Question about Bosch Home & Garden UniversalGrind 18V-75

Protective cover mounted the wrong way round? Hello Either I'm just stupid or there's something really wrong. I'm already failing when it comes to fitting the protective cover: The inlet gaps on the machine side are arranged in such a way that I think the protective cover would be the wrong way round, namely at the front instead of the back. This means that the disc cannot be used at all. Could it be that the mounting part has been fitted the wrong way round at the factory? Or am I simply missing something? Greetings Pesche
