2500_DCE_2_englisch_neu 09.10.2007 15:02 Uhr Seite 73 Trouble shooting guide Problem: Cause: Solution: Seams pucker: Differential feed is set incorrectly. Adjust differential feed to 0.7 - N. Needle thread tensions are too tight. Reduce needle thread tensions. Looper thread tension is too tight for thread. Use the Deco Guide. Fabric edges curl: Too much fabric in the stitch. Reduce the cutting width. Stitch selection lever is on roll hem. Set selection lever to overlock. Thread loops are too loose. Too little fabric in the stitch. Increase the cutting width. Machine stops sewing: Should the machine stops sewing, the motor cuts out for 2 seconds, afterwards you can continue sewing. Check why the machine stopped. The machine will sew again after the safety cut out. Fabric cannot be removed: (cover stitch and top & bottom cover stitch) Handwheel was turned anticlockwise. Insert needles into fabric, press Needle stop, turn the handwheel away from you (clockwise) to raise needles. Remove work. 73
