6. Operating Instructions
6.1. Deflating Vacuum Storage Bags

Image: A six-step visual guide demonstrating the process of compressing a vacuum storage bag: choosing the right bag, sealing, unscrewing the valve cover, aiming the pump, double-clicking to start, and tightening the valve cover.
- Prepare the Bag: Place items neatly inside the vacuum storage bag. Ensure the bag is not overfilled and the zipper seal is completely closed.
- Open the Valve: Unscrew the valve cover on the vacuum storage bag in the direction of the word "OPEN".
- Attach the Pump: Place the deflation port (bottom) of the electric pump directly onto the open valve of the vacuum bag. If the valve diameter is 33mm, use the pump directly. If the valve is 19mm, attach the complimentary deflating port adapter to the pump first.
- Start Deflation: Double-click the pump switch button to turn on the pump and begin suction.
- Monitor: Allow the pump to remove air until the bag is compressed to the desired level.
- Stop and Seal: Single-click the pump switch button to turn off the pump. Immediately tighten the valve cover in the direction of the word "CLOSE" to prevent air from re-entering.
6.2. Inflating Items

Image: A three-step visual guide demonstrating how to inflate items: choosing the correct nozzle, connecting it to the pump's side port, and double-clicking to start inflation.
- Select Nozzle: Choose the appropriate inflatable nozzle from the included accessories that fits the valve of the item you wish to inflate (e.g., swimming ring, air bed, inflatable pillow).
- Attach Nozzle: Insert the selected nozzle firmly into the inflation port (side) of the electric pump.
- Inflate Item: Insert the nozzle into the item's air valve. Double-click the pump switch button to turn on the pump and begin inflation.
- Monitor: Inflate the item to the desired firmness.
- Stop: Single-click the pump switch button to turn off the pump. Remove the nozzle and close the item's air valve.
Note: This pump is designed for low-pressure inflatable items. Do not use for high-pressure items like vehicle tires or sports balls.
