Overheats and stops oscillating

@sudsy25427 seized bearings or a bad gear assembly would be my primary suspects. Time to tear your Bosch down and take a look at what is going on with it. Since iFixit does not yet have a specific guide for this, use something like this video Let us know what you find out. If you do need further help with this, post some pictures of what you are looking at with your Question Aggiungere immagini ad una domanda

While you work on your Bosch, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
