4. Setup

1. Unpack: Carefully remove all components from the packaging and ensure all listed items in Section 2 are present.
2. Initial Charge: Before first use, fully charge the vacuum sealer using the provided Type-C charging cord. Connect the cord to the charging port on the device and a suitable USB power source. The digital display will show the charging progress.
3. Prepare Jars: Ensure your Mason jars are clean and dry, especially the rim where the lid will sit.
4. Select Sealer Size: Determine if you are using a regular or wide mouth Mason jar. The main unit is for wide mouth jars. If using a regular mouth jar, attach the standard mouth seal converter by twisting it onto the main unit until securely in place.

5. Operating Instructions

Follow these steps to vacuum seal your Mason jars:

1. Place Lid: Put the flat metal Mason jar lid on top of the jar. Ensure it is centered and flat.
2. Position Sealer: Place the electric vacuum sealer (with the correct size adapter if needed) directly over the lid. Press it down firmly, ensuring it is smooth and centered on the jar lid.
3. Start Sealing: Click the power button on the top of the sealer. The device will begin to pump air out of the jar. The digital display may show a countdown or progress.
4. Wait for Completion: Allow approximately 20 seconds or more for the vacuum sealing process to complete. The device is designed to automatically shut off once a sufficient vacuum is achieved.
5. Stop (Optional): If you need to stop the process manually before it completes, click the power button once again.
6. Remove Sealer: Once the sealing process is complete, carefully remove the electric Mason jar sealer from the jar.
7. Secure Jar: Cover the sealed jar with a split-type Mason jar band (not included with sealer, but typically used with Mason jars) to secure the lid for storage.

6. Important Considerations

• When filling jars with soft or liquid food, avoid overfilling. The less air in the bottle, the shorter the sealing time and the more effective the seal. Leave a space of 1/4 to 1/2 inch from the rim.
• Always ensure the mouth of the Mason jar is dry and clean before attempting to seal. Moisture or debris can compromise the seal.

7. Maintenance and Care

• Cleaning: Wipe the exterior of the vacuum sealer with a soft, damp cloth. Do not immerse the device in water or any other liquid. Ensure the sealing rings are clean and free of food debris for optimal performance.
• Storage: Store the vacuum sealer in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: To prolong battery life, avoid fully discharging the device frequently. Recharge it when the power indicator shows low battery.

8. Troubleshooting

• Device Not Turning On: Ensure the device is charged. Connect it to the Type-C charging cord and allow it to charge for at least 30 minutes before attempting to use it.
• Poor Seal / No Vacuum:
  • Check if the Mason jar rim is clean and dry.
  • Ensure the Mason jar lid is properly centered and flat.
  • Verify that the vacuum sealer is pressed down firmly and evenly on the lid.
  • Confirm the correct size adapter is used for the jar (regular or wide mouth).
  • Inspect the sealing rings on the device for any damage or debris. Clean if necessary.
• Device Stops Prematurely: This may indicate a successful seal has been achieved, or the battery is low. Check the seal. If no seal, recharge the device.
