SPECIAL MAINTENANCE
5.1
PRELIMINARY SAFETY OPERATIONS
WARNING! All maintenance operations and repairs must be carried
out using suitable accident prevention equipment, by specialised and
properly licensed technicians, approved by the manufacturer.
Before carrying out any maintenance operation, disconnect the gas
supply by turning off the main supply tap, and disconnect the power
supply by turning off the switches fitted on the outside of the oven
and/or the leavening compartment and wait for the appliance to cool
to room temperature.
Always use suitable protective equipment (gloves, eyewear... ).
All precautions are of importance to ensure that the oven remains in a
good state, and failure to observe them may result in serious damage
which will not be covered by the warranty.
WARNING! Periodically (at least once a year), and every time
operating malfunctions occur, the appliance must be checked by a
specialist technician who must check the general state of the
appliance, and in particular the state of the burner. In the presence of
any type of irregularity the burner must be replaced immediately.
When any maintenance operations are carried out on the gas circuit,
use LOCTITE 577 as a sealing agent.
WARNING! Some operations, listed here below, need to be carried
out by at least two people.

soapy water, if necessary. Rinse and dry the areas, being sure to wipe
parts with satin finish in the direction of the finish.
WARNING! Carefully clean off regularly any fat or grease that may
