Using the Abaco EZ - PRO Battery Seam Setter is easy. First, make sure the battery is fully charged. Press the Power button to turn it on. Place the two rectangular suction cups on the edges of the slab tiles you want to join. Press the Vacuum button, and the soft - rubber suction cups will firmly stick to the tiles. Use the Movement button to adjust the position of the tiles until they're perfectly aligned. Once you're satisfied, you can proceed to glue the tiles. When you're done, press the Release button to detach the suction cups from the tiles. As for maintenance, keep the battery charged when not in use. Clean the suction cups regularly with a soft, damp cloth to remove any dust or debris. Store the seam setter in a dry place to prevent damage.
