Warning and Safety instructions

Do not use the appliance to heat up or bottle food in sealed jars
and tins.
Pressure will build up inside them and they can explode causing
damage to the appliance, as well as the risk of injury and scalding.

Do not leave the oven door open unnecessarily as someone may
trip over it or be injured by it.

The oven door can support a maximum load of 15 kg. Do not lean
or sit on an open oven door, or place heavy items on it. Also make
sure that nothing can get trapped between the door and the oven
cavity. This could damage the oven.
For ovens with a stainless steel front:

The coated stainless steel surface can be damaged by adhesives
and will lose its protective effect against pollution. Do not adhere
sticky notes, transparent tape, masking tape or other adhesives onto
the stainless steel surface.

The surface is susceptible to scratching. Even magnets can cause
scratches.
