What are the key safety warnings I should be aware of when using the oven?

The appliance and accessible parts become hot during use, and children under 8 must be kept at a safe distance unless continuously supervised. The oven must be switched off before replacing the bulb to avoid electric shock, and a steam cleaner must never be used for cleaning. Do not use rough, abrasive materials or sharp metal scrapers to clean the oven door glass, as they can scratch the surface and cause the glass to shatter. The appliance should not be powered by an external switching device such as a timer, to avoid danger from accidental resetting of the thermal interruption device. (Page 2)
