1, before use, check whether the air hole of the valve seat in the center of the pot cover is clear, whether the anti-blocking cover is clean, whether the safety plug is intact and whether the self-locking valve is flexible. The seal can only be stamped after the blockage is eliminated.

2. The food put into the pot should not be too full, and it should not exceed 2/3 of the total volume of the pot, otherwise the safety plug of the exhaust hole will be easily blocked, causing an explosion.

3. Close the lid, make sure it is screwed into the groove, turn the upper handle clockwise, align the symbols on the lid surface with the symbols on the upper and lower handles of the pot, and the upper and lower handles are completely coincident.

4. In the cooking process, if the pressure limiting valve makes a loud hiss, it is necessary to immediately turn down the flame to cool down.

5. Don't add other heavy objects to the pressure limiting valve to avoid cover collapse accident.

6. In the cooking process, if the safety plug is found to be exhausted, the fusible piece should be updated in time.

7. Don't cook porridge, beans and sparerib soup in a pressure cooker, because the foam generated by high pressure in the cooker may block the vent hole and pressure limiting valve, leading to an explosion.
