 WARNING
NEVER cover any slots, holes or openings in the oven bottom or
cover an entire rack with materials such as aluminum foil. Doing so
blocks air flow through the oven and may cause carbon monoxide
poisoning. Aluminum foil linings may also trap heat, causing a fire
hazard.

Do not obstruct the flow of combustion and ventilation air.

This oven must only be used for cooking food. Corrosive
chemicals and vapors as well as fumes, vapors or heat given off by
glues, plastics or flammable liquids and materials could be
hazardous. Do not use it as a dryer, kiln, dehumidifier, etc.

Do not let metal objects (aluminum foil, pans) come in contact
with the heating element.

Make certain that the power cords of small appliances do not
come in contact with or get caught in the oven door.

Risk of injury caused by hot surfaces. The oven gets hot during
operation. You could burn yourself on the heating elements, oven
compartment, accessories, or food.
When the oven is hot, use pot holders to insert, remove, or turn food,
as well as when adjusting the oven shelves, etc.

To avoid fueling any flames, do not open the speed oven door if
smoke occurs inside the appliance. Interrupt the process by turning
the appliance off and disconnecting it from the power. Do not open
the door until the smoke has dissipated.

Due to the high temperatures radiated, objects left near the oven
could catch fire. Do not use the oven to heat up the room.

Oils and fats are a fire hazard if allowed to overheat. Never leave
the oven unattended when cooking with oil or fats. Never attempt to
put out oil or fat fires with water. Turn the oven off and extinguish the
flames by leaving the door closed.
