SOURCE: Filling the bobbin with my Juki DDL-5550-6

It's actually designed that way on purpose so you can wind a bobbin while sewing. If you lift the presser foot, at least it'll make less noise in the process.

SOURCE: Juki Sewing machine DDL-555. After 4-5 hours use feed not moving

Sounds like as the machine builds up friction from extended use, some vital part is lacking lubrication and is seizing up. A good service person will remove ALL of the covers and thoroughly air clean and oil every moving part. Sometimes these dry points are hard to find and patience is required.

You can get a sewing machine oiler with a long applicator and put a drop of oil on anything that moves, but over oiling can be messy.

SOURCE: I bought a second hand Juki industrial machine ,

upper tension sets the lower thread tension (upper thread is what you see on the underside of the fabric). Bobbin tension is for the thread you see on the top of the fabric

SOURCE: thread and bobben pattern for juki ddl 5550

Your bobbin case may be too tight. Try loosing it by turning the small screw a little turn to the left. If thats not it, you could also have a bend or snag in the bobbin case that is snapping the thread. If this is the case you will need to replace it.

Juki DDL-227 won't spin

:) welcome to the world of industrial machines. The good news is they are typically simple machines.

It is a good habit to take a few minutes to clean and oil your machine before you start sewing. Look for the oil points and give it one drop of quality sewing machine oil in each port.

Now let's try to determine why the hand wheel isn't turning. Loosen and remove the belt from the large reducer wheel under the table to the sewing machine. Try to turn the hand wheel. If it does turn.... Good! If it doesn't turn... we know the problem is in the the machine head and not the wheels below.

Make sure there is no bobbin thread or upper thread. Try to turn the hand wheel again. Anything?

Look carefully at the machine... is the take up lever bent? (personally had this happen with friends helped me move a big machine like this.)

Keep working this way... inspecting the machine until you find the problem. Good luck

My Elnasuper makes a whirling noise but none of the moving parts will move. Light works and I tried the foot pedal on another machine and it is fine. Any ideas?

This is a machine with the motor and belts hidden inside right? Your belt is broke. While you can replace yourself... it's likely that it threw the machine out of time... and it is very easy to through the machine out yourself when you replace the belt yourself (ha! ask me know I know!)

If everything works when you use the hand wheel... take it in and have the belt replaced.

Motor runs but belts not moving, How do I fix this?

First, give it a good cleaning and oiling. It may need some grease on the gears. If the belt is still not moving, it could be too loose...stretched out. In that case you would need to replace it. This seems pretty complicated. If the cleaning and oiling don't work, take it in for service. You can download your manual here:

My husqvarna 500 computer won't start. It ran for a while after I got it tuned up and then stopped running again. The lights come on but the needle doesn't move. Turned it off and on again as...

Did you leave the foot control with the machine when it was service? I normally will not keep the foot control when I check a machine in for service as long as the owner feels it works okay. The cord must be firmly seated in the back of the foot control. Some people have had a loose cord for 10 years and never realized that it just isn't fully inserted. Also, make sure that it fits fully into the machine. Sometimes they feel like they go in but a second try lets them drop in fully and work normally.Beyond that, you should probably have the person who tuned it up for you have another look at it. Is it still within it's warranty period from the tune up. Most dealers won't mind taking a look and advising you on what is going on.

The belt is not moving when i pres the pedlle

it sounds like your machine may be seizing up. it needs a service. oil all moving parts with good sewing machine oil (not 3-in-1 oil) and work the oil n b turning handwheel by hand for a while.

if this does not free-up machine have it serviced by a tech.
