I've read that the Elna T34 serger is basically the same as your Omega model. If you search online, you will find places that will let you download a manual-for a price.

Sometimes, if you search for and find a corporate phone number, the company will be happy to mail you a copy.

Good luck.

The Happy Lock Serger was sold by Montgomery Wards and made for them by Riccar or the same company that made the Riccar. The Happylock UTH-J-1867 is the same as the Riccar Model RL 603. Search manualslib for the owners manual and it's available for free download. I was just looking for the same thing when I did an image search of my newly acquired ( old ) serger and found the info to cross reference the model.

That serger was made for Viking by the Brother company. Just about any sewing machine repair shop should be able to get you a cord and pedal. Call Viking at: 1-800-474-6437 to see if you can get a photo copy of the manual.

Here is another singer threading manual
Should be the same.

Singer (white company) has a really good website.
You really want to reinvest in a manual for your machine, they really are a necessity.
Good Luck

Sorry, no.....but I've been thinking of calling the company. I'll post if I find anything.

If you go on YouTube and key in Brother serger 1034d threading they show you all kinds of good stuff. How to thread it, how to use different feet and the different stitches you can make.
