Using the DeWalt DCD1623B magnetic drill press is a breeze. First, make sure the drill is securely attached to the metal surface using the permanent magnet base. You don't need to worry about electrical charge for the magnet. Then, select the appropriate chuck for your drill bit - you can easily switch between the 3/4'' Weldon Shank and 1/2'' keyed chuck without using any tools. Next, adjust the speed according to your job requirements. With 10 speed settings, you can find the right one for different applications. When you start drilling, the on - board LED will help you see the area clearly. If the drill senses rotation, the E - Clutch will turn off to keep you safe. Remember to use the fluid reservoir with tube to keep the drill bit cool and lubricated. After use, clean the drill and store it in a dry place. Regularly check the chuck for tightness and the battery for proper charge. This will ensure your drill lasts a long time and performs at its best.
