Using the DeWalt DCG418B grinder is a breeze. First, make sure you've attached the appropriate guard for your grinding wheel size, either the 4 - 1/2 in. or 6 in. Type 27 guard. Then, connect your charged battery (sold separately) to the grinder. Hold the side handle firmly for better control and switch on the grinder. You're ready to start grinding at the impressive 9000 rpm no - load speed. When you're done, release the trigger, and the brake will engage, stopping the wheel in just 1.5 seconds. As for maintenance, keep the grinder clean after each use. Wipe off any dust or debris from the body and the wheel. Check the flanges regularly to ensure they're tightened properly. Also, store the grinder in a dry place to prevent any damage. Remember, the battery and charger are sold separately, so take good care of them too. Always follow safety guidelines and wear appropriate protective gear when using the grinder.
