6. Troubleshooting
This section addresses common issues that may arise during assembly or use.
6.1 Assembly Challenges
- Parts Missing or Damaged: Before starting assembly, carefully check all components against the parts list. If parts are missing or damaged, contact Keter customer support immediately. Do not proceed with assembly using incomplete or damaged parts.
- Panels Not Aligning: Ensure the foundation is perfectly level. Uneven ground can cause panels to misalign. Re-check the levelness of your base and adjust as needed.
- Screws Not Fitting: Verify you are using the correct screws for each step as indicated in the manual. If screws do not fit, ensure the holes are clear of debris. In rare cases, minor adjustments with a drill may be necessary, but contact support before modifying parts.
6.2 Operational Issues
- Doors Sticking or Not Closing Properly: Check hinges for any obstructions or damage. Ensure the shed is level, as an uneven base can affect door alignment. Lubricate hinges if necessary.
- Water Leakage: Verify all panels are securely fastened and sealed according to assembly instructions. Ensure the roof is properly installed and free of gaps. Check the foundation for proper drainage away from the shed.
