The goal is to get the blades and the puller arm to align properly, so there is even pressure and spacing from side to
side.
If the blades and puller arm are aligned correctly, but you are still not able to complete a successful cut of the thread,
it may be time to replace the wave washers.
Wave Washer and/or Cutting Blade Replacement
Tools needed: APQS Parts:
#2 Phillips Screwdriver – short handle Wave Washers x 6 2200-01 (most common)
Flat Blade Screwdriver – small tip Thread Cutter Blade x 2 2210-01 (less common)
Time to complete: Approximately 10 minutes
At some point, you may not be able to adjust the thread cutter so it cuts your thread. It is most likely not because the
cutting blades are dull - it may be because the wave washers have flattened out. The wave washers allow the blades
to spread apart and allow the thread to be pulled into the blades, but keeps enough pressure on the blades so they
can cut even the thinnest threads. This can also happen if the blades are tightened too much, or if lint build-up gets
‘packed’ between the washers. The process to replace the wave washers begins below.
If you have not already done this in a previous step, you will need to move the needle plate off to the side of the
machine so you can work on the thread cutter.
