4.1. Gas Spring Tension Adjustment
The gas spring allows for smooth height adjustments. Adjust the tension to match your monitor's weight for effortless movement.
- Hold the arm in a horizontal position.
- Use the provided Allen key to adjust the gas spring tension screw.
- Turn clockwise (-) to reduce tension for lighter monitors (monitor raises up).
- Turn counter-clockwise (+) to increase tension for heavier monitors (monitor drops down).
- Adjust gradually, testing the arm's movement after every few turns, until the monitor stays at the desired height without drifting. Note: It may take up to 17 turns for significant adjustment.

5. Maintenance
Regular maintenance ensures the longevity and safe operation of your monitor mount.
- Cleaning: Wipe the mount with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Periodic Checks: Periodically check all screws and bolts, especially the clamp/grommet base and VESA plate connections, to ensure they remain tight and secure. Re-tighten if necessary.
- Gas Spring: If the gas spring tension feels off, refer to Section 4.1 for adjustment instructions.
6. Troubleshooting
Refer to the following common issues and solutions. For more detailed assistance, please consult the official Troubleshooting Guide (PDF) available on the product page or contact customer support.
- Monitor Sags or Rises Unintentionally:
This indicates incorrect gas spring tension. Refer to Section 4.1 to adjust the gas spring. Increase tension for heavier monitors (turn counter-clockwise) or decrease for lighter monitors (turn clockwise). - Monitor Tilts Downward:
The tilt bolt may not be sufficiently tightened. Loosen the tilt bolt slightly, adjust the monitor to the desired angle, and then firmly re-tighten the tilt bolt as described in Section 4.2. - Mount Feels Unstable:
Ensure the C-clamp or grommet base is securely fastened to the desk. Check for any wobbling and re-tighten the base screws or clamp knob. Verify that your desk surface is stable and within the specified thickness limits. - Difficulty Moving the Arm:
If the arm is too stiff or too loose, the gas spring tension might need fine-tuning. Refer to Section 4.1. Also, ensure no cables are snagged or obstructing movement.
