  • Page 20: Notes On Usage

    Notes on usage Needles and threads By selecting the most suitable needles and threads for the relevant sewing material one can influence the sewing quality decisively. Only tested GROZ-BECKERT needle system 1717 VRUE should be used. The machine is supplied with needles of thickness 90/14. NOTE: An intact needle is of decisive importance for a good initial stitch.

  • Page 21: Threading And Thread Run (Fig. 6)

    Threading and thread run (Fig. 6) C A U T I O N ! Danger of injury! Switch off the machine prior to threading and ensure the machine is off by pressing the pedal for switching the motor. Fig. 6 shows the correct threading by using the thread sensor. Fig.

  • Page 22: Winding Up The Thread (Fig. 7)

    Winding up the thread (Fig. 7) The course of the thread during winding up is shown in Fig. 7. Care must be taken that not too much of the thread is wound onto the bobbin and that the bobbin walls are not pushed apart, faulty bobbins must immediately be replaced with new ones.

  • Page 23: Thread Tensioning

    Fig. 8 Thread tensioning 4.5.1 Thread tensioning - needle thread (Fig. 9) Depending on the quality, configuration and thickness of the thread as well as the sewing material, the thread tension is set using the locking sleeve (1) (Fig. 9) to the desired seam diagram.

  • Page 24: Thread Tensioning - Bobbin Thread (Fig. 10)

    4.5.2 Thread tensioning – bobbin thread (Fig. 10) The leaf spring (2) regulates the bobbin thread tension. By turning the flat-head screw with catch (1), the leaf spring must be adjusted in such a way that when the bobbin is inserted, and the thread is correctly pulled under the leaf spring and the bobbin case is released, the latter, together with the bobbin drops slowly down.

  • Page 26: Stitch Depth

    Stitch depth Stitch depth means the distance between the highest plunger position and the outer radius of the needle. The plunger forces the sewn item from underneath into the Stitch plate opening, so that the needle penetrates the layers of material to the desired depth.

  • Page 27: Digital Stitch Depth Display (Fig. 12)

    4.7.2 Digital stitch depth display (Fig. 12) The plunger height can be read off digitally from the stitch depth display. This makes finding earlier adjustments substantially easier by frequently changing sewing material thickness. The current supply is via a 9 V battery in the housing. To prevent premature discharging of the battery, the display should be switched off with the toggle switch at the housing during longer work breaks and when finishing work.

  • Page 28: Plunger Stop

    Plunger stop Frequently it is necessary when trimming fabric to sew over different fabric thicknesses at the same work piece, whereby the penetration depth of the needle, viewed from the upper side of the sewing material, must always remain the same. The plunger built- into our machines carries out this work automatically in cooperation with an adjustable plunger stop mounted on the stitch plate.
