2. Safety Information

• Always adhere to the maximum load capacity of 75 kg for these roof bars. Note that the actual load capacity is also limited by your vehicle's specific roof load capacity, as stated in your car's owner's manual.
• Ensure all components are securely fastened before driving. Regularly check the tightness of all fixings, especially after the first few kilometers and periodically during long journeys.
• Distribute the load evenly across the roof bars. Secure all cargo properly to prevent shifting during transit.
• Driving with roof bars and cargo can affect vehicle handling, braking, and fuel consumption. Adjust your driving style accordingly, especially in windy conditions or when cornering.
• Be aware of the increased vehicle height when carrying cargo on the roof, particularly when entering garages, car washes, or low-clearance areas.
• Never exceed legal speed limits or the recommended speed for driving with roof bars.

5. Operating Instructions

Once installed, your La Prealpina LP49 roof bars are ready for use. Always ensure that any cargo placed on the bars is within the specified weight limit and is securely fastened using appropriate straps or cargo carriers. Distribute the weight as evenly as possible to maintain vehicle stability.

• Loading: Place cargo carefully on the PVC-coated loading surface. Avoid dragging heavy items across the bars to prevent scratches.
• Securing Cargo: Use high-quality tie-down straps, nets, or specialized carriers (e.g., bike racks, ski carriers) to secure your load. Ensure there is no movement or play in the cargo before driving.
• Aerodynamics: Consider the aerodynamic impact of your cargo. Large or irregularly shaped items can significantly increase wind resistance and noise.

6. Maintenance

Regular maintenance will ensure the longevity and safe operation of your roof bars.

• Cleaning: Clean the aluminum bars and PVC surfaces with mild soap and water. Avoid abrasive cleaners or solvents that could damage the finish or materials.
• Inspection: Periodically inspect all components for signs of wear, damage, or corrosion. Pay close attention to the steel fittings and the integrity of the PVC coating.
• Fastener Check: Re-check the tightness of all mounting bolts and screws every few months, or after significant use, to ensure they remain secure.
• Lubrication: If the anti-theft lock mechanism becomes stiff, apply a small amount of graphite lubricant.
• Storage: If the roof bars are removed for extended periods, store them in a dry, protected environment to prevent environmental damage.

7. Troubleshooting

Should you encounter any issues with your La Prealpina LP49 roof bars, consider the following:

• Excessive Noise/Vibration: Ensure all components are tightly secured. Check if cargo is properly distributed and fastened. Adjust the position of the bars if possible, or consider adding a fairing if available for your model.
• Difficulty with Installation: Re-read the specific installation instructions provided with the fixing kit. Ensure you have the correct fixing kit for your vehicle model and year.
• Loose Bars: Immediately stop driving and re-tighten all mounting bolts. If the issue persists, inspect the attachment points on your vehicle and the roof bar components for any damage.
• Lock Malfunction: Ensure the key is fully inserted and turned correctly. If the lock is stiff, apply a small amount of lubricant. Do not force the lock.

If problems persist or you suspect a defect, contact La Prealpina customer support or your retailer for assistance.
