Using the Milwaukee M18 ROVER 2368 - 20 light is easy. First, decide how you want to power it. You can either connect it to a 120V AC extension cord for all - day use or use an M18 REDLITHIUM battery. When you're ready to set it up, use the hook, magnet, or keyholes on the base to mount it in the desired location on the jobsite. You can adjust the brightness using the 3 available settings and optimize the light head according to your needs. For storage, fold the protected light heads for compactness. As for maintenance, keep it clean and dry. Since it's IP54 rated, it can handle some dust and water, but don't submerge it. If it takes a hard hit, check for any visible damage. Remember, it has a 5 - year tool warranty and a limited lifetime LED warranty, so if you run into any issues, you're covered.
