You should thread each needle separately.

pass the thread through the guide above the
needle before you pass it through the eye of the
right needle.

● Do not turn on the machine while
pressing down the foot controller. The
machine may start unexpectedly and
cause personal injury or damage to the
machine.
● After selecting a stitch, slowly turn the
handwheel toward you
(counterclockwise) and check that the
needle does not touch the presser foot. If
the needle hits the presser foot, the
needle may bend or break.
● The twin needle should only be used
with the Straight Stitch (Center Needle
Position) and the Zigzag Stitch (1.5 mm
(1/16 inch) width). Do not use the twin
needle with any other stitches.
● When changing the sewing direction, be
sure to raise the needle from the fabric,
and then raise the presser foot lever and
turn the fabric. Otherwise the needle
may break or the machine may be
damaged.
