Using the Milwaukee M18/M12 Wireless Jobsite Speaker is a breeze. First, if you're using a battery, make sure it's an M18 or M12 Red Lithium Pack and insert it properly. Or you can plug it into an AC power outlet. Then, turn on the speaker and use the Bluetooth function on your smartphone, tablet, or other mobile device to pair with it from up to 100ft away. Once paired, you can start streaming high - definition music. When it comes to volume, you can adjust it to your preference, but remember the max volume is 119db. As for maintenance, since it has IP54 water and dust protection, it can handle some light splashes and dust. But try to avoid exposing it to heavy rain or a very dusty environment for a long time. Also, if it gets dropped, check the impact - resistant side caps and roll cage for any visible damage. The protected 2.1A USB power outlet can be used to charge your small devices, just make sure not to overload it.
