Caution!
Risk of injury due to hot and sharp-edged parts!
The O-ring cutter cuts the seal with a hot metal tip. This process heats up
the seal and possibly also metal parts of the valve.
► When removing the valve seat seal always wear heat-resistant protective
gloves.
Carry out the following steps:
1.
Place the heated metal tip of the O-ring cutter at right angles on the valve
seat seal to be removed.
2.
Cut through the valve seat seal at one point using the O-ring cutter.
!
Pay attention not to damage the edge of the radial groove.

It must be ensured that the circumference of the seal can be deformed
without major effort. The required warming-up time depends on the individual
oven and can vary accordingly.
