Using the Automatic Abaco Stone Crab Lifter is easy. First, check if the stone slab's thickness is between ⁹⁄₁₆' (15 mm) and 1 ¹⁵⁄₁₆' (50 mm). Then, position the lifter over the slab and use the clamp plates to secure it. The rubber pads on the plates will protect the slab's surface. Once clamped, use the swivel hook and steel cable to lift and move the slab. When using, always make sure the lifter is properly attached to avoid any accidents. After use, clean the lifter and store it in a dry place. Regularly check the rubber pads for wear and tear, and replace them if necessary.
