11.2
Removing the door
Open the door completely and fit the pins (supplied) into the holes from
the inside. Close the door to an angle of about 45°, lift it and remove it
from its seat. To replace, fit the hinges into the grooves provided, then
lower the door until it comes to rest and extract the pins. If the pins are
lost, two screwdrivers can also be used.
11.3
Oven door gaskets
The door gaskets can be dismantled for thorough
cleaning of the ovens. Before removing the gaskets
the oven doors must be removed as previously
described. With the doors removed, raise the tabs at
the corners as shown in the figure.
11.4
Lubrication of gas taps
With time it may happen that the gas taps get blocked and hard to turn.
Clean them inside and re-grease them. This operation must be done
by a specialised technician.
