, it is not the bobbin thread - it is your upper threading, you don't have it threaded right. Go to and download the manual for free and then enlarge the threading page. I am sure that you will be amazed, because I sure was. Good luck

Hi i just got a new brother 1034D serger. And I'm

I found that I had to remove the stitch finger to thread the machine properly. Do remember to re-install it before starting to sew. If you are using 3-threads only, then remove and store the stitch finger.
Puzzled that this instruction is not in the threading section of the manual.
