Question about Necchi Sewing Machines

Open Question

I have a NECCHI type 554 sewing machine that the pattern selection dial is stuck. The only way I can move it is if I take the top cover off and use a screwdriver to push the arm down. I can't seem to find any logical reason it should be sticking. I need to know if there is an easy solution or if I need to take it apart.

SOURCE: stitching looping

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.....the question you pose could have 2 meanings....this reply is for looping thread.

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....

cc3f045.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.

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. ie a different colour top and bottom just for the test.

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 consistant diameter with good thread, and less compensating to be done by your tension plates and less thread breaks !

I have the Necchi # 537 running now ,it was like you said I cleaned the old dry oil out ,however I do not have a book with it to tell me where to oil it ,can you help me ,Thanks


If it is an old mechanical machine, apply a drop or 2 of oil every place that metal rubs against metal. (Gently wiggle the handwheel and watch where things move.) Do NOT oil belts, cams, or plastic gears. After oiling the top of the machine, don't forget to take care of the moving parts in the lower part of the machine! The move the levers and dials and oil those moving parts too.

Applying heat from a handheld hairdryer may help speed up the process.

Is it possible to change the presser foot pressure on a necchi 200? I looked in the manual but can't find anything.


Newer computerized models usually have a pressure adjustment in the form of a dial on the left side of the sewing machine head.

Older machines generally did not include that information in the manuals. It is usually a screw that is accessible from the top of the machine, inside the cover--most often directly above the presser foot. Sometimes it is a plunger-type button--the further down it is depressed, the tighter the pressure.

FWIW, if your machine does not have a pressure adjustment, you might try using other presser feet, ie roller foot, walking foot, teflon foot.

I have a necchi 4595, and well I cannot figure out the straight stitch....the dial doesn't show one?


It's just in the front panel, where the drawing of all the built in stitches are, it's the drawing number eleven from the left, you'll see a zig zag (red) and a straight stitch (black) Select A group of stitches (knob with the arrow) and then select the eleventh stitch (same knob but use the dial, look the manual) and then select zero on your stitch width dial. Hope that helps :)

Thread jamming, wont feed material, sewing in one place


Try moving the stitch length dial to 4 or 5 - check the manual. You may have it in the position for very close together sewing. I had to do a lot of trying with my 4795 to get it to work right. I found that very thin thread, polyester kind, broke at the needle after a couple of stitches. I switched to coats & clarks thread and a Singer ball point needle and it works fine. Be sure your needle is inserted with the flat top toward the back of the machine. Good luck!
