Using your CURT Switch Ball trailer ball set is a breeze. First, select the ball size that matches your trailer's coupler. To change the ball head, simply twist it off the shank and twist on the new one. There's no need for any tools, coins, or pins. When towing, make sure the ball is securely attached and the coupler is properly latched onto the ball. Always double - check the weight capacity of the ball you're using to ensure it can handle the load of your trailer. For maintenance, regularly inspect the balls and shank for any signs of wear, like scratches or dents. Clean the balls and shank with a mild soap and water solution, and dry them thoroughly. The nickel - chrome finish helps protect against rust, but if you notice any signs of corrosion, you can use a metal polish to keep it in good condition. Keep the zinc - plated hex nut and helical lock washer tight to maintain a secure connection. And remember, this set comes with a limited lifetime warranty, so if you have any issues, reach out to the manufacturer.
