4. Instrucións de funcionamento
The air suspension system allows for adjustable ride height and improved stability, especially when carrying heavy loads or towing.
4.1 Axuste da presión do aire
- Use the dual-panel gauge to monitor and adjust the air pressure in each air spring bag independently.
- Increase air pressure to raise the vehicle's rear end and provide additional support for heavy loads, preventing sag and improving handling.
- Decrease air pressure to lower the vehicle's rear end or when driving without a load for a softer ride.
- The system supports up to 4000kg (approximately 8800 lbs) of load. Always adhere to your vehicle's maximum gross vehicle weight rating (GVWR).

5. Mantemento
Regular maintenance ensures the longevity and optimal performance of your air suspension system.
5.1 Comprobacións de rutina
- Inspección visual: Periodically inspect the air spring bags, air lines, and connections for any signs of wear, damage, or leaks.
- Air Pressure Monitoring: Regularly check the air pressure in the bags, especially before and after carrying heavy loads.
- Limpeza: Keep the air compressor and air lines free from dirt and debris.
5.2 Leak Prevention and Detection
Proper installation is crucial to prevent leaks. If a leak is suspected:
- Ensure air lines are cut cleanly and squarely to create a smooth, tight seal when inserted into fittings.
- Verify that all air lines are properly placed and routed, avoiding kinks or sharp bends.
- Use a spray bottle filled with soapy water to spray all fittings and the air bag itself. Bubbles will indicate a leak.
