What if the food is not completely done after the recommended cooking time?
Simply bring the cooker back up to pressure and cook the food a minute or two longer.
Can I use my stainless steel pressure cooker on all types of ranges?
Your pressure cooker will work on gas, electric coil and ceramic glass (smoothtop) ranges. In addition, stainless steel
pressure cookers will work on induction ranges.
When cooking first begins, is it normal for steam to escape and moisture to form on the cover and between the
handles?
It is normal for steam to escape and a slight amount of moisture leakage to form on the cover and between the handles
when cooking first begins. If leakage continues, the cover handle may not be properly aligned with the body handle
and, therefore, the cover lock cannot engage.
Is it normal for the air vent/cover lock to rise up partially and drop back down when cooking first begins?
It is possible that the air vent/cover lock will move up and down slightly when cooking first begins. Do not be
concerned. The air vent/cover lock will remain in the up position once the cooker has sealed. However, if the air
vent/cover lock continues to move up and down or rises partially, tap it lightly with the tip of a knife. If it does not
rise once you have tapped it, the following may be occurring:
1. The burner is not hot enough.
2. The cooker is not fully closed (see page 4).
3. There is insufficient liquid to form steam.
4. The gasket for the air vent/cover lock needs to be replaced (see page 6).
