Hey, got a suggestion to try this forum from a friend as I'm out if clues as to what is happening with my overlocker. On the wrong side of the fabric my left needle stitches are being pulled into my right needle stitches. I've checked and rechecked my tension dials. It's not a tension problem just for some reason the left run of stiches is being incorporated into the track of the right needle stitches. Any ideas anyone? I've got through about 5 metres of fabric tweaking tension dials and test sewing! I'm still a novice so please don't laugh me put the forum if this is obvious! Thank you so much for any help!
May I introduce you to the book that never left my serger table
the first year I had my machine: Ultimate Serger Answer Guide.
Good instructions, and excellent pictures of what's going
on with poor stitches, possible causes, and how to fix it.
Yes, it's old. But your serger is very similar to the sergers
of the mid 90s.
Wild guess: the left needle thread isn't being tensioned
properly... probably not sitting in the tension properly or
a dirty tension or tension setting off.
But let's try my basic troubleshooting algorithm, which
fixes most machines without driving you nuts:
First rule of serger troubleshooting: The threading is off.
Second rule of troubleshooting: It's dirty.
Third rule of troubleshooting: The needles are dinged up.
So... I'm going to suggest that you stop right now.
Take ALL the thread OFF of the machine.... yes, cut the
threads and run out the chain. Take all the
cones off. Clean the machine per your manual.
You're looking not just for fluff and drippy oil and
yuck, but evidence... like the end of a bit of
thread hanging out under the thread stand, or out
of a tension. Oil per your manual's recommendations.
New needles, right size, perfectly placed in the
needleholders, all the way up before
you tighten the screws. Yes, this may feel wasteful
but you can always save those needles for later...
right now, we're trying to get the machine happy again.
Next, make sure the thread tree is all the way up and properly
aligned with the front of the machine.
Now, dig out the threading section of the manual, and proceed
to thread the machine from scratch *in the order* specified
in the manual. If it says "raise the presser foot", do so.
As you place each cone on the machine, run the thread through the
thread tree and around the first tensioning device (usually a bar
above the tensions) and give the end a little tug. All four
threads should feel at about the same tension.
Even though it'll make you feel like a fool, read each step
of threading *out loud* before you do it. It's amazing
how often you catch yourself doing something by rote that's
different from what the manual says. My hypothesis is that
reading the steps out loud give your fingers a chance to catch
Once again, check the tensions -- pull each thread a bit
after it's been through the actual tension dial or slot, and
make sure they're set to the default for the stitch
you're doing on this machine.
Now try a sample. Still doing it? Or is it "cured"? Most
of the time, the machine is cured except for maybe some tiny
Woah Kay, thank you so much for this incredibly comprehensive and useful reply. A good hit list to get going with. I'll do as you suggest and fingers crossed it'll all be sorted! I'll update. Once again, huge appreciation you legend!
