Twin needle
Touch the twin needle icon to open a list for twin
needle width selections. When a twin needle size is
selected, the width of all stitches is limited for that
needle size to prevent needle breakage. The setting is
kept until you deselect the twin needle width.
The stitch width of the selected stitch will
you select a stitch that is too wide for the twin needle
size, a waring pop-up will appear. Select "off" in the
twin needle list to deselect twin needle and go back to
normal sewing.
Select this function when using a straight stitch
presser foot to lock the needle in center position for all
stitches. Stitch width safety will prevent damage to the
needle and/or presser foot.
When turning on the machine with this setting
activated and for every stitch selection that is not a
straight stitch, a pop-up informs you that it is set to
straight stitch. Deselect stitch width safety to go back
to normal sewing.
Note: Twin needle and stitch width safety cannot be used at
the same time.
Presser foot pressure
In some cases, you might need to adjust the presser
foot pressure. Specialty techniques or thick fabric may
require an adjustment. The higher the number the
more pressure on the fabric.
When selected, the automatic presser foot lift is
activated. The presser foot will raise to pivot height for
example when stopping with the needle in the down
position. When deselected, the presser foot will stay
lowered even if the machine stops with the needle in
down position.
When selected, the automatic thread snips is activated.
The threads are cut automatically and the presser foot
raises when sewing is complete, e.g. a buttonhole.
When deselected, no automatic thread snip will be
performed.
