White Sewing Speedylock 1600 Mechanical Sewing Machine - Answered Questions & Fixed issues

You can get sewing machine manuals online at sewingmanuals.com. I didn't see the superlock 2500 but there were other superlocks. They may thread the same way.

I think that you must have some of your fabric and lint in your machine. Take a brush ( I use a new paint brush and clean your machine looper areas really well, oil then Totally rethread, take your thread for each guide and treat it like floss going into all of the grooves so that they are seated properly. This should do it, getting your thread seated is the most common problem with overlockers not chaining.

Depends whether the thread is breaking or pulling out.Usually, timing causes the threads to miss stitches. And, yes, timing can be repaired.Remove ALL the thread from the machine and rethread from the beginning. Be sure to ALWAYS raise the presser foot when threading. This releases the tension disks so the threads will seat completely. However, it also helps to give each thread a little tug and sometimes the thread will pop when it seats.If thead is pulling out, be sure to pull a lot (at least 6") of thread tail through before beginning to stitch.If the thread is breaking, check that it is threaded correctly and that each thread is threaded in the proper order (usually upper looper first, then lower looper with the thread draped OVER the upper looper). Threading in the wrong order will almost guarantee it will not work. Also check that the tensions are not set too tight. Generally, to start out, set all the tensions at the midway point....

Search the internet: Brand + Model + the word "Manual" ...

If the handwheel is really stiff and the machine is making awful noises, then your machine may need oiling. Don't know if this is the case with your industrial machine, but it may be something to consider.

Servicing the Timing is NOT a home fix

Timing issue, take for a Service

Push and hold the reverse button for 7 seconds and see if that fixes it.

All serging machines run in reverse, the hand wheel turns reverse compared to regular straight stitch machines which run counter clock wise. I need more information, My email is [email protected].

Try removing thread #3 from the tension altogether. If this doesn't work, then try using a different spool of thread. Some break easier than others. If this doesn't work, try rethreading your serger from the the beginning. Upper looper first, then lower looper, then needle. Test on scraps.

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!!!!

SKIPPED STITCHES ON A SERGER1. Is the needle bent or worn--replace2. Is the needle inserted correctly into the needle holder--check needle3. Is the Serger threaded correctly--rethread 4. Is the presser foot pressure right for the fabric--adjust 5. are the needles the correct ones for the serger6. Possible timing problem--need to be checked at a sewing machine shop

What is the make/model of your machine?May need a good oiling.

I have a 1500 with a manual. I could copy the manual and send it to you. Email me at [email protected]

yes, take all threads out, and re=thread according to the diagram, following the threading order.

what ever fabric you use the tension must be adjusted if nessaryhere are 2 links for a free manual from singer pick the one best foryouhttp://www.singerco.com/uploads/download/754_sl-1600-x.pdfhttp://www.singerco.com/uploads/download/979_sl-1600-x.pdf

Your machine cannot do a cover stitch. Check the Brother website, they make a cover stitch only machine, it works much better than any of the serger/cover stitch combination machines, and it is a lot less money.

Been there, done that. Old serger almost went out the window more than once.

Raise the thread antenna and loopers to their highest positions.

Set the tensions to zero. If your serger has auto-tension, raise the presser foot as this also opens the tensions.

Begin threading from the right as indicated in your manual or on the door of the serger.

If this continues, the serger may need to be serviced as the timing could be the problem.

Ask before leaving the serger as the service cost usually starts around $100.

I finally gave in and bought a Babylock with instant jet-air threading.

On www.sewingpartsonline.com they list the White elasticator foot as no longer made or available.

Singer has the manual for the White 7340 on their site, http://www.singerco.com/accessories/instruction-manuals . Enter the model number and click Search. The direct link to the manual is http://www.singerco.com/uploads/download/988_sl-7340,299-x.pdf . A universal cord and pedal are avalable here: http://www.sewingpartsonline.com/white-7340-sewing-machine-parts.aspx . This site also has a printed copy of the manual for sale.

I hope this helps.
