Insert the cloth under the presser foot up to the edge of the upper cutter and start sewing slowly. b. Thread tension adjustment (Normal hemming) The correct thread tension varies depending on the fabric and type and thickness of the thread and must therefore be adjusted accordingly.

By following this instruction, very good sewing results can be achieved. How to replace the presser toot 1.Raice the presser foot and then push up the small lever. The foot for normal sewing can then be taken off. 2. With the presser foot still raised, place the roll hemming foot under the shank and lower the shank until connecting points are in contact, then lower the presser foot and the new foot will then be engaged.

21 E. Sewing problems and solutions Used correctly, your machine should operate efficiently and without difficulty. However you may from time to time encounter the occasional problem which usually results from not carrying Out various adjustments in the recommended manner. Listed below are the more common problems, together with their simple solution which should overcome most of these difficulties. Problem Cause Solution Needle breakage Needle is bent or point damaged Insert new needle. Needle not correctly inserted Insert new needle correctly. Material pulled Do not pull or push material during sewing. Thread breakage Incorrectly threaded Thread correctly. Thread has caught Check whether thread is caught at the reel stand, etc. Thread tension too tight Needle not correctly inserted Incorrect needle used Regulate tension. Insert needle correctly. Use needle system 130 / 705H only. Skipped stitches Needle bent or damaged Insert new needle. Needle not correctly inserted Insert needle correctly. Incorrect needle used Use needle system 1 30 / 705H only. Incorrectly threaded Thread correctly. Incorrect stitch Incorrect setting of thread Set thread tensions correctly. formation tensions Puckered seams Thread tension too tight Reduce thread tension Thread has caught due to Thread correctly incorrect threading Material is not fed Sewing foot is not in the working Push the presser foot lever down. correctly position 20
