Marking and Drilling Holes on the Trailer Tongue: - Measure and mark a point on the trailer tongue 24” from the center of the hitch ball. - Align the ball/plate assembly (3) with the mark and center punch four hole locations. - Drill four holes using the appropriate drill bit for the trailer tongue thickness. 4. Securing the Ball/Plate Assembly: - Position the ball/plate assembly (3) over the drilled holes. - Drive four self-tapping screws (2a) through the plate into the trailer tongue. - Drill the remaining two holes and secure them with screws. ### 2. Hook-Up 1. Lubricating and Attaching Slide Bar: - Lubricate both sway control balls with grease. - Place the socket of the slide bar (6) over the hitch ball (1a) and secure it with a clip (2b). - Extend the sway control assembly and place the other socket over the ball on the trailer. Secure it with another clip (2b). 2. Tension Adjustment: - Loosen the handle (5) until the slide bar can move freely. - Retighten the handle until it stops and returns to its original level position. 3. Preventing Damage: - Slowly back the vehicle into a jackknife position to check for potential contact or bottoming out of the sway control. - If contact is likely, remove the sway control before backing the trailer. ### 3. Adjustment - Perform road tests with the loaded trailer to adjust the tension: - Turn the adjusting bolt (7) in 1/4-turn increments to increase or decrease tension. - For large trailers, a second sway control unit may be necessary. ### 4. Unhooking 1. Turn the on/off handle counterclockwise to release tension. 2. Remove both clips (2b) and detach the sway control. --- ## Maintenance 1. Clean the friction surfaces of the slide bar (6) with a wire brush after the first 1,000 miles and then every 10,000 miles. 2. Never paint or lubricate the slide bar. 3. Inspect all hardware periodically for wear or damage. --- ## Safety Notes 1. Vehicle Stability: - Avoid towing with improper trailer loading. Heavy items should be on the floor in front of the axle. - Maintain tongue weight at 10-15% of the gross trailer weight. 2. Hazardous Conditions: - Reduce sway by turning the handle counterclockwise during wet, icy, or gravel road conditions. 3. Speed Control: - Never speed up if sway occurs. Reduce speed and investigate the cause. --- ## Manufacturer Details - Company: Cequent Performance Products - Contact: (888) 521-0510 - Document Revision: 83660N, 1-15-09, Rev A
