Jakek1978 Report post Posted March 27, 2022 I just got my class 26 in the other day. I'm running into a problem where the stiching seems to be laying on top of the leather loosely. At first glance the stitch looks good. No high or low stitches. But they are loose. I believe that I need to increase the Bobbin tension, tightening it. Then I can adjust the upper tension. But apparently the class 26 has had a Bobbin upgrade since the last time they made their instruction manual. As soon as I can I'll send a picture of the new bobbin system. Has anyone come across this issue Quote Share this post Link to post Share on other sites
Constabulary Report post Posted March 28, 2022 well, the tension parts on sewing machines have not really changed significantly so I´m sure it is the balance between top and bottom tension you have to figure other than that make sure the top thread comes off the spool w/o hanging and nothing in the top thread path is causing drag or additional tension.
