Grip the black plastic lever nub firmly and carefully remove it from the metal lever. Use one hand to hold the toaster in place while you pull the lever nub with the other.
If this is the first time detaching this piece, it will take some effort to remove. Be careful as pulling too hard can cause damage to the inner lever mechanism.
Flipping the toaster upside down, use a T7 Torx Screwdriver to remove the four 10mm screws that keep the outer shell attached.
Flip the toaster back over and slide off the shell making sure to slip the toaster lever (now without the black plastic nub) through the lever opening in the shell.
The outer shell should now only be connected by its internal wiring.
Locate and remove the two 8mm screws that attach the circuit board (located inside of the shell) from the shell itself using the Phillips #2 screwdriver.
The shell should now be completely separated from the rest of the toaster.
Upon removing the chassis, look in the toaster base to find the little white tab holding the power cord in place. Use a Philips screwdriver to remove the two 10mm screws.
