SEWING BASICS
h
Take your foot off the foot controller, or press
(start/stop button) once (if the machine was
started by pressing
(start/stop button)) (for
models equipped with the start/stop button).
The machine stops sewing.
i
Raise the needle by turning the handwheel
toward you (counterclockwise) so that the mark
on the wheel points up. (With models equipped
with
(needle position button), raise the
needle by pressing
once or twice.)
This procedure is not necessary if the needle stop
position has been set to the raised position
(page 9).
j
Raise the presser foot lever.
k
Pull the fabric to the left side of the machine,
and then cut the threads by using the thread
cutter.
Memo
When the foot controller is plugged in, start/stop
button cannot be used to start sewing (for models
equipped with the start/stop button).
When sewing is stopped, the needle remains
lowered (in the fabric). The machine can be set so
that the needle will stay up when sewing is stopped.
For details on setting the machine so that the
needles stay up when sewing is stopped, refer to
“Changing the needle stop position” (page 9).
Sewing reinforcement stitches
When sewing stitches other than straight or zigzag
stitches that are secured with reverse stitching,
pressing
(reverse/reinforcement stitch button)
sews reinforcement stitches, 3 to 5 stitches on top of
each other.
Memo
Whether reverse stitches or reinforcement stitches
are sewn depends on the stitch that is selected. For
details, refer to “STITCH SETTINGS” (page 50).
The thread tension will affect the quality of your stitches. You
may need to adjust it when you change fabric or thread.
Memo
We recommend that you do a test sample on scrap
of a fabric before you start to sew.
Correct tension
Correct tension is important as too much or too little tension
will weaken your seams or cause puckers on your fabric.
Upper tension is too tight
Loops will appear on the surface of the fabric.
Note
If the bobbin thread was incorrectly threaded, the upper
thread may be too tight. In this case, refer to “Lower
threading” (page 13) and rethread the bobbin thread.
Solution
Reduce the tension by turning the upper
tension-control dial to a lower number.
Memo
When you finish sewing, remove the bobbin cover and then
make sure that the thread is shown as below. If the thread is
not shown as below, the thread is not inserted through the
tension-adjusting spring of the bobbin case correctly. Reinsert
the thread correctly. For details, refer to page 13, 14.
