Using the DeWalt DCF801F2 impact driver is easy. First, insert a charged battery into the tool. You can choose the right mode on the 3 - mode switch according to your job. The Precision Drive™ mode is great for tasks that need high accuracy. When using it, hold the tool firmly and place the bit on the fastener. Then start the driver. Remember to wear safety goggles to protect your eyes. For maintenance, keep the tool clean after each use. Wipe off any dirt or debris. Store the batteries in a cool, dry place. If the bit gets dull, replace it with a new one. And don't forget to charge the batteries regularly to keep them in good condition.
