Question about Necchi 6002 Sewing Machine

2 Answers

Singer Ultralock 14U85 left overlock needle position lower than right needle. Can't find anywhere that this is normal, but the left needle just won't go into the slot any further. It worked fine for the 5 thread safety stitch, where the left needle is removed and put in a separate, chain needle position. But once in the left overlock slot, the 4 thread stitch, the upper loops do not reach across far enough to be caught in the left needle stitches. Does anyone have experience with this problem? Is the left needle position ok to be 1/4" lower than the right needle?

One needle does sit slightly higher than the other. The stitches not catching sounds like a tension or threading problem.

One needle setting higher than the other is normal. Just make sure that when you install a needle that you push it all the way up before tightening the screw. Try changing out the needles and re-threading everything from the very beginning.

SOURCE: How to change stitches

You really need the instruction manual. You can order one at several places. I ordered mine through the Allyn Co., who is the present day Necchi distributer now in the U.S.A. You can order by calling them at 1-800-525-9987. They cost $10. & a moderate shipping & handling chargr. Their manuals are pretty informative on the machines, at least mine is.I bought two Necchi's used. One is a 537l & the other is a 525FA. It tells you how to clean & oil it & how often to do it & mine shows you how to set machine for the various results, & tells your stretch from the other stiches, etc.

SOURCE: only does zig zag stitches, no straight stitches,

make sure the pattern selector is set for straight stitch first. If it is set correct then the machine may be "stuck" is zig zag mode. May need to be de greased and then re lubricated.

SOURCE: I've got a Necchi 535FA with a bobbin thread that doesn't hook.

Sounds to me like you may have put the needle in backwards. The flat side should be to the back.

SOURCE: I am hemming blue jeans. The top stitch looks

Please TRY the solution BEFORE giving your considered rating.
Specific detail on bobbin case adjustment (with picture) near halfway down reply, the remainder will help you achieve a balance of top and bottom tensions.

Ensure that all is clean and free of lint and jams, this is the most likely cause....now for tension troubleshooting .......

This solution is for tension problems...if you cannot form any sort of stitch, the issue is quite different, so please let me know if you need a different problem solved.....

It is quite long, but just work through each section in order.

The "knotting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.

QUICK SUMMARY FIRST:
Ensure sharp new needle,
Thread guides and Bobbin are Clean & Clear of lint
Set Top Tesion to 4 ....then....
Balance Bobbin to suit.

TOP THREAD TENSION:
If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your projects).

IS YOUR NEEDLE SHARP ?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !

TOP TENSION & GUIDES:
Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.

It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.

If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.

Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with a see saw / to and fro action.

In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to disengage tension plates).... do not gouge or score the plates, they need a polished surface to work correctly.

BOBBIN TENSION:
Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension.

I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean
the hook race area (where bobbin case sits)

...this is just good housekeeping, my wife does this every time she replaces the bobbin....

just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint. If there is a significant amount of lint, use a vacuum and small brush to get the worst.

Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.

If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned.

TOP LOADER:
Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork....

4c76dc1.jpg ...the other screw at one end is holding it all together, so beware....it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !

FRONT LOADER:
....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all
back properly.
165ca5c.jpg FINISHING UP
GETTING THE BALANCE RIGHT:
When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.

Try using good quality thread of contrasting colours so you can more easily spot the changes.

Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension screw very little at
a time, perhaps 1/16 of a turn.

You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it cannot be correct to do this.....BUT....it is,
and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)

OTHER ISSUES:
If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine
case....no case ? then make some sort of cover !

Same applies in any damp or humid environment, keep your machine dry and dust free.

Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with
dust and form a "clag" like glue (another reason for some sort of cover, even a teatowel !)

FINALLY, A WORD ON THREAD:
If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the
time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistent diameter with good thread, and less compensating to be done by your tension plates and less thread breaks

What setting are the three threads set on for a rolled hem on a singer ultralock l4sh654 and what is the lever by the plate for?


Rolled hemming on any overlocker is usually achived the following way. Right hand needle only.
Blade over to the right usually to cut wider than normal but you can vary this to suit the fabric and stitch width you want.
Thread in this needle and the upper and lower loopers. If you can source any, use woolly overlock thread in the upper looper, this fluffs out when not tensioned and covers the fabric to give the look of solid stitching. Change upper looper tension to about 2 and lower looper tension to about 6 or 7.

The lever by the plate is usually to control the little stitch finger where the stitches are formed, move it backwards and it should move back towards you?? If this happens, then you want it in the retracted (towards you) position for rolled hemming so the stitching is much smaller and the fabric can roll. Normally this stitch finger holds the fabric firm for the loopers to form the stitch over for your normal 3 or 4 thread overlock.

Now test stitch and see how it looks. Tighten the lower looper thread so it lays right beside the needle on the underside. You may need to then tighten or loosen more the upper looper, you want the upper thread to wrap all the way around to the underneath against the lower looper thread and needle.

The cut edge of fabric should roll to underneath inside your seam. Once you've got this happening, turn the stitch length down to 0.5 or so to close it right up tight. This uses heaps of thread so I usually test everything else, then close it up at the end to minimise waste.

Hope this makes sense, good luck.

I have a Singer Ultarlock 14U34 and need to know how to adjust the stitch width.


You can download a manual from this link
http://www.singerco.com/uploads/download/664_14u34b,234b.pdf

Check page 16, changing the seam width is done by moving the cutting blade left or right and using only one needle. So if you want the narrowest seam, use the right needle only, remove the left one, and move the blade as far left as you can. Your manual says to turn machine off at the wall for safety, many overlockers will have a motor cutout when you open the front covers, but its good practice to turn off too. Then you put pressure against the upper moveable blade and swing it up out of the way and make adjustment to the lower fixed blade with a screwdriver in your kit (some overlockers it is a knob you move to move the blade position).

And reverse for a wide stitch, use left needle for 3 thread wide seam, and move the blade far right.

You can also use the 4 thread seam where you use both needles and trim up narrow but the seam will be heavier than a three thread.

Each time you make changes to the amount of fabric being trimmed, you may need to finess the upper and lower looper tensions to ensure the seam is tensioned enough to just meet on the cut edge of the fabric. This is the norm for overlockers, each fabric will behave a little differently so you need to test stitch and adjust a little. Your manual will explain this process too.

I have a Singer Ultralock 14U85 electronic with a bent needle clamp I do not have a Manual so I need a part number to try to track one down. Singer no longer has them available


I have been bailed out by www.sewingpartsonline.com and www.sew4less.com a couple of times for parts on a couple of older machines that I have. They also have manuals for purchase too. I think that I would call them and see if there is a substitute, ie. needle clamp for 14u64 and see if it would work. I know how frustrating it is to try and find parts and manuals, I hate to see a good machine go to waste. Good luck.

I have an older model singer serger Model 14U85 Ultralock. The chainstitch needle set screw hole has stripped. Can that whole piece be replaced on my machine?


Call Singer at 1-800-4singer and see if they can sell you that part. I am sure that they can because they do not change the parts that much on the machines. Good luck

I purchased a used SingerSH654 and am at the "dreaded" threading stage. I have threaded using the book and sitting with the serger using the DVD. My left needle (B) thread will not pick up the lower...


I have had a similar problem with my overlocker and had to adjust the height of the needle by moving it lower.
because one needle was so fussy i use my overlocker with only one needle, which give a good enough stitch for what i'm doing

Singer Overlocker/Sergers require particular threading order. If that does not help you may as I did have to take it to an Authorised repairer. It has to be a Singer Authorised as they have done training...


Sergers thread upper looper first, lower looper second, right needle third and left needle last in that order. If your thread breaks, CUT ALL THREADS and start from scratch or you will not get a good stitch or your machine may jam. It's probably just a "user error."
Good luck.

Could not adjust both looper thread tention on singer ultralock


When servicing these machines I have found that the cover over the tensioners needs to be removed so you can see if there is more adjusting possible. If its a newer serger you would hold the knob somewhere in the middle (4-5) and adjust the knurled part that goes through it. Many times I have had to rebuild these tensioners as they get dirty and need cleaning and adjusting. It may take many tries until you have it adjusting correctly. But it needs to be done.

Singer overlocker


Most likely is the left looper thread is trapping the needle threads.

Remove the threads and start over in this sequence....

Left looper - right looper - left needle - right needle.

If you thread the needles before the lower looper, the needle thread wrapped over the looper will be under the looper thread and will never be free to form a stitch, so the threading sequence is critical.
