Using the DeWalt DCG460B grinder is straightforward. First, make sure to attach the side handle for better control. Select the appropriate guard based on your grinding task - the 7 - inch or 9 - inch ones. Plug in the battery (not included as it's a bare tool) and you're ready to start. When you turn it on, hold it firmly. If you feel a kickback or the tool starts to stall, don't panic. The Kickback Brake and E - CLUTCH System are there to protect you and stop the tool safely. After use, turn off the grinder and remove the battery. Keep the grinder clean by using a dry cloth to wipe off any dust. Periodically check the brushes (even though it's a brushless motor, it's good to check the general condition). Store it in a dry place, away from moisture. And always make sure to use the No - Volt switch to prevent unexpected startups when power is restored.
