4. Maintenance
To ensure the longevity and optimal performance of your keyboard tray, follow these simple maintenance guidelines:
- Cleaning: Wipe the tray and metal components with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that may damage the finish.
- Fasteners: Periodically check all screws and fasteners to ensure they are tight. Retighten if necessary to maintain stability.
- Movement Mechanism: Keep the sliding and rotating mechanisms free of dust and debris to ensure smooth operation.
5. Troubleshooting
If you encounter any issues with your keyboard tray, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tray feels wobbly (left to right) | Loose mounting screws or inherent slight play in the slide mechanism. | Ensure all mounting screws are securely tightened. While some minimal play may be present due to design, proper installation minimizes this. |
| Tray is difficult to pull out or push in | Friction in the sliding mechanism (metal-on-metal) or weight on the tray. | Slightly lift the tray as you pull it out or push it in to reduce friction. Ensure the mechanism is clean and free of debris. |
| Adjustment knob interferes with knees | Placement of the knob relative to user's leg position. | Adjust your seating position or the tray's height/depth to minimize interference. This is a design characteristic. |
| Tray does not hold position after adjustment | Adjustment knob is not sufficiently tightened. | Ensure the adjustment knob is tightened firmly after setting the desired height or tilt. |
If these solutions do not resolve the issue, please contact customer support.
