Hi There

I just received a 10 year old Janome MyLock 504D.  It works fine, on the most part, but sometimes it has inconsistent stitches.  I took a piece of cotton and flossed it between the tension disks to remove any lint, as well as cleaned and oiled the rest of the machine according to the manual.    I checked the treading and ensured that the thread is placed correctly between the tension disks.  Any idea on how to fix this?

Thanks so much!

JB

Re: Serger (Over Lock) Inconsistent Stitches

Dear JB,

Some ideas I have that you can try to see if there are any improvements in the consistency of your machine stitches are:

  • Opening the looper covers in the front and the side and vacuuming these areas using the hose of the vacuum, you can also vacuum the thread tension discs. 
     
  • Making sure that the machine is threaded according to the manual.
     
  • It is also best to use smooth threads.
     
  • When sewing try to keep a steady speed. Fluctuating between high and low speeds may cause inconsistencies in the stitching.
     
  • If the blade that cuts the fabric as you sew, is worn out and blunt, it may also cause problems with the stitching.
     
  • Make sure you have new needles in the machine.

Try to make these changes, if you still have issue with the stitching you need take it in for repair.

Hope this helps,

Nehzat
