Using your Abaco Aluminum Tug Dolly is a breeze. First, make sure you're on a flat surface. This dolly is great for narrow alleys, so don't worry about tight spaces. When loading, place the slab gently on the dolly, ensuring it's centered for balanced weight distribution. It can hold up to 450kg, but don't overload it. When moving, just grasp the handle and push or pull. The four - solid - wheel design makes it easy to control and reduces the risk of damage to the slabs. Regarding maintenance, keep it clean and dry. After use, check the wheels and the aluminum body for any signs of wear or damage. If there are any issues, get them fixed right away. Also, the gray rubber tires are great for not leaving marks on light - colored floors, but still be careful to avoid rough surfaces that could damage the tires.
