Using the DeWalt DCG413H1 small angle grinder is easy. First, make sure the battery is fully charged. You can check the charge status using the 3 - LED fuel gauge on the battery. Insert the battery into the grinder. To start the tool, use the two - stage trigger. This means you need to do two actions to get it going. When using the grinder, be aware of the kickback brake. If there's a pinch, stall, or bind - up, it will activate and stop the wheel quickly to keep you safe. The brake also stops the wheel in 2 seconds or less on average. As for maintenance, keep the grinder clean. After use, wipe it down to remove any dust or debris. Check the battery regularly.

Also, if there's a power outage or unexpected shut - down, you'll need to cycle the ON/OFF trigger switch to restart the tool. And always use the side handle for better control. The kit comes with everything you need, including a charger, a kit bag, and various accessories. Make the most of your DeWalt DCG413H1 grinder by following these simple steps.
