Instructions for assembling
1) The standard setting of the machine for the category 3 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) 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.
4) 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 4.8.
5) 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.
6) 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.
