Setup and Installation
Important Safety Note: Professional installation is recommended. Ensure all components are securely fastened before riding. Incorrect installation can lead to product failure and injury.
- Preparation: Gather all necessary tools, including appropriate hex keys for your bike's mounting bolts and a high-pressure shock pump.
- Remove Old Shock (if applicable): Carefully detach the existing rear shock from your bicycle frame. Note the orientation and any spacers used.
- Install New Shock: Align the MEROCA HLT-H5 shock absorber with the mounting points on your frame. Insert the provided bolts and secure them firmly. Do not overtighten.
- Initial Air Pressure Setting: The shock absorber is factory-set with an initial air pressure of approximately 100 PSI.
- Adjust Air Pressure: Using a compatible shock pump, adjust the air pressure to suit your weight and riding style. Refer to the 'Operating Instructions' section for detailed adjustment guidance.
- Check for Clearance: Before riding, ensure the shock absorber has adequate clearance from other bike components (e.g., frame, tires, cables) throughout its full range of travel.

Operating Instructions
The MEROCA HLT-H5 allows for air pressure adjustment to customize your ride's comfort and performance. Proper adjustment is crucial for optimal shock absorption.
Air Pressure Adjustment
- Determine Sag: Sag is the amount the shock compresses under your body weight. To measure, sit on your bike in your normal riding position (with all riding gear). Have someone measure the exposed shaft length. Then, lift yourself off the bike and measure the full exposed shaft length. The difference is your sag.
- Increase Pressure: If the sag is too much (shock compresses too easily), connect a shock pump to the air valve and add air in small increments.
- Decrease Pressure: If the sag is too little (shock feels too stiff), carefully press the valve core to release air in small increments.
- Test and Refine: Ride the bike on varied terrain and make small adjustments until you achieve the desired feel and performance. Optimal sag typically ranges from 20-30% of the shock's total travel, depending on riding style and terrain.
CAUTION: Do not exceed 180 PSI when adjusting the air pressure. Exceeding this limit may cause excessive air pressure and damage the cylinder.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your MEROCA HLT-H5 shock absorber.
- Regular Cleaning: Keep the shock absorber clean from dirt, mud, and debris. Use a soft cloth and mild, non-abrasive soap with water. Avoid using high-pressure washers directly on seals or the air valve.
- Inspect Seals: Periodically check the external sealing rings for any signs of wear, cracking, or damage. Damaged seals can lead to air leaks or contamination.
- Lubrication: The DU self-lubricating bushings require minimal maintenance. However, ensure the exposed shaft (stanchion) remains clean and free of grit. A small amount of suspension-specific lubricant can be applied to the shaft if it appears dry, but avoid petroleum-based lubricants.
- Pressure Check: Regularly check the air pressure (e.g., before each ride or weekly) and adjust as needed to maintain your desired sag and performance.
- Storage: Store your bicycle in a clean, dry environment away from extreme temperatures and direct sunlight.

Troubleshooting
This section addresses common issues you might encounter with your MEROCA HLT-H5 Air Pressure Rear Shock Absorber.
| Problem | Possible Cause | Solution |
|---|---|---|
| Shock feels too stiff | Air pressure too high, Incorrect sag setting | Reduce air pressure using a shock pump, Adjust sag according to operating instructions |
| Shock bottoms out easily | Air pressure too low, Incorrect sag setting | Increase air pressure using a shock pump, Adjust sag according to operating instructions |
| Air leaks from valve | Loose valve cap, Damaged valve core | Ensure valve cap is tightened, Replace valve core if damaged |
| Excessive play/movement | Loose mounting bolts, Worn bushings | Check and tighten mounting bolts to recommended torque, Inspect and replace bushings if worn |
| Shock feels "sticky" or not smooth | Dirt/debris on shaft, Dry seals | Clean shaft and seals thoroughly, Apply a small amount of suspension-specific lubricant to the shaft |
