4.1 Tháo dỡ
Carefully remove all components from the packaging. Inspect for any damage. Retain packaging for storage or return if necessary.
4.2 Vệ sinh ban đầu
- Wash the pressure cooker body, lid, and all removable parts (rubber ring, pressure regulator, etc.) with warm, soapy water.
- Rửa sạch và lau khô hoàn toàn.
- Ensure the vent filter and safety valves are clear of any debris. A special cleaning needle is provided for this purpose.

5. Hướng dẫn vận hành
5.1 General Pressure Cooking
- Add food and liquid to the pressure cooker. Do not fill more than 2/3 full for most foods, and no more than 1/2 full for foods that expand (e.g., beans, grains).
- Place the lid on the pressure cooker, aligning the arrows on the lid and body.
- Rotate the lid handles until they lock securely into place. The safety lock should engage.
- Place the pressure cooker on a suitable heat source (gas, electric, induction, ceramic).
- Turn the heat to high. The safety valves will rise as pressure builds.
- Once the pressure regulator begins to hiss and jiggle, reduce heat to maintain a steady, gentle hiss. This indicates the desired pressure level (approximately 12.8 PSI, providing 240-250°F).
- Nấu theo thời gian khuyến nghị.
- After cooking, turn off the heat. Allow the pressure to release naturally until both red safety valves drop down. Do not force cool the canner.
- Once depressurized, unlock and carefully remove the lid, tilting it away from you to avoid steam burns.

5.2 Đóng hộp áp suất
The BUFFALO Pressure Cooker is suitable for pressure canning. Pressure canning is the only safe method for preserving low-acid foods like vegetables, meats, poultry, and seafood. The pressure regulator maintains the necessary pressure for safe canning without requiring a separate pressure gauge.
- Prepare your food and jars according to a tested canning recipe. Ensure jars are clean and free from defects.
- Place a canning rack at the bottom of the pressure cooker.
- Add 2 to 3 inches of warm water to the pressure cooker. For best results and to prevent mineral deposits on jars, add a splash of white vinegar to the water.
- Carefully place filled jars onto the rack, ensuring they do not touch each other or the sides of the canner. You may stack jars if using a second rack, ensuring proper water circulation.
- Secure the lid as described in Section 5.1.
- Turn heat to high. Allow steam to vent steadily from the pressure regulator for 10 minutes before placing the weight on the regulator. This ensures all air is exhausted from the canner.
- Place the pressure regulator weight onto the vent pipe.
- Continue heating until the pressure regulator begins to hiss and jiggle. Reduce heat to maintain a steady, gentle hiss.
- Begin timing the processing according to your recipe. For recommended processing times, refer to the USDA Complete Guide to Home Canning.
- After processing, turn off the heat. Allow the pressure to release naturally until both red safety valves drop down. Do not try to cool the canner rapidly.
- Once depressurized, unlock and carefully remove the lid.
- Using a jar lifter, carefully remove the hot jars and place them on a towel or cooling rack, ensuring they are not touching. Allow jars to cool for 12-24 hours without disturbing them.
- After cooling, check jar seals. A properly sealed lid will be concave (curved downwards) and will not spring up when pressed. You can also tap the lid; a clear, high-pitched sound indicates a good seal.
- Label jars with contents and production date, then store in a cool, dark place.

6. Chăm sóc và bảo dưỡng
6.1 Vệ sinh
- Always allow the pressure cooker to cool completely before cleaning.
- The stainless steel body and lid are dishwasher safe. For hand washing, use warm, soapy water and a non-abrasive sponge.
- Remove the rubber ring from the lid and wash it separately. Ensure it is clean and flexible.
- Clean the pressure regulator and safety valves, ensuring no food particles obstruct them. Use the provided cleaning needle for small openings.
- Dry all parts thoroughly before storage to prevent water spots or corrosion.
6.2 Lưu trữ
Store the pressure cooker in a dry place. To prolong the life of the rubber ring, it is recommended to store the lid upside down on the pot, allowing air circulation and preventing the ring from compressing permanently.
6.3 Linh kiện thay thế
Periodically inspect the rubber ring and safety valves for wear and tear. Replace these parts if they show signs of cracking, hardening, or damage to ensure continued safe operation. Contact BUFFALO customer service or authorized dealers for genuine replacement parts.
