EXTRAORDINARY MAINTENANCE

5.1 PRELIMINARY SAFETY OPERATIONS
WARNING! Before carrying out any maintenance operation,
disconnect the power supply by switching off the switches installed
outside the oven and/or leavening compartment and wait for the

night or if visibility is poor.
All maintenance operations and repairs must be carried out using
suitable accident prevention equipment, by specialised and
properly licensed technicians, approved by the manufacturer.
All precautions are to keep the appliance in a proper state, and
failure to observe them might result in severe damage that will not
be covered by the guarantee, and in unnecessary risks.
