Bobbin won't thread

I'm having difficulty with my Shark Euro-Pro 373. The bobbin won't thread with the top thread, and the top thread keeps collecting under the bottom of the material. I haven't tried much regarding fixing it since I can't find my manual. I'm not sure if pushing down on the peddle all the way makes a difference or not. Thanks!

Re: Bobbin won't thread

Sounds like the bottom tension is to slack.
Look at the side of your bobbin case, when you thread the bobbin thread part of the route it runs is under a flat leaf spring. There is usually 2 very small scews on this leaf spring one screw holds the spring onto the casing and will be tight. The other is the tension adjuster screw, turn this screw clockwise half a turn at a time. After each half turn pull the bobbin thread until slight resistance is felt. Then try sewing if bunching/tangles still occur more tension is required, this is trial and error until the tension is corrert.
If you want a new manual try this website if your machine is not listed email them and they will try to help.

I have a euro pro shark sewing machine. I just changed the thread for another project and cannot get the needle to pick up the bobbin thread. Any ideas?

Try installing a brand new needle. Bent/damaged needles will sometimes not pick up the bobbin thread.

Make sure the machine is threaded correctly. Check the bobbin--ie, it is turning the correct direction in the bobbin case and is threaded properly through the bobbin tension.

You might also try pulling the bobbin thread up to the top before beginning to stitch.

My Shark 7133 slowed down while sewing and stopped. The handwheel won't turn at all. I cleaned the bobbin area but it still won't work. The light switches on and the machine motor reves up but...

Slacken the stop motion as if to wind a bobbin and press on the foot control, if the motor runs really fast then you have either thread stuck in the bobbin case area or you may need to oil the machine

I can't get the bottom thread to come up with the needle on my euro-pro shark intelli-sew

try this
make sure there is a 3-5 inch tail on bobbin thread
make sure there is a 3-5 inch tail on top thread, then hold the top thread tail with your fingers (away from the needle) & with your other hand turn the hand wheel manually on the right side of the sewing machine,, slowly letting down the needle down into the bobbin area & see if the bobbin thread will pick up this way

Zigzag stitch pulling tight, looks wrong

Try adusting the bobbin thread instead of the top. Always make sure to insert the bobbin so the thread is pulling in a clock wise direction. Both threads top and bobbin should have about the same resitance when pulled.

How to oil euro-pro 373?

Have you tried flipping the bobbin in it's case, so that the thread comes off the top of the bobbin instead of the bottom. Some machines are sensitive to one direction of the bobbin thread.
