Using the Klein D502 - 6 pump pliers is easy. First, use the Quick - Adjust Rivet to set the jaw position with one hand according to your task. Then, place the object you want to grip between the jaws and apply pressure. The wide range of jaw positions allows you to handle different sizes of objects. When using, make sure to apply pressure evenly to avoid slipping. As for maintenance, after each use, wipe the pliers clean with a dry cloth to remove dirt and debris. Store them in a dry place to prevent rusting. Also, check the jaws regularly for any signs of wear. If you notice excessive wear, it might be time to replace the pliers.
