NOTES ON SAFETY
The four pressure-releasing devices ensure safety!
1. Pressure Regulator:
According to the cooking requirement, select position I or the steam
setting
2. Pressure Indicator:
It will rise when the pressure is up to 4Kpa. Steam releases from here if the
steam-releasing hole is blocked.
3. Rubber Gasket/Safety window:
If the pressure regulator and the pressure indicator become blocked, the
rubber gasket will tear and be squeezed out from the safety window on the
rim of the lid as a safety measure. STOP cooking if this happens.
4. Push button:
Will only operate if pressure cooker is not under pressure. NEVER try to
override this feature
