Step 4: New Brushes
Body Grinders, routers, and other tools that run at high loads for a long time wear out their brushes quickest.
Brushes usually don't die suddenly.
At first you'll have to shake or twist the tool to get it to start.
Then maybe you'll have to push the wheel with a stick to get it to start.
Eventually it won't start at all.
Brushes are really easy to check on a good tool.
They're under the little "frankenstein neck bolt" plastic covers. Be careful because sometimes the springs jump and throw stuff away stuff you want.
One of these brushes is obviously messed up, looks likethe spring broke, shorted, and lost its springiness.
Don't buy a new angle grinder that costs less than $15. This one was $17 and it's fabulous. It came with spare brushes.
