Preparation:

Assembly Tips:
- Wall Panel Installation: Press wall panels firmly downward during installation to ensure they fully snap into the floor channel. This is crucial for stability and weather resistance.
- Window Placement: The windows are adjustable. You can install them according to the placement of the product and your specific needs for light and ventilation.
- Secure Fasteners: While assembly requires fewer screws, ensure all fasteners are tightened securely without over-tightening, which could strip plastic threads.

Operating Instructions
Your Greesum storage shed is designed for convenient and secure storage.
Door Operation:
- The shed features a double-hinged door system. To open, unlatch the door handles and pull outwards.
- To close, push the doors firmly until they meet, then engage the latches.
- Lockable Design: The door includes a lockable mechanism for added security. Use a padlock (not included) through the designated holes on the door handles to secure your belongings.

Maintenance
Regular maintenance will ensure the longevity and optimal performance of your Greesum storage shed.
- Cleaning: Clean the shed exterior periodically with mild soap and water. Avoid abrasive cleaners or harsh chemicals, which can damage the plastic material. Rinse thoroughly with clean water.
- Inspection: Annually inspect all panels, roof sections, doors, and windows for any signs of damage or loose fasteners. Tighten any loose screws.
- Drainage: Ensure that the area around the shed has proper drainage to prevent water accumulation, which could affect the shed's base.
- Snow Removal: In areas with heavy snowfall, gently remove excessive snow from the roof to prevent structural stress.
Troubleshooting
Here are solutions to common issues you might encounter:
- Doors do not close properly:
- Ensure the shed is assembled on a perfectly level surface. Uneven ground can cause door misalignment.
- Check for any obstructions in the door frame or hinges.
- Verify that all wall panels are fully seated into the floor channels.
- Water leakage:
- Inspect all roof and wall panel connections to ensure they are securely fastened and sealed.
- Check window seals for any gaps or damage.
- Ensure proper drainage around the shed to prevent water from pooling at the base.
- Missing parts:
- Confirm all 6 packages have been received.
- Carefully re-check all packaging materials for small components.
- If parts are still missing, contact Greesum customer support (see Support section).
