Using the Aardwolf Slab Lifter is easy. First, choose the right model according to the thickness of the slab you want to lift. Place the wide jaw of the lifter on the slab and let the auto - lock mechanism do its job to grip the slab securely. When you're done, the auto - unlock feature will help you release the slab. Remember to check the working load limit before use. Don't try to lift a slab that weighs more than the specified limit. Keep the lifter clean after each use. Wipe off any dust or debris. If you notice any signs of wear and tear, such as loose parts or a damaged jaw, get it repaired or replaced right away. By following these steps, you can ensure the long - term performance of your Aardwolf Slab Lifter.
