4. Setup and Basic Operation
4.1 Initial Setup
- Unpack the vacuum sealer and all accessories.
- Place the machine on a flat, stable, and dry surface.
- Ensure the power cord is securely plugged into a suitable electrical outlet.
4.2 Sealing a Bag
Step 1: Open the Lid. Press the buttons on both sides of the machine to release and open the lid. The lid will unlock and turn up, ready for the next operation.

Figure 4.1: Illustration showing how to press the side buttons to open the vacuum sealer lid.
Step 2: Position the Bag. Place the vacuum bag flat into the vacuum chamber. Ensure the bag opening does not extend beyond the vacuum baffle.

Step 3: Close the Lid. Close and press down firmly on both ends of the lid until you hear two "click" sounds, indicating the lid is properly closed and locked.

Step 4: Select Mode and Seal. Choose the desired vacuum mode (e.g., "Vacuum" for full vacuum and seal, or "Seal" for sealing only). The red light will turn off once the process is complete. Then, open the lid to retrieve your sealed item.

4.3 Using External Vacuum System
The external vacuum system allows you to vacuum seal jars, wine bottles, and other compatible containers. Connect the external vacuum hose to the accessory port on the machine and to the container's vacuum port. Select the appropriate mode for external vacuuming.

5. Food Preservation Guidelines
Vacuum sealing significantly extends the shelf life of various foods by reducing oxidation and preventing moisture loss. The following table provides general guidelines for freshness periods:

Figure 5.1: A table providing suggested freshness periods for various food types (meats, seafood, dried fruits, eggs, coffee, teas, infant formula) under both non-vacuum and vacuum storage conditions, for cold storage (-16~-20°C) and refrigeration (0~8°C).
Note: The actual preservation effect is influenced by the initial freshness of the food, storage temperature, and other environmental factors. These are general suggestions.

Figure 5.2: A visual comparison showing two pieces of meat, one vacuum-sealed and one not, illustrating how vacuum preservation reduces oxidation and maintains taste, while non-vacuum preservation leads to a shorter freshness period and flavor changes.
5.1 Recommended Vacuum Bags
For optimal vacuuming and sealing results, it is recommended to use QIQIAOB professional vacuum bags with a deep airway and textured surface. Bags without texture or with double-sided/rectangular textures may not provide the best seal.

Figure 5.3: A comparison of vacuum bag textures, indicating that bags with a "Round Texture" are recommended for better vacuuming and sealing, while bags with "No Texture," "Double Sided Texture," or "Rectangular Texture" are not ideal.
6. Maintenance and Cleaning
Regular cleaning ensures the longevity and optimal performance of your vacuum sealer.
- Always unplug the appliance before cleaning.
- Open the upper lid to access the vacuum chamber and sealing strip area.
- Wipe down the exterior and interior surfaces, especially the vacuum water tank and sealing foam gaskets, with a damp cloth.
- Do not immerse the machine in water or any other liquid.
- Ensure all parts are completely dry before closing the lid and storing the machine.
