Why is there a burning smell coming from my drill?

Check your drill vents to see if there is anything stuck in them. If there is, clear it out before turning it back on. If not, it's probably your carbon brushes wearing out. Check the vents to see if there are sparks when you turn the drill on. Sparks means you're good, no sparks means the brushes need to be replaced. Check the troubleshooting page for more info: Troubleshooting

"Kevin, as Katie was suggesting could be caused by dirt/dust in drill, if you have access to compressed air and blow gun, blow air through the rear air vent louvers to blow out dust and debris and try drill.
