Using the BNR6500 power mixer is easy. First, make sure it's plugged into a 120V, 60Hz power source. Select the appropriate speed using the variable speed adjustment and lock it if needed. Attach the mixing paddle to the chuck. Place the mixer into the material you want to mix, like paint or mortar, and start it up. It will mix from the bottom to the top for a thorough blend. Remember to wear safety goggles and gloves when using the mixer. Don't exceed the recommended material capacity of 24 gallons. After use, unplug the mixer and clean the paddle and chuck. You can use a brush and some water to remove any residue. Store the mixer in a dry place. If you have any issues, refer to the 1-year limited manufacturer warranty.
