I have had my angle grinder for quite some time and while using it today I noticed that the body of the tool was becoming quite hot. I turned it off and unplugged it as this has never happened before and I was quite concerned. Can someone please tell me what might have happened to cause this and how I can go about fixing it?

Makita GA4030K: Angle grinder won't turn on after I dropped it.

Sat, 13 Jun 2020 14:45:09 -0700

I was using my angle grinder to work on a small project the other evening when I was startled and dropped the grinder off of my work bench. Now, when I try to use it, the grinder won’t turn on at all. I tried plugging it into several different outlets throughout my house and that doesn't seem to be the problem so I think it must be the grinder itself. Is there any way to fix this?
