CAUTION
●
This machine is equipped with a thread detecting mechanism. If the machine is not threaded
with the upper thread, the machine will not operate correctly, even if the start/stop button is
pressed after unlocking the machine.
●
If the machine suddenly stops:
- Turn off the machine, and unplug the power cord.
- Restart the machine with the correct operating procedure. Refer to page 20.
Probable Cause
Replace the needle. Dull
needles have a difficult time
passing through the garment,
causing fabrics to tear.
The simple penetration of the
needle could damage delicate
fabrics. Use stabilizer on top of
fabric.
Adjust the tension according to
the type of fabric and thread
being used. Polyester thread will
stretch during sewing especially
if the tensions are set too high.
After the stitching is complete,
the thread returns to its original
strength, causing puckers in the
fabric.
Tightly frame non-stretchable,
woven fabrics. Loose framing
will cause the fabric to bunch
up under the stitching.
Tautly frame soft knits using a
stable backing. Overstretching
the garment will cause it to look
puckered when the frame is
removed.
Re-digitize the design with fill
stitching or with multiple rows
of column stitching.
Dull needles push fabric down
and damage material. Replace
the needle.
Too many stitches in an area
pull fabric, causing it to pucker.
Slightly decrease the design
density by 5% to 10%.
Adjust the contrast on the LCD.
