Before changing the tension settings, be sure to thead the machine with the presser foot up as this also has a tremendous effect on the tension and formation of the stitch.

How do I set the bobbin tension


How to change the tension on a sewing machine?
Adjust your top tension if it's too tight. To decrease your top tension if it is too tight, turn your knob so the numbers are decreasing. Try ½ to 1 number lower, then test the stitches on a piece of scrap fabric. Continue until it looks even on both sides and you can no longer see the bottom thread on the top.

Tension of pe770


Besides the other advice here, check your bobbin case. At first I didn't get my thread hooked into the bobbin case properly and had problems that looked like the bobbin tension was not adjusted properly. I have to take the case out, put in the bobbin to make sure it's caught properly and then put it back into the machine. This is what worked for me.

My bobbin thread keeps looping and the top looks fine but pulls out easily. I tried adjusting the top tension, but it didn't help. What can I do?


There could be several things that could cause the machine not to pick up the bobbin thread.


1. The upper thread could be tangled. Remove the thread completely from the machine. The correct size spool cap should be used for the size of the thread spool. Re-thread the machine according to the directions in the manual.


2. Remove the bobbin and make sure the bobbin is threaded properly in the shuttle race. Remove any loose threads or lint in the shuttle race.


3. You could be holding the needle thread too tight. Hold the thread lightly to keep the end from going down into the shuttle.


4. The needle could be thread incorrectly. Thread the needle eye from the front to the back.


5. The needle could be bent or improperly inserted. Install a new needle with the flat side of the needle facing the back.


If the problem persists, your machine may require service.



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.

How do i adjust the bobbin tension on a tesco ej09 sewing machine? The bobbin thread keeps tangling underneath the material


Before adjusting the bobbin tension (small screw on the side of the bobbin case), try this.

Always thread a sewing machine with the presser foot up as this opens the tension control for the top thread so the thread can be properly seated for control when stitching.

Often what appears to be a problem with the bobbin thread is actually the top thread going loosey-goosey.

The top thread is really loopy on the underside of the fabric, sometimes it misses a stitch, sometimes, the upper thread breaks, and it often gets so tangled underneath that the machine won't feed.


Your tension is way too loose on top or too tight on the bobbin. Try adjusting the top tension one number at a time until you get it right. (Only adjust the bobbin tension as a last resort). Also you could have different thickness of thread in the bobbin than on the top or are sewing a very heavy fabric. Try adjusting the tension with same thread in both bobbin and top and use a normal weight fabric until you find the right tension to get you back to a normal stitch before going to a heavier fabric or thread.

Difficulty adjusting tension to avoid bobbin looping


it sounds like your bobbin tension is too tight. to adjust bobbin tension, remove bobbin case (remove needle plate first) and adjust bobbin tension screw on side of case until bobbin thread has a slight resistance as you pull it through the bobbin case.

this will be trial and error until you get best result. you should always try and match top and bottom threads. if the top thread is quite thick you may have continue to increase needle thread tension until balanced.

Kenmore 15343 incorrect stitching


When you see the bobbin thread on top of the fabric this can be on e of 2 things usually. 1) thath the top thread tension is too tight or that the bobbin thread loose. Remember the saying righty tighty, lefty loosey. If you have adjust the top tension and it has helped just not enough perhaps you need to try the bottom a small screwdriver to turn the little screw on the outside of the bobbincase may do the trick. only small adjustments 1/4 turn at the most at a time to the right to start with.
