I have a singer ultralock 14u34. The lower looper will not stay threaded when I try to sew, just works for an inch then nothing is catghing and the looper is no longer threaded.

The 14U34 does not need to be oiled by the user.

Most Singer manuals are available here: http://www.singerco.com/support/instruction-manuals . The direct link to the manual for the Ultralock 14U34 is: http://www.singerco.com/uploads/download/664_14u34b,234b.pdf .

I hope this helps.

Hello Monica Trail

Yes, the 14U34 will do a beautiful rolled hem! Instructions begin on page 26 of the manual which can be downloaded at http://www.singerco.com/uploads/download/c3e39bce98fa1e2c9c9b9f603c3365a0d5fd8dc2.pdf

Enjoy rolling!

You can find a threading diagram at this site:

or download the full manual at this site:

Start with the threading sequence. Upper looper, lower looper, left needle, right needle. Your upper & lower loopers must be threaded before your needles or it won't make the stitch. If it still doesn't work, it's out of time and will need to be taken in to a shop.

"Coming undone" What do you mean? Is it breaking while sewing? Is it too short and is slipping back through the needle?

If it's breaking, try changing the needle. If i's slipping back... give it some length when you thread.... and at the end of a seam Run it out... 10 inches before you cut it off close to the fabric. That little bit of thread waste will make you feel much better about your serger.

I had read where someone said their lower looper tension dial had pulled apart. Sure enough, mine had too. We snapped it back together and Voila problem solved!

When servicing these machines I have found that the cover over the tensioners needs to be removed so you can see if there is more adjusting possible. If its a newer serger you would hold the knob somewhere in the middle (4-5) and adjust the knurled part that goes through it. Many times I have had to rebuild these tensioners as they get dirty and need cleaning and adjusting. It may take many tries until you have it adjusting correctly. But it needs to be done.
