A Good cleaning and oiling might help. Check if the needle is in backwards. That will sometimes give you a problem with the bobbin thread.

thank you for your quick response! I have never had a machine that I could oil myself, so this will be an new experience for me!

Do you have the bobbin winder disengaged? It is the little silver knob on the right hand side of the machine. Down is engaged. I sew everyday on a 600. You can take the top and bottom off and put lube on the metal gears and oil everything else that moves. Take the bobbin shuttle out and and the throat plate off. Dust really good there and put a few drops of oil where the bobbin shuttle goes.
Good Luck,
Susan

thanks, Susan!

Since you sew on the same machine, does your machine have a metal button to the right of the throat plate position knob? Do you know what that is for? The manual that came with this machine says there is a bobbin push button in the bobbin area, but mine doesn't have that. Would that metal button have something to do with it?

The button you are describing is the button I was talking about in my earlier post and it is the bobbin wind button. Down to wind and up to sew.
The later model machines have it on the inside. I learned to sew on a 70's model T&S.

thank you, Susan. You really helped!

I just got a Singer Touch and Sew 600 and I need to find a users manual and bobbin so I can see if it works. Know where I might get a manual and what class the bobbin is? Thanks Judy

You can get the manual and bobbins here. It take special touch 'n sew bobbins that are relatively flat and the top and bottom unscrew to remove the thread.

Here is a link that might be useful: Touch 'n sew parts

I'm just wondering if anyone has trouble with the foot pedal on the touch & sew. Mine is more like a small square vs the whole foot pedal pushing down. It pushes easily but the machine runs slow or super fast. I can't seem to get it to run at a reasonable sewing speed. I'd appreciate any help. Thanks!

My T&S 600 bobbins (plastic) seem to be getting nicks around the outside edges. Also I'm not able to successfully fill the reel beyond the second or 10 yd mark before it fills unevenly. Are metal bobbins available for purchase? I have just finished cleaning/oiling/maintenance in the bobbin area and still getting nicks.

I would love to work out the bugs before I give it up as a lost cause.

I'm a 71 year old retiree. I have suffered a stroke and think working a sewing machine is good therapy. I just found this Auto reel 600(singer touch n sew) at a thrift store. It seems to work well, but I will welcome any hints or tips.
