• Lubrication: If the chair's moving parts (e.g., swivel, recline mechanism) become stiff, apply a small amount of silicone-based lubricant.

7. Troubleshooting

If you encounter any issues with your Homall S-Racer Gaming Chair, refer to the following common solutions:

• Chair Sinks or Loses Height: This may indicate an issue with the gas lift cylinder. Ensure the height adjustment lever is fully engaged. If the problem persists, the gas lift may need replacement.
• Squeaking Noises: Check and tighten all assembly screws. Lubricate moving parts of the mechanism if necessary.
• Difficulty Reclining/Rocking: Ensure the recline lever is disengaged. Adjust the tension knob beneath the seat for the rocking function.
