Where Can I Download A User Manual For A Husqvarna Huskystar E20 Sewing Machine?
I emailed the company customer service address and they emailed a manual back.
I found a E-20 manual online (36 pages). I can refer you to the site which requires a brief sign-up and may expose you to resulting e-mail or I can send you an Adobe copy if you'd like as an e-mail attachment.
