The following are Important Safeguards / Precautions that are recommended by most appliance manufacturers. 

Important Safeguards (Safety First (1st):  

To reduce the risk of personal injury or property damage, basic safety precautions should always be followed, including the following: 

1. Always check the exhaust pipe before use. Hold cover up to light and look through exhaust pipe to be certain it is clear. 
2. Do not full pressure cooker over 2/3 full. For soup, rice and dried vegetables – which expand during cooking , do not fill cooker over 1/2 full. 
3. Do not pressure cook applesauce, cranberries, rhubarb, pcarl barley, oatmeal or other cereal, split peas, soup mixes containing dried vegetables of foods such as noodles, macaroni or spaghetti. These foods tend to foam, froth and sputter and may block the exhaust pipe. 
4. Pressure Cookers under pressure. Improper use may result in scalding injury. Make certain pressure cooker is properly closed before operating. Cover handle must be directly above the body handle. 
5. Do not place the pressure cooker or attempt to pressure cooker in a heated oven. 
6. Extreme caution must be used when moving a pressure cooker containing hot liquids. Do not touch hot surface. Use handles or ear handle. 
7. Do not open pressure cooker until internal pressure has been completely reduced, pressure indicating valve has dropped and no steam escapes when the pressure limiting valve is removed. 
8. Caution to ensure safe operation and satisfactory performance, replace the sealing ring sooner if it becomes hard or deformed. 
9. Close supervision is necessary when the pressure cooker is used near children. It is not recommended that children use the pressure cooker. 
10. Do not use pressure cooker for other than intended use. 
11. D o not use the pressure cooker for pressure frying with oil. 
12. Use appropriate heat source(s) according to the instructions for use. 
13. After cooking meat with a skin (e.g ox tongue) which may swell under the effect of pressure, do not prick the meat while the skin is swollen; you might be scalded. 
14. When cooking doughy food, gently shake the cooker before opening the lid to avoid food ejection. 
15. Before each use, check that the valves are not obstructed. 
16. Do not tamper with any of the safety systems beyond the maintenance instructions specified in the instructions for use. 
17. Only use manufacturer’s spare parts in accordance with the relevant model. In particular, use a body and a lid from the same manufacturer indicated as being compatible. 

Additional Precautions: ATTENTION – 

• Do not open the cover forcibly when the indicating valve has not dropped. 
• In case the exhaust pipe was blocked during the cooking process, the pressure must be reduced by forced cooling, then open the cover and clear the steam escaping hole, it can be used again. 
• If the cooker is not in use for a long time, the pushing plate must be checked before putting into use. 
• In order to ensure safety, when the fusible plate breaks, it must not be replaced by other metal plate. 
• While the operation of cooking, do not take out the pressure limiting valve; do not put any weight on it or use others instead. 
• In order to ensure safety, never use any metal tensile ring to increase sealing. 
• Do not use air escaping method to lower the pressure, when soup or porridge is cooked. 
• When in operation, avoid hitting the cooker to ensure steam leakage does not occur due to the deformation of cooker body and cover.
