8. Maintenance
- Regularly check all screws and connections to ensure they remain tight and secure.

9. Troubleshooting
9.1 Monitor Drifts Down or Up
Solution: Adjust the gas spring tension. If the monitor drifts down, increase tension by turning the adjustment screw clockwise. If it drifts up, decrease tension by turning counter-clockwise. Refer to Section 6.1 for detailed instructions.
9.2 Monitor Arm is Wobbly
Solution:
- Ensure the desk clamp or grommet mount is securely tightened to the desk.
- Check that the VESA plate is firmly attached to both the monitor and the arm.
- Verify that your desk surface is stable and not flexing under the weight.
9.3 Difficulty Moving the Arm
Solution: The arm's joints may be too tight. Loosen the corresponding screws slightly with the hex key until movement is smooth but still holds position. Do not loosen excessively.
