3. Setup

3.1 Installation

Install the DNM AOY-36RC rear shock onto your mountain bike frame using appropriate hardware (not included). Ensure all bolts are tightened to the manufacturer's recommended torque specifications for your bike frame. Verify that the shock moves freely through its travel without any binding or interference.

3.2 Air Pressure Adjustment

The air spring pressure is crucial for proper shock performance and rider sag. A high-pressure shock pump (such as the BUCKLOS 300 Psi pump) is required for this adjustment. The default air pressure setting is 100 PSI. It is recommended to keep the pressure below 180 PSI for self-adjustment.

1. Remove the air suspension cap from the shock's air valve.
2. Securely connect the shock pump to the air valve. Tighten the silver knob clockwise, then the red knob clockwise to ensure a sealed connection.
3. Observe the pressure gauge. If the pressure is too low, pump air into the shock until the desired PSI is reached.
4. If the pressure is too high, gently press the bleeder button on the pump to release air in small increments until the desired pressure is achieved.
5. To disconnect the pump, first loosen the red knob counter-clockwise to reset the valve position and prevent air leaks. Then, loosen the silver knob counter-clockwise and gently pull the pump valve out.
6. Reinstall the air suspension cap.

3.3 Rebound Adjustment

The red knob on the shock controls the rebound damping. Turning the knob clockwise slows down the rebound (slower return to extended position), while turning it counter-clockwise speeds up the rebound (faster return). Adjust this setting to match your riding style and terrain for optimal control and comfort.

3.4 Lockout Function

The blue lever on the shock activates the lockout function. Engaging the lockout stiffens the shock, reducing suspension movement. This is useful for climbing or riding on smooth terrain to improve pedaling efficiency. Disengage the lockout for descending or rough terrain to allow full suspension travel.

4. Operating Instructions

Once installed and adjusted, the DNM AOY-36RC is ready for use. Remember to adjust air pressure and damping settings according to your weight, riding style, and terrain conditions. Regularly check all mounting bolts for tightness before each ride.

5. Maintenance

• Cleaning: After each ride, clean the shock body and shaft with mild soap and water. Avoid high-pressure washing directly on seals.
• Inspection: Regularly inspect the shock for any signs of damage, leaks, or excessive wear on seals and bushings.
• Lubrication: Keep the shock shaft clean and lightly lubricated with a suspension-specific lubricant.
• Service: For internal maintenance or if you notice a significant drop in performance, it is recommended to have the shock serviced by a qualified bicycle mechanic.

6. Troubleshooting

• Loss of Air Pressure: Check the air valve for proper sealing. Ensure the valve core is tight. If pressure loss persists, internal seals may need replacement.
• Poor Damping Performance: Verify air pressure is set correctly. Adjust rebound damping. If issues continue, the internal damping system may require service.
• Unusual Noises: Inspect mounting hardware for tightness. Check for any rubbing components. If noises persist, consult a mechanic.
