Operating Instructions
Once assembled, your Yaheetech shelving unit is ready for use. To optimize your storage, consider the following:
- Load Distribution: Distribute weight evenly across each shelf. While each shelf can hold up to 175 kg, avoid concentrating heavy items in one small area.
- Adjusting Shelf Height: To adjust a shelf's height, carefully unload the shelf, disassemble the beams from the uprights at the desired level, and reassemble them into the new slots. Ensure all connections are secure before reloading.
- Versatile Placement: The unit's robust construction makes it suitable for various environments, from a garage or workshop for heavy tools to a living room or kitchen for household items.

Maintenance
To ensure the longevity and continued performance of your shelving unit, follow these simple maintenance guidelines:
- Cleaning: Wipe down the metal frame and MDF shelves with a damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the protective coating.
- Rust Resistance: The metal frame is coated with a waterproof and rust-resistant coating. However, prolonged exposure to excessive moisture should be avoided.
- Regular Inspection: Periodically check all connections to ensure they remain secure. Tighten any loose components if necessary.
- MDF Care: While the MDF shelves are designed to resist deformation, avoid exposing them to excessive moisture or extreme temperature fluctuations.
Troubleshooting
If you encounter any issues with your shelving unit, refer to the following common problems and solutions:
- Unit feels unstable after assembly: Ensure all beams are fully seated into the upright slots. Verify that the unit is placed on a flat, level surface. The anti-slip footpads should provide additional stability.
- Shelf bowing or sagging: This indicates overloading. Reduce the weight on the affected shelf, ensuring the load does not exceed 175 kg. Distribute weight evenly.
- Difficulty during assembly: Refer to the included assembly instruction manual for detailed diagrams. Ensure you are wearing protective gloves to prevent injury from sharp edges. If components are difficult to fit, double-check alignment.
