Using the Milwaukee M12™ ROVER™ flood light is easy. First, insert the M12™ XC4.0 Battery into the light. You can then place it on a flat surface or use the rear - facing magnet to attach it to metal surfaces like car hoods. If you need to hang it, use the integrated keyhole. The 110° pivoting light head allows you to adjust the light direction according to your needs. When you need to charge your phone or other devices, just plug them into the 2.1Amp USB port. For handheld use, hold the overmolded base. Remember to keep the light away from excessive heat and moisture as it's IP54 rated but not completely waterproof. After use, store it in a dry place. If the light gets dirty, wipe it with a clean, dry cloth. The 5 - year tool warranty and limited lifetime LED warranty ensure you can use it worry - free.
