6. Maintenance
- Cleaning: Wipe the arm with a soft, dry cloth to remove dust. Avoid abrasive cleaners or solvents.
- Joint Tension: Periodically check the tension of the joints. If the arm feels too loose or too stiff, use the provided hex keys to adjust the tension screws until the desired resistance is achieved.
- Cable Management: Ensure cables are not pinched or excessively bent within the cable trays to prevent damage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Arm is too loose/sags | Joint tension is too low for the attached equipment. | Use the hex keys to tighten the tension screws at the joints until the arm holds its position. |
| Arm is too stiff/difficult to move | Joint tension is too high. | Use the hex keys to loosen the tension screws at the joints until the arm moves smoothly. |
| Desk clamp is unstable | Clamp not tightened sufficiently or desk surface is uneven. | Ensure the clamp screw is fully tightened. If the desk surface is uneven, consider using a protective pad (not included) to create a stable contact point. |
| Cables are visible or messy | Cable management covers are open or cables are not routed correctly. | Open the magnetic covers, route cables neatly through the internal channels, and re-attach the covers. |
