I don't have a manual what are the tension for this machine
Difficult to address without knowing the make & model.
However, generally speaking, the standard factory setting for the upper tension is the midway point between the high & low numbers.
Bobbin tension is set at the factory and is tricky to reset by a novice. For the most part, it is recommended that the tension skrew setting on the bobbin case be marked with a permanent marker before any changes are made. That gives a reference point so that if it needs to be returned to the original setting, it is easier to do so. Make only 1/8 turns at a time and retest.
The correct tension is when the upper and bobbin threads meet in the middle of the fabric.
Keep in mind that the needle, thread, and fabric all impact tension. Before beginning a new project, test the tension first on a scrap of the fabric and get it set where you want it before sewing the project. That being said, tension (mostly upper thread) is static so it is important to get familiar with adjusting it to fit your project. One tension setting will usually not work for every project.
