Using the Aardwolf 30 Automatic Slab Lifter is easy. First, attach it to your forklift properly. Then, position the lifter over the slab you want to lift. As you start to lift, the clamping mechanism will engage and grip the slab. Once you've moved the slab to its destination, lower it to the ground. The spring - loaded latch will automatically release the lifter. When using this lifter, always make sure the slab is within the grip range of 0 - 1.2 inches. Don't exceed the working load limit of 2646 lbs. For maintenance, keep the lifter clean and check the clamping parts regularly for any signs of wear. If you notice any problems, get it repaired immediately. Store it in a dry place when not in use to prevent rust.
