/diy/ - Do It Yourself

>>1567055
Brushed tools always get that little arc, especially with changing speeds and start-stop, and you get a tiny bit of electrical smell. But if you’re smelling a real strong burning scent, you may want to check out the brushes and make sure the connections are good and it’s clean. Some of the motors have built in brushes and there isn’t much you can do, so if they’re fucked up you will probably end up burning up some connection and need to send it back for warranty work.
