3. Вміст упаковки

The DNM BURNER-RCP2S Mountain Downhill Bike Rear Shock package includes:

• 1 x DNM BURNER-RCP2S Rear Shock (with 550 lbs coil spring installed)

4. Налаштування та встановлення

Correct installation is crucial for the performance and safety of your rear shock. Ensure your bicycle frame is compatible with the shock's dimensions.

4.1 Перевірка сумісності

• Eye-to-Eye Length: The BURNER-RCP2S has an eye-to-eye length of 190 mm (7.46 inches). Verify this matches your frame's requirement.
• подорожі: The shock provides 51 mm (2.01 inches) of travel.
• Bushing Size: The inner hole size for the bushings is 7.63 mm (0.30 inches). Ensure your frame's mounting hardware is compatible. Some frames may require specific bushing widths; measure your frame's mounting points and adjust bushings if necessary (e.g., by carefully removing material from aluminum bushings to achieve a precise fit).

4.2 Етапи встановлення

1. Підготуйте каркас: Ensure the shock mounting points on your bicycle frame are clean and free of debris.
2. Insert Bushings: If not already installed, insert the appropriate bushings into the shock's eyelets.
3. Mount the Shock: Carefully align the shock with the frame's mounting points. Insert the mounting bolts through the frame, bushings, and shock eyelets.
4. Затягніть болти: Hand-tighten the mounting bolts initially. Refer to your bicycle frame manufacturer's specifications for the correct torque values. Over-tightening can damage the shock or frame.
5. Перевірте зазор: Cycle the suspension through its full travel to ensure there is no interference with the frame, tires, or other components.

5. Інструкції з експлуатації та налаштування

The BURNER-RCP2S offers several adjustments to customize your ride feel. Experiment with settings in a safe environment to find your preferred setup.

5.1 Rebound Adjustment

Rebound controls the speed at which the shock extends after compression. This adjustment is typically made via a red dial located at the bottom of the shock.

• "Fast" (Counter-Clockwise): Turning the dial counter-clockwise speeds up the rebound. This is often preferred for quick recovery over successive bumps.
• "Slow" (Clockwise): Turning the dial clockwise slows down the rebound. This can provide more control and prevent the shock from "bucking" the rider on larger impacts. For climbing or a firmer feel, turning the rebound dial fully counter-clockwise can achieve a near-lockout state.

5.2 Compression Adjustment

Compression controls how quickly the shock compresses when subjected to force. This adjustment is typically made via a blue knob located on the piggyback reservoir.

• "Hard" (Clockwise): Turning the knob clockwise increases compression damping, making the shock feel firmer and less prone to bottoming out.
• "Soft" (Counter-Clockwise): Turning the knob counter-clockwise decreases compression damping, making the shock feel softer and more responsive to small bumps.

5.3 Регулювання попереднього натягу

Preload refers to the initial compression of the coil spring. It is adjusted by turning the spring collar located at the top of the coil spring.

• прирістasing Preload: Turn the spring collar clockwise to compress the spring further. This increases the initial force required to move the shock, reducing sag and making the suspension feel firmer.
• Декретasing Preload: Turn the spring collar counter-clockwise to release spring tension. This increases sag and makes the suspension feel softer.
• Важлива примітка: Do not exceed 2 to 3 full turns of preload beyond the point where the spring collar first contacts the spring. Excessive preload can damage the spring or shock and negatively affect performance.

6. Технічне обслуговування

Proper maintenance ensures the longevity and consistent performance of your DNM BURNER-RCP2S rear shock. This shock is designed to be relatively low-maintenance.

• Прибирання: After each ride, especially in muddy or dusty conditions, clean the shock body, shaft, and spring with mild soap and water. Rinse thoroughly and wipe dry with a soft cloth. Avoid high-pressure washers directly on seals.
• Огляд: Regularly inspect the shock for any signs of wear, damage, or leaks. Check for scratches on the damper shaft, which can compromise seals. Ensure all mounting bolts are securely tightened to the manufacturer's recommended torque.
• Змащення: Keep the exposed damper shaft clean and free of grit. A small amount of silicone-based suspension lubricant can be applied to the shaft and wiper seal to maintain suppleness, but avoid petroleum-based products.
• Сервіс: While the BURNER-RCP2S is designed for durability, internal service may be required over time. For internal maintenance or seal replacement, it is recommended to contact an authorized DNM service center. Do not attempt to open the high-pressure damper unit yourself.

7. Вирішення проблем

This section addresses common issues you might encounter with your rear shock.

• Issue: Poor Damping Performance / Excessive Bounciness
  рішення: Check your rebound adjustment. If the shock is returning too quickly, increase rebound damping (turn the red dial clockwise towards "Slow"). Ensure the spring preload is not excessively loose.
• Issue: Shock Bottoming Out Frequently
  рішення: Збільшення стиснення damping (turn the blue knob clockwise towards "Hard"). Ensure your spring preload is set correctly for your weight and riding style. If the issue persists, a stiffer spring rate might be required.
• Issue: Shock Feels Too Stiff / Not Using Full Travel
  рішення: Decrease compression damping (turn the blue knob counter-clockwise towards "Soft"). Reduce spring preload (turn the spring collar counter-clockwise). Ensure the spring rate is appropriate for your weight.
• Issue: Unusual Noises (e.g., Squeaking, Clunking)
  рішення: Inspect all mounting bolts for proper torque. Check for any loose components or foreign objects. Clean the shock thoroughly. If noises persist, discontinue use and consult a professional mechanic.
• Issue: Oil Leakage
  рішення: A small amount of oil residue on the damper shaft is normal. However, if there is significant oil leakage, this indicates a seal failure. Discontinue use immediately and contact an authorized service center for repair.
