Bringing up the Bobbin Thread Hold needle thread slightly between thumb and forefinger of the left hand and turn flywheel with the right hand towards you, until take-up lever is about at its highest point. Then pull slightly the needle thread and the bobbin thread will come up. Pull both threads back under the presser foot, place material under same, lower foot and the machine is ready to sew. Fig. 12 Thread Tension The tension box is provided with a pointer and a demarcation line. When both form one line, then the tension is properly adjusted for ordinary sewing and darning and it will seldom be found necessary to make a change. Only for special works the tension may be changed by turning the tension nut. To increase the tension, turn the nut over to the right. To decrease the tension, turn the nut over to the left. For ordinary sewing set the pointer again on the demarcation line, as well as when the tension should have been changed for cleaning. 18 Suitable Needle and Thread For the portable machine model 125 use system 705 needles only. To obtain the best result of sewing, use first class needles and top-quality thread. First select the thread to suit the fabric, then the needle to suit the thread, according to the table below. The best test of suitability is to place the thread in the groove of the needle. If the thread fills the groove out and can be pulled backwards and forwards in it without obstruction, the needle is of correct size. For sewing, needles of sizes 8, 9 and 10 (80, 90 and 100) are usually employed, while numbers 7 and 8 (70 and 80) are used for darning.
