I don't see why not, your manual is fantastic, if you go to page 136 and boy do you have a great diagram of your whole shuttle area, I am envious, mine is nowhere as good. If, you download your manual at www.brother-usa.com under support, you can really enlarge that diagram and see exactly what you are doing. You can also call Brother at 1-877-276-8437 if you are worried about voiding your warranty.Good luck

Industrial sewing machine has jammed, the wheel will not turn


Hello Christine, I think you do have a thread stuck between the rotary hook and the bobbin case carrier. Remove the bobbin case and bobbin. You will need to remove two small slotted head screws and remove the half circle locking ring that holds the bobbin case carrier in place. Try to wiggle the bobbin case carrier one way and than the other until it comes out of the rotary hook assembly. Don't pry too hard or you might damage the carrier and/or rotary hook assembly. Once removed, I think you will find the thread that is causing the lock up situation . Before reassembling, place a drop of oil on the bearing surfaces between the carrier and rotary hook assembly and also between the locking ring and the carrier.

Singer sewing machine bobbin case keeps moving causing the needle to break.


Is this a front loading bobbin or top? If it is a vertical front loader with the little metal bobbin case, the metal case has to be lined up and snapped firmly into place. You should hear it snap and lock into place.

If it\'s a horizontal or top loading bobbin, and the plastic bobbin "tray" is rotating, then it may not have been nested in properly, before replacing the plate, or may be "jagged" somewhere... If there is a burr on the casing, or as in the case of one machine I worked on, still have a piece of needle stuck in it, the thread will snag on it before it finishes rotating and the rotating motion catches half way and will jerk the case right around and the next stitch will break the new needle.. Those plastic bobbin "trays" are usually easy to find and replace if they have become too burred to use. I have also sanded them smooth again as well though.

To test it, unplug the machine, thread your machine on top, but leave off your bobbin lid and leave out your bobbin, hold the top thread (like when you are about to crank to pull up a bobbin loop) and hand crank toward you, or counter-clockwise one complete rotation. Watch to see if the top thread is caught by the rotation hook and slips all the way around and back over the top of the bobbin tray, or if it snags on it somewhere.... Good luck!

Singer 1425 is bound up. The knob on the right side of the machine will not turn. Do you have a suggestion?


This can be a bit tricky, these are the steps I start with to free up a bound machine
1. lift pressere foot up
2. remove needle plate
3. remove bobbin, case, hook on side load bobbins
4. Try to turn hand wheel
5. If still stuck, remove top cover of machine and use a high quality oil and lube all metal to metal moving parts.
6. remove bottom of machine and oil.
7 look for something broken like gears or machine out of time

Wait a day or two for oil to get in a do it job, if still stuck contact a repair shop.

Help, my mom is out of town.. I sew two or three stitches and the machine stops. It sounds like it is stuck. I have taken out the bobbin and it doesn't look like anything is stuck?


Get out the manual and start with maintenance so you can be sure the bobbin area is clean.

Now start at the beginning of the manual.

Read and apply as you wind the bobbin and place it into the bobbin case.

Thread the machine - again - read and apply.

Pictures and graphics are very helpful but don't always highlight some of the important steps.

CAN"T FIND THE MANUAL -

Remove the bobbin-case and clean away any thread the may have tangled there.


Make sure the thread is tight and even on the bobbin,

If this is a vertial bobbin/metal bobbin case, the thread winds from the bobbin clockwise and then through the opening on the side of the bobbin case and under the guide just above the opening.

Lift the needle to it's highest position and then lift the lever on the bobbin-case and hold it open as you insert the bobbin-case into the shuttle.

If this is a drop-in, horizontal bobbin, the graphic on the plastic lid covering the bobbin will indicate which way the thread feeds from the bobbin and through the guides.

Replace the needle, with the flat side of the shank facing the back of the machine.

Lift the presser foot and re-thread the machine. IMPORTANT - always have the presser foot up when threading.

Hold onto the thread end, lower and raise the needle to pull up the bobbin thread, Take both thread ends under the presser foot and to the back of the machine.

Place a double layer of fabric under the presser foot. Hold onto the thread ends and lower the needle into the fabric for the first stitch.

Press on the power pedal.

Machine is very loud and jumpy


Hi,
Usually this problem occurs on machines with a front load bobbin case. If so, remove the bobbin case, the shuttle hook cover (two levers to the sides of the bobbin case area cover and shuttle hook (part the bobbin case goes on and it is ½ mooned shaped). Then clean and oil (with Q-tips and sewing machine oil NOT 3 n1 oil) the round outer area where the hook rides. No lint at all and squeaky clean. Then 3 drops of sewing machine oil in rounded groove where the shuttle hook rides. Then replace the pieces:
Replace hook:
Identify the the hook driver (still in machine), it is 1/2 moon shape. The hook is also 1/2 moon shape. If you lay the machine on its back,( it's easier). Set the hook 1/2 into the other 1/2 of the hook driver to make a circle. Then put the hook cover on (machine still on its back) with the tabs for the twist locks pointed to you. Needle gaurd on hook cover to the top of the machine. Snap the twist locks in place, replace the bobbin case and viola!

Embroidery hoop gets stuck to the plate and needle breaks


This has happened to me as well. What I usually do is:-
* remove bobbin case and clean out any lint, also under the needle plate, then replace needle plate , bobbin case and the little front cover. replace the bobbin , checking that you have the thread going the correct way.
* replace the needle with a new one of the correct size for the weight of your fabric and the weight of your thread
*remove and rethread the top thread
* check that the stabilizer is of sufficient weight for the density of the design. (You may need to float an extra piece of stabilizer underneath the hoop)
* check also that it is bobbin-fill in your bobbin (it is easy to get it mixed up)
* when stitching out lace, sometimes it helps to hoop the solvy double.

Send this machine back where it came from! machine. You have described a timing problem which you can not and should not need to do.
Change the needle first and test it to be sure the needle still hits on the hook. If it does,follow the above instructions. If it no longer hits then it's possible it is not as serious as I first thought.I'm not sure if the bobbin keeps coming out or the bobbin case(the plastic part the bobbin sits in) comes out.If it is just the bobbin, insert the bobbin in the case and pull on the thread. The bobbin should turn COUNTERCLOCKWISE. If it turns the other way, turn it upside down and try it again.
If it is the bobbincase,then Remove the needle plate and take the bobbin case completely out. On this machine there is a small lever which holds the bobbin case in position. Looking down on the bobbin case the lever is located at about 11 o'clock and has a small slot in it. It is also probably spring loaded which means it is not easy to turn without a small screwdriver. Insert the screwdriver in the slot and turn it to the left. Lift out the bobbin case and Carefully examine it for any nicks, scratches or rough spots. If you find any, they will need to be removed with an emery stick and or a sharpening stone. Buff with a very fine steel wool for total smoothness.
To replace the bobbin case use the screwdriver to open and hold the lever open while you insert the case back in. The straight part of the case will be on the right and you need to place the case so that the circular part rides on the slight grove in the hook.(The metal thing it sits on). Once you have it in place you can release the lever you've been holding open . It should fit over the edge of the bobbin case and not allow it to come out. Rethread the machine and turn it by hand a few times to see that it is working properly. Good luck!!!

Bobbin Case


I'm having a similar problem today. I took out the bobbin case and when I went to put it back in, the whole system locks up. I've tired cleaning, changing needle taking the metal plate and piece that holds bobbin case out and put it all back in after cleaning. Nothing. My symptom is I can't get a complete stitch, the needle goes down, the whole deal acts like it will work and as soon as the arm of the bobbin case gets to 8 o' clock on the gears, It jams and won't hardly move. I cannot pull the bobbin case out easily after this. Perhaps there is someone out there that can help us!
