3. Setup and Assembly
Assembly of the UNICOO L-Shaped Standing Desk requires careful attention to detail. It is highly recommended that two people participate in the assembly process due to the desk's weight and size. Ensure you have ample floor space for laying out components and performing the assembly steps. While the instructions are provided with the product, some users have noted that they can be challenging; patience and methodical work are key. The tabletop comes in three pieces, which are joined by metal plates and screws during assembly.

Assembly Tips:
- Identify all parts and hardware before starting.
- Follow the provided assembly manual step-by-step.
- When attaching the tabletop sections, ensure they are aligned correctly before tightening screws.
- For easier final placement, consider assembling the desk upside down and then carefully flipping it over with assistance once complete.
- Ensure the motor rods (if applicable, for crank mechanism) are correctly oriented and engaged before final assembly to ensure smooth lifting.
4. Operating Instructions
The UNICOO L-Shaped Standing Desk features a manual crank system for height adjustment, allowing seamless transitions between sitting and standing positions.
Height Adjustment:
- Locate the manual crank handle, typically positioned on the right side of the desk.
- Unfold the crank handle if it is in the folded, space-saving position.
- To raise the desk, turn the crank handle clockwise.
- To lower the desk, turn the crank handle counter-clockwise.
- Adjust the desk to your desired height within the range of 27.5 inches (minimum) to 45.3 inches (maximum).
- Once the desired height is reached, you may fold the crank handle back to its tucked position to save space.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your UNICOO standing desk.
- Cleaning: Wipe the desk surfaces with a damp cloth. Avoid harsh chemicals or abrasive cleaners that may damage the finish.
- Inspection: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary.
- Crank Mechanism: Keep the crank mechanism free of dust and debris. If the crank feels stiff, a small amount of silicone-based lubricant can be applied to moving parts, avoiding contact with the tabletop.
- Weight Distribution: Distribute weight evenly across the desk surface to prevent undue stress on the frame.
6. Troubleshooting
If you encounter issues with your UNICOO L-Shaped Standing Desk, refer to the following common problems and solutions:
- Desk does not move up or down when cranking:
- Ensure the crank handle is fully engaged and not slipping.
- Check if the internal rods connecting the crank mechanism to the legs are properly inserted and aligned. Misalignment can prevent movement.
- Inspect for any obstructions preventing the legs from moving freely.
- Desk is wobbly:
- Verify that all assembly screws and bolts are securely tightened.
- Ensure the desk is placed on a level surface. Use the adjustable feet to compensate for uneven floors.
- Check that the tabletop sections are firmly joined and not loose.
- Difficulty with assembly:
- Refer back to the assembly instructions provided with the product.
- Ensure you have sufficient space and, if possible, a second person to assist.
- Double-check that the correct screws are used for each step, as some may appear similar.
If these steps do not resolve the issue, please contact UNICOO customer support for further assistance.
