Regarding accessories compatibility, only the AT647 multifunctional bowl supplied with the Cooking Chef Premium is not compatible with the Cooking Chef Gourmet. This is because it does not have an intermediate output.
The multifunction bowl KAH647 must be used for the latter.
For other accessories, use the KAT002ME adapter for all those that attach to the slow output on the front of the robot. (AT950, AT970,71,72,73,74, AT642,643,644, MGX400, AT910, AT941).
