3 Operation 3.1 Needles, threads and gimps Needles Needle system: 558 / 579 Needle sizes: Nm 80-120 (558) / Nm 90-125 (579) according to the type of sewing thread, fabric and sewing equipment (E-No.). Attention! When changing over from one needle system to the other the distance between looper and needle and the adjustment of the needle protection have to be checked imperatively (see service instructions). Threads The look of the buttonhole is essentially influenced by the sewing thread used.
3.2 Removing and inserting the clamping plates 1 3 Caution: Danger of injury ! The removing and inserting of the clamping plates 1 has to be done with the sewing automat switched off or in the position “Threading mode” (see chapter “Threading mode”). Removing the clamping plate – Lift the right clamping plate 1 slightly at the rear and pull it to the back. Then remove the clamping plate to the right side. – Lift the left clamping plate 1 slightly at the rear and pull it to the back.
3.3 Changing the needle 1 2 3 Caution: Danger of injury ! The needle has to be changed with the sewing automat switched off or in the position “Threading mode” (see chapter “Threading mode”). – – – – – 12 Loosen the screw 1 (Allen key in the accessories). Pull the needle 2 out of the needle bar. Push the new needle as far as it will go into the hole of the needle bar.
3.4 Threading the upper thread 1 2 Caution: Danger of injury ! The needle thread must only be threaded in when the machine is switched off or in the “Threading mode” (see chapter “Threading mode”). – – – – – Thread in the needle thread as shown in the illustrations. In order to thread in the needle thread push the threading wire (part of the accessories) through the hollow needle bar 1 from the bottom to the top. Bring the needle thread behind the looper. Pull the wire with the needle thread down.
3.5 Threading the looper thread looper thread gimp thread Caution: Danger of injury ! The looper thread must only be threaded in when the machine is switched off or in the “Threading mode” (see chapter “Threading mode”). The automat must be in its final position, i.e. the looper turret with the loopers has to point to the front. – Remove the clamping plates (see chapter 3.2). – Swivel the automat upwards.
3.6 Threading the gimp thread looper thread gimp thread Caution: Danger of injury ! The gimp thread must only be threaded in when the sewing machine is switched off or in the “Threading mode” (see chapter “Threading mode”). – – – Thread in the gimp thread as shown in the illustrations, depending on the subclass. With the Subclass -141000, -341000: thread in the gimp as shown in illustration A. Leave a gimp end approx. 25 mm long hang out of the gimp hole of the stitch plate.
4 Swivelling the automat up and down Caution: Danger of injury ! The automat must only be swivelled up when the machine is switched off or in the “Threading mode” (see chapter “Threading mode”). 1 For various operations (e.g. for threading the looper thread or the gimp thread) the automat has to be swivelled up. Swivelling up: – Pull the locking bolt 1 and lift the automat at the front.
5 Thread tension 5.1 Needle thread and looper thread tension 1 The thread tensions are dependent on the type and quality of the threads and fabrics. The buttonhole looks best if it is sewn with the lowest possible thread tension. Too tight thread tensions can lead to undesired ruffling and thread breakage, particularly when processing thin materials. Needle thread tension In general the needle thread tension has to be tighter than the looper thread tension.
1 Looper thread tension – Swivel the machine head up. – Adjust the looper thread tension by means of tensioner 1. Turn the tensioner in clockwise direction in order to increase the looper thread tension. Turn the tensioner counter-clockwise in order to reduce the looper thread tension. – Swivel the machine head down. Caution: Danger of injury ! The looper thread tension must only be adjusted when the machine is switched off or in the “Threading mode” (see chapter “Threading mode”).
