What should an operator do with a power tool that produces excessive smoke?

When a power tool produces excessive smoke, the operator should stop using it and investigate the cause. This is critical because smoke can indicate several serious issues, such as overheating, electrical failure, or internal damage, all of which could lead to further malfunctions or even pose safety hazards, such as fire. Continuing to use the tool, even cautiously, could exacerbate the problem, cause irreparable harm to the tool, or result in injury to the operator. Monitoring the tool for further issues can be inadequate in ensuring safety and functionality, and cleaning the exterior only does not address any underlying mechanical or electrical problems that may be causing the smoke. Therefore, stopping to investigate ensures a thorough diagnosis and helps in making the tool safe for future use.
