4. Operating Instructions
Familiarize yourself with the chair's adjustable features for optimal comfort.
Height Adjustment
To adjust the chair's height, locate the 'LIFT' lever on the right side beneath the seat. Pull the lever upwards while sitting on the chair to lower it, or stand up and pull the lever to raise it. Release the lever at your desired height.
Recline Function
The chair features a 90° to 135° recline function. To recline, pull the 'RCL' lever on the left side of the seat upwards and lean back to your desired angle. Release the lever to lock the backrest in position. To return to an upright position, pull the lever and lean forward.

360° Swivel
The chair is designed with a smooth 360-degree swivel system, allowing for easy rotation without moving the base.
Retractable Footrest
To use the footrest, pull the footrest mechanism out from under the seat. Flip the padded section over to create a comfortable support for your legs. Push it back under the seat when not in use.

5. Maintenance
Proper maintenance will extend the life and appearance of your gaming chair.
- Cleaning: Wipe the PU leather surface with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners, which can damage the material.
- Hardware Check: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary to maintain stability.
- Caster Care: Keep the casters clean from dust and debris to ensure smooth rolling.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the PU leather to fade or crack.
6. Troubleshooting
If you encounter any issues with your HLDIRECT gaming chair, refer to the following common problems and solutions:
- Chair is Wobbly or Unstable: Ensure all assembly screws are fully tightened. If the issue persists, disassemble and reassemble, paying close attention to each connection point.
- Height Adjustment Not Working: Check if the gas lift lever is fully engaged. Ensure the gas lift cylinder is correctly inserted into the base and mechanism.
- Backrest Does Not Recline/Lock: Verify that the recline lever is functioning correctly and not obstructed. Ensure no foreign objects are interfering with the reclining mechanism.
- Footrest is Difficult to Extend/Retract: Check for any obstructions in the sliding mechanism. Apply a small amount of silicone lubricant if movement is stiff.
- Lumbar Massage Not Functioning: Ensure the USB cable is securely connected to both the pillow and a working power source. Try a different USB port or power adapter.
- Missing or Ill-fitting Screws: If you find any screws are missing or do not fit properly during assembly, please contact HLDIRECT customer support immediately for assistance and replacement parts.
If these solutions do not resolve the issue, please contact HLDIRECT customer support for further assistance.
