When changing abrasives on an angle grinder, what is recommended?

Unplugging the angle grinder while changing abrasives is recommended for ensuring safety. This practice eliminates the risk of accidental start-up during the abrasive change, which could lead to serious injuries. When the equipment is disconnected from the power source, the operator can safely and easily make the necessary adjustments or changes to the abrasive without worrying about unexpected movement or power activation.

While wearing gloves can protect hands, it does not address the immediate risks associated with an electrically powered tool. Holding the grinder with one hand also poses significant safety risks, as both hands should be used for better control and stability during operation. Changing abrasives while the grinder is on low speed is not safe, as it still poses the risk of the tool unexpectedly turning on and could lead to potential accidents. Thus, unplugging the grinder is the most effective safety measure.
