Informazioni importanti sulla sicurezza

AVVERTIMENTO: Improper installation or adjustment of suspension components can lead to serious injury or death. Always wear appropriate personal protective equipment, including eye protection. If you are not confident in your ability to safely install or adjust this product, seek assistance from a qualified professional.

• Prima di lavorare sotto, assicurarsi che il veicolo sia saldamente appoggiato su cavalletti o su un sollevatore.
• Never work on a vehicle supported only by a jack.
• Per le specifiche e le procedure di coppia di serraggio specifiche, fare riferimento al manuale di manutenzione del veicolo.
• Tenere le mani e gli indumenti lontani dalle parti in movimento.

Istruzioni per l'installazione

1. Preparare il veicolo: Safely lift and support the vehicle using jack stands or a hydraulic lift. Ensure the suspension is unloaded.
2. Rimuovere i vecchi ammortizzatori: Locate and remove the existing shock absorbers. This typically involves unbolting the upper and lower mounting points. Retain any reusable hardware if applicable.
3. Ispezionare i punti di montaggio: Clean and inspect the vehicle's shock mounting points for any damage, corrosion, or wear. Repair as necessary.
4. Installare nuovi ammortizzatori:
   • Install the provided polyurethane bushings or bearing mounting hardware onto the QA1 TD902 shock.
   • Position the new shock absorber into the upper mounting point and secure it with the appropriate hardware. Do not fully tighten at this stage.
   • Extend or compress the shock as needed to align with the lower mounting point. Secure with hardware.
5. Fissaggi di coppia: With the vehicle's weight on the suspension (or at ride height), tighten all mounting bolts to the vehicle manufacturer's specified torque values. Refer to your vehicle's service manual.
6. Controllo finale: Double-check all fasteners for proper torque. Ensure there is no interference with other suspension or vehicle components.

Nota: For coil-over applications, specific coil-over hardware will be included and should be installed according to the separate coil-over instructions.

Regolazione e funzionamento

The QA1 TD902 is a double adjustable shock, allowing independent control over compression (bump) and rebound (extension) damping. This enables fine-tuning of your vehicle's ride and handling characteristics.

Procedura di adeguamento:

1. Locate Adjusters: The shock features two adjustment knobs, typically located at the bottom of the shock body. One knob controls compression, and the other controls rebound. Refer to the markings (e.g., 'C' for Compression, 'R' for Rebound) on the shock body.
2. Impostazioni iniziali: It is recommended to start with both compression and rebound adjusters set to a neutral or manufacturer-recommended baseline. This is often achieved by turning the knob fully counter-clockwise until it stops (zero clicks), then turning it clockwise a specified number of clicks. Consult QA1 documentation for specific baseline settings if available.
3. Adjusting Compression: Turning the compression knob clockwise increases the damping force during shock compression (when the wheel moves upwards). This can help control body roll and dive.
4. Adjusting Rebound: Turning the rebound knob clockwise increases the damping force during shock extension (when the wheel moves downwards). This helps control how quickly the wheel returns to its original position after hitting a bump, improving tire contact with the road.
5. Aggiustamenti incrementali: Make small adjustments (1-2 clicks at a time) and test the vehicle's behavior. Note your settings for future reference.
6. Simmetria: Ensure that adjustments are made symmetrically across the vehicle (e.g., both front shocks, or both rear shocks) unless specific tuning requires otherwise.

Mancia: Keep a log of your adjustment settings and how they affect vehicle performance to find your optimal setup for different driving conditions.

Manutenzione

Regular maintenance helps ensure the longevity and optimal performance of your QA1 TD902 shock absorbers.

• Ispezione regolare: Periodically inspect the shocks for any signs of leaks, damage to the body or piston rod, or worn bushings.
• Pulizia: Keep the shock bodies and piston rods clean, especially after driving in dirty or corrosive conditions. Use mild soap and water, then rinse thoroughly. Avoid harsh chemicals that could damage seals.
• Controllo hardware: Verify that all mounting hardware remains tight and secure. Re-torque fasteners to specification if necessary.
• Piston Rod Protection: Avoid scratching or damaging the piston rod surface, as this can lead to seal failure and fluid leaks.
• Boccole: Inspect polyurethane bushings for cracking or excessive wear. Replace them if they show signs of degradation.
