Looping on the top means there is no tension on bottom. The bobbin thread generally rotates counter clockwise. The thread must get under the tension spring. The spring must be adjusted equal to the top tension. This you will have to play with to tighten or loosen as needed. When you sew in a zigzag you might want to loosen the top tension slightly.

On a regular basis remove the bobbin case and clean with a qtip. On the race put one drop of sewing machine oil. Clean the bobbin case and replace. Answered on Mar 25, 2017. First, take a look at page 68 in your user's manual. If you don't have it, you can download it free at the Singer Sewing machine site.

You can (and periodically should) remove the face plate over the thread path for cleaning and oiling. There are probably threads wrapped around a part there, and in addition, you can take a flashlight and look to see if there might be threads underneath the bobbin winder preventing the machine from moving. More rarely (but possible) there may be threads wrapped around the gear underneath the bobbin basket (holds the bobbin case), so you,may need to remove the base to access that part, but it's generally not a difficult process. While you are there, it's probably time to use a little sewing machine oil and lubricate the parts, as per your user's manual.

We list a lot of our trade in sewing machines on eBay (the nice ones). This is a machine that we are going to list, but thought we’d give local customers a chance to purchase it first. The advantage to living here in the Coos Bay-North Bend area is you get to test drive the product before purchasing. See it here and save on shipping when you visit the Electric Hospital. One of the things we get a lot of requests for is a basic, easy to use, straight stitch/zigzag sewing machine.
