Operating Instructions
Doors:

Fixed Window:
A fixed window provides natural light inside the shed. It is not designed to open.

The shed includes integrated ventilation to help reduce condensation and maintain air circulation. Do not block these vents.
Maintenance
The Keter Premium 86 Resin Garden Shed is designed for minimal maintenance. Its polypropylene construction is UV-treated and waterproof, requiring no painting or special treatments.
- Cleaning: Clean the shed periodically with a mild soap and water solution. Avoid abrasive cleaners or harsh chemicals, as these can damage the resin.
- Inspection: Regularly check the shed for any signs of damage, loose screws, or debris accumulation, especially on the roof and around the base.
- Drainage: Ensure that the area around the shed allows for proper water drainage to prevent water pooling.
Troubleshooting
Door Misalignment:
If the doors do not close properly or appear misaligned, the most common cause is an uneven foundation. Verify that the shed is installed on a perfectly level surface. Adjust the base if necessary.
Water Leaks:
Although the shed is waterproof, leaks can occur if components are not assembled correctly or if seals are damaged. Check all connections and ensure screws are tightened appropriately. Inspect the roof and wall panels for any cracks or gaps.
Difficulty Assembling:
If you encounter difficulties during assembly, re-read the specific steps in the provided assembly guide. Ensure all parts are correctly oriented and that you are using the correct fasteners for each step. Do not force parts together; if they don't fit, recheck the instructions.
