Threading a consew 146RB-2A

it's possible that it could be a thread tension or timing problem, when was the last the machine was serviced

Put the thread spool on the vertical spool holder with a sponge pad underneath. Wind the thread off the spool and through the small wire thread guide next to the spool holder. Take the thread across the top of the sewing arm to the tension unit just next to the gap in the case through which the thread is normally threaded - the tension unit looks like the top of a shiny screw without the slots in it. Wind the thread in a clockwise direction around the tension unit once and pull the thread with a bit of tension until it slips into the sprung gap around the underside of the shiny part. Slip the end of the thread through one of the holes in the bobbin and, preferably, wind a few turns on, then push the bobbin onto the bobbin winder shaft at the right-hand end of the top of the machine. Turn the bobbin clockwise by hand a few more times to make sure the thread is 'locked' onto the bobbin and then just push the lever adjacent to the bobbin winder to the left. To wind the bobbin, you then press the foot controller and either stop when you've got enough thread on the bobbin or let it stop automatically when full. Make sure you dont go so fast that the spool rattles-around on the spool holder otherwise this could spoil the way the bobbin gets filled.

It is usually a little tiny screw on what holds the bobbin in and where the thread passes through the bobbin. (The holder...not the metal or plastic bobbin spool of thread...it's sometimes called a shuttle to avoid confussion.) When you tighten or loosen the screw on the bobbin holder it puts more or less pressure on that metal hook the bobbin thread passes through.

You have a groove in one of your upper guides, or you have a bur on your hook assembly. Contact Robert at National Sewing Supply, 888-283-9640 if you would like more detailed information.

you shoul check your manual.

If you don't have one,
I'am not sure what this machine looks like,

On the top part of the machine, put your thread on the thread spool,(on the right) the thread should be brought over to the left side and wraped around a small button looking piece. then brought back towards the spool of thread, bring the thread through a small hole in the bobbin, pul 2-3inch out, place the bobbin on the small metal bobbin holder and push to the right,

make sure pressure foot is up. you will need to loosen the hand wheel, hold the hand wheel with the left and and with the right hand turn the center circle back to it loosend (counter clockwise)

make sure the bobbin wind evenly

1. Push in indent (illustration 1) on hand wheel disc. This will stop the needle from moving.
2. Place spool of thread on spool pin.
3. Slide spool pin holder/cap (illustration 2) firmly over rim of spool to prevent thread from tangling.

3. Slide spool pin holder/cap (illustration 2) firmly over rim of spool to prevent thread from tangling.

4. Lead thread passing it first through the lower slot of the thread guide. Next through the upper slot, leading the thread to the right and around (illustration 3).
5. Wind thread clockwise around front of bobbin winder tension disc (illustration 4).
7. Pass thread end, from inside, through small hole in rim of bobbin.
8. Holding thread end, step on speed controller to run machine until desired amount of thread is wound. (Winding stops automatically once bobbin is full.)
9. Cut thread; push bobbin to the left and remove it from bobbin winder pin.
10. Trim thread end from top of bobbin.
11. Press the bobbin winding indent on hand wheel to its original position. If necessary, turn hand wheel to engage needle movement.

If the thread is looping on the top, then the problem is with the bobbin,, If the thread loops on the bottom, the problem lies in the threading.

The machine is relatively simple to thread. This is what I do and I've had no threading problems. 1. Put thread spool on the spool pin and put spool guard over spool pin to hold spool onto pin. 2. Take thread and put it under the bent tab by the circle tensioner. bring the thread around the right side of the circle tensioner and bring around the front of the circle tensioner thing back to the top hook on the far left side of the machine. 3. Take the thread around the backside of the top hook think until it threads through the flat piece on the left side of it. 4. Bring the thread down through the first (right side) channel and under the plastic piece to the second (left side) channel. 5. Bring the thread up the second channel and around the moving thread holder and past it's flat metal piece to hold it. 6. Tuck the thread around the small wire thread holder below the needle screw. This may take a few passes to catch it. 7. Thread the needle from the front and run the thread between the teeth of the presser foot. 8. Put a bobbin in the bobbin case so that the thread pulls off the bobbin from the left side of the bobbin if you look at it from above. 9. There is a small channel in the bobbin case that is covered by the bobbin tension flat piece. Pull the bobbin thread through this channel and into the empty space where the needle thread will catch. 10. Place the bobbin case into the machine with the little set bobbin arm pointed to the sky so that it fits into the machine without wiggling to the right or the left. 11. Turn the, uhhh brain fart, the hand wheel until the needle comes back up with the bobbin thread hooked over the needle thread. Take a narrow thing, like scissors or a seam ripper and pull both threads until the bobbin thread comes up. Now your machine is threaded. Use these directions with the pictures in the book to get this machine threaded.
