Using your DeWalt 20V MAX* DCL050 area light is easy. First, make sure the battery is fully charged. You can then turn it on and choose between the two brightness settings according to your needs. If you need to light up a specific area, use the 140 - degree pivoting head to adjust the light direction. You can hang the light using the built - in telescoping and 360° rotating hook from 2 - foot materials. If you want to carry it around, attach a belt hook accessory. When it comes to maintenance, keep the light clean. Wipe the over - molded lens cover gently with a soft cloth. Avoid exposing the light to extreme temperatures or moisture. And don't forget to recharge the battery regularly to ensure it's always ready for use. If you have any problems, contact DeWalt's customer service.
