Spring foot free-motion (4.2)
Activate to set the machine in spring foot free-
motion mode. Lower the feed dogs. A spring foot
will raise and lower with each stitch to hold the
fabric on the stitch plate while the stitch is being
formed.
In sewing mode, press the info button. The
spring foot free-motion icon will be shown
instead of the presser foot recommendation.
A pop-up will inform you that spring foot free-
motion is active when turning on the machine.
Note: The open toe free-motion foot is optional and can
be purchased at your local authorized PFAFF ® dealer.
Do not use if sensormatic free-motion is activated, since
the needle might damage the presser foot.
The open toe free-motion foot, or any spring foot with
light grey plastic housing, can also be used for free-
motion embroidery.
Sensormatic free-motion (4.2)
Activate to set the machine in sensormatic free-
motion mode for presser foot 6A. Lower the feed
dogs.
In sewing mode, press the info button. The
sensormatic free-motion icon will be shown
instead of the presser foot recommendation.
The fabric must be moved manually. When sewing
in free-motion at low speed the presser foot will
raise and lower with each stitch to hold the fabric
on the stitch plate while the stitch is being formed.

fabric while sewing.
When turning on the machine, a pop-up informs
you that the sensormatic free-motion is active.
Pivot height (4.2)
Adjust the height of the presser foot when the
machine is set for free-motion.
In Sensormatic free-motion mode, the fabric
should move freely under the presser foot.
Skipped stitches can occur if your fabric moves
up and down with the needle as you are stitching.
Lowering the pivot height will reduce the space
between the presser foot and the fabric and
eliminate the skipped stitches.
Note: Be careful not to reduce the pivot height too much.
The fabric must still move freely under the presser foot.
Presser foot pressure (4.2)
In most cases, you do not need to adjust the presser
foot pressure. To improve the result when using
specialty techniques, adjust the pressure.
Use the left and right arrow buttons on the wheel
to adjust the pressure. The higher the number,
the more pressure on the fabric. The value can
be adjusted between 0 and 9 in steps of 0.5. Your
manual setting will be cancelled when you turn the
machine off.
Note: If you want to change the presser foot pressure for
an entire sequence, bring the sequence to sewing mode
and change the setting there.
Automatic presser foot lift (4.2)
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.
Balance
When sewing on special fabrics or doing a special
technique, the balance may need to be adjusted.
Start by sewing a stitch on a piece of scrap fabric.
Use the left and right arrow buttons to balance the
stitch between -7 and 7. When you sew again, the
balance will be adjusted.
The changes only affect the selected stitch. The
setting will go back to default when you select
another stitch.
Language
Use the left and right arrow buttons to change the
language of all text in your machine.
Audible alarm
Turn all alarm sounds of the machine on or off.
Default setting is on.
Contrast
Adjust the contrast of the graphic display by using
the left and right arrow buttons. The value can be
set between -20 to 20 in steps of 1.
Software version
Check the software version for your sewing
machine.
