Does the sandwich machine need to be oiled for bread?

The sandwich machine should be oiled on the bread, and the bread can be smeared with butter or not, depending on personal practice.

Put two sandwich trays into the sandwich maker. A click will be heard if the tray is inserted correctly. Lightly butter or oil a baking sheet; turn thermostat to "setting" and toast sandwiches. Insert the plug into the wall socket, the red operation indicator light and the green roasting and grilling indicator light on; prepare the material for toasting the sandwich; when the green light is off, the product is ready to use. Lay the bread on both sides, buttered side down, and place the filling on top of the bread, then place the other two slices on top, buttered side up. Turn off the sandwich maker; after 4-6 minutes, turn on the sandwich maker; take the sandwiches out; unplug after use.
