Coupling To The Tow Vehicle We have utilized a ball hitch coupler that is suitable for the size and weight of the trailer. The load rating of the coupler and the necessary ball size are listed on the trailer tongue. You must provide a hitch and ball for your tow vehicle, where the load rating of the hitch and ball is equal to or greater than that of your trailer. Also, the ball size must be the same as the coupler size. If the hitch ball is too small, too large, is underrated, is loose or is worn, the trailer can come loose from the tow vehicle, and may cause death or serious injury. Your trailer may be equipped with a Hydraulic Surge Brake Actuator. Surge braking is accomplished with an actuator and hydraulic brake assemblies. The "surge" or "push" of the trailer toward the tow vehicle during deceleration automatically synchronizes these trailer brakes with the tow vehicle brakes. As the trailer pushes against the vehicle, the actuator telescopes together and applies force to its master cylinder, supplying hydraulic pressure to the trailer's brakes. For more information, refer to the Surge Brake Actuator manual provided with your trailer. Direct questions regarding surge brake troubleshooting to the hydraulic brake manufacturer. 57 THE TOW VEHICLE, HITCH AND BALL MUST HAVE A RATED TOWING CAPACITY EQUAL TO OR GREATER THAN THE TRAILER Gross Vehicle Weight Rating (GVWR). I T IS ESSENTIAL THAT THE HITCH BALL BE OF THE SAME SIZE AS THE COUPLER. The ball size and load rating (capacity) are marked on the ball; hitch capacity is marked on the hitch. 4.3.1.1 Before Coupling The Trailer To The Tow Vehicle Be sure the size and rating of hitch ball match the size and rating of the coupler. Hitch balls and couplers are marked with their size and rating. ! WARNING Coupler-to-hitch mismatch can result in uncoupling, leading to death or serious injury. Be sure the LOAD RATING of the hitch ball is equal or greater than the load rating of the coupler. Be sure the SIZE of the hitch ball matches the size of the coupler. �� Wipe the hitch ball clean and inspect it visually and by feel for flat spots, cracks and pits.
