Please read this manual thoroughly before installation and use to ensure safe and correct application of the product.

4. Setup & Installation

The installation process is designed to be straightforward and can be completed with a screwdriver. The front crossbar is intentionally longer than the rear to accommodate the vehicle's dimensions.

Installation Steps:

1. Open the End Cap Cover: Use the provided key to unlock and open the end cap cover on each cross bar.
2. Remove Rubber Strips: Carefully take out the rubber strips located inside the cross bar channel.
3. Loosen Preassembled Bolts: Using the Allen wrench, loosen the preassembled bolts on the cross bar. Do not remove the bolts completely; ensure they remain connected to the bracket.
4. Place Bracket into Grooved Side Rail: Position the bracket into the grooved side rail of your vehicle's roof. Ensure the outer bolt is loosened enough to allow the bracket to slide into the rail without extending out of the bottom nut.
5. Tighten the Bolts: Once the bracket is correctly positioned, tighten the bolts using the Allen wrench. Note: Do not use an electric drill to avoid cross-threading.
6. Check All Bases: After tightening, ensure all four bases are securely fastened and tight.
7. Replace Rubber Strips and Close End Cap: Place the rubber strips back into the cross bar channel and close the end cap cover, locking it for security.

6. Maintenance

To ensure the longevity and safe operation of your HmmtyRack Roof Rack Cross Bars, regular maintenance is recommended:

• Regular Tightness Checks: Periodically check all mounting bolts and connections to ensure they remain tight. Loose components can lead to instability and potential damage.
• Cleaning: Clean the cross bars with mild soap and water. Avoid abrasive cleaners or solvents that could damage the finish.
• Inspection: Inspect the cross bars for any signs of wear, damage, or corrosion, especially after long trips or heavy use. Replace any damaged parts immediately.

7. Troubleshooting

If you encounter any issues with your roof rack, consider the following:

• Loose Cross Bars: If the cross bars feel loose, re-tighten all mounting bolts as per the installation instructions.
• Excessive Wind Noise: Ensure the aerodynamic profile is correctly oriented (round head facing front, pointy head facing rear). Check that all components are securely fastened.
• Difficulty Installing: Refer to the detailed installation video and ensure you are using the correct front and rear bars for their respective positions.
