Using the DeWalt DCLE34520G is a breeze. First, make sure the 20V MAX* 2 Ah lithium - ion battery is fully charged. Insert it into the laser tool. You can use the fine - adjustment knob to position the laser exactly where you need it. The magnetic mount is great for attaching the laser to metal surfaces on the jobsite. When using the laser lines and spots, you can turn them on and off individually to save battery life. For high - precision work, remember that it's accurate within 1/8 in. at 30 ft. As for maintenance, keep the laser clean from dust and debris. Store it in the provided TSTAK® case when not in use. If you're not using it for a long time, remove the battery to avoid potential damage. Also, make sure to charge the battery regularly to keep it in good condition. You can use both 20 - Volt max and 12 - Volt max batteries, but check the runtime differences.
