Sewing Machine & Serger Problems

If you are experiencing stitching problems with your sewing machine and serger, try raising the presser foot BEFORE threading the upper thread. This releases the thread tensioner while threading, but when you lower the presser foot, the tensioner is activated to control the thread's tension.

Never remove the upper thread by grabbing the spool and pulling the thread tail backwards through the needle eye, thread guides, and tensioner. To remove the upper thread, clip the thread below the spool, raise the presser foot, then gently grab the thread tail by the needle's eye and pull the remaining thread through.

Hello I just got a new home My Lock 334D machine. It has Seized intermittenly. could we troubleshoot the problem & fix it together?


Un-thread and then see if the machine will run without thread.

If not, it needs to go into the shop for repair.

If it does, refer to the manual. Or, the guide that should be printed on the inside of the serger's door.

Raise the thread antenna to it's highest position. Keep it at this position when serging. If lowered for storage, and threaded, be sure the thread does not tangle around the antenna arms.

Raise the presser foot.

Open/set the tensions to zero.

Raise the loopers to their highest level - there may be an indicator mark on the side of the serger to match with a mark on the handwheel to help with this.

Start threading from the right to the left; upper looper first.

After threading, reset the tensions to a medium number, lower the presser foot and stitch a chain to test the stitching.

Serge a scrap and adjust the tension as necessary.

Once you get the serger working as it should - don't run out of thread. Tie off, open the tension, raise presser foot and gently guide the new thread through the threading process.

When changing the thread or removing the thread to store the serger, cut the thread at the antenna, leaving thread tails for tying off the new thread.

If you do not have Nancy Zieman's "Serge with Confidence", you will find it much more informative than the average serger manual.

how do you thread a elna L-5 sewing machine


I found two sites with a manual for this model. Both are around $15.00 - sew4less and sewusa.

If you open the front of the serger, there should be a threading guide printed on the serger or on the inside of the door.

Raise the thread antenna to it's highest position.

Set the tensions to zero and raise the presser foot.

Turn the handwheel until the loopers are at their highest position - the handwheel may have a mark on it that aligns with one on the side of the serger to help with this.

Starting at the right, thread the upper looper first.

After threading, reset the tensions back to approximately mid-range.

Lower the presser foot and stitch a chain of thread to make sure the serger is stitching as it should.

threading rl-635 serger--wife is trying to tread this machine and the lower something or other doesn't work. Cannot find a manual, and the tape they sent with the machine is all messed up.


Sergers can be a bear! One miscue and - well you know. My old serger was threatened more than once.

Are the instructions for this model printed on the inside of the door or on the machine?

Note every guide and make sure none are missed.

Raise the thread antenna to it's highest position.

Raise the presser foot and turn the tensions to zero.

Start threading with the upper looper, making sure the loopers are not crossed.

The upper looper is the one that appears to be taking the thread toward the needles.

Make sure the threads do not cross as you then thread the lower looper (this one appears to be taking the thread away from the needles).

Lastly - thread the needles; right needle first.

Take the ends of the thread under the presser foot and toward the left side of the presser foot.

Lower the presser foot and set the tensions back to 3 - 6.

Stitch a chain of thread before stitching fabric.

If this works, and I sincerely hope it does, never let the serger run out of thread.

Snip the thread near the cone and tie off snugly with the new thread.

Lift the presser foot and open the tensions and stitch or gently pull the thread toward the back of the serger. The knots should clear all but the eye of the needles - stop, cut before the knot reaches the eyes

Need instructions for threading Juki MO 3314


Open the font of the serger and the instructions will be printed on the serger or on the door.

Raise the presser foot and set the tensions to zero when threading.

Turn the hand wheel so the upper looper (curved one) is at it's highest point and thread it first, and then the lower looper.

With some sergers you must thread in a certain sequence. This should be indicated in the instructions on the serger.

Set the tensions back to normal ( 4 - 6), lower the presser foot and run a length of stitching to see if the threads are knitted together as they should before you start serging your project.

threading a husqvarna huskylock 1001L serger


Solution taken from "Handbook for Huskylock Sewing Machine Models 1001L/1000L/1000"

1. Raise the presser foot by using presser foot lever. When the presser foot is raised, the two thread tension discs in the thread tension control panel are released so that thread passes freely between them. Otherwise thread tension may not be correct.

Important! When threading the needle, always be sure to lift the presser foot lever, and also take care to thread in the proper order.

Threading order:
1. Upper looper thread (green)
2. Lower looper thread (blue)
3. Double chain stitch looper thread (purple) in case of 5 thread stitch or double chain stitch
4. Right needle thread (red)
5. Left needle thread or double chain needle thread (yellow)

Caution!
Because the left thread tension dial (yellow) is used for either the left needle or the double chain stitch needle, these needles will never be used at the same time.

Upper looper (green) sequence:
1. Thread holder (silver triangle openings attached to thread holder stand)
2. Thread guide (flat silver clips just behind thread tension disc)
3. Thread tension disc (circular knobs with numbers for tension setting)
4. Pull thread around upper looper guide and upper looper
5. Pull thread into hole of upper looper

Lower looper (blue)
Repeat 1, 2, 3.
4. Pull thread around guide (see color coded chart inside front serger cover).

Easy threading mechanism (for lower looper)
1. Pull out the lower looper threading lever
2. Thread the lower looper and position the thread on hook of the lower looper
threading lever.
3. Push the lower looper threading lever back to its basic position while
holding the end of the thread.

Caution:
When returning the lower looper threading lever, always make sure that the two
blue triangle marks (directional arrows) meet each other.

Right needle thread (red)
Left needle thread (yellow)
Important: Thread the needles after threading of lower looper and upper looper.
First raise the presser foot lever, and then thread the needle threads in order shown in color coded thread guide.
