2. Insert Gas Lift: Place the gas lift cylinder into the center hole of the five-star base.

4. Maintenance

Proper care and maintenance will extend the life of your office chair.

• Cleaning: For general cleaning, wipe surfaces with a soft, damp cloth. For spills or stains, spot clean immediately using a mild detergent and a clean cloth. Avoid harsh chemicals or abrasive cleaners, as these can damage the mesh fabric and other materials.
• Inspection: Periodically inspect all screws and bolts to ensure they are tight. Retighten if necessary to maintain stability and safety.
• Casters: Keep casters free of hair and debris to ensure smooth movement.

5. Troubleshooting

If you encounter any issues with your chair, refer to the following common troubleshooting tips:

• Chair Squeaks: Check all bolts and screws and tighten them. A small amount of silicone lubricant can be applied to moving parts if squeaking persists.
• Difficulty Adjusting Height: Ensure the gas lift lever is fully engaged. If the chair does not raise or lower, the gas lift cylinder may need replacement.
• Casters Not Rolling Smoothly: Inspect casters for trapped debris (hair, lint, etc.) and clean them thoroughly.
• Chair Feels Unstable: Verify that all assembly screws are securely tightened and that the chair is on a flat, even surface.
