Juki MO6714 Mechanical Sewing Machine - Answered Questions & Fixed issues

Hello Keith, From the little information you stated, I can only take a stab at what might be wrong with your machine. I suggest you make sure the take up spring is working freely and properly.

completely un-thread the machine and rethread it in this order. Upper Looper, Lower looper, right needle Left needle. It has to be in that order ALWAYS. If you break a thread... un thread and start the threading process again. If rethreading doesn't work... change the needle that is skipping. Good luck

hi there,
which blade you change? upper or lower one?
for lower one just make the top surface for blade aqual with throat plat.
for upper lower turn handwheel to make blade at lowest position in that time the upper lower must be lower than lower blade by arround 2.5mm and keep in your main the two blade also must be very close no space between it.
best regards

Hi, yes I believe that will work, however you may need to re-adjust several time to get it perfect, my wife ( who's owned a couple industrial machines agrees ) use some scrap material to make adjustments and if possible ( with machine unplugged of course ) turn by hand to make sure it is not too far and could jam. I hope this was useful, please write back to let me know-even if not so we may try to help some more. Thanks for asking FixYa, and good luck-Prodzilla

Try turning the upper tension higher, if its set to 4 then try 6 or so. Make sure its threaded correctly as well.

It is likely the wiring has rubbed through and shorted, or it is the motor. Test and diagnose. https://www.google.com/search?q=Juki+5550-6+sewing+machine%2C+popping+sound%2C+burning+smell ..

You should make sure it is grounded. Also, is it getting oil from the pan? Blown fuses usually mean there is an overload in the motor. Check that the belt is not too tight.

I am not familiar with this particular machine, but I found references to the thread cutter. Did you try turning it off? Could the cotton thread be rotten, have you tried sewing with button thread? Thread Trimming Function correlates with the scissors icon on the face of the machine. The G210 in unique in the fact that it has this function, which will automatically trim the thread for you, leaving virtually no mess! This one is a life saver as it relives you from having to spend time cutting and cleaning loose threads!

There is a problem with the motor. Check your connections of wiring and such to make sure they are secure. The problem might be the brushes or might be the circuit board to the motor. Look for signs of damage or wear on that main circuit board. If found, replace the board. If the problem is not then resolved, you might contact Juki customer support. This is not an inexpensive machine. https://jukiamericas.com/pages/support https://www.citysewingmachine.com/products/juki-ddl-5550n-7-lockstitch-machine-setup-on-table-servo-motor-stand.html https://www.manualslib.com/manual/940610/Juki-Ddl-5550n-7.html

If your JUKI HZL-DX7 sewing machine's automatic thread cutter is leaving behind a short piece of thread in the mechanism after each cut, there might be a few potential causes for this issue. Here are some steps you can take to troubleshoot and address the problem:

1. Thread Tension: Check the tension settings for both the upper and lower threads. Improper tension can cause thread to be left behind in the thread cutter mechanism. Make sure the tension is balanced and appropriate for the type of fabric you're sewing.
2. Thread Quality: Poor-quality or thick threads can sometimes get caught in the thread cutter mechanism. Ensure you're using good-quality threads that are suitable for your sewing project.
3. Thread Path and Thread Guides: Make sure the upper and lower threads are properly threaded through the machine's threading path and guides. Improper threading can lead to thread buildup in the cutter area.
4. Thread Cutter Mechanism Cleaning: The thread cutter mechanism might have accumulated lint, debris, or bits of thread over time. Gently clean the thread cutter area with a small brush, compressed air, or a vacuum cleaner to remove any buildup.
5. Blade Inspection: Check the blade of the thread cutter for any nicks, dullness, or damage. A damaged blade might not cut the thread cleanly, leaving behind remnants.
6. Thread Cutter Mechanism Lubrication: Some sewing machines have small moving parts in the thread cutter area that benefit from occasional lubrication. Consult your sewing machine's manual to see if lubrication is recommended and use a sewing machine-safe lubricant if needed.
7. Machine Maintenance: Regular maintenance of your sewing machine, including cleaning and oiling as recommended in the manual, can help prevent issues with the thread cutter mechanism.
8. Consult the Manual: Refer to your JUKI HZL-DX7 sewing machine's manual for specific instructions on troubleshooting and maintaining the automatic thread cutter.
9. Professional Service: If the issue persists after trying these steps, it might be best to seek the assistance of a professional sewing machine technician. They can diagnose and repair any mechanical issues with the thread cutter mechanism.

Remember that working with sewing machines involves mechanical parts and electrical components, so it's important to follow safety guidelines and, if needed, seek professional assistance to avoid causing further damage or harm.

Standard procedure for a jammed machine is to force it in the normal direction of travel.. I can't think or any logical reason for the machine to lock the handwheel when switched off and a mechanical jam would be the reason for the motor overload. https://www.manualslib.com/manual/1605037/Juki-Ddl-9000c-S-Series.html?page=71&term=turn+handwheel&selected=1#manual ..
