Using the DeWalt DWACPRIR Impact Connect Copper Tubing Cutter is a breeze. First, attach the cutter to your compatible impact driver using the included brace bracket. Then, select the appropriate cutting wheel (1/2 - inch or 3/4 - inch) for your copper pipe size. Simply position the cutter around the pipe and turn on the impact driver to start cutting. When you need to switch to driving screws, just use the quick - change brace system to swap functions quickly. Remember to always wear safety goggles when operating this tool. After use, clean the cutter with a dry cloth to remove any debris. Store it in a dry place to prevent rusting and damage. If you notice any signs of wear on the cutting wheels, replace them promptly to ensure efficient cutting performance.
