Using your Milwaukee 2116-21 USB Rechargeable BEACON Hard Hat Light is a breeze. First, attach the headlamp to your hard hat using the universal hard hat clips. Make sure it's securely fastened. Then, turn it on and choose from the five light output modes according to your needs. For general tasks, the Hybrid Spot/Flood mode with 600-lumens is great. If you need a long - distance view, use the Spot High mode. When you want to be visible from afar, turn on the BEACON™ personal safety light. You can switch between steady and blinking modes. Charging is easy too. Use the micro - USB port to charge the REDLITHIUM™ USB battery. You can also swap it out with an extra battery if you're in a hurry. Check the LED fuel gauge to know the battery level. As for maintenance, keep the headlamp clean and dry. Wipe it with a soft cloth if it gets dirty. Avoid exposing it to extreme temperatures or rough handling. And remember, the light has a limited lifetime warranty, and the battery has a 2 - year warranty, so you're covered for a long time.
