What to do if the WIPER remains out after a trim has completed?

Reasons and Solutions

Important: Please consult the WIPER SET pages in your Parts Manual.

A. Push the wiper back into the Upper Thread Holder.
B. Loosen the lower plus screws on each side of the Upper Thread Presser Base. These are the screws that hold the Upper Thread Presser Base at an angle.
C. Maneuver the Upper Thread Presser Base until the wiper moves smoothly through it without getting stuck.
D. Tighten the Plus Screws.
