7. Operating 7.1 Switching on - Switching off - Safe stop 1 7.1.1 7.1.2 7.1.3 1 2 Switching on – – Switch on the main switch 1. Step the pedal back to reach the initial position of the sewing unit. The main menu appears in the display. – Switch off the main switch 1. All drives and the control are immediately separated from the mains. Switching off Safe stop The sewing unit has to be switched off or switched to “safe stop” before carrying out any work on it.
7.2 Threading in the needle thread Caution: Risk of injury! Switch the main switch off! Thread in the needle thread only with the sewing unit switched off. – – 10 Stick the thread reels on the thread reel holder and guide the needle thread and the bobbin thread through the unwinding arm. The unwinding arm must be positioned vertically above the thread reels. Thread in the needle thread as shown in the illustration below.
7.3 Adjusting the thread regulator 1 3 2 1 Caution: Risk of injury ! Switch the main switch off. Adjust the thread regulator only with the sewing unit switched off. With the thread regulator 3 the needle thread quantity required for the stitch formation is regulated. Only a precisely adjusted thread regulator guarantees an optimum sewing result. When the thread regulator is adjusted correctly, the needle thread loop must slide over the thickest spot of the hook with low tension. – Loosen screw 1.
7.4 Winding up the bobbin thread 5 1 4 – – – – – – 12 3 2 Put the bobbin on the bobbin winder 4. Pull the thread through the guide 2 and around the tension 1.
