Using the Abaco Dual Pump Vacuum Lifter is easy. First, decide whether to use the compressed air in the warehouse or the hand pump to create the vacuum force. Then, place the lifter on the non-porous material, like a stone slab, and let the soft-rubber suction cups do their job. Make sure to keep an eye on the double audio-visual alarm during operation. If it goes off, it means the pressure is low. When moving the material, ensure it's within the work load limit. For storage, its simple and compact design allows for easy placement. As for maintenance, check the suction cups regularly for any signs of wear and tear, and keep the pumps clean.
