6. Setup
Before operating the vacuum pump, ensure your vacuum storage bag is ready:
- Place your items (clothing, blankets, etc.) neatly inside the vacuum storage bag.
- Seal the bag completely using its zipper or closure mechanism, leaving only the air valve open.
- Ensure the vacuum bag valve is clean and free from any obstructions. The Movclstud SG-508 is compatible with most vacuum storage bags with a valve diameter of 1.8 inches or less.
7. Operating Instructions
Follow these steps to use your Movclstud SG-508 vacuum pump:
- Place the Movclstud SG-508 pump directly onto the air valve of the vacuum storage bag, ensuring a tight seal.
- Press the power button on the pump to start the vacuuming process. The pump will begin to remove air from the bag.
- Hold the pump firmly in place until the desired level of compression is achieved. The pump can remove air in as little as 10-30 seconds, depending on bag size.
- The pump will automatically shut off after approximately 2 minutes of continuous operation to prevent overheating. If more vacuuming is needed, you can restart it after a brief pause.
- Once the air is removed, remove the pump from the valve and immediately close the valve cap on the storage bag to maintain the vacuum seal.
