■ Upper tension is too loose
Loops appear on the wrong side of the fabric.
Note
● If the upper thread was incorrectly threaded, the upper
thread may be too loose. In this case, refer to “Upper
threading” (page 15) and rethread the upper thread.
Solution
Increase the tension by turning the upper
tension-control dial to a higher number.
Various ways to achieve better results for your sewing projects are
described below. Refer to these tips when sewing your project.
A trial piece of fabric should be sewn. Use a piece of fabric
and thread that are the same as those used for your project,
and check the thread tension and stitch length and width.
a
When the stitching reaches a corner, stop the sewing machine.
Leave the needle lowered (in the fabric). If the needle
was raised, lower the needle either by turning the
handwheel toward you (counterclockwise) or by
pressing (needle position button) once (for
models equipped with the needle position button).
b
Raise the presser foot lever, and then turn the fabric.
Turn the fabric using the needle as a pivot.
c
Lower the presser foot lever and continue sewing.
Stop sewing, and then slightly change the sewing
direction to sew around the curve.
When sewing along a curve while using a zigzag stitch,
select a shorter stitch length in order to obtain a finer stitch.
■ If the fabric does not fit under the presser foot
If the fabric does not fit easily under the presser foot, raise the presser
foot lever even higher to bring the presser foot to its highest position.
■ If thick seams are being sewn and the fabric does
not feed at the beginning of stitching
The fabric may not feed when thick seams are being
sewn and the presser foot is not level, as shown
below. In this case, use the presser foot locking pin.
a
Raise the presser foot lever.
b
Align the beginning of stitching, and then position the fabric.
c
While holding zigzag foot “J” level, hold the
presser foot locking pin (black button on the left
side) pressed in, and lower the presser foot lever.

while the needle is lowered, the needle may bend or break.
