FAQs & Troubleshooting

How do I sew with the twin needle?

Only use the twin needle (2.0/11 needle, part code: X59296-121). Use of any other needle may bend the needle or damage the machine.
Never use bent needles. Bent needles can easily break, possibly resulting in injuries.
The needle threader cannot be used with the twin needle. If the needle threader is used with the twin needle, the machine may be damaged.

Be sure to use the twin needle, the horizontal spool pin and the appropriate spool caps.
With the twin needle, you can sew two parallel lines of the same stitch with two different threads.
Both upper threads should have the same thickness and quality.
For details on the stitches that can be sewn with the twin needle, refer to “Stitch Setting Chart” in the operation manual.
Traditionally a twin needle is also used for creating pin tucks. Contact your nearest authorized Brother dealer to obtain the optional pin tuck foot for your machine (SA194, F069: XF5832-001).
