Plug the tool into a standard 230V electrical outlet. The Livetool Indicator will illuminate, signifying the tool is connected to power. To turn the tool on, slide the ON/OFF switch to the 'ON' position. To turn it off, slide the switch to the 'OFF' position.

The Ryobi EHT150V features variable speed control, allowing adjustment from 10,000 to 35,000 RPM. Rotate the speed dial to select the appropriate speed for your application and material.
