This grill gets very hot in use. Do not move it during operation. Always use heat-resistant gloves when refilling charcoal. As this product contains components made of steel and/or cast iron, the surface will age and develop surface rust over time, as soon as it is exposed to natural weather elements. This is to expect and does not cause any device errors. For safety reasons, it is recommended to check this product for signs of fatigue and damage before each use. Make sure you replace any devices that have reached the end of their natural life.
