What would be the 1st thing you check if odor come from electrical tool?

If an odor comes from an electrical tool, the first thing I would check is the tool's power source and cord for any signs of damage, such as fraying or exposed wires. Next, I would inspect the tool itself for any visible signs of overheating, burnt components, or melted plastic. If everything appears intact but the odor persists, I would stop using the tool immediately and consult the manufacturer's guidelines or a professional for further assessment. Safety is the priority, so I would not attempt to troubleshoot it further without proper expertise.
