[. . . ] Keep the ventilation apertures of the machine and the foot switch free from fluff, dust and waste material. â· Should the cable connected to the foot pedal become damaged, to avoid potential risks it must be replaced by the manufacturer, his customers services or a similarly qualified person. Do not wear loose clothing or jewellery, as these can be caught in moving parts. If accidents occur as a result of handling the machine with insufficient care, or failure to follow the safety instructions in this manual, then the manufacturer cannot accept liability. [. . . ] When yarn has been threaded for the first time, or after a yarn breakage it must be rethreaded, proceed as follows: further thread routing 3. Guide the yarn, as shown, from front to back through the eyes of the needles. Hold the ends of the threads between the fingertips of your left hand, slowly turn the handwheel 6 two or three times towards yourself and then check the threads once again. The thread tension required is variable, being dependant itself on the type and thickness of the thread and fabric. check the seams and then adjust the appropriate thread tension on the machine. Tensioning the thread When you turn the tensioning device to a lower number, the tension reduces. When you turn the tensioning device to a higher number, the tension increases. Lay the material for a trial run under the sewing foot o and slowly start to sew. When the task is complete, continue sewing until an approximately 5cm (2") long length of threads has formed at the end of the material. The most appropriate thread tension adjustment for one type of material is not necessarily the ideal adjustment for a different material. The thread tensions required are dictated by the pliability and thickness of the material as well as the type and thickness of the thread. When necessary, adjust thread tensions as per this table: Thread tension adjustment With the following procedure, changing threads is quite simple: 1. Cut the yarn above the spindle and knot the ends of the new and the old thread together. Pull on the other end of the yarn until the knot passes under the sewing foot o. For threading it in the needle, pull on the other end until the knot is in the eye of the needle and then cut the yarn to the left and right of the knot. Turn the handwheel 6 towards yourself until the needles are in the lowest position. The free arm 0 lowers itself and the adjustment wheel for the cutting width i can be seen. Continue turning it until the looper threads are lying at the edge of the material. Turn the handwheel 6 towards yourself until the needles are in the highest position. Loosen the setscrew against the needle with the Allen key from the accessories box and then remove the needle: - upper left setscrew for the left needle - lower right setscrew for the right needle. For this, turn the adjustment wheel for cutting width i to the right (N). Select a larger cutting width if the yarn is being sewed beyond the material edge. [. . . ] Always remember to return the adjustment for the sewing foot o from this special to normal operation (sewing tasks) after the sewing of hems. With the differential feed motion uneven seams are avoided in knitted materials, as well as the slippage of textile positions. The machine has two sets of toothed rack feeders, one to the front and one to the rear. ALWAYS remove the plug j from the mains power socket before storageing the machine. [. . . ]
