During manufacturing, the toasting elements can have dust that needs to burn off before first using your toaster. Please follow the steps below:
  1. Without inserting any food into the bread slots, push the bread lever all the way down until it locks. (The cartridge will not lock if the toaster is not plugged into a power source.)
  2. The first toasting process will preheat the new elements and burn off any dust, which may have accumulated during storage. It is normal for this burn off to create an odor.
Your Oster® toaster is now ready to use.
