14 Thread tension settings Set the thread tension to suit the type of fabric and thread used. As the number on the thread tension discs increases, the thread tension becomes tighter. Lower looper thread and upper looper thread should be well balanced with the same tension (both looper threads should cross at the edge of the fabrics). Needle threads[...]

15 Differential feed adjustment The differential feed system consists of two sets of feed teeth arranged one behind the other. Both feed teeth work independently of each other to give perfect results when sewing on speciality fabrics. When the amount of feed by the front feed teeth is changed in relation to the feed by the rear feed teeth it will ?[...]

16 Presser foot pr essure adjustment The presser foot pressure is pre-set for sewing based on normal conditions. Adjustment might in some conditions be necessary. Increase or decrease the pressure until you are satis À ed with the result. Always test sew on a sample of your fabric before sewing on your garment. Less pressure: Decrease the pressure[...]

20 Machine maintenance An overlock requires more frequent maintenance than a conventional machine for two reasons: - A lot of lint is produced when the cutters are cutting the the fabric. - An overlock runs at a very high speed and needs to be oiled frequently to lubricate the internal working parts. Cleaning Turn off the main power switch and unpl[...]
