Introduction
Presser feet
Standard presser foot 0A with IDT (attached on the machine upon delivery)
This foot is used mainly for straight stitching and zigzag stitching with a stitch length
longer than 1.0 mm.
Fancy stitch foot 1A with IDT
This foot is used for decorative stitches. The groove on the underside of the foot is
designed to Áow smoothly over the stitches.
Fancy stitch foot 2A
When sewing decorative stitches or short zigzag stitches and other utility stitches with
less than 1.0mm stitch length, use this foot. The groove on the underside of the foot is
designed to Áow smoothly over the stitches.
Blindhem foot 3 with IDT
This foot is used for blindhem stitches. The toe on the foot guides the fabric. The red
guide on the foot is designed to ride along the fold of the hem edge.
Zipper foot 4 with IDT
This foot can be snapped on either the right or the left of the needle, making it easy to
sew close to both sides of the zipper teeth. Move the needle position to the right or left to
sew closer to zipper teeth.
Sensormatic buttonhole foot 5A
When connected to the machine, the buttonhole is sewn in a suitable length to the button
size that has been entered into the machine.
Manual buttonhole foot 5M
This foot is used for sewing manual buttonholes. Use the markings on the foot to position
the garment edge. The Ànger on the back of the foot holds cording for corded buttonhole.
Sensormatic free-motion foot 6A (4.0)
This foot is used for sensormatic free-motion sewing. This foot can also be used for
darning.
Rolled hem foot 7 with IDT, 3 mm
This foot is used to sew narrow hems in light to medium weight fabric.
1/4” quilting foot with IDT (4.0)
This foot is perfect for piecing and patchwork, especially when used in conjunction with
the straight stitch needle plate. The clearance between the needle and the outer edge of
the toe is 1/4” (6 mm) and between the needle and the inner edge of the toe 1/8” (3 mm).
Free-motion/Darning foot (3.0 and 2.0)
Insert the pin of the foot as far as it will go into the hole at the back of the presser foot
holder. The ”C-shaped” guide should be positioned around the presser foot bar. The long
arm must be behind the needle bar. Tighten the screw.
Important: Make sure that the IDT is disengaged when using presser foot 2A, 5A, 5M, 6A and
the free-motion/darning foot.

Preparations
Preparations
Unpacking
1. Place the box on a steady, Áat surface. Lift
the machine out of the box, remove the outer
packaging and lift off the machine carrying
case.
2. Remove all outer packing material and the
plastic bag.
3. Slide off the accessory tray and remove the
styrofoam inside.
Note: Styrofoam left in the accessory tray while sewing
may affect stitch quality. The styrofoam is for packing
purposes only and should be removed.
Connect to the power supply
Among the accessories you will Ànd the power
cord and the foot control.
Note: Before plugging in the foot control, check to
ensure that it is type ”FR5” (see underside of foot
control).
1. Take out the foot control cord. Turn the foot
control over. Connect the cord to the socket
inside the space of the foot control. Push Àrmly
to make sure it is properly connected. Lay the
cord in the slot on the underside of the foot
control.
Note: Connecting the foot control cord to the foot
control is only necessary the very Àrst time you are
going to use the machine.
2. Connect the foot control cord to the front
socket on the bottom right side of the machine
(A).
3. Connect the power cord to the rear socket on
the bottom right side of the machine (B). Plug
the cord into the wall socket.
4. Press the ON/OFF switch to ON to turn on
power and light (C).
For the USA and Canada
This sewing machine has a polarized plug (one
blade wider than the other). To reduce the risk
of electric shock, this plug is intended to Àt in a
polarized outlet only one way. If the plug does not
Àt fully in the outlet, reverse the plug. If it still does
not Àt, contact a qualiÀed electrician to install the
proper outlet. Do not modify the plug in any way.

Preparations
Pack away after sewing
1. Switch the main switch off.
2. Unplug the cord from the wall socket and then
from the machine.
3. Unplug the foot control cord from the machine.
Wind the cord around the foot control for easy
storage.
4. Place all accessories in the accessory tray. Slide
the tray on to the machine around the free arm.
5. Place the foot control in the space above the
free arm.
6. Put on the hard cover.
Free arm
To use the free arm, slide off the accessory tray.
When attached, a hook keeps the accessory tray
locked to the machine. Remove the tray by sliding
it to the left.
Thread cutter
To use the thread cutter, pull the thread from back
to front as shown (A).
Spool pins
Your machine has two spool pins, a main spool
pin and an auxiliary spool pin. The spool pins
are designed for all types of thread. The main
spool pin is adjustable and can be used both in a
horizontal position (the thread reels off the spool)
and a vertical position (the thread spool rotates).
Use the horizontal position for normal threads and
the vertical position for large spools or specialty
threads.
Horizontal position
Place a spool cap and the thread spool on the spool
pin. Make sure that the thread reels over the top
and slide on a second spool cap.
Use a spool cap slightly larger than the thread
spool. For narrow thread spools, use a smaller
spool cap in front of the spool. For large thread
spools, use a larger spool cap in front of the spool.
The Áat side of the spool cap should be pressed
Àrmly against the spool. There should be no space
between the spool cap and the thread spool.

Preparations
Main spool pin in vertical position
Vertical position
Raise the spool pin to the vertical position. Slide
on the large spool cap and place a felt pad under
the thread spool. This is to prevent the thread from
reeling off too fast.
Do not place a spool cap on top of the spool pin as
that would prevent the spool from rotating.
Auxiliary spool pin
The auxiliary spool pin is used when winding a
bobbin thread from a second spool of thread or for
a second spool when sewing with a twin needle.
Raise the auxiliary spool pin. Slide on a large spool
cap and place a felt pad under the thread spool.
Threading the machine
Make sure that the presser foot is raised and the
needle is in the up position.
1. Place the thread on the spool pin and Àt a spool
cap of the right size.
2. Pull the thread into the thread guide (A) from
the front to the back. Pull the thread from the
right underneath the bobbin winder thread
guide (B) on the pre-tension disc (C).
3. Thread down through the right-hand
threading slot and then upwards through the
left-hand threading slot.
4. Bring the thread from the right into the take-up
lever (D) and down in the left-hand threading
slot to the needle thread guide (E).
5. Thread the needle.

Preparations
Needle threader
The needle threader allows you to thread the
needle automatically. The needle must be in the up
position to use the built-in needle threader. We also
recommend lowering the presser foot.
1. Use the handle to pull the needle threader all
the way down. The threader hook (G) swivels
through the needle eye.
2. Place the thread from the back over the hook
(H) and under the thread hook (G).
3. Let the needle threader gently swing back. The
hook pulls the thread through the needle eye
and forms a loop behind the needle. Pull the
thread loop out behind the needle.
Note: The needle threader is designed to be used for size
70-120 needles. You cannot use the needle threader for
size 60 needles or smaller, a wing needle, twin needle or
triple needle. There are also some optional accessories
that require manual threading of the needle.
Threading for twin needle
Replace the sewing needle with a twin needle.
Make sure that the presser foot is raised and the
needle is in the up position.
1. Place the thread on the spool pin and Àt a
spool cap of the right size. Raise the auxiliary
spool pin. Slide on a large spool cap and a felt
pad. Place the second thread on the spool pin.
2. Pull the threads into the thread guide (A) from
the front to the back. Pull both threads from
the right underneath the bobbin winder thread
guide (B) on the pre-tension disc (C).
3. Thread down through the right-hand
threading slot and then upwards through the
left-hand threading slot. Make sure that you
pass one thread to the left and one thread to
the right sides of the tension disk (D).
4. Bring the threads from the right into the
take-up lever (E) and down in the left-hand
threading slot. Make sure that one thread is
inside the needle thread guide (F) and the
other one outside. Make sure that the threads
do not become twisted together.
5. Thread the needles.

Bobbin winding
Winding from horizontal position
1. Place an empty bobbin on the bobbin spindle,
with the logo facing up. Use only the original
PFAFF® bobbins approved for this model.
2. Place the thread spool on the spool pin in
horizontal position. Slide a spool cap tightly
against the spool.
3. Place the thread into the thread guide (A) from
front to back. Pull the thread counter-clockwise
above the bobbin winder thread guide (B) and
then through the bobbin thread guides (C) at
the rear.
Note: Make sure the thread is pulled securely inside
the pre-tension device for correct thread tension.
4. Thread through the hole in the bobbin (D) from
the inside to the outside.
5. Push the bobbin lever to the right to wind. A
pop-up appears on the screen to inform you
that bobbin winding is active. Press the foot
control to start winding the bobbin.
When the bobbin is full, the bobbin winding
will slow down and stop automatically. The
pop-up closes. Remove the bobbin and cut the
thread using the bobbin thread cutter (E).
Winding through the needle
Make sure that the presser foot and the needle are
in the up position. Only wind through the needle if
using a metal presser foot.
Bring the thread up from the needle, under
the presser foot, upward through the left-hand
threading slot and through the bobbin thread
guides (C). Then follow step 4 and 5 above.

Preparations
Inserting the bobbin
1. Remove the bobbin cover by sliding it towards
you.
2. Place the bobbin in the bobbin case with the
logo facing up and the thread unreeling from
the left of the bobbin. The bobbin will then
rotate counter-clockwise when you pull out
the thread.
3. Place your Ànger on the bobbin to keep it from
turning as you pull the thread Àrmly to the
right and then to the left into the tension spring
(A) until it “clicks” into place.
4. Continue threading around (B) and to the right
of the thread cutter (C). Replace the cover. Pull
the thread to the left to cut.
Note: The bobbin cover can be used as a magnifying
glass.
IDT (integrated dual feed)
For sewing any fabric precisely PFAFF®
expression™ sewing machine provides the ideal
solution: the integrated dual feed, IDT system. As
on industrial machines, the IDT feeds the fabric
from the top and bottom at the same time. The
material is fed precisely. On light fabrics such as
silk or rayon the dual feed prevents puckering of
the seam. The even feeding action also ensures
perfect matching of checked and striped fabrics.
The IDT keeps all layers of quilt projects aligned to
prevent shifting of the top layers.
Engaging the IDT
Important: For all work with the IDT, use presser feet
with the center back cut-out (D).
Raise the presser foot. Press the IDT down until it
engages.
Disengaging the IDT
Raise the presser foot. Hold the IDT with two
Àngers at the ribbed ankle. Pull the IDT down, then
pull it away from you to release the IDT slowly
upward.

Preparations
Electronic knee-lift (4.0)
Your machine comes with an electronic knee-lift
for regulating the presser foot height.
Insert the knee-lift in the provided hole on the
machine. Adjust the rectangular bar on the knee-
lift (A) until it is positioned at a comfortable height
for you.
If you press the knee-lift to the right, the presser
foot will raise. You can now guide the fabric with
both hands.
To remove the knee-lift, just pull it straight out of
the hole.
Needles
The sewing machine needle plays an important
role in successful sewing. Use only quality needles.
We recommend needles of system 130/705H.
The needle package included with your machine
contains needles of the most frequently used sizes.
Universal needle (B)
Universal Needles have a slightly rounded point
and come in a variety of sizes. For general sewing
in a variety of fabric types and weights.
Stretch needle (C)
Stretch Needles have a special scarf to eliminate
skipped stitches when there is a Áex in the fabric.
For knits, swimwear, Áeece, synthetic suedes and
leathers. Marked with a yellow band.
Embroidery needle (D)
Embroidery Needles have a special scarf, a slightly
rounded point and a slightly larger eye to avoid
damage to thread and materials. Use with metallic
and other specialty threads for embroidery and
decorative sewing. Marked with a red band.
Denim needle (E)
Denim needles have a sharp point to penetrate
tightly woven fabrics without deÁecting the needle.
For canvas, denim, microÀbers. Marked with a blue
band.
Wing needles (F)
The Wing Needle has wide wings on the side of
the needle to poke holes in the fabric when sewing
entredeux and other hemstitches on natural Àber
fabrics. Decrease the stitch width for best results.
Note: Change the needle often. Always use a straight
needle with a sharp point (G).
A damaged needle (H) can cause skipped stitches,
breakage or snapping of the thread. A damaged needle
can also damage the stitch plate.
Do not use asymmetrical twin needles (I), since it may
damage your sewing machine.
