Manual backtack lever works but electronic servo backtack only engages when machine is at rest with needle in up position.

The 7462 and the related machines can do this when the buttonhole lever is down. This lever is behind the needle bar on the back of the sewing machine. Make sure this lever is fully up by pushing it with your finger. Then use the hand wheel to bring the needle to the highest position in its travel path. Make sure that the bobbin winding spindle is to the far left position. The manual is available from Singer. The current link to the manual is https://res.cloudinary.com/singer-sewing/image/upload/fl_attachment/Singer-Website-Library/outdated_product/SINGER_7462_Sewing_Machine.pdf . See page 7 to see the button hole lever position. It's labeled 17 on the diagram of the back of the machine.

If the problem persists, you may have a problem with the hardware for the bobbin winder. The spindle has to lock into position against parts under the machine cover. Unfortunately, my usual sources for sewing machine parts don't have parts for the bobbin winder. Thus you may have problems finding the parts even from a sewing machine repair technician. (I recommend seeing a technician to repair these electronic machines unless you are trained to handle electrical systems.) If the problem isn't the winding mechanism, then it's the control board or wiring that is probably at fault.

I hope this helps.

There is a small black plastic finger that engages the needle bar and if it gets stuck with old or sticky oil it will require some patience and dexterity to spray with oil degreaser and flexing that lever until the old oil desolves and that finger can move once again forward and back This can be accomplished through the takeup lever slot in the front of the machine The only other way is to have a technician remove the entire needle bar/takeup lever assembly and clean and oil it properly

There is a lever for positioning the needle bar. When you move the lever to the left middle or right , the needle bar too should follow the same. Try to do that. If it doesn't follow the lever and stays at one end, that means the machine needs to be oiled. Not like most sewing machines Supernova swings the bottom rod too to left and right when Zig Zag is engaged. I recommend to spray some WD 40 first, to inside of top and bottom side of the machine , and later to apply machine oil to every moving joints.

check in the manual and see where the feed dog lever is a check to see if it's in the up position for sewing or in the down position for darning, if it's in the up position, then the machine needs to be checked to see if there is something wrong with the feeddogs or the feed dog lever..

the presser foot or what ever foot your sewing with does not feed the
fabric,, the feed dogs in the needle plate are what moves the fabric
to be sewed, the feet only hold the fabric against feed dog so the
machine can use the needle to sew the fabric.
if the fabric is not moving then the feed dogs have to be checked
can you see the feed dogs in the needle plate area are the up or
down?
do you have a manual for the machine?
a manual help to know where the feed dog lever is, I'm sending
you a link for a manual for the machine, so you can look for the feed
dog lever, if the feed dogs are up then there is something wrong
with the feed dogs & they need to be checked.
but if the feed dogs are down then look in the manual & see where
the feed dog lever is & put it in the up position & see if that brings
the feed dogs up to the sewing position, if the feed dogs do not
come up then the feed dogs need to be checked.

Thank You for visiting fixya.com but you have not stated the problem you want to be solved. Please how can we help you?

Hi, I have found the most dependable thing to do is: Before removing the fabric from the machine, snip the thread between the fingers of the looper as it approaches the needle. If the loop is broken, the chain stitch will not pull out. If you cut the loop as it approaches the needle, you will get a bit longer tail so the needle doesn't come unthreaded on the next run. If you find you need a bit longer thread tail, you can pull a bit on that loop before cutting. As long as the needle has passed through the loop on the previous stitch. here i writing a site for you ,here you can get the manual.and easly fix the problem.

Remove the screw holding the regular presser foot and the presser foot holder and set aside.

Place the take-up lever in the highest position.

Hold the even feed foot with your right hand with your thumb holding the lever of the foot in its highest position. Place the even feed foot on the presser bar and make sure that the lever of the foot rests upon the needle bar thumbscrew. While holding it in place, fasten the foot to the presser bar with the screw.

As the needle bar goes up and down, the lever on the even feed foot should rest on the needle bar needle serew and go up and down as well.

From the Simplicity Sew Precious Model SWSP2 manual:

Inserting a new bobbin:

1. Place wound bobbin into the bobbin case.
2. Pull about 6 inches of thread out from the bobbin.

NOTE: Be sure that the bobbin rotates COUNTER-CLOCKWISE when thread is pulled.

1. Pass the thread from the bobbin, under the bobbin case spring, and toward the back of the machine.
2. Slide bobbin cover back into position.

Upper threading:

1. Turn the handwheel toward you to raise the take-up lever to its highest position.
2. Lower the presser foot.
3. Place a spool of thread and spool cap on the spool pin.
4. Place the thread into the first thread guide at the top of the machine.
5. Bring the thread down the right slot of the threading path, then around the tension dial. Push the thread tension release lever and pull the thread up so the thread is secure in the thread tension dial.
6. Bring the thread up the left slot of the threading path and through the take-up lever from right to left.
7. Bring the thread back down the left slot of the threading path and into the needle eye from front to back. (Clip the thread end with sharp scissors fro easier needle threading.)

Raising the bobbin thread

1. Make sure the presser foot lever is raised.
2. Hold the end of the needle thread with your left hand. Turn the hand wheel toward you with your right hand until the needle goes down once and comes back up, stopping when the needle is at its highest position.
3. Gently pull up on the needle thread. The bobbin thread, looped around the needle thread, will be drawn up through the needle hole.
4. Push the thread tension release lever and pull about six inches of both the upper and lower threads toward the back of the machine, placing them under the presser foot.
