5. Operating Instructions
Reversible Storage Shelves:
The 3-tier storage shelves can be installed on either the left or right side of the desk during assembly to best fit your room layout and personal preference. This flexibility allows you to customize your workspace for optimal efficiency.

Adjustable Leveling Feet:
The desk is equipped with adjustable leveling feet to ensure stability on uneven floor surfaces. To adjust, simply rotate the feet clockwise or counter-clockwise until the desk is level and stable. This prevents wobbling and provides a secure foundation for your work or gaming setup.

6. Maintenance and Care
Cleaning the Desktop:
The desk features a durable, waterproof, and scratch-resistant surface. To clean, simply wipe with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish. For spills, wipe immediately to prevent staining.

General Care:
- Periodically check all screws and connections to ensure they remain tight. Re-tighten as necessary.
- Avoid placing extremely hot or cold items directly on the desktop without protective coasters.
- Do not drag the desk when moving it; lift it to prevent damage to the legs and floor.
7. Troubleshooting
Desk is Wobbly:
- Solution: Check if the desk is on an uneven surface. Adjust the leveling feet at the bottom of each leg until the desk is stable.
- Solution: Ensure all screws connecting the metal frame components and the desktop are securely tightened. Over time, screws may loosen and require re-tightening.
- Solution: Verify that the X-brace support bars are correctly installed and tightened. These provide crucial structural stability.
Parts Do Not Align During Assembly:
- Solution: Do not fully tighten screws until all parts for a section are loosely assembled. This allows for minor adjustments. Once all parts are in place, then tighten all screws.
- Solution: Double-check the part numbers against the assembly diagram to ensure you are using the correct components for each step.
Missing or Damaged Parts:
- Solution: Carefully review the package contents list and assembly video. If parts are genuinely missing or damaged, contact DUMOS customer support for assistance.
