4. Safety Information

Adhere to the following safety guidelines to prevent injury and damage to the product or materials:

  • Always ensure the suction cup and the surface are clean, dry, and free from dust or debris before application.
  • Do not use on curved surfaces, wet surfaces, dirty/dusty areas, rough textures, or porous materials. These surfaces will not allow for a secure vacuum seal.
  • Regularly check the digital pressure display to ensure adequate vacuum is maintained, especially when lifting heavy objects.
  • Avoid sudden movements or excessive force when lifting or moving materials with the suction cups.
  • Ensure batteries are properly charged and inserted before use.
  • Store the tool in its carry case when not in use to protect it from damage.

6. Operating Instructions

Follow these steps for proper operation of the electric suction cup lifter:

  1. Prepare Surface: Ensure the surface of the material to be lifted is clean, dry, and non-porous.
  2. Position Lifter: Place the suction cup lifter firmly onto the desired surface.
  3. Activate Suction: Press and hold the power button for approximately 0.5 seconds. The lifter will begin to create a vacuum.
  4. Monitor Display: Observe the digital display. The vacuum pump will operate until the "Security Value" (typically 68) is reached, indicating a secure grip.
  5. Auto-Replenishment: The device features smart auto-replenishment. If the vacuum pressure drops below 55±5, the pump will automatically reactivate to restore the optimal pressure, ensuring continuous safety.
  6. Lift and Move: Once the secure value is displayed, you can safely lift and move the material.
  7. Release Suction: To release the suction, double-click the power button. This will quickly exhaust the vacuum.
