I would like a copy of the manual for this Singer 7102 machine if anybody has one they can scan for me. If anybody has any spare parts or accessories they don't want -- that would be nice too as the machine I have been given did not have the accessories with it. Currently it sews but the tension is obviously not working as it tangles up on the underside of the fabric. I may have it threaded incorrectly or it may have another problem.
