Authorized reproduction of the users / instruction manual for a Brother model 1241 and according to our customers, model 1231 is very similar to Brother's model 1241 so this manual applies to it too. It is a round bobbin, zig zag sewing machine and many of its basic attachments are covered in the manual. It has basic information, cleaning and oiling information and some troubleshooting information.
