4.9.2 Seams with blind stitches
In situations where no previous experience has been gathered, use one of the
two settings:
1. Set the desired stitch length.
Figure 8 displays the corresponding seam
shape for the required stitch length.
2. Set the stitch depth.
3. Check the cloth retainer pressure and adjust it if necessary.
4. Adjust the presser stop.
5. Adjust the material guide as desired. To do this, loosen the knurled screw
((2) figure 2) and move the material guide to find the limit for the edge of the
seam.
Sewing can be performed along the edge or directly on the seam. For more,
see
figure 9
6. Check the stitch length; if necessary readjust the transporter.
7. Adjust the thread tension. As a rule, the seam should lie loosely on the seam.
8. If desired, switch on the interval and set the interval stroke according to the
required thickness of sewing material.
9. To correct the seam shape, thread in at a different spot if necessary.
Insert the sewing material and ensure that the start of the seam can be caught
by the transporter after the first stitch.
Press the pedal briefly. Sew the part and, if required, changes the previous
settings until the desired sewing results are achieved. When stitching through
the outer material, readjust the stitch depth control.
On extremely thin or hard sewing material, it may not be entirely possible to
prevent “markings” caused by the insertion of needles into the outer material
(filament displacement).
When sewing, ensure that the edge of the seam always runs along the material
guide. Avoid sudden actuation of the pedal since the speed changes can have
a negative effect on stitching during the sewing process.
