  • 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 1828 E should be used. The machine is supplied with needles of thickness 80. Note: An intact needle is of decisive importance for a good initial stitch.

  • Page 23: Winding Up The Thread (Fig. 8)

    Winding up the thread (Fig. 8) The course of the thread during winding up is shown in Fig. 8. Care must be taken that not too much of the thread is wound onto the reel and that the reel walls are not pushed apart, faulty reels must immediately be replaced with new ones.

  • Page 24: Thread Tensioning (Fig. 6)

    Fig. 9 Thread tensioning (Fig. 6) Dependent on grade, characteristic and thickness of the thread as well as the sewing material, the thread tensioning is adjusted to the required seam diagram with the tensioning nut (3). 4.5.1 Thread tightening spring – needle thread (Fig. 10) The tension of the rotary spring (1) can be modified after releasing the grub screw (2) and by turning at the headed bolt (3).

  • Page 25: Thread Tensioning – Reel Thread (Fig. 11)

    4.5.2 Thread tensioning – reel thread (Fig. 11) 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: Adjusting The Upper Feed Path (Fig. 6)

    Fig. 12 4.6.1 Adjusting the upper feed path (Fig. 6) By activating the right pedal the upper feed path is enlarged, that is, multi-width can be worked in. By turning the knurled screw (1) to the left, multi-width can be worked in continuously.

  • Page 27: Stitch Depth

    Stitch depth By stitch depth one understand the distance of the highest plunger position to the outside radius of the needle, the plunger presses the sewing material from underneath in the stitch plate opening, so that the needle stitches into the fabric layers at the required depth.

  • Page 28: Digital Stitch Depth Display (Fig. 13)

    4.7.2 Digital stitch depth display (Fig. 13) 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 29: 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.

  • Page 30: Interval Gear

    Fig. 14 Interval gear The interval 1:2 or 1:3 guarantees an elastic seam almost free of marking with extremely difficult to work fabric qualities. The principle of the interval is based on the repeat of a different plunger height, which always remains the same with the individual penetrations of the needle. We use it with two different machine types: Needle lever with radial movement.

  • Page 31: Seam Lock

    4.10 Seam lock A t t e n t i o n ! Switch off machine electrically! A t t e n t i o n ! Danger of finger bruises in the area of pneumatically operated parts. General 4.10.1 The sewing cycle begins with the point tack by pressing the pedal forwards.

  • Page 32: Operating The Sewing Machine

Otherwise there is a danger of injury through crushing and needle through-stitches. For machines with 2 pedals: push down the left pedal fully increases the top feed length (multi-width take-up).

  • Page 33: Inserting And Removing The Sewing Material

    Sewing The lining (with cl. 310D-R) or the fabric hem (with cl. 3100D-R half lined working) will be inserted in the left stitch plate opening standing up. In both cases it is advantageous to tack or to peg with hairpins.

  • Page 34: Hemming With Blind Stitch

    5.3.1 Hemming with blind stitch If there are no experience values available, the best thing to do is to carry out the following settings in sequence: Adjust required stitch length Adjust stitch depth Check plunger stop and if necessary adjust Adjust material guide (if available) Check presser plate lift.

  • Page 35: Problems During Sewing And Troubleshooting
