The threads are no longer looping

I have a 4 thread speedylock and all of a sudden the threads are no longer looping together. My machine is threaded correctly and I have tried adjusting the tension. What else should I do? FYI repair man said it would cost $150.00 for him to look at it and fix...........

Re: The threads are no longer looping

To thread the overlock you start with the inner most looper first, then the outer looper, then the inner most vertical needle and then the outer. This is the order: | | | | #4 #3 #1 #2 You have to ensure that the lower looper (the furthest one out) has the thread going over the slightly higher looper, the first one you did. If you do this you will be making a stitch. To make the loops fall close to the material is simply a case of altering the tensions on all the needles - I have to do this with my wifes machine. Once I have the tensions for her machine I'll be able to pass them on to you although every machine is different it may give you a starting point. I will try and perform this task this weekend - I'll be online next week and perhaps we can chat and I can send you our tension levels. I hope this helps.. my wife sews and I re-thread - she won't go near the inside of the machine and I won't try to sew :) BXL830

My white speedylock 1634 the left needle only picks up the loop every 3 inches.Serger left needle is going in holes are there. I have re-threaded it several times. how can i fix this?

Try putting in a new set of needles. Make sure to fully insert the needles into the machine. If the needles are not set fully into the shaft, or if there is a burr or nick on the needle tip skipping stitches can result. If this doesn't solve your problem, possibly the timing is off and needs to be serviced.

White speedylock 1600 thread keeps breaking

rethread the machine to make sure it's threaded correctly & that the thread is not caught anywhere

put new needles

check the thread tension, it sounds like it's to tight

use a can of computer air & clean out around the loopers area for lint or loose threads

if none of these suggestions work, then having it serviced would be the next suggestion

I own a Bernina 1260 and am having a problem adjusting my bottom thread (it has loops in it). I have tried adjusting the tension but I still cannot get a perfect bottom stitch.


You would pull out several long lengths of matching thread from my spool of thread and knot the threads together at one end (to hold them together). Grab the knotted end of threads with your left hand and place the threads(held taunt together) under the presserfoot of your sewing machine.

Select a narrow zigzag stitch that will zigzag over the threads, and holding both the knotted end(Left hand) and the other ends with right hand( holding tauntly), zigzag down the length of the threads.

You can use this for matching button loops, cording for belt loops, or whenever you need matching cord. The thickness of the cord will depend on how many strands of thread you want to use. You insert the loop of cord into the seam, so that when the garment is turned RIGHT SIDE OUT, the loop will be sticking out of the seam and you can put the button through the loop.

Dear VeeVeeV,
when I've had that problem it was due to incorrect threading of the top thread. Sometimes it "jumps" out of one of the thread guides, particularly the round one with the tension spring. The bottom thread looping & the machine not sewing is my first clue sometimes that it's done that. good luck, Georgia

Tension on my white apeedylock 1600

Is there a thread guide printed inside the machine? have you asked your friends? When you've exhausted every avenue, take it to a dealer and ask them to show you how.

Thread keeps breaking

Your machine isn't threaded properly. Check to make sure #1, you have it threaded right and #2 the thread on all 4 spools is in between the tension dials. Good Luck and Hope this helps.

Keeps cutting the thread from inside the machine

Make sure all of your threads are in between the tension dials. Sounds that the machine isn't catching because of the tension. Good Luck

Treading my serger

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!!!!
