1. General Hints
Read this manual carefully and perform every movement on
the sewing machine. One should never use force. To lubricate
them, only use the prescribed sewing oil. Good results can
only be obtained if you use the needles prescribed for this
machine (see article 10).
If the machine should no longer run properly due to the
passage of time or due to improper handling, one should not
call in some mechanic, but go to our representative where
this machine was bought. He knows them best and has an
interest in keeping them in good order.
Shuttles, bobbins and other parts must always be purchased
from our representative.
2. The Drive Belt
When the packaging is removed from the machine, place the
belt in the belt slot of the flywheel and pass it through the
holes in the table top around the axis of the undercarriage
flywheel, then hook it together and turn the wheel one or
more times around.

shortened proportionally.
3. Disengaging the Mechanism
If the knob "a" is turned in the direction of the arrow 1 (hold the
driving wheel), the mechanism is switched off. If the knob "a" is
turned in the direction of the arrow 2 (hold the drift wheel), the
mechanism moves with you when you pedal.

4. Treadle Exercise
Figure 1
3a. The Handcrank
The handcrank is only supplied with hand or treadle machines on
special order. It is attached behind the arm of the sewing machine
and is connected to the machine by a pawl "a" which engages in the
spokes of the wheel. By pressing a finger on "a", from the inside
out, the connection with the wheel can be broken again. The wheel
must be turned in the direction of the arrow. The crank 5 is held by a
spring-loaded pin 4 and is closed by retracting the pin-knot 4

One should pay attention to the noise the machine makes
when it is running. The size of the kick should not
dominate.The tone of the machine should be a regular
whirring tone.
5. Removing the Shuttle
The sliding plate "c" (Figure 3.) is opened by turning the gear
wheel and the shuttle is brought into the forward position to
see exactly the places and how the thread has been inserted.
This will be useful in the following exercises.

The regular stitch plate should be exchanged with the small
hole stitch plate, which is provided when sewing with a thin
needle and thin thread.
When inserting the stitch plate, make sure that the needle is
positioned exactly in the center of the hole in the plate.

The cause can be:

a) that the machine has been twisted due to improper
handling,
b) the needle is bent, too low, or misplaced,
c) the thread is too thick, the needle is too fine.

a) the bobbin is wrong and set, so that the thread is pulled
away in the wrong direction,

The Wide Hemmer
Then the fabric is laid out, the seam is smoothed and the lace
that is now formed is passed one more time through the
sewing machine to sew it flat.
It is used for hemming very thick fabrics or two fabrics at
once. The use is exactly as described above. Also beautiful
seams can be achieved with the broad seamer, as described

At the highest position of the needle, the presser foot with
the screw is removed. Then the conveyor rod is lowered so as
not to preclude the tension of the upper thread. In order to
be able to manually control the movement of the embroidery
frame when embroidering and darning and thus change the
length and direction of the stitches as necessary, the needle
plate is exchanged for the embroidery stitch plate (see Fig.
19).

make sure that the seam in question is guided exactly along

The fabric that one wants to darn or embroider is stretched in
an embroidery frame and then it is smoothed out. If the

finer than by hand. After the necessary threads have been
drawn out, at the simple open seam the threads that remain
are tied together at the edge by means of cross-stitching. The
order of the stitches is shown by the arrows on 25. If the
threads are gathered in the middle, one goes ahead with a
normal stitch and summarizes the necessary number of
threads with grappling stitches. If you want to create a special
embellishment, you can draw another wave-shaped sewing
stitch through the open seam when it's finished.
Embroidery
The fabric is first sewn with small stitches and then cut out
according to the pattern. Then begin the lace stitch and draw
the longitudinal seams in equal distances over the cut fabric,
moving the steps and the fabric back at the same time, after

needle without an eye must be used, which can be obtained
from the dealer or the manufacturer.
