Using The Twin Needle - Brother Innov-is 2500D Operation Manual

LOWER/UPPER THREADING

Using the Twin Needle

Using the twin needle, you can sew two parallel lines of
the same stitch. Although the same bobbin thread is
used, interesting patterns can be sewn by threading
each needle with a different color of thread. Both upper
threads should have the same thickness and quality.
The twin needle can only be used with patterns where
appears when they are selected. Check the
"STITCH SETTING CHART" at the end of this manual
for patterns that can be used with the twin needle.
• Use only twin needles made for this machine (part
code X59296-151). Other needles could break,
resulting in damage.
• Be sure to set the twin needle mode when using the
twin needle. Using the twin needle while the
machine is in single needle mode could cause the
needle to break, resulting in damage.
• Do not sew with bent needles. The needle could
break and cause injury.
• When using the twin needle, be sure to use presser
foot "J". In case bunched stitches may occur, use the
presser foot "N".
