What should always be checked before using power tools?

Before using power tools, checking the grounding is crucial for ensuring safety. Proper grounding helps prevent electric shock by providing a pathway for electrical current to divert safely in the event of a fault. This is particularly important for power tools, which are often used in various environments that may involve moisture or other conductive materials.

When a tool is properly grounded, it reduces the risk of electrical faults that could lead to severe accidents or injuries. Any break in the grounding system or issues related to the plug or wiring can expose the user to dangerous electrical currents. Thus, confirming that all grounding connections are intact and functional allows for a safer working environment, minimizing the risk of potential hazards while operating power tools.
