SOURCE: bobbin thread won't catch with needle thread
check that the needle is in the right way round i.e. with cut out on the needle facing into the machine. if this is fine then check that as the needle comes back up from the lowest point that it goes to, that the point on the bobbin case passes just above the hole in the needle, i.e. in the middle of the cut out.(if not it needs re timing) if threaded a small loop should appear at this point for the bottom bobbin to catch if not slacken the top thread and try again.

The bobbin thread tension
has already been adjusted at the factory for general use. For most
applications, no adjustment is needed.
When sewing with then
thread on thin fabrics, the thread tension may not be adjusted adequately with
the upper tension control dial. Therefore, the thread tension must be
adjusted according to the procedure described below.
If bobbin tension is too
loose and locks appear on the surface of the fabric, decrease the thread tension
by turning the dial to a lower number.
If the result is still
not satisfactory, then adjust the bobbin thread tension.
Increase the tension in the bobbin by turning the screw with a small screwdriver in a clockwise direction. However, do not turn the screw more than one full turn.
