Dust, thread clippings and fuzz may build up in your machine over time slowing it down and possibly causing damage. We want you to be able to use our machines to their best abilities! Follow these simple video instructions on how to remove and clean the bobbin area of your Quick-Set™ top drop-in bobbin, as well as how to reassemble it! We recommend doing this after each project, or more often if you are sewing extremely fuzzy fabrics. Sew on!
