Using the DeWalt DWE402 angle grinder is quite straightforward. First, make sure to attach the two - position side handle for better control. If you need to change the wheel, use the Quick - Change Wheel Release feature to remove it without a wrench. The One - Touch Guard can be rotated 360 degrees in one go to suit your working needs. When you're ready to start, press the paddle switch, but remember to use the safety lock - off to prevent accidental starts. For maintenance, the Dust Ejection System helps keep the tool clean. Check the brushes regularly; when they need replacing, the auto - off feature will shut down the tool to avoid damage. Also, since the side handle has oversized threading, it's durable, but still, handle it gently. Don't forget to use common accessories with the matching wheel flanges. Always follow safety procedures when using this tool, and you'll get great results for a long time.
