CrossFireLaser Report post Posted April 16, 2020 (edited) We recently bought a very nice used CB 3200 a few months ago and when we first got it, it was sewing everything, thick and thin with almost no adjustment. Recently the tension has gotten out of whack and the top tension appears to be too tight, while the bottom tension is too loose. Despite having every point loosened up top and the bobbin tension being tightened. Attaching a picture of the problem. Does anyone have any ideas to remedy this problem? We are normally sewing on lighter leathers. Edited April 16, 2020 by CrossFireLaser Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted April 16, 2020 If adjusting the tensions doesn't solve knots on the top, check the thread from the spool to the needle for binding. It could be windings cross feeding, or dropping under the spool, or twisting around posts and guides. You should raise the feet manually and pull on the thread before the needle. If it is jammed somewhere, it will be hard to pull and you can follow the path until you see the problem location. If the top path is not binding, check the bobbin to make sure the bobbin thread is actually coming out under the tension spring and that tension is being applied to the thread.
