Using your Milwaukee 2903 - 20 drill is a breeze. First, make sure the battery is fully charged and properly inserted. Attach the side handle for better control, especially when applying more force. Select the appropriate drill bit for your task and insert it into the all - metal chuck. You can use the mechanical clutch to adjust the torque according to the fasteners you're driving. When drilling, start at a slow speed and gradually increase as needed. The LED light will help you see in dimly lit areas. For safety, always keep an eye on the AutoStop™ feature. If the drill binds up, it will stop automatically to prevent injuries. After use, remove the battery and store it in a cool, dry place. Clean the drill regularly with a dry cloth to remove dust and debris. Check the chuck for any signs of wear and tear, and lubricate the moving parts occasionally to keep the drill in top condition.
