Using the Abaco Portable Electric Vacuum Lifter is a breeze. First, make sure the battery is fully charged or you can use the hand - pump mode. Place the soft - rubber suction cup on the surface of the load you want to lift. The suction cup will firmly adhere to the surface thanks to its strong suction. Once attached, you can start moving the load easily. When the battery is low, you'll hear and see the alarm, so stop using it to ensure safety. If the battery runs out, switch to the hand - pump mode. For maintenance, keep the lifter clean and store it in a dry place. Check the battery regularly and replace it when necessary. Also, inspect the suction cup for any damage and replace it if needed.
