• Always double check threading before attempting to adjust thread tension.
• Make a test sample to find proper tension before sewing on your fabric.
• Adjust thread tension by slightly turning tension dial.
• Thread tension of your machine has been preset to 5 to suit most
sewing applications. But some threads and fabrics require readjusting
thread tension to improve stitch appearance and eliminate skipping.

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)
• Unplug foot switch.
• Swing thread guide holder up to operating position.
• Remove front cover by lifting gently at tab on right side.
• Connect AC adaptor (only) to turn on light for threading.
• For best sewing performance use proper spool cap.
