Even though the following is not your particular model, the process is very similar from one machine to another, so what you aren't able to get from the above links, you may get from these. Be sure to ALWAYS RAISE the presser foot when threading the top thread so the thread will seat properly.

The method will depend on your make & model machine, although the vintage sewing machine buttonhole method will work on all zig-zag machines (just requires manually measuring and adjusting the stitch length & width during the process):

Be sure there is a stabilizer between the fabric where the buttonhole is located so the fabric will not stretch or tear.

I found a manual for several Singer Buttonholers here: http://ismacs.net/singer_sewing_machine_company/manuals/singer-sewing-machine-manuals.html . I'm not sure of the part number for the Professional Buttonholer Model, which looks like the one for my Singer Touch & Sew. Mine is part #161829 (if I read the box correctly).

I hope these help.

Check your manual and follow the instructions. The error message may be listed in the trouble shooting at the back of the manual.

Probably will need to put on the buttonholing foot, pull down a lever which guides the machine to sew the length correctly and choose a buttonholing setting on the stitch selection.

Also, for good buttonholes, always interface the fabric to give it stability.

Automatic BUTTONHOLE making with 979:

1. Carefully mark the position of buttonhole on your garment.
2. Slide the button carrier and insert the button.
3. Attach the buttonhole foot.
4. Place the garment under the foot so that the needle pierces the fabric at the beginning of buttonhole.
5. Lower the buttonhole lever and the presser foot lever.
6. Push the buttonhole lever away from you.
7. Start machine to complete entire buttonhole.

NOTE:

• While making buttonholes, maintain an even sewing speed for uniform buttonholes.
• When buttonholes are completed, be sure to push up the buttonhole lever as gar as it can go.

From what I could find, this machine has a one-step buttonhole feature.

Just today  i got out my little janome i bought years ago and it is this model.  There was no "manual" with the machine.  All that came with it is a large 20X14 two sided print out.  I can scan and send this to you with an email address.  

Winter 2002 was when it was first released. Retail of $499.00.
