15. Wait until the pressure has totally been released from the Pressure
Regulator Valve and the Pressure Lift Pin has dropped.
CAUTION: The Pressure Lift Pin will be UP when the Pressure
Cooker is under pressure. When the pressure is released, the Pressure
Lift Pin will drop DOWN. NEVER attempt to open the Lid while the
Pressure Lift Pin is in the UP position.
CAUTION: Escaping steam can scald you, and the Lid will be hot.
Release steam where it will not cause damage to cabinets or kitchen
equipment/accessories.
16. To remove the Pressure Cooker Lid, pressure must be released
before opening. When pressure is completely reduced, slide the
Lid Lock Button towards you, twist the Lid counter-clockwise until
the Lid can be removed easily. Always tilt the Lid away from you to
avoid the steam.
CAUTION: Never force the Pressure Cooker Lid open. The Safety
Lock will not release if any steam pressure remains in the Pressure
Cooker. If the Lid is difficult to remove, allow the Pressure Cooker
more time to cool down until the pressure is fully reduced.
CAUTION: Proper care must be taken with hot cookware. Be careful
not to come in contact with hot Pressure Cooker Pan, Lid and
accessories. Use protective mitts or gloves to move hot Pan. When
opening a hot Pan, use special caution. Escaping steam is hot and can
cause burns.
