Before sewing, please follow the arrow (1) of the drawing, and pull
down the extension table.
Extension table can help your fabric flow easier during sewing.
When the sewing machine is not being used, store the machine with
the extension table folded up.
If you don't need extension table, you can also easily take it off.
First, move the extension table slightly to the left, as the arrow (2),
to unhook the left side and then move it to the right unhooking the
right side (3). You can then take it off.

Accessory tray
Keep the snap-in accessory tray horizontal, and push it in the
direction of the arrow. (1)
Remove the accessory tray to sew cylindrical pieces such as sleeve
cuffs.
The inside of the snap-in accessory tray can be utilized to store your
accessories.
To open, lift up at the point of the arrow. (2)

Connecting machine to power source
Connect the machine to a power source as illustrated. (1)
The appliance is equipped with a polarized plug which must be used
with the appropriate polarized outlet.
Attention:
Unplug power cord when machine is not in use.
Foot control
Foot control regulates the sewing speed. (2)
Attention:
Consult a qualified electrician if in doubt as to how to connect machine to
power source.
Unplug power cord when machine is not in use.
The appliance must be used with the foot controller:
For USA and Canada, 110-120V: KD-1902
For Australia and Europe, 220-240V: KD-2902
Sewing light
Press main switch (A) for power and light on "l".
For USA and Canada
For appliance with a polarized plug (one blade is wider than the other). To
reduce the risk of electric shock, this plug is intended to fit in a polarized
outlet only one way. If it does not fit fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified electrician to install the proper outlet. Do
not modify the plug in any way.

Changing the light bulb
Disconnect the machine from the power supply by removing
the plug from the main socket!
Replace bulb with same type rated 10 watts (110-120V) or 15 watts
(220-240V).
- Loosen screw (A) as illustrated. (1)
- Remove the cover (B).
- Turn the bulb half a rotation counter clock-wise (C) (2) and
remove the bulb. Push the new bulb upward into the holder as
far as it will go and turn it half a rotation in a clock-wise direction
until it held firmly.
- Replace the cover and tighten screw.
Should there be any problem, ask your authorized Pfaff dealer for
advice.

Presser foot lifter
The presser foot lifter raises and lowers your presser foot. (A)
When sewing several layers or thick fabrics, the presser foot can be
raised higher for easy positioning of the work. (B)
Adjusting presser foot pressure
Standard presser foot pressure is set at "2".
The presser foot pressure of the machine has been pre-set and
there is no need for change unless sewing particular type of fabric
(light-or-heavy weight).
If you do need to adjust the presser foot pressure, turn the presser
adjusting knob as shown in the picture.
For sewing very thin fabric, loosen the pressure by turning the knob
counterclockwise. The knob will move upward and the pressure will
decrease. If you keep turning the knob, it can be taken out. By that
time, just turn the screw clockwise, until it lockes back in place and
readjust the pressure.
For heavy fabric, tighten the pressure by turning the knob clockwise
and the knob will move downward and the pressure is increased.
When the knob can not be moved any further, it has reached the
bottom. Please do not turn it any more.

10
Attaching the presser foot holder/presser foot/seam guide
Raise the presser bar (a). (1)
Attach the presser foot holder (b) as illustrated.
Attaching the presser foot
Lower the presser foot holder (b) until the cut-out (c) is directly
above the pin (d). (2)
Raise the lever (e).
Lower the presser foot holder (b) and the presser foot (f) will engage
automatically.
Removing the presser foot
Raise the presser foot. (3)
Raise the lever (e) and the foot disengages.
Note: You can use the standard foot for all stitches.
Attaching the seam guide
Attach the seam guide (g) in the slot as illustrated.
Adjust according to need for hems, pleats, etc. (4)
Attention:
Turn power switch to off ("O") when carrying out any of the above
operations!

11
Winding the bobbin
- Place thread and spool cap onto spool pin (1).
For smaller spools of thread place spool cap with small
side next to spool (2).
- Snap thread into thread guide (3).
- Wind thread clockwise around bobbin winder tension discs
(4).
- Thread bobbin as illustrated and place on spindle (5).
- Push bobbin to right (6).
- Hold thread end (7). Step on foot control (8).
- Cut thread (9). Press bobbin to left (10) and remove.
Please Note:
When the bobbin winder spindle is in "bobbin winding" position,
the machine will not sew and the handwheel will not turn. To start
sewing, push the bobbin winder spindle to the left (sewing position).

12
Inserting the bobbin
When inserting or removing the bobbin, the needle must be in
the highest position.
1. Insert the bobbin in the bobbin case with the thread
running counterclockwise direction (arrow).
2. Pull the thread through the slit (A).
3. Draw the thread clockwise until it slips into the notch (B).
4. Pull out about 15 cm (6 inches) of thread and attach the
bobbin cover plate. (C)
Attention:
Turn power switch to off ("O") before inserting or removing the bobbin.

13
Inserting and changing needle
Change the needle regularly, especially if it is showing signs of wear
and causing problems.
Insert the needle following the illustrated instructions.
A. Loosen the needle clamp screw and tighten again after inserting
the new needle. (1)
B. The flat side of the needle should be towards the back.
C-D. Insert the needle as far up as it will go.
Attention:
Turn power switch to off ("O").
Needles must be in perfect condition. (2)
Problems can occur with:
A. Bent needles
B. Damaged points
C. Blunt needles

14
Threading the upper thread
This is a simple operation but it is important to carry out correctly.
- Start by raising the needle to its highest point (1), and also raise
the presser foot to open the tension discs. (2)
Note:
For safety, it is strongly suggested you turn off the power before threading.
- Lift up the spool pin. Place the spool of thread on the holder
with the thread coming off the spool as shown. For small thread
spools, place small side of spool cap next to spool.(3)
- Draw thread from spool through the upper thread guide. (4)
- Guide thread around thread guide (5) pulling thread through pre-
tension spring as illustrated.
- Thread tension module by leading thread down right channel and
up left channel (6). During this process it is helpful to hold the
thread between the spool and thread guide (4).
- At the top of this movement pass thread from right to left through
the slotted eye of the take-up lever and then downwards again. (7)
- Pass thread behind the flat, horizontal thread guide. (8)
- Now take thread behind the thin wire needle clamp guide and then
down to the needle which should be threaded from front to back.
Pull about 6-8 inches of thread to the rear beyond the needle eye.
(9)

15
Thread tension
Upper thread tension
Basic thread tension setting: "4"
To increase the tension, turn the dial to the next number up.
To reduce the tension, turn the dial to the next number down.
A. Normal thread tension for straight stitch sewing.
B. Thread tension too loose for straight stitch sewing.
Turn dial to higher number.
C. Thread tension too tight for straight stitch sewing.
Turn dial to lower number.
D. Normal thread tension for zigzag and decorative sewing.
Please note:
- Proper setting of tension is important to good sewing.
- There is no single tension setting appropriate for all stitch
functions, thread on fabric.
- A balanced tension (identical stitches both top and bottom) is
usually only desirable for straight stitch construction sewing.
- 90% of all sewing will be between "3" and "5" ("4" is basic
setting).
- For zigzag and decorative sewing stitch functions, thread tension
should generally be less than for straight stitch sewing.
- For all decorative sewing you will always obtain a nicer stitch
and less fabric puckering when the upper thread appears on the
bottom side of your fabric.

16
Raising the bobbin thread
Hold the upper thread with the left hand. Turn the handwheel (1)
towards you (counterclockwise) lowering, then raising needle.
Gently pull on the upper thread to bring the bobbin thread up
through the needle plate hole (2).
Lay both threads to the back under the presser foot. (3)
