Report "I have a Consew 817 Blind Stitch machine and I do not have a manual. Do you have any resources to purchase one. Also I have constant problems with breaking stitches when I sew. How can this be fixed? I have tried to adjust the tension but I am never able to get it just right. I have also changed needles and lubercated, but this dose not seem to help. I sew draperies and this problem makes it impossible for me to use this machine. Thank you I will look forward to hearing from you"
