Using the DeWalt DCD1623GX2 magnetic drill press is a breeze. First, charge the included DCB609G FLEXVOLT batteries using the charger. Attach the drill press to 1/4 - inch or thicker metal using the permanent magnet base. You can choose the appropriate chuck (3/4'' Weldon Shank or 1/2'' keyed chuck) and change it without tools using the Quick - Change Chuck system. Set the speed according to your job requirements from the 10 available speed settings. When drilling, the on - board LED will help you see the area clearly. For tapping, use the forward/reverse control. Remember to keep the drill press clean after use. Check the fluid reservoir regularly and refill it as needed. Also, store the drill press in a dry place to prevent damage. When not using the batteries, store them in a cool and dry environment. If you notice any abnormal noises or issues, stop using the drill press immediately and check for problems.
