  1. Using a doubled piece of fabric similar to what you have in mind for your project, sew a seam on the diagonal-pulling the fabric on the diagonal to break the threads. (Ideal tension would either break neither thread or break both threads. So, a single breaking thread signals that the tension needs adjusting.)
  2. Snap out the faceplate to remove it & to gain access the bobbin area below the sewing needle.
  3. Remove the bobbin case & bobbin-lifting the hinged latch that you would to wind a new bobbin-leaving the bobbin in the case. (You need it in there to feel the tension as you adjust it.)
  4. Using a small screwdriver, very slightly turn the screw on the side of the bobbin case clockwise to increase tension; counterclockwise to decrease tension.
  5. Pull the bobbin thread while you hold the bobbin in its case & feel the thread's tension. Too tight of tension would prevent the thread from dispensing (& possibly break), but too loose of tension would allow the bobbin to fall out of its case.
  6. Return the bobbin case to the sewing machine & close the faceplate.
  7. Repeat this whole routine from Step One on the doubled fabric. Stitching should run along both the top & the bottom in the same way-locking in the center. A diagonal pull of the fabric should show which thread(s) break(s). Repeat Steps Two through Four to only adjust the screw aside the bobbin case in order to allow the threads to lock in the center of the fabric with both threads having the same break or no-break result.

On this Singer Touch & Sew 638, while I am holding the bobbin case in position, when the handwheel is turned backwards the movement is smooth.


If this is a drop in bobbin case type, the black bobbin case may not be inserted correctly. Removal of the needle plate and proper installation of this part is a must, Damage to your machine can result if this is not properly remedied.

Why is the hand wheel so tights


It shouldn't be too tight. Clean out and remove the bobbin/bobbin case. Now, try to turn it. Does it turn any better? If it does turn easily without the bobbin case and bobbin installed you know the bobbin case was out of adjustment.
To adjust the bobbin case reinstall the bobbin case. Slightly move the hand wheel back and forth. There should only be slight movement of the bobbin case. The bobbin case is held in place by a small piece of metal next to the bobbin case.on the lower right corner. Just make the adjustment to prevent the case from movement.
The hand wheel can also be prevented from movement due to the interior parts of the machine being filled with dried greese. If you're feel safe about this you can remove the front, back, etc and inspect for buildup. Clean it up with carburetor cleaner and a qtip. Try not to douse the plastic gears with this. Clean it thoroughtly. Put sewing machine oil on all steel against steel movement. Any plastic movement should be done with a non petrolium product like silican spray. You can move the hand wheel a great deal to observe any parts that may have movement probmems.

Top tension suddenly loose in embroidery. Have rethreaded x 10


Make sure the bobbin case is seated properly without turning around. If you look there is a lever that holds it down on the left side. On the right side you will notice a holder that can be adjusted to tighten or loosen the movement of the bobbin. Leave a small amount of movement though because thread has to slide between areas.
The adjustment of the top tension is normal at four. Try to take a slight pull on this and pay attention to the feel of the pull. This is the amount of pull that the bobbin case should have the tension set. It is similar to a tug of war. The objective is to set the top and bottom tensions equally.

The bobbin thread shows to the front. Does the bobbin or thread tension need adjusted


Generally, tension adjustments are made using the upper thread tension. Most likely the upper tension is set too tight and is pulling the bobbin thread up. Loosen the upper tension and try again. Tension is accurate when the upper thread and bobbin thread meet in the middle of the fabric. Whenever fabric, thread & needle are changed, there may be a need to adjust the upper tension.

HINT: When threading the upper thread, make sure the presser foot is RAISED during threading to make sure the upper tension disks are open and the thread seats properly.

Bobbin tension is only adjusted when the tensions are way out of whack. Only slight turns of the bobbin case tension screw are made in graduated movements and testing occurs after each adjustment.

I have gone through 3 needles and I've never had an issue before. The machine ate my fabric and I pulled it out (big mistake) and now my needles keep breaking.


1. Put one drop of oil on race. The bobbin case has two screws to adjust to keep it from moving either clockwise or counter clockwise. You will need to adjust these. It is tricky but once in the right position it will only move slightly. Give just enough free movement to allow thread to fit through.
2. Adjust the bobbin tension. The screw on the bobbin will need to be adjusted so it has a tension which equals four on the upper tension. This is a little tricky but if you're off a little you can adjust the upper tension to correct this. NOTE: You are trying to adjust the upper tension and the bobbin tension to be equal. This is similar to a tug of war.
3. Try to turn the hand wheel. Watch to see if the needle thread will ride across the top of the bobbin. It should do this without the thread getting stuck. If it gets stuck you will need to adjust the bobbin case screws to allow a little more movement allowance.
4. Replace the needle.
5. If you still notice the needle striking something under the throat plate you will need to have your machine timed.

I have a Pfaff 4.2 Quilt Expression. I am free motion quilting and the bobbin thread keeps hanging up. Any suggestions?


1. The top loading bobbin cases have small brackets to keep them from turning or moving up or down.
2. Adjust brackets with small screwdriver. Allow enough room for thread to flow through.
3. Rotate hand wheel both directions to make sure the bobbin case doesn't move around. Also, watch the thread to see if it is flowing across the top of the bobbin case.
4. You may need to slow down movement of your "free motion". Also, make sure you are using the right pressure foot.

Bobbin Casing keeps coming out.


This machine has had 2 different updates for the bobbin case, the second also included a new bobbin visor and the metal bracket that holds the bobbin case in proper position. This sis located at about the 5 oclock position looking straight on at the machine. These new pieces must be adjusted and i am sorry the exact position cannot be explained. It must have just the right amount of movement between bobbin case and bracket. The bracket also must be positioned just right.

Bobbin thread is pulling to the top, using embroidery needle, bobbin thread and proper thread on the top. As far as I know the machine is set right. This might not be the right place to ask, but am...


Setting bobbin case tension:
Put wound bobbin in bobbin case. Thread it in case. Hold the thread and carefully let go of the case only holding bobbin thread. The case should NOT move. Quickly let your hand drop 2-3 inches to let the bobbin case free fall for 2-3 inches, the bobbin case should move slightly then stop. It moves because it let’s a little thread off the bobbin. It should then stop .5"- 2" of thread should release. If so, your bobbin case tension is right. If it’s right then begin to look at your top thread tension. Always Always start with a properly adjusted bobbin case, then adjust your top tension accordingly.

The bobbin case is most likely not adjusted properly. The bobbin case has a small piece of metal that can be loosened with a screwdriver. Once it is loose you need to move it to a point that won't allow the case to move. The bobbin case must only be moved to a point to stop the bobbin case from movement. If it is too tight it will cause the machine from sewing.
