Needle not dropping to fabric. Wheel will not turn to get it there.

Try 20% pressure on treadle that should release the pressure enough to turn wheel

To do the basic rectangular button hole, make sure that you have plenty of thread in your bobbin. Put on the button hole foot. Mark your fabric before starting for the button hole locations. Testing the button hole on an extra piece of your fabric is useful for checking the tension balance. Next place your fabric under the presser foot and center the right side of the button hole position with the red alignment marks on the foot. Set the stitch to button hole stitch 1. Turn the hand wheel to bring the needle into the fabric at the point in the center of the needle opening of the presser foot. Stitch to the end of the planned button hole. Use the hand wheel to bring the needle out of the fabric and turn the stitch selector to the button hole stitch 2. Make at least 4 stitches and stop with the needle to the left side of the bottom of the button hole. Raise the needle and set the stitch selector to button hole stitch 3. Stitch back to the top of the button hole. Raise the needle and set the stitch selector to button hole stitch 4. Stitch at least 4 stitches. Raise the needle and the presser foot and remove the fabric. You can move to the next button hole or carefully cut the button hole opening.

The manual gives the directions for the 4-step button hole on page 28-29 (pages 30-31 of the PDF). Many Singer manuals are available here: https://www.singer.com/support . Singer has two manuals for the 6212. (One manual covers two machines; the other covers 7.) The manual to the first manual is currently here: https://res.cloudinary.com/singer-sewing/image/upload/fl_attachment/Singer-Website-Library/outdated_product/SINGER_6202_and_6212_Sewing_Machines.pdf .

I hope this helps.

The needle should only go up/down. Sewing forward or reverse involves the feed dogs grabbing and moving the fabric. On most sewing machines, you should never turn the hand wheel backwards. This can change the timing and damage the machine. Instead, try holding the Reverse lever or button then turn the hand wheel forward.

Since the sewing machine jammed with the needle bar at its lowest point, open the bobbin cover. If you see a loop of thread, try and slide that loop until it clears. If there are several loops around the bobbin/bobbin case, you might try carefully cutting the thread. If the fabric of your sewing project has been stuffed into the needle opening on the plate, try carefully clipping threads to loosen the jam.

If that doesn't work, then double-check that the bobbin winding mechanism isn't engaged. If the unit is still stuck, you might have damage to the various linkages/bearings between the hand wheel and needle bar. The problem may require taking the machine in for service.

I hope these ideas help. Please add a comment with the make and model of the sewing machine for further assistance.

(When you do get the needle bar to go up, you may want to change your needle. Also change the needle plate to the straight stitch plate if you are doing a straight stitch with a lightweight fabric.)

There is a button or lever that controls the feed dog position. It might be dropped below the needle plate for darning. Locate this button and see if the feed dog are above the needle plate when you move the balance wheel.

Look at the feed dogs to see if they are rising above the needle plate at least 1 mm. If not rising lint may have felted between the feed dogs and the needle plate. It could also be the feed dogs have been lowered, or the height has slipped. If the feed dogs are above the needle plate turn the hand wheel and see if they are moving from the front of the machine to the back. If not it is a length adjustment. If this is normal the pressure on the fabric may be too low. Another problem may be the timing of the feed dogs. The feed dogs should rise above the needle plate when the needle leaves the fabric and descend when the needle comes down into the fabric. This requires an expert to fix.

Sew to the end of the fabric, slowing right down to within a stitch or two of the end, manually turn wheel to complete last two stitches, stop, raise needle, raise presser foot, turn fabric so the back edge of the fabric is just under the needle, drop needle, drop presser foot and resume.

I will stop at the overlap and slowly go through the fabric by turning the wheel manually and carefully handling the fabric with both hands, for example, when hemming bottoms of pants where the seams are

Dropped stitches troubleshooting:
1>change to a new proper needle (proper needle means quilting needles for free motion, stretch needle for knits, leather needle for leather, microtex needle for micro fabrics.....etc.) of proper size. Most sewers never need a needle smaller then an 80/12 when sewing. Smaller needles bend more easily causing more problems.
2>If a new needle doesn’t fix the problem, remove parts from bobbin case area (as best as easily allowable) and clean out all the lint thoroughly, and oil with 2-3 drops of oil where friction occurs (turn hand wheel and look for rubbing)
3>If still skipping, try a different spool of thread (Yes, thread can caused skipped stitches, not common but I see it).
4>If you haven’t solved it yet, sounds like you could need to make a lower level adjustment like hook timing.
Hook Timing:
To time the machine, you want the tip of the hook to pass just over the top of the eye of the needle when the needle is in the left most or right most position depending on which side the eye of the needle will be higher

hi! there wind thread on bobbins winder 4 times by your hand rotate clockwise,insert in shaft bobiins winder on top of your machine near hand wheel push latch to engage loop thread on disc winder tension start your machine on pedal foot automatically winder disengage if already filled up of thead pull this winder and insert to bobbins casing insert thread to slot and pull out winder should rotate clockwise as shown.insert on shuttle hook casing and close cover needle plate.next thread your upper

threading tension as shown on red threading from spool pull threading and loop to dial tension threading and insert thread to lever needle and to needle hole tip. pull tread under the needle foot and feeder tooth.rotate hand wheel counter clockwise to hook up thread bobbibs and appear at top of needle plate,teo thread shoul appear,set dial tension to # 3 and stich to # 8 range to # 12 depend on fabric and layer of fabrics and set on straight stich sewing,let needle on upper position insert fabric for trial sewiing.put down foot needle lever. manually by hand rotate for assurance needle is free to sew if obtruction on loop bobbins thread occurs adjust all tension gradually then try again until free from sewing w/o problem star sewing.

First ensure that your bobbin is threaded correctly. Most drop in style bobbins the thread will feed off in a clockwise motion. Also make sure to only move the hand wheel (on the right) toward you (counter clockwise). When you begin sewing ensure that you start with the needle in the fabric and when you end that your needle is in the highest position.
