Using the DeWalt DCF630B is straightforward. First, make sure you're using the right mode for your task. If you need high - speed operation, select Trigger Mode (High Speed). For more delicate work, Trigger Mode (Low Speed) is a good choice. The PushStart Mode is great when you want quick starts, and the Lock - On Mode is useful for continuous operation. Before starting, adjust the nosecone to set the proper screw depth for your project. When using, hold the screwgun firmly with your thumb and forefinger on the wide upper grip flange. The LED light can be very helpful in dark work areas, so make sure it's on. When it comes to maintenance, keep the screwgun clean after each use. Wipe it down with a dry cloth. Avoid using it in extremely wet or dusty conditions. If you plan to use the Tool Connect™ feature, remember to purchase the Chip DCE042 separately. Also, always check the battery (not included) for proper charging before use.
