5. Maintenance and
Repairs
Readjusting the
door
The oven should, at reasonable intervals, be tested
for proper operation. This applies especially to the
temperature limit cut-out/controller.
The safety of the oven and its conformity with the relevant
standards will be guaranteed only if maintenance work,
repairs and/or modifications are carried out by authorized
personnel.
Before any maintenance or repair work is carried out, the
oven must be disconnected from the line.
If the door no longer closes properly, adjust the
bearing pin and the catches:

Adjusting the catch
2.Adjusting the
bearing pin
Loosen the catch nut M6 with a wrench (size 10) and
turn the catch clockwise for at least one complete
rotation.
After this, return the catch to the same position.
Retighten nut M6.
Loosen the Phillips screw of the bearing pin.
Use a small spindle to prevent the bearing pin from
rotating also. After you've loosened the screw, turn the
bearing pin with the spindle, and determine the desired
setting for height and depth. Retighten the Phillips screw
and check if the door fits tight.
