Just get the Sp Swing a few days ago and I am having trouble string my POG OS? When I try to pull tension on the first Main, where the string is coming out of the throat, the angle keep pulling the racquet hand towards the gripper and I have to continuously push the racquet away to be able to get the tension to rise. Second the clamp keeps poping off when trying to tension this string. Is the anyway to make sure both clamps are tighten to the same level? Please help me, I've strung the racquet at least 100 before on and old stringer that had a linear gripper. But the was 10 years ago, I don't know why I am having so much trouble. PLEASE HELP, is it me or the machine?
