    The manual for this is so confusing when it comes to upper looper thread right before threading the eye. (where is show the dashed area where the thread should go.) I assumed the broken line means it should be in the back and come forward before threading the eye. I've tried both ways and it still doesn't seem to be stitching correctly. Anyone else confused with this?

When you thread the serger, your suppose to start threading the 3rd spool (left to right) first, then the 4th spool, then thread the 2nd spool which ends up in the second needle (left to right), There is a lever or bottom looper that the thread must go through before placing thread through the 2nd needle. Finally, the last spool to thread is the 1st spool (left to right). Follow the threading pattern and once you put the thread through the two loops that look like springs, turn the wheel at the right toward you until you can see like a lever with a ****, thread that **** from the back then put the thread through the machine to the right. Turn the knob to toward you again until the upper looper is showing, then you have the put your thread through the hole in that looper then through the first needle. You should now have 4 thread toward the back of your machine which you need to place under the presser foot and to the left side of the machine. There is also a VHS video that goes with the machine to help explain how to thread your serger. Also be sure that each spool of thread is in the tension of the upper colored tension wheels. If it is not, then your stitiches will be loose. Good luck and I hope this helps. I had to watch the video several times before I got it. If you don't have the video, try ebay for and perhaps you can obtain one. The video is Speedylock 1600, instructional video, USA Part #136000016, Perhaps you can contact White and see if they have one you could purchase.
Good Luck Serging!!!!

The threadguides for overlockers, or sergers, are generally colour coded these days.

Your top looper is the 2nd from right, so if you can follow the colour of the tension unit around the guides this should sort you out quickly...

..if it is the White Speedylock 1600 you have, there is a (somewhat confusing) reference guide at SewUSA here

Start threading your serger by beginning with
the upper looper.
Slip the thread in back of 1st guide directly under the
tension dial from right to left.
Slip the thread under the following four guides
Next thread the eye of the looper, and then pull the
thread to the rear of the serger, leaving
about eight inches of thread.

The tread from the lower looper is not being picked up by the upper looper how o i fix this?


Best advice would be to consult your owner's manual. The most common serger problems are caused by incorrect threading or not threading the threads in the proper order. With most sergers, the upper looper should be threaded first. The lower looper is threaded second and the lower looper thread tail should drape OVER the upper looper. Then thread the needles.

Be sure when threading that each thread is pulled snugly into the tension disks.

Adjusting tension on overlocker


overlockers and sergers are annoying in that every time you change materials and threads they must be re-tensioned.

Get a scrap piece of material. Thread your machine correctly according to the instructions in your manual. If no manual most sergers are threaded, upper looper, lower looper then needles from right to left. Make sure you thread with the presser foot UP.

You want to balance the stitches Begin by adjusting the looper dials, you want them to meet right at the cut edge. Then adjust your needles. Keep doing test seams until you have them balanced. If you are a novice... try threading with each thread point having it's own color. That will help you identify which thread is giving you fits.

Have fun.

Stitching is too loose on the Juno Janome Serger Model 3434D


sergers the most frustrating machines. Every time you change fabrics you go through a tension adjusting phase.

First make sure you have threaded the machine in the proper order. upper looper, lower looper, then needles from right to left. Always thread any machine while the presser foot lever is in the UP position.

If you ever break a thread... you MUST pull all threads and rethread using the proper order.

Ok that's out of the way. Pull all your threads and get out several pieces of the same fabric scrap. Thread each pathway with a different color. This will help you determine which thread is giving you fits. Sew a test strip. Which thread is loose? tighten/loosen that tension. Keep doing this until you have a well balance seam. Then clip the colored threads starting with the upper looper thread, tie off to your proper color for your seam pull the thread through and up through the throat plate. proceed in this manner with lower looper, right needle, left needle. Sew a test seam.

Good luck.

Correct settings for 804dsp serger to sew a sweater.


Are you wanting to use the serger to sew a hand knitted sweater together? or do you mean a sweat shirt knit or other knit fabric. If it is the first option, I'd say don't bother, as you can't do it with the blades working because it will cut your knitting and the wool will unravel in the seams.

If it is the second option then I would start with the following settings.

Four thread stitch, so both needles and the upper and lower loopers threaded. Set tension on all four dials to 5, stitch length to between 2 and 3, and differential on zero. Move the cutting blade over to the right for a wider seam. Now test stitch on some fabric scraps double layer and see what the seam is looking like.

Now you want to adjust a couple of things: firstly width of the seam. Is it the size you want? If you'd like it a little narrower, then adjust the cutting blade back a little to the left to narrow the seam slightly - just depends on the fabric weight. For example if it is a loose open weave like boucle you would want a wide seam to make sure it holds the fibres fully.

Now you can adjust the upper and lower loopers to get the thread wrapping around the edge looking nice. Look at the seam and the fabric inside it. Is it tunnelling and pulling up the fabric? if so, release tension on both loopers a half number to put more thread into the seam. Test stitch again and see if the loopers are meeting nicely on the cut edge of the fabric. Upper and lower looper threads should be meeting right on the cut edge so if this isn't happening and one showing on the other side, then tighten the looser one by half a number and test again.

If the threads are hanging off the edge then you have the choice of moving the blade to the right to cut less fabric off, or tightening up the looper tensions to pull in the thread.

That's it, hope this helps you to master your serger.

If you'd like some images and further explanations of other stitching you can do with your overlocker, then Debbie Coswell has some great information on line at www.sewing.about.com, just search "overlocker" to find the specific pages.


Good luck

How do you lengthen stitch. The stitches are so close together it looks like a satin stitch. I have no manual for it. thanks!


your machine should have a stitch length dial on the right hand side above the flywheel, it might have numbers from 0.5 to 3 or 4, higher number for longer stitch (effectively this moves the foot and feed dogs faster in relation to the needles to make the stitch longer).

If you have the Serge Pro SW432 that your enquiry is linked to and you have not used a serger before, then definitely get hold of the manual, you will need it. Sergers are very different to sewing machines - once you've mastered one, its easy, but there is a learning curve.

Firstly, ALWAYS extend the thread aerial up, you'll see loads of images of sergers sitting nicely with the aerial in the lowered position, great for moving them to avoid damage. But they won't work well, a serger seams at 1500 stitches per minute and the thread streams off the cones so you need to ensure there is a good clear feed via the aerial to the tension dials.

Buy good quality thread cones and keep it out of the sun and dust. Cover your machine when not in use (lower the aerial first). You could start with white, grey and black thread as this will cover a lot of fabric prints/colours etc. To change thread colour, you will need to cut and knot on the new thread for the two loopers (right hand side cones) - do this about 6 inches above the first thread guide, and then chain off to feed these through down to the needle plate, when you see the new colour come through okay, stop. Repeat the process for the needle thread or threads (3 or 4 thead depending on what stitch you are sewing) but stop chaining when the thread knot is above the needles. Stop, loosen these tension dials and pull the thread down, cut out the knot with scissors and thread the new colour through the two needles. Use threading wires if you have them, or tweezers. Pull both these and the two looper threads together under the pressure foot, lower the foot, turn your tension dials back to 5 and chain off. The thread sequence is important, mostly top looper, bottom looper, then needles, this is so much easier demonstrated than explained.

If you can find a classroom/shop offering overlocking user lessons, go take a couple, its well worth the money. Otherwise go to you-tube and watch all the videos you can search on sergers, threading, etc.

Good luck with your serger, please respond with 4 thumbs if this has been helpful to you. :-)

I need to switch to rolled hemming and can't find my manual


Is this on a serger?

Rolled hemming on a serger is usually achieved by doing the following: thread up for three thread overlock using right hand needle. Move blade to the right to trim fabric wider (so it rolls inside the seam). Put woolly overlock thread through top looper (this gives a smooth finish to the rolled hem). Loosen off top looper and tighten up bottom looper so the bottom looper is up tight against the needle thread on the underside. Test serge to get the stitch right, then turn the stitch length down to 0.5 to close it up tight (this uses loads of thread so I usually get everything else right first, then make this final adjustment). On my Bernette 334D tensions are R-Needle - 5, Top looper 7-8 and bottom looper is 3-4. Stitch length 0.5, differential zero.

And usually you flick a small lever or change a little finger on the foot or plate where the stitch forms, there is some variation here between models. Early Elna L4 and L5 locks you had a little finger you changed with a screwdriver on the pressure foot. Bernette has a little slide mechanicism near the blade that you flick forward to engage.

Hope this is of assistance to you - I went for a 2 hour lesson on my serger when I bought it and then came home and repeated all the techniques shown and then made notes and stapled all the stitch samples into a notebook so I could remember how I did it.

Also there are some great books on Serging, Nancy Zieman is one name that springs to mind. Or try You-Tube, she has some videos up there too showing different techniques.

JUKI MO 134 SERGER


How to Thread Juki MO-134 Serger from watching lady at Lyles. Turn upper blade up. Push in first then turn up.It makes threading easier. Blue Thread upper looper first. Pull thread through tension knob. Don'tjust lay it there. (She thought that is what I must have done) Orange Thread lower looper next. Pull thread through tension knob as inthreading upper looper. Adjust lower looper so it is right nextto upper looper so that their points are almost together and directly belowsewing needles. Lower looper will be in front of upper looper (I believe). With tread from upper looper pulledback, slightly lift lower looper above upper looper and thread. I think this isright. Pull thread back with other thread. Tension is the key. Remember that. Yellow: Thread left needle first.Remember tension. Pull thread through curled wire on left side of needle arm. Green: Thread right needle. Rememberabout tension. Pull thread through curled wire on right side of needle arm. b> Note: Before sewing turn the wheel tomake sure the stitches are going together correctly.

Threading rl-635 serger--wife is trying to tread this machine and the lower something or other doesn't work. Cannot find a manual, and the tape they sent with the machine is all messed up.


Sergers can be a bear! One miscue and - well you know. My old serger was threatened more than once.

Are the instructions for this model printed on the inside of the door or on the machine?

Note every guide and make sure none are missed.

Raise the thread antenna to it's highest position.

Raise the presser foot and turn the tensions to zero.

Start threading with the upper looper, making sure the loopers are not crossed.

The upper looper is the one that appears to be taking the thread toward the needles.

Make sure the threads do not cross as you then thread the lower looper (this one appears to be taking the thread away from the needles).

Lastly - thread the needles; right needle first.

Take the ends of the thread under the presser foot and toward the left side of the presser foot.

Lower the presser foot and set the tensions back to 3 - 6.

Stitch a chain of thread before stitching fabric.

If this works, and I sincerely hope it does, never let the serger run out of thread.

Snip the thread near the cone and tie off snugly with the new thread.

Lift the presser foot and open the tensions and stitch or gently pull the thread toward the back of the serger. The knots should clear all but the eye of the needles - stop, cut before the knot reaches the eyes

I have a acme serger 5, brand new. We have threaded it according to the cd, I even had my son do it also, but the one of the bottom loopers thread keep breaking. I bought serger interlock thread. It will...


I will make this easy first always thread the machine upper looper then lower looper then the needles if a thread breaks especially if it was one of the loopers, make sure to pull the needle thread out before hand then rethread. as for the breakages look to see if the loopers are hitting each other when they cross and see if the needles are hitting the loopers when they go together either of these things will cause problems if so it will need to be looked at by a tech

Threading an Empisal Overlocker - Model S4D


All sergers thread the same way and sergers have to be threaded in a certain order. I made a jingle out of it...
upper looper
lower looper
right needle
left

It would be best to have a tweezers handy to help with the thread and threading.

always be sure the lower looper thread goes over the top of the upper looper then out the back. I would be surprised if your thread guides are not color coded.
If you look at the top thread guides or the spools. First from left to right thread the 3rd spool, then the fourth spool. Then you thread the right needle (the second spool) then the left needle (1st spool.
The lower looper can be tricky because you have to thread it from the back of the looper to the front.
Pull the threads out the back from under the foot. Then go ahead and run it slow watching to see if it starts making a chain. It should. If not do it over again.
Good luck
