Presser Foot Pressure; Thread Tension - Singer C240 Manual De Instrucciones

Presser Foot Pressure

The presser foot pressure has been pre-set to the
adjust the presser foot pressure. When using specialty
fabric, adjusting the pressure can help improve the
result.
For very light fabrics, loosen the pressure by turning the
dial counterclockwise.
Note: If the dial is turned counterclockwise too much, it
could come off. If this happens, simply replace the dial
and turn it clockwise until it stays in place.
For heavy fabric, tighten the pressure by turning the dial
clockwise.
Note: If the dial is turned clockwise until it comes to a
stop, it has reached the maximum pressure available. Do
not try to turn the dial any further!

Thread Tension

To set the thread tension, turn the dial on top of the
machine. Depending on the fabric, thread, etc, the
tension may need to be adjusted.
For the best stitch appearance and durability, make
sure the needle thread tension is correctly adjusted. For
general sewing, the threads evenly meet between the two
layers of fabric.
If the bobbin thread is visible on the top side of the
fabric, the needle thread tension is too tight. Reduce the
needle thread tension.
If top thread is visible on the underside of the fabric, the
needle thread tension is too loose. Increase the needle
thread tension.
For decorative stitches and buttonholes, the top thread
should be visible on the underside of the fabric.
Make a few tests on a scrap piece of the fabric you are
going to sew and check the tension.
