My Empisal 760c Overlocker Not Sewing?

Yes there is another prolem it is in your bobbin area that is causing you the issue. You need to remove the bobbin and check this area for any thread or fur that might have gotten in there. There are 2 latches on the canister of the area that need to be remove or moved over so you can remove the 2 metal pieces so you can clean out this area.

Check under the feed dog to make sure there are no thread there and clean them out.

You have good instructions for cleaning your bobbin but I think you may be causing the problem with the material you are sewing as this type of material has lint and 'pieces' coming off all the time.
I would suggest you a stabilizer fabric over your material so maybe all that gunk will not stop up your machine.

If you're still having trouble or cannot understand exactly what to do I would suggest you visit a Michael's or JOANN store and see if they can recommend someone to help you.

You may have to pay a charge but it will get your machine going so you can finish your project.

Any sewing store has people that can help with this as almost all overlocker machines are very similar except maybe the threading as this is one of the most intricate things about each machine.

Sears Service Center is also a good place to ask for help and they will sometimes do the repair (one like this) while you wait - much cheaper bill.

Please think about the stabilizer as it really helps when working with this type of material.

This is a classic cause of threads, fabric, string build up in your housing and bobbin area. Over time this gets in and halts your machine.

This will require cleaning out all debris inside housing bobbin area.
