If you purchase a machine without a manual, a lot of time gets spent finding one. Don't pay for any Viking-Husqvarna machine manuals! While they break the bank with the cost of cords and foot controls, this manufacturer at least provides free complete manuals on their website IF you find the correct link.

When I added this link, the http:// showed up. Try it without that portion. That's how it has always worked for me.
Scroll down to your machine, click, and upload the pdf in full page form. My eyes like that!
I truly hope this helps someone. Now, I just need to find the powercord plug for my HV Classica 100 and foot pedal that works with the cord. Good thing the machine is like new or the cost wouldn't make it worthwhile!
