4. Assembly Instructions
The Yaheetech shelving unit features a boltless design for easy assembly. A rubber mallet (not included) is recommended to ensure components are securely fitted.
- Prepare the Base: Attach the bottom horizontal beams to the vertical posts, ensuring the non-slip scratch-resistant pads are placed at the base of the posts. Use a rubber mallet to gently tap the components into place until they are secure.
- Install Lower Shelves: Insert the MDF boards onto the lower horizontal beams. Ensure they sit flush within the frame.
- Connect Upper Posts: Use the provided connecting pieces to extend the vertical posts to the desired height.
- Install Remaining Shelves: Continue attaching horizontal beams and inserting MDF boards for the remaining shelves. The shelves are adjustable; simply align the notches on the beams with the keyhole slots on the vertical posts at your preferred height and tap into place with a mallet.
- Secure Top Caps: Place the cap ends on the top of the vertical posts to prevent nicks and provide a finished look.
- Optional Configuration: The unit can be assembled as one tall 5-tier unit or separated into two smaller, independent shelving units (e.g., a 3-tier and a 2-tier unit) by utilizing the connecting pieces as top caps for the shorter units.
- Wall Anchoring: For added stability and safety, especially with heavy loads or in areas with potential for tipping, secure the unit to a wall using the provided anti-tipping over kit.

5. Operating Instructions
Once assembled, your Yaheetech shelving unit is ready for use. Its adjustable design allows for versatile storage solutions.
- Loading the Shelves: Distribute weight evenly across each shelf. Do not exceed the maximum load capacity of 386 pounds per shelf or 1930 pounds total for the entire unit.
- Adjusting Shelf Height: To adjust a shelf, unload it completely. Gently tap the horizontal beams upwards with a rubber mallet to disengage them from the keyhole slots. Reposition the beams to the desired height and tap them back into place securely.
- Placement: This unit is suitable for various environments including offices, garages, living rooms, kitchens, workshops, warehouses, and balconies.

6. Maintenance
To ensure the longevity and appearance of your shelving unit:
- Wipe with a dry cloth to clean. Avoid abrasive cleaners or harsh chemicals.
- Regularly check all connections to ensure they remain secure. Re-tap with a rubber mallet if any components feel loose.
- Inspect the MDF boards periodically for any signs of damage or moisture.
7. Troubleshooting
- Unit feels wobbly: Ensure all horizontal beams are fully seated into the keyhole slots on the vertical posts. Use a rubber mallet to firmly tap all connections. Verify the unit is placed on a flat, level surface. If necessary, secure the unit to a wall using the anti-tipping over kit.
- Difficulty assembling components: Ensure components are correctly oriented. A rubber mallet is essential for securely tapping the boltless connections into place.
- Shelves not holding weight: Confirm that the weight on each shelf does not exceed 386 pounds and the total unit weight does not exceed 1930 pounds. Redistribute items if necessary.
