1)Use the cookware in accordance with the instructions. 2) Never place the stainless steel cooker on direct heat without any water or food inside. This can cause overheating, damage to the base, or discoloration. 3)For the best cooking results, use low to medium heat. High heat can cause the cooker to overheat and affect its longevity. Always adjust the heat as needed during cooking. 4)After cooking, ensure the pressure has been fully released before opening the lid. Never force the lid open, as this may cause injury or damage to the cooker.
