5. Operating and Adjustments
The MOUNTUP monitor arm offers full motion capabilities for optimal viewing comfort.

Figure 5.1: The monitor arm provides extensive adjustability for ergonomic positioning.
5.1 Gas Spring Tension Adjustment
Adjust the gas spring tension to match your monitor's weight for smooth and stable positioning. Keep the arm in a horizontal position during adjustment.

Figure 5.2: Adjusting the gas spring tension for optimal monitor support.
- If the arm shoots up: Turn the adjustment screw clockwise ("-" direction) to reduce tension for a lighter monitor.
- If the arm falls down: Turn the adjustment screw counter-clockwise ("+" direction) to increase tension for a heavier monitor.
5.2 Tilt Adjustment
The monitor can tilt +90° (up) and -45° (down) to reduce glare and optimize viewing angles.
- Loosen the tilting bolt on the VESA plate.
- Position the screen to your desired angle.
- Retighten the tilting bolt to fix the angle.
5.3 Swivel and Rotation
The arm allows for extensive swivel and 360° rotation for landscape or portrait orientation.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your monitor mount.
- Cleaning: Wipe the mount with a soft, damp cloth. Avoid abrasive cleaners or solvents that may damage the finish.
- Inspection: Periodically check all screws and connections to ensure they are tight and secure. Retighten if necessary.
- Gas Spring: If the gas spring tension feels off, refer to Section 5.1 for adjustment instructions.
7. Troubleshooting
If you encounter any issues, refer to the following common problems and solutions:
- Monitor arm falls down or shoots up: This indicates incorrect gas spring tension. Refer to Section 5.1 for proper adjustment based on your monitor's weight.
- Monitor tilts forward or backward unexpectedly: The tilting bolt may be loose. Refer to Section 5.2 to loosen, adjust, and retighten the tilting bolt.
- Mount feels unstable or wobbly: Ensure the C-clamp or grommet base is securely tightened to the desk. Check all connection points on the arm and VESA plate.
- Difficulty moving the arm: The tension might be too high for a lighter monitor, or the joints might need lubrication (though typically not required for gas spring arms). Ensure no cables are snagged.
If problems persist, please contact customer support.
