Using the Abaco All - in - One A - Frame is a breeze. First, place your stone slabs on the A - Frame. Adjust the ratchet securing bars according to the size and number of the slabs to keep them stable. You can move the A - Frame around easily with the two swivel casters. When it's time to relocate the A - Frame, use the forklift slots on all base sides to lift and move it. If you want to change it from a transport device to a storage one, simply use the detachable mounting pins. As for maintenance, regularly check the ratchet securing bars for proper adjustment and the rubber strips for any signs of wear. Make sure the swivel casters roll smoothly. Avoid overloading the A - Frame to prevent damage. Also, keep it in a dry place when not in use to avoid rusting.
