4. Setup and Installation
4.1 Initial Air Pressure Setting
The factory-set air pressure for the MEROCA H5 shock absorber is typically 100 PSI. When adjusting the air pressure yourself, it is crucial to ensure the pressure does not exceed 180 PSI. Exceeding this limit can cause excessive air pressure and potentially damage the cylinder.
A dedicated shock pump is required for accurate air pressure adjustments. Do not use standard tire pumps, as they may not provide the necessary precision or pressure range.
4.2 Installation onto Vehicle
The MEROCA H5 shock absorber is designed for mountain bikes, scooters, and other frames equipped with a rear shock absorber mount. Ensure the shock absorber length (e.g., 190mm for this model) is compatible with your vehicle's frame.
Mount the shock absorber securely using appropriate hardware. It is recommended to install the shock first, then release all air pressure and compress the bike to ensure proper movement before re-inflating to your desired pressure. This helps in setting the static sag correctly.

5. Operating Instructions
5.1 Adjusting Air Pressure
To optimize your riding experience, adjust the air pressure in the shock absorber to match your weight and preferred riding style. Use a high-pressure shock pump to add or release air.
- To Increase Pressure: Connect the shock pump to the valve and pump air until the desired PSI is reached.
- To Decrease Pressure: Slowly release air from the valve using the pump's bleed button or by gently pressing the valve stem.
Always ensure the pressure remains below 180 PSI to prevent damage. Proper adjustment will provide a balance between comfort and suspension performance.
6. Maintenance
6.1 Cleaning
Regularly clean the exterior of the shock absorber to remove dirt, mud, and debris. Use a soft cloth and mild soap and water. Avoid using harsh chemicals or high-pressure washers directly on the seals.
6.2 Inspection
Periodically inspect the shock absorber for any signs of wear, damage, or air leaks. Pay close attention to the DU bushings and sealing rings. If any damage is observed, discontinue use and seek professional assistance.
6.3 Lubrication
The DU self-lubricating bushings are designed for long-lasting, low-maintenance performance. However, ensuring the shock shaft remains clean and free of grit will prolong the life of the seals and internal components.
7. Troubleshooting
7.1 Shock Not Compressing or Too Stiff
- Check Air Pressure: Ensure the air pressure is not excessively high. Release small amounts of air until the desired compression is achieved.
- Initial Compression: If newly installed, the shock might require initial compression to activate. Release all air, compress the bike, then re-inflate.
7.2 Excessive Sag or Bottoming Out
- Increase Air Pressure: Add air using a shock pump until the desired sag is achieved for your weight. Do not exceed 180 PSI.
7.3 Air Leaking
- Inspect Valve Cap: Ensure the valve cap is tightly secured.
- Check Valve Core: The valve core might be loose or damaged. Tighten or replace if necessary.
- Examine Sealing Rings: Visually inspect the sealing rings for any cracks or damage. If damaged, professional service may be required.
