ii PREPARATION FOR THREADING Your machine comes threaded. If you wish to change thread, an easy method for threading is tying on threads. (refer to page 5) If machine runs out of thread, it is necessary to rethread machine. (refer to Page 6) Connect AC adaptor (only) to turn on light for threading. For best sewing performance use proper spool cap. Large size cross wound Not required Unplug foot switch. Swing thread guide holder up to operating position. Remove front cover by lifting gently at tab on right side. Slide spool cap firmly against rim of spool to prevent thread tangling.
