5. Operating Instructions

Your Topstar TEC 50 Counter Swivel Chair is designed for ergonomic comfort and adjustability.

• Seat Height Adjustment: To adjust the seat height, locate the lever on the right side, under the seat. While seated, pull the lever up to lower the seat. To raise the seat, stand up slightly and pull the lever up. Release the lever at the desired height.
• Backrest Adjustment: The backrest can be adjusted for height and angle. Use the knob or lever located on the side or rear of the backrest support to loosen, adjust, and then re-tighten to secure the backrest in your preferred position.
• Swivel Function: The chair is designed to swivel 360 degrees, allowing for easy movement and access to your workspace.
• Foot Ring: The foot ring provides support for your feet, especially at higher seating positions. Adjust its height during assembly or by loosening and re-tightening its fastener on the gas lift.

6. Maintenance and Care

Proper care will extend the life and appearance of your chair.

• Cleaning: The chair's faux leather (PVC/cotton blend) upholstery can be cleaned by wiping with a damp cloth. For stubborn stains, use a mild soap solution and wipe dry immediately. Avoid abrasive cleaners or harsh chemicals.
• Inspection: Periodically inspect all screws, bolts, and connections to ensure they are tight. Re-tighten any loose fasteners to maintain stability and safety.
• Moving the Chair: When moving the chair, lift it rather than dragging it to prevent damage to the gliders and floor.

7. Troubleshooting

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

• Chair is unstable: Check that all assembly screws are fully tightened. Ensure the gliders are properly inserted into the base.
• Seat height adjustment not working: Verify that the gas lift cylinder is correctly seated in both the base and the seat mechanism. Ensure the adjustment lever is functioning freely and not obstructed.
• Squeaking noises: Check for any loose connections and tighten them. A small amount of silicone spray on moving parts (avoiding the gas lift piston) may help, but consult manufacturer guidelines if unsure.

If these steps do not resolve the issue, please contact customer support.
