Serger Machine My serger machine is running with a kind of hammering noise. I am suspecting that its timing is out. How can I fix that?

    I could not wait any longer. I sent it out to a shop for repair.

    I have the same problem, but I know that the upper and lower loopers are touching, and the needle is hitting the lower looper. It is not forming a stitch even though rethreading, etc. Is this my timing? Can I fix this if I am mechanically minded? I'm a poor person.

    I am having the same issue. I unthreaded the machine and have inspected where the problem is. The left needle comes down and I hear metal touching metal and see that the needle is in fact hitting the lower looper. I have a 4 thread shark europro machine and it is about 4 months old and I have sewn several things but, recently broke the needle I have the manual and I have repeated the instructions for replacing the needles over and over and I just need information on the adjustment to fix this issue? Any information is appreciated!

If the timing is "out", you will not be able to form the chain stitch.......do a sample to see that you have all 4 or 3 threads involved in forming a complete stitch.........if you do, then it is not timing.

I suspect there is a likely collision of parts, there are several possible contenders, tolerances for most are very small, 0 - 0.2mm, so a very good light and magnifying glass are useful, as is good hearing for when the click or clunk happens....

While slowly moving the handwheel manually, rocking back and forth and/or full rotation.....remove all threads for this..., carefully observe:

> the two loopers should almost touch as they pass each other

> lower looper should almost touch the needle/s as it passes

> is lower looper needle guard colliding with either needle/s or upper looper

> are feed dogs colliding with needleplate

> are knife blades burred, check for smooth surface/s

> are loopers burred (gently run finger along looper up to & over the point, on all 4 surfaces they should be smooth & free of "lumps")

there may also be a load of lint inside the base.......if you open this, be ready with vacuum and do it over newspaper with machine on its back.......use a small brush to assist.

also,

are your needles new and sharp

if you have sewn through pins, things can go out of balance, or get jammed inside.

Does the handwheel feel free all the way around, or is there a "tight" spot......where is everything (relative position of loopers, needle/s) when this happens, is anything obviously holding back the movement, or clicking as it passes....is it in the same place at each rotation ?

Once you have a better idea of the specific area/s of concern, post back with lots of detail and maybe a photo, and we shall have another go at specific resolution........at this stage, there are too many variables to say straight off what it is causing the noise.

Happy hunting......

I have a brand new brother's serger 1034D.. Its new.. as in never been used but once but it's not in warranty. It's making a grinding noise. I've liked it and is clean. Any ideas what's wrong??


Could be that since it has set for years without use or maintenance, the old oil has dried out and the motor is straining to run the machine without sufficient lubrication. Trying to run the machine in its present condition could damage the motor. Your machine very likely just needs a thorough oiling (1-2 drops of fresh good quality serger oil) every place that metal rubs on metal. (Sergers usually take a lighter-weight clear oil--different from what sewing machines would use.) You should probably throw out the oil that came with the machine. It is probably old and should not be used in your machine.

A serger requires much more frequent oiling (the moving parts behind the front door, ie the looper mechanics, etc.) than a sewing machine. In addition, about every year I take the bottom off my serger and lube the moving metal parts inside with Tri-Flow Synthetic Lube. It has a whole different sound after getting some TLC!

To keep your serger operating for years, be sure to regularly clean and apply a couple drops of lube as recommended in the owner's manual (maintenance section).

I bought a second hand babylock eclipse serger, the pproblem is the width sticth adjusment is stack, how do I slove it.


Just guessing the machine may need cleaning and oiling. Consult the owner's manual. Sergers usually require frequent oiling (more than sewing machines) because of the speed and complexity of moving parts in a serger. Apply 1-2 drops of fresh, good quality oil for your machine--some brands use a specific weight oil.

If in doubt, take it for service. It could probably use a very good check-up by a professional anyway. At least then you will be starting out with a tuned up, working machine.

cleaning your serger (avoid using compressed air as sometimes it will force lint and debris farther into the machine!)

Since your issue is with the stitch width function, you may want to focus more on that mechanism and work at getting it released. Sometimes applying heated air from a handheld hairdryer will loosen stuck mechanisms.

Does the Singer Serger Ultralock 14u52a use standard needles or do I have to get special ones?


Serger needles are different from regular sewing machine needles, but like sewing machine needles, they are generic. That means that if you buy a serger needle, it should fit most sergers from any manufacturer.

My favorite manufacturer is Organ; they've been in business for a long time and manufacture for commercial and home machines and sergers and they're quite inexpensive.
