Reducing Pressure
WARNING: Steam escaping from the vent pipe can scald or burn you and the pressure regulator weight may
be hot. Protect your hand with a pot holder or mitt.
When cooking is completed and heat is off, reduce pressure as follows:
• After canning in glass jars, turn heat off and permit cooker to cool gradually until the pressure dial gauge
drops to zero. Remove the pressure regulator weight with a hot pad. Wait 2 minutes, and then unfasten
cover by turning wing nuts counter-clockwise until the bolts are able to be flipped down. Remove the
cover, raising farthest edge first to protect face and arms from steam.
• After canning in tin cans, turn heat off and release pressure as quickly as possible by removing the
pressure regulator weight with a hot pad. Wait 2 minutes; unfasten cover by turning wing nuts counter-
clockwise until the bolt is able to be flipped down. Remove the cover, raising farthest edge first to
protect face and arms from steam.
• DO NOT put cold cloths or water on the cooker to hasten cooling. Forced cooling may result in food
spoilage and may crack the aluminum.
• DO NOT move the pressure cooker until the pressure is completely reduced and pressure dial gauge
reads ZERO.
• DO NOT loosen the wing nuts until the pressure dial gauge reads zero, and the remaining pressure has
been exhausted by carefully removing the pressure regulator weight and you have waited 2 minutes
• When the pressure regulator weight is left on a long time after the pressure has been reduced to zero, a
vacuum may form inside the cooker making the cover difficult to remove. To avoid a vacuum, you must
remove the pressure regulator weight from the vent pipe as soon as the pressure dial gauge indicator
reaches ZERO p.s.i. and then remove the cover after waiting 2 minutes. The longer you wait without
removing the pressure regulator weight, the more vacuum will form, pulling the cover tighter and tighter
to the bottom.
• Another reason that a cover sticks to the bottom is that the metal-to-metal seal has been permitted to
build up a coating of lubrication or the seal was not lubricated at all. Please refer to page 10 for cleaning
metal-to-metal seal.
Removing a “Stuck” Cover (due to vacuum)
• In the event that a vacuum forms, use a large standard screwdriver to pry the cover loose. Place the end
of the screwdriver at an angle between the cover and bottom near a wing nut assembly. Do not go
straight in with the screwdriver or you will damage the metal-to-metal seal. Gently pry upward using the
screwdriver as a lever. Continue to pry upward at each wing nut assembly area uniformly so that the
cover is raised evenly. In most cases, the cover should come off rather quickly. If you need further
assistance, please call factory.
