4.1 Check before starting to sew
In order to start a project successfully, the following steps must be performed:
• The machine is switched on and the presser foot is lifted.
• The fabric and the applications have been selected. (see page 61)
• The thread has been selected.
• The needle size is matched with the thread type and the sewing project.
• The stitch is selected.
• The machine settings based on the stitch selection have been performed. (see page 73)
• The threading has been perfomed.
• All needle threads and looper threads lie under the presser foot to the back left.
• The looper cover and the threader cover are closed.
> Lower the presser foot.
> To start the sewing process, press the foot control.
– A thread chain is formed.
– If no thread chain is formed, the settings on the machine for the stitch must be checked.
4.2 Selecting the fabric
The choice of fabric, in combination with needle, thread and stitch, plays a vital role in achieving the perfect
sewing result. The sewing test with the selected fabric is recommended. (see page 98)
4.3 Selecting the thread
A wide range of sewing and special overlock threads are manufactured in various sizes and in different fiber
combinations.
• The use of high quality overlock thread is recommended to achieve good results.
• Use thread cones/spools which are suitable for overlock machines.
NOTICE
Thread breakage due to incorrect needle/thread or thread/looper matching
The thread needs to glide smoothly through the respective thread guides.
It must be possible to feed the thread through the looper or the needle eye without any resistance.
Thread thick decorative threads exclusively into the loopers, use the air threader circumvention if necessary.
In the case of thick threads, elongate the stitch length and reduce the thread tension.
