Steps to use the concrete mixer:Place the portable concrete mixer on a flat, level surface. Make sure that the surface is strong enough to support the weight of the mixer and the concrete mix. 2. Connect the power cord to an appropriate power source and turn on the switch. 3. Fill the drum with water and add the required amount of concrete mix into it. Make sure that you do not overfill it as this can cause problems with mixing and pouring. 4. Start up the motor and allow it to run for a few minutes before turning off the switch again. This will help to ensure that all of the ingredients are mixed properly before you start pouring your concrete mix. 5. Once everything is mixed, turn on the switch again and begin pouring your concrete mix into whatever form or shape you need it in. Be sure to use safety equipment such as gloves, goggles, and a dust mask when working with cement-based materials like concrete mix.
