6 Operation 6.1 Threading the needle thread Caution! Risk of injury! Turn off the main switch. The needle thread may only be threaded with the sewing machine switched off. – Thread the machine according to picture.
6.2 Winding the hook thread 2 – – – – – – 6.3 1 4 3 Thread the thread according to the picture. Insert the thread under the knife 1 and tear off by pulling in the arrow direction 2. Fix the bobbin and press the lever 3 in the direction 4. Start the machine up. After the thread winding, slide the thread under the knife again 1 and tear it off. Insert another bobbin immediately and press the lever 3.
6.4 Adjusting the thread tension 6.4.1 Adjusting the hook thread tension 2 1 Caution! Risk of injury! Turn off the main switch. The hook thread tension may only be adjusted with the machine switched off. – – Adjust the hook thread tension via the screw 1. Increase the tension by tightening the screw. Measure the thread tension with a dynamometer. Thread the thread according to the picture and pull in the arrow direction 2.
6.4.2 Adjusting the needle thread tension 1 2 3 4 Adjusting the pre-tensioner 1 – Adjust the supplementary tensioner 1 so that it has the lowest tension possible, but so high that, when taking out the sewn material after the preceding trimming (when the tensioners 2 and 3 are switched off), the thread is not pulled out of the tensioner 1. (Tensioner 1 is not switched off at the foot lifting).
Correct thread interlacing in the center of the material Needle-thread tension too weak or hook-thread tension too strong Needle-thread tension too strong or hook-thread tension too weak 15
6.5 Switching on/off the thread tensioner 1 2 3 4 ECO and CLASSIC machines with electro-magnetic control – When pulling the hand lever 1 towards the operator, the tensioners 3 and 4 are switched off. – Tensioner 2 is never switched off. Manually controlled machines (without the thread trimming) – Tensioners 3 and 4 are mechanically switched off when the foot is lifted with a hand or knee lever.
6.6 Adjusting the thread regulator 2 1 1234 The thread regulator 2 controls the quantity of needle thread required for stitch formation. The thread regulator must be precisely adjusted for an optimum result. – Loosen the screw 1, shift the thread regulator 2, and tighten the screw 1. – For most of the sewing operations, the thread regulator optimal setting is with its right edge set to “2". – The setting “3" or ”4" is suitable for thin materials and very short stitches only.
