Operating Instructions
Your Yaheetech office chair offers several adjustable features for personalized comfort:
- Adjustable Seat Height: To raise the seat, lift the lever located under the seat while taking your weight off the chair. To lower the seat, lift the lever while seated. The adjustable range is 4 inches.
- Rocking Function: The chair features a rocking function. Turn the control knob located under the seat to adjust the tilt tension. This allows you to customize the resistance when leaning back.
- 360° Swivel: The chair is designed with a 360-degree swivel capability, allowing for easy rotation and access to different areas without moving the base.

Maintenance
To ensure the longevity and appearance of your chair, follow these simple maintenance guidelines:
- Cleaning: Wipe clean with a damp cloth. For faux leather upholstery, use a mild soap solution if necessary, then wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Regular Checks: Periodically inspect all screws and connections to ensure they remain tight. Re-tighten if any looseness is detected.
- Caster Care: Keep casters free of hair and debris to ensure smooth rolling.

Troubleshooting
If you encounter any issues with your chair, please refer to the following common solutions:
- Chair not adjusting height: Ensure the black plastic cap has been removed from the gas lift cylinder. Check if the lever mechanism is obstructed or damaged.
- Chair wobbles: Verify that all assembly screws are securely tightened, especially those connecting the seat to the backrest and the base to the gas lift. Ensure the casters are fully inserted into the base.
- Casters not rolling smoothly: Check for any debris (hair, lint, etc.) wrapped around the caster wheels and remove them.
- Squeaking noises: Apply a small amount of silicone lubricant to moving parts, such as the gas lift or rocking mechanism.
