Using this outdoor garden smoker BBQ is easy. First, place the charcoal on the adjustable - height charcoal grid. You can adjust the height of the grid using the crank mechanism to control the heat intensity. Open or close the four adjustable air flaps to manage the airflow and temperature inside the smoker. Put your food on the warming rack to keep it warm while other items are cooking. Place your tools and extra ingredients on the side shelf. When using, always keep the smoker on a flat and stable surface. Make sure there is proper ventilation in the area. After each use, let the smoker cool down completely. Clean the charcoal grid and the interior with a brush. You can also wipe the side shelf and the warming rack with a damp cloth. Regularly check the wheels for smooth movement and the adjustable parts for any signs of wear.
