    • Toaster will be turned upside down. Clear crumb tray or work over a paper towel.

    • Turn the toaster upside down.

    • Unscrew all four 4mm screws on the bottom using a Phillip's head #2 (PH2) screwdriver.

    • Or a slightly different model has six screws that require an allen wrench (hex key). Ones that have a ball end will not work. I had to use one that had more of a Star of David, pointy pattern to it.
