Troubleshooting
Common Issues and Solutions
- Missing or Damaged Parts:
Issue: Components are missing from the package or appear damaged upon arrival.
Solution: Carefully check all items against the parts list in the instruction manual. If parts are genuinely missing or damaged, contact OSCHF customer service for replacements. - Difficulty Aligning Panels:
Issue: Panels do not seem to fit together or align correctly during assembly.
Solution: Double-check the orientation of each panel. Some back panels may be mirror images and need to be matched correctly. Ensure you are using the correct hardware for each connection point. Refer to the detailed diagrams in the PDF manual. - Unstable or Wobbly Bookcase:
Issue: The assembled bookcase feels unstable or wobbles.
Solution: Verify that all screws, dowels, and cam locks are fully tightened. Ensure the back panels are securely attached, as they provide significant structural support. Confirm the bookcase is placed on a level surface. Most importantly, ensure the anti-tipping device is properly installed and anchored to a wall stud. - Scratches or Marks on Surface:
Issue: Minor scratches or marks appear on the surface.
Solution: The melamine finish is scratch-resistant, but not scratch-proof. For minor marks, a furniture repair marker matching the wood finish may help. For deeper scratches, contact customer service for advice.
