Operating Instructions

• Seat Height Adjustment: Use the lever located under the right side of the seat to adjust the seat height. Pull the lever up to raise the seat; release it at the desired height. To lower, sit on the chair, pull the lever up, and release when the desired height is reached. The seat height can be adjusted from 18.1 inches (46 cm) to 22 inches (56 cm).
• Backrest Recline: The backrest can recline up to 135 degrees. Use the lever on the left side of the seat to unlock the recline function. Lean back to the desired angle and push the lever down to lock it in place. To return to an upright position, pull the lever up, lean forward slightly, and release the lever.
• Armrest Adjustment: The armrests are height-adjustable. Locate the button or lever on the side of each armrest. Press or lift it to move the armrest up or down. Release the button/lever at the desired height. Armrest height can be adjusted from 24.5 inches (63 cm) to 28.3 inches (79 cm).
• Lumbar Support: The chair features strong lumbar support. This support is designed to conform to the natural curve of your lower back, promoting good posture.
• Mobility: The 6-inch electroplated racing wheels allow for smooth movement across hard floors and carpets, enabling easy repositioning within your workspace.

Maintenance

• Cleaning: Wipe the chair clean with a damp cloth. For stubborn stains, use a mild soap solution and then wipe with a clean, damp cloth. Avoid harsh chemicals or abrasive cleaners.
• Regular Checks: Periodically inspect all screws, bolts, and connections to ensure they are tight. Re-tighten if necessary to maintain stability and safety.
• Caster Care: Keep the casters free of hair, dust, and debris to ensure smooth rolling. Clean them regularly.
• Avoid Overloading: Do not place excessive weight on the chair or use it for purposes other than its intended use as an office chair.

Troubleshooting

• Chair Sinks or Loses Height: If the chair gradually sinks or does not maintain its height, the gas lift cylinder may be faulty. Contact customer support for a replacement. Ensure you are within the specified weight capacity.
• Chair is Wobbly: Check all assembly screws and bolts, especially those connecting the seat, backrest, and armrests to the mechanism and base. Tighten any loose connections. Ensure the casters are fully inserted into the base.
• Casters Not Rolling Smoothly: Inspect the casters for any trapped debris (hair, lint, etc.). Clean them thoroughly. Ensure the chair is on an appropriate surface (hard floor or carpet).
• Difficulty Adjusting Recline/Height: Ensure no obstructions are preventing the levers from moving freely. Check if the mechanism is properly installed and not damaged.
