Driving tips 4. Pull the ball mount to make sure it does not come off the hitch receiver. HB8020BC HB8020AA 1) Hitch ball installation point 2) Hooks for safety chains 5. Use only a hitch ball that is appropriate for the ball mount and your trailer. The hitch ball must be securely installed on the ball mount. 6. Connect your trailer to the hitch ball. 7. Connect the trailer and the hitch with safety chains that will hold the trailer's maximum gross weight. The chains should cross under the trailer tongue to prevent the tongue from dropping onto the ground in case it should disconnect from the hitch ball. Allow sufficient slack in the chains taking tight- turn situations into account; however, be careful not to let them drag on the ground. WARNING Do not connect safety chains to improper positions such as those shown in the following picture. - CONTINUED - 8-25
