1) The standard setting of the machine for the categories 3 and 4 concerns a decorative stitching, when it is difficult to match
a good stitch interlocking with a faultless function of the thread trimming device. Otherwise, when sewing material of
considerable overall thickness, it will be necessary to increase the overtopping of the teeth above the needle plate and to
increase also the needle thread tension.
2) The thickness of a layer is measured using an engineer slide calliper with the pressure of jaws of about 10 N.
3) If the user will agree with the maximum stitch length of 5 mm, the pin of the feeding lever can be left in the position 1.
4) The values of tension are only orientative ones and it is necessary to adapt especially the tension of the hook thread
according to the stiffness of the material. An excessive tension of the threads when sewing soft materials causes material
wrinkling.
5) When performing decorative sewing, it is possible to use the hook thread having the label No 20 - the interval between the
two replacements of the hook bobbin will be double.
6) When changing markedly the sewing category together with changing the tension of the hook thread, it is necessary to
modify the tension of the retaining spring of the trimming device according to the paragraph 4.7.
7) When changing markedly the sewing category together with a marked change of the needle number, it is necessary to correct
the setting of the distance of the hook from the needle, according to the paragraph 3.1.3.
8) There are in use various types of feeders with the purpose of avoiding imprinting the teeth in the lining leather. Otherwise, it
is possible to use any feeder.
9)
The splice with the so-called spur may be used with the sewing categories 100 and 200 and is designed for sewing thin
materials.
In the production factory , the gib without spur is mounted as standard.
When using the gib with the so-called spur, we recommend carrying out the setting of the pin of the thread mechanism (par.
3.2.4) for the sewing category 400.
