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.
