I have a Pe150. Is she threading the bobbin correctly?
The directions for threading the bobbin are as follows.
1. Insert the bobbin into the shuttle following the thread direction as noted in the etching under the bobbin cove.
2. Guide the thread end around the finger through the channel toward the back. The channel is on the left hand side.
3. Close the bobbin cover by placing the left end in place and pressing down lightly on the right end to snap in place.
There is no need to pull up the lower thread, it is done automatically.
According to what I read in my manual all adjustments are made on the upper thread tension.
Tell her to contact brother for a manual.
