"Hi, my name is Danny and I'm from Tampa and on behalf of Expert Village I'm going to teach how to use and maintain a rotary grinder. I would be talking about maintenance and when to replace the disc or the grinding wheels. Before you use it you want to make sure that the cord is good. You want to make sure that the gears and all that is good. After you are done using it you just want to blow it it off, wipe it off. Get whatever dust might be inside here. Just if you keep it clean and don't abuse it it should last you a really long time. Knowing when to change your grinding wheels usually when the wheel gets down about here or you can not grind anymore or if you are using the cutting wheel and you can not cut anymore for the application or whatever you are cutting. If is starts hitting the top of this you usually want to change it out and just make sure you change this out frequently, don't get them to short. The flat disc these usually lose all the grit and you just replace these."
