22. Front Plastic Panels
Remove the right front panel to access the internal mechanics of the head frame, including the needle and
presser bar attachments, take-up linkage, Pitman, and vibration damping hardware. Remove the left front
panel to access the front main circuit board, thread tension motor, and thread break sensor.
Due to how the left and right front panels interlock, both sides should always be removed simultaneously.
U
CAUTION
: Removing only the front left or right panel while the opposite side is still mounted to the
machine may damage the panels.
