I was kind of intimidated, first I have owned, set up %26 threaded; however, Singer site had manual online. Downloaded %26 printed manual (highly recommend you do the same),°, acquainted myself with the basics, followed step-by-step instructions %26 threaded it correctly first time trying. Not all that complicated. color coded path helps.
Watched a YouTube video, Australian man was the best, he made it look easy.
Serger worked beautifully. completed 2 projects in 5 minutes!
Awesome investment for the new, intermediate sewists.
Love the Singer Heavy Duty line. Highly Recommend.
