When using any power tools, what is the best practice?

Being familiar with all switches and controls is essential when using power tools because it ensures that the user understands how the tool operates and can effectively manage its functions. By knowing how to control different aspects of the tool, including starting, stopping, and adjusting settings, the user can increase safety, improve efficiency, and reduce the likelihood of accidents.

Understanding all the controls also allows the user to troubleshoot in case of malfunction and make necessary adjustments while operating the tool. This comprehensive knowledge contributes to safer practices, as users can react appropriately in emergencies and operate the tools more skillfully.

Other choices, like being familiar only with the main switch or relying solely on supervision, do not promote enough understanding or self-sufficiency. Trying to operate tools without reading the instructions is particularly risky, as it may lead to misuse and increase the chances of injury.
