- Place Food: Place the food item inside the vacuum bag.
- Position Bag: Open the lid of the vacuum sealer. Place the open end of the bag into the vacuum chamber, ensuring it lies flat across the sealing strip.
- Close Lid: Press down firmly on both ends of the lid until you hear two "pops," indicating it is securely latched.
- Select Mode:
- Auto Mode: For dry foods like nuts or coffee beans. The machine will automatically vacuum and seal.
- Moist Mode: For juicy items such as seafood or meats. This mode adjusts sealing time for moisture.
- Pulse Mode: For delicate foods like bread or cured meats. Press and hold the "Pulse" button to manually control vacuum pressure, then press "Seal" when desired vacuum is reached.
- Start Process: Press the desired mode button (e.g., "Auto" or "Moist"). The digital display will show a countdown.
- Completion: Once the process is complete, the indicator light will turn off. Press the release buttons on the sides (if applicable) or lift the lid to remove the sealed bag.
- Stop Function: Press the "Stop" button at any time to cancel the current operation.
