Using your DeWalt DCE6820B powered water tank is easy. First, make sure you have a 20V MAX battery (sold separately) installed. Then, open the large - mouth cap and fill the tank with water. You can easily see the water level through the translucent tank to avoid over - filling. To start the water flow, just flip the switch on the control panel. If you want to use the wireless feature, pair the tank with a compatible tool or remote (sold separately). You can then activate the tank from a distance. When moving the tank around the jobsite, use the two handles for a comfortable grip. You can also store it in a T - Stak or Tough System Rolling Toolbox (sold separately) for better mobility. For maintenance, clean the tank regularly through the wide opening. The mesh strainer helps keep debris out, but you may want to check it occasionally. Also, make sure the 10 - ft braided hose is free of kinks for a steady water flow. If you want to track the tank, attach the DEWALT Tag (sold separately) and use the DEWALT Site Manager app. Remember, this tank is OSHA - compliant when paired with a DEWALT Concrete Cut - Off Saw or Core Drill.
