The needle thickness to be used for each machine and its sewing apparatus (E no.) is given on the nameplate. Yarns The appearance of the buttonhole is greatly affected by the yarn used. Synthetic-fibre yarns or even silk yarn can be used as the needle and bobbin threads.
3.2 Removing and replacing the clamp plates 1 23 1 Caution: danger of injury The clamp plates 1 must be removed and replaced with the machine switched off or in the “firm hold” position. Inadvertently operating the pedal with the main switch turned on may lead to damage or injury. Removing the clamp plates – Slightly raise the right or left (depending on the subclass) clamp plate 1 and remove it forwards. – Slightly raise the other clamp plate 1 and remove it forwards.
3.3 Changing the needle 1 2 3 Caution: danger of injury The needle must be changed with the machine switched off or in the “firm hold” position. 12 – Undo screw 1. – Pull the needle 2 out of the needle bar. – Push the new needle as far as it will go into the hole in the needle bar. – Align the needle 2 so that its throat points forward and the surface 3 on the needle piston to the left (in the direction of the attachment screw 1). – Tighten screw 1.
3.4 Threading the upper thread 1 Caution: danger of injury The upper thread may only be threaded with the machine switched off or in threading mode (see “threading mode” section). – Thread the upper thread as shown in the illustrations. – To thread the upper thread insert the threading wire (in the accessory kit) upwards through the hollow needle bar 1 from below. – Place the top end of the upper thread in the hook. – Pull the upper thread down with the wire.
3.5 Threading the bobbin thread 1 2 Caution: danger of injury The bobbin thread may only be threaded with the machine switched off or in threading mode (see “threading mode” section). The machine must be in its final position, i.e. the hook turret with loopers must point forwards. – Remove clamp plates (see section 3.2). 14 – Swing machine up. – Use the threading wires in the accessory kit to thread the bobbin thread as shown in the illustrations.
3.6 Threading the gimp thread (subclasses 579-121000, 579-141000 and 579-151000 only) 1 579-121000 and 579-151000 579-141000 Caution: danger of injury The gimp thread may only be threaded with the machine switched off or in threading mode (see “threading mode” section). – Thread the gimp thread as shown in the illustrations. – Leave about 25 mm of bobbin thread hanging out of the gimp hole in the throat plate.
4. Thread tension 4.1 Needle and bobbin-thread tension 1 2 3 4 The thread tensions depend on the type and quality of the yarn and material. The thread tension should be the minimum at which the appearance of the buttonhole is satisfactory. With thin material excessive thread tensions may cause unwanted gathering and thread breakage. Upper-thread tension The upper-thread tension must generally be set higher than the bobbin-thread tension.
4.2 Bobbin-thread-tensioning spring 1 2 3 4 5 1 Caution: danger of injury The thread-tensioning spring may only be adjusted with the machine switched off or in the firm hold position. The deflection and pre-tensioning force of the thread-tensioning spring 1 affect the bobbin-thread tension and thus the shape and purling of the buttonhole. Adjusting the deflection: – Undo screw 2. – Twist bracket 3. – Tighten screw 2. Adjusting the pre-tension: – Undo screw 5. – Twist bracket 4.
5. Changing the cutting blocks 1 2 The cut length can be changed by switching cutting blocks.
