What action should not be taken when using a power tool?

Leaving a tool unattended is unsafe because it increases the risk of accidents and injuries. Power tools can pose hazards if not monitored, as they may continue to operate or be used improperly by others if left alone. Ensuring that power tools are always attended while in use contributes significantly to maintaining a safe environment, as it allows for immediate intervention in case of any malfunction or safety issue.

In contrast, maintaining a safe distance from the tool operation, following manufacturer instructions, and using appropriate safety gear are all crucial practices to promote safety while using power tools. These actions help prevent accidents and ensure that the tools are used effectively and safely.
