Operating Instructions
The Yaheetech Mid-Back Mesh Office Chair offers several adjustable features to customize your seating experience:
- Seat Height Adjustment: Locate the lever on the right side, underneath the seat. Pull the lever upwards while seated to lower the seat, or pull it upwards while standing to raise the seat. Release the lever at your desired height.
- Tilt/Rocking Function: The same lever used for height adjustment also controls the tilt. Push the lever inwards to lock the backrest in an upright position. Pull the lever outwards to enable the rocking motion, allowing the chair to recline.
- Tilt Tension Control: A round knob is located underneath the seat, typically towards the front. Rotate this knob clockwise to increase the tension, making the chair harder to recline. Rotate it counter-clockwise to decrease the tension, allowing for easier reclining.
- 360-Degree Swivel: The chair is equipped with a 360-degree swivel function, allowing you to rotate freely without moving the base.
- Rolling Casters: The durable rolling casters allow for smooth movement across various floor surfaces, making it easy to navigate your workspace.
Maintenance
To maintain the quality and appearance of your Yaheetech Mid-Back Mesh Office Chair, simply wipe it clean with a damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these may damage the mesh or fabric. Regularly check all screws and connections to ensure they remain tight for safety and stability.
Troubleshooting
If you encounter any issues with your chair, please consider the following common troubleshooting tips:
- Chair not adjusting height: Ensure the gas lift cylinder is properly installed and the height adjustment lever is fully engaged. If the issue persists, the gas lift may need replacement.
- Chair is wobbly: Check all assembly screws to ensure they are securely tightened. Loose connections are a common cause of wobbling.
- Casters not rolling smoothly: Inspect the casters for any trapped debris (hair, dust, etc.) and clean them thoroughly. Ensure they are fully inserted into the base.
- Backrest not reclining: Verify that the tilt lock lever is disengaged. Adjust the tilt tension knob to a looser setting if the recline is too stiff.
For more complex issues or if troubleshooting steps do not resolve the problem, please contact Yaheetech customer support.
