For safe operation and satisfactory performance, replace the sealing ring gasket if it
becomes hard, deformed, cracked or shows any damage.
Follow these steps to replace the sealing ring Gasket:
1. Remove the old sealing ring gasket and thoroughly wash the cooker cover. Be sure
that the area for the new sealing ring gasket is free of any debris. Dry thoroughly.
2. Place the new sealing ring gasket around inner lip of cooker cover. Make sure that
the new sealing ring gasket lays flat and fits smoothly around the inner lip of the
cooker.
3. With the new sealing ring gasket installed properly, add a thin coat of cooking oil to
the top rim of the cooker body where it contacts the lid gasket.

ManuaL reLease VaLVe

The manual release valve is designed for long life
and, under normal operating conditions, should not
require dismantling. To clean and check operation,
lightly pull up on the lifting ring and rinse under warm
water. If the valve leaks steam during the cooking
cycle, replace manual release valve immediately.
DO NOT attempt to repair manual release valve or
use pressure cooker without the manual release
valve in place.
