4. Maintenance

Proper maintenance ensures the longevity and performance of your Hbada E3 Air chair:

• Cleaning: Regularly wipe down the chair frame with a soft, damp cloth. For the mesh material, use a mild soap solution and a soft brush, then rinse with a damp cloth and allow to air dry. Avoid harsh chemicals.
• Inspection: Periodically check all screws and connections to ensure they are tight. Retighten if necessary.
• Protection: Keep the chair away from direct heat sources and sharp objects to prevent damage to the mesh and frame.

5. Troubleshooting

If you encounter any issues with your chair, consider the following:

• Parts Damaged or Missing: Do not use the chair if any parts are damaged or missing. Contact customer support for replacements.
• Difficulty Adjusting: Ensure all locking mechanisms are disengaged before attempting to adjust components. Refer to the operating instructions for specific adjustment methods.
• Squeaking Noises: Check all bolted connections and tighten them. A small amount of silicone lubricant can be applied to moving parts if necessary, avoiding contact with mesh.
