Setup
Before first use, ensure the appliance is clean and dry. Place the vacuum sealer on a flat, stable surface. Plug the power cord into a standard electrical outlet.
Operating Instructions
Vacuum Sealing Bags:
- Prepare the Bag: Place the food item into a vacuum sealer bag. Ensure there is at least 3 inches of space between the food and the top of the bag to allow for proper sealing.
- Position the Bag: Open the lid of the vacuum sealer. Place the open end of the bag into the vacuum chamber, ensuring it is within the dotted line marking the vacuum bag entrance. Make sure the vacuum extraction port is not covered by the bag.
- Close the Lid: Close the lid and press downward firmly on both ends until two "click" sounds are heard, indicating the lid is securely latched.
- Select Mode and Start:
- For dry foods, press the "DRY" button.
- For moist or delicate foods, press the "WET" button.
- Release and Open: Once the sealing process is complete, press the "OPEN" button to release the locks and open the lid. Carefully remove the sealed bag.

Using "Seal Only" Mode:
This mode is ideal for sealing bags without vacuuming, or for creating custom-sized bags from a roll.
- Place the open end of the bag onto the sealing strip.
- Close the lid and press down firmly until it clicks.
- Press the "SEAL ONLY" button. The machine will heat and seal the bag.
- Once the sealing indicator light turns off, press "OPEN" and remove the sealed bag.
Using the External Vacuum Function:
The external vacuum hose allows you to vacuum seal compatible containers, jars, and wine stoppers.
- Connect one end of the external vacuum hose to the vacuum port on the appliance.
- Connect the other end of the hose to the port on your vacuum-compatible container or accessory.
- Ensure the container lid is securely closed or the wine stopper is properly inserted.
- Press the "EXTERNAL" button (if available, or use the appropriate vacuum button if the machine automatically detects external connection). The machine will begin to vacuum the container.
- Once vacuuming is complete, the machine will stop. Remove the hose from both the appliance and the container.

Maintenance and Cleaning
Regular cleaning and maintenance will ensure the longevity and optimal performance of your KitchenBoss vacuum sealer.
- Always unplug the appliance before cleaning.
- Wipe the exterior of the machine with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Clean the vacuum chamber and sealing strip with a damp cloth after each use, especially if any food residue or moisture is present. Ensure these areas are completely dry before closing the lid or storing.
- The sealing strip may be hot after use; allow it to cool before cleaning.
- The vacuum gasket can be removed for cleaning if necessary. Ensure it is properly reinstalled before next use.
- Store the appliance in a dry place with the lid unlatched to prevent compression of the sealing gasket, which can affect its performance over time.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine does not turn on. | Not plugged in; power outlet issue. | Ensure the power cord is securely plugged into a working electrical outlet. |
| Machine is not vacuuming properly. | Lid not latched; bag not positioned correctly; sealing gasket dirty/damaged. | Ensure the lid is firmly pressed down until two clicks are heard. Reposition the bag so the opening is flat and fully inside the vacuum chamber, not covering the vacuum port. Clean or replace the sealing gasket if it appears dirty or damaged. |
| Bag is not sealing. | Sealing strip dirty/damaged; bag material incompatible; too much moisture. | Clean the sealing strip. Ensure you are using proper vacuum sealer bags. For moist foods, pre-freeze or place a paper towel at the top of the bag to absorb excess moisture. |
| Air leaks into the bag after sealing. | Improper seal; sharp objects in bag; bag puncture. | Inspect the seal for wrinkles or incomplete areas; re-seal if necessary. Ensure no sharp food items are puncturing the bag. Use a new bag if a puncture is suspected. |
