PERFORMANCE CHECK LIST
Whenever sewing difficulties are encountered, review the section in this instruction manual that details the operation you are performing to
make sure you are correctly using the machine. If the problem continues, the following check list may help you to improve the operation.
If you still have difficulties, contact your nearest authorized service center.
With the model STAR 240E and STAR 230E, you can use the sewing speed controller to adjust the sewing speed. When sewing at the slowest
speed, skipped stitches may easily occur depending on the type of thread and fabric used. If this occurs, sew at a faster speed.
