When a sufficient amount of thread has been wound on the bobbin, a latch stops the bobbin winder. The amount of thread to be wound on the bobbin is regulated by screw 6.
Turn this screw clockwise for more thread, or counter-clockwise for less thread. If the thread should pile up at one end of the bobbin, adjust the position of the bobbin winder tension sideways, as may be require d.
To do this, loosen screw 7, adjust the tension and tighten the set screw again. The tension on the thread is regulated by turning nut 6.

Lay both threads back under the presser foot, place the material in the machine and lower the presser foot. Hold the ends of both threads until the machine has made a few stitches. If the upper tension is too loose, the bobbin thread will draw the needle thread down so that it forms small kinks on the underside of the material, as shown in Fig.
If the upper tension is too tight, the bobbin thread will be pulled up Fig. Both tensions are correctly balanced, if the needle and bobbin threads interlock in the center of the material, as shown in Fig. To do this, pull the work back in for ward feeding direction , never forward as this may cause bending of the needle, skipping of stitches or thread breaking.
Take the bobbin case out of the machine and regulate the tension by turning screw Z, Fig. Turn this screw clockw ise for a tighter tension, or counter-clockwise for a looser tension. If puckering occurs on delicate materials although the tension has been set correctly, as both tensions slightly. Turn this nut clockwise for shorter stitche s, or counter-clockwise for longer stitche s. The numbers on the left of the scale indicate the stitch length in millimeters.
