Loose studies on underside?

Brother sewing machine problems with understiching -is it a tension problem?
Vanner, May 2011
Hello Vanner,
Yes it is, make sure the top tension is about 4 or 5 and use only mercerised thread, if the bottom tensionm is too tight slacken the screw about a quarter of a turn on the bobbin case.
