Інструкцыя па ўстаноўцы

  1. Падрыхтуйце аўтамабіль: Safely lift and support the vehicle using jack stands or a hydraulic lift. Ensure the suspension is unloaded.
  2. Выдаліце ​​старыя амартызатары: Locate and remove the existing shock absorbers. This typically involves unbolting the upper and lower mounting points. Retain any reusable hardware if applicable.
  3. Праверце кропкі мацавання: Clean and inspect the vehicle's shock mounting points for any damage, corrosion, or wear. Repair as necessary.
  4. Усталюйце новыя амартызатары:
    • 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. Крутоўны момант крапяжу: 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. Канчатковая праверка: Double-check all fasteners for proper torque. Ensure there is no interference with other suspension or vehicle components.

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

Рэгуляванне і эксплуатацыя

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.

Працэдура карэкціроўкі:

  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. Пачатковая налада: 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. Паступовыя карэкціроўкі: Make small adjustments (1-2 clicks at a time) and test the vehicle's behavior. Note your settings for future reference.
  6. Сіметрыя: Ensure that adjustments are made symmetrically across the vehicle (e.g., both front shocks, or both rear shocks) unless specific tuning requires otherwise.

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

Тэхнічнае абслугоўванне

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

  • Рэгулярны агляд: Periodically inspect the shocks for any signs of leaks, damage to the body or piston rod, or worn bushings.
  • Чысціня: 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.
  • Праверка абсталявання: 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.
  • Ўтулкі: Inspect polyurethane bushings for cracking or excessive wear. Replace them if they show signs of degradation.

Ліквідацыю непаладак

If you experience issues with your QA1 TD902 shock absorbers, consult the following common troubleshooting steps:

СімптомМагчымая прычынаРашэнне
Празмернае падскокванне/дрэнны кантроль над яздойНяправільны damping settings (too soft), worn shock, insufficient spring rate.Increase compression and/or rebound damping. Inspect for leaks or damage. Consult a suspension specialist.
Harsh Ride/Stiff SuspensionНяправільны damping settings (too stiff), incorrect spring rate.Decrease compression and/or rebound damping. Ensure adjustments are symmetrical.
Fluid Leaks from Shock BodyDamaged seal, bent piston rod, internal component failure.A leaking shock requires replacement or professional rebuilding. Contact QA1 support.
Грукат або бразгатНяшчыльнае мацаванне, зношаныя ўтулкі, пашкоджанні ад унутранага ўдару.Check and re-torque all mounting bolts. Inspect bushings for wear. If noise persists, inspect the shock for internal damage.

If these steps do not resolve the issue, contact QA1 technical support for further assistance.
