4. Operating Instructions

Your VECELO office chair offers several adjustment features to customize your seating experience.

• Height Adjustment: To adjust the seat height, pull the lever located under the right side of the seat upwards. While holding the lever, raise or lower your body to the desired height. Release the lever to lock the height.
• 360-Degree Swivel: The chair is equipped with a 360-degree swivel function, allowing for easy rotation in any direction.
• Flip-Up Armrests: The armrests can be flipped up by rotating them upwards. This feature allows the chair to be pushed closer to a desk or stored more compactly when not in use.
• Lumbar Support: The S-shaped backrest provides integrated lumbar support. While not manually adjustable in position, its ergonomic design is intended to support the natural curve of your spine.

5. Maintenance

Regular maintenance will help prolong the life and performance of your VECELO office chair.

• Cleaning: Wipe down plastic and metal parts with a soft, damp cloth. For mesh fabric, use a mild soap solution and a soft brush, then blot dry. Avoid harsh chemicals or abrasive cleaners.
• Check Fasteners: Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain stability and safety.
• Caster Care: Keep casters free of hair and debris to ensure smooth movement. Clean them regularly.
• Gas Lift: The gas lift is a sealed unit and requires no user maintenance. If you experience issues with height adjustment, refer to the troubleshooting section or contact customer support.

6. Troubleshooting

If you encounter any issues with your VECELO office chair, please refer to the following common solutions:

• Chair is unstable/wobbly: Ensure all screws and bolts are securely tightened. Check that the gas lift is properly seated in the base and seat mechanism.
• Height adjustment not working: Verify that the gas lift lever is fully engaged. If the issue persists, the gas lift may be faulty and require replacement. Contact customer service.
• Casters not rolling smoothly: Check casters for trapped debris (hair, lint, etc.) and clean them thoroughly. Ensure casters are fully inserted into the base.
• Squeaking noises: Apply a small amount of silicone lubricant to moving parts or connections where squeaking occurs. Avoid applying lubricant to the gas lift cylinder.

If these steps do not resolve the issue, please contact VECELO customer service for further assistance.
