    I have lost the manuel for my babylock protege and need the threading instructions. the lower threader keeps coming unthreaded. I have followed all the blue lines for threading and had the serger professionally cleaned.

I was in a similar position (but had the manual). The manual isn't as complete as I'd like. Anyway, what finally got mine working were the following:
1. turn all tensions to zero before putting thread through them
2. thread the upper looper, then lower looper, then needles.
3. when threading the lower looper (mine kept pulling out), after passing the thread through the looper eye, it needs to go pretty much straight up, not wrapping around anything else - other thread, for example. Mine was at one point trying to wrap itself around a post.
4.when everything is all threaded up, make sure all threads are under the foot *and* pulled to the left (even though the manual says pull to the back). Then chain off without fabric, turning the handwheel by hand to make sure loops are forming. If so, adjust tensions to where you think they should be (mine are currently all between 2 and 5), and add fabric. Then tweak as needed.

For me, this was a lot of trial & error, hair-pulling, and getting tips 1, 2, and 4. I figured out #3 on my own, with much swearing along the way. Good luck!

Baby lock serger will not feed, fabric want come out from under presser foot.

what is the stitch length set to? should be 2.5 or thereabouts for normal serging.
Is the pressure foot pressure turned up too high perhaps?
The reasons I could think of for it not feeding through would be:
- the feed dogs under the pressure foot are out of position/not moving
- that the differential feed is turned up so its pushing the fabric back to the front of the machine
- stitch length is set very low so hardly moving the fabric at all
- or youv'e got a thread tangle happening around the foot/blade area.

When was the Elna Pro 4DE manufactured?

I'm thinking early 90's maybe but can't find a specific release date for this model online.

I do know that the first Elna Locks were released in UK in April 1987 and first models were L-1 (3 thread), L-4 (4 thread), L-5 (combo chain and 3 thread) because I was trained to demo these models.

Differential feed was a feature that soon followed in the home lock market across all brands.

Maybe try Yahoo group Sergers and ask there, there could be some members who have this model.

How to use the differential adjustment knob on the Juki MO-644D. Not seeing instruction in the manual

Found the manual here on features page
Differntial feeding is covered on page 25, and the diagram showing location of the differential feed knob and stitch length knobs inside the cloth plate is on page 2.

So swing open the left cover (cloth plate) to access these controls.

Differential feed means you change the feeding speed of the two feed dogs so the front one feeds at a different speed to the back one. Effectively, this either streches the fabric as you seam, or pushes the fabric together as you seam. So if you want to do a rolled hem "lettuce" edge you are stretching the fabric with the differential feed to achieve this, turn the numbers up. If you are sewing a loose knit and it is "waving" then turn the diff feed down to 0.7 or so to squeeze the fabric back together.

That's basically it! Like anything on an overlocker, test sew, adjust, test sew, adjust until you are getting the right effect.

How do I operate the differential feed? I bought

The differential feed is usually on the right side, you will see a some numbers. Their should be one that sticks out (might be red, The letter "N", "0", or a line) This is the normal setting. A larger number is going to gather the fabric and a smaller (.99 and below) is going to stretch.

Hope that helps :)

My white speedylock 1600 is being difficult.. The top threads lay and look perfect.. but the bottom threads are loose.. What can I do about this?

This machine has differential feed (top tension is different from bottom and fabric feed rate can be different from bottom). turn the dials for tension and feed rates to adjust. Adjust bottom tension to tighten bottom threads and possibly speed up bottom feed rate. Tough to say without more info.

Good luck and please rate me.

From White Sewing web site.

"Are wavy fabrics making you seasick? Do puckers leave a sour taste in your mouth? Then you need differential feed. It eliminates distortion and wavy seams when serging knits, plus it prevents puckers and pulled seams on lightweight fabrics. Turn the dial again for instant gathers.

First, try the differential feed. I think that you set it so that the setting is less than 1 to get it to feed in faster than out. If it isn't working, try a higher number.

If you can't get enough this way, the old fashioned way would be to reduce the presser foot pressure slightly and put your left index finger behind the foot, resting on the fabric to impede its progress through the machine.

I think that the differential feed should suffice.
