Do not damage the sealing ring or replace it with other rubber rings, and do not use tension rings to replace the seal. At the same time, do not use sharp instruments to clean the inside and outside of the pot to avoid scratching the coating of the body or causing deformation of the body, which will affect the performance of the electric pressure cooker.

When in use, if an obstacle occurs after repeatedly selecting functions, please be sure to stop using it and send it to the maintenance department to find a professional for repair in time.
