Setup and Customization
The Evergreen 300 case comes with pre-scored pick and pluck foam, allowing you to create custom compartments for your specific items. This ensures a snug and secure fit, preventing movement and potential damage during transport.
- Prepare Your Items: Arrange the items you wish to store inside the case on top of the foam insert to visualize the optimal layout.
- Mark the Outline: Gently press the items into the foam to leave an impression, or use a marker to outline their shapes.
- Pluck the Foam: Carefully remove the pre-scored foam cubes corresponding to your marked outlines. Start with smaller sections and expand as needed to achieve a precise fit.
- Test Fit: Place your items into the newly created compartments to ensure they fit securely without excessive pressure or looseness. Adjust by plucking more foam if necessary.
- Lid Foam: The lid also contains convoluted foam (egg-crate foam) which provides additional cushioning and holds items firmly in place when the case is closed.

Operating the Case
Using your Evergreen 300 case is straightforward, designed for maximum security and ease of access.
- Opening: To open the case, lift the two Twist Lock Latches located on the front. These latches are designed for secure closure and easy release.
- Closing: To close, align the lid with the base and press down firmly until both Twist Lock Latches click into place. Ensure a complete seal for waterproof and dustproof integrity.
- Pressure Equalization: The Twist Lock Latches also function as automatic pressure equalization valves. This system automatically adjusts internal pressure to match external atmospheric pressure, preventing vacuum lock and making the case easy to open after changes in altitude or temperature.

Maintenance and Care
To ensure the longevity and continued performance of your Evergreen 300 protective case, follow these maintenance guidelines:
- Cleaning: Wipe the exterior of the case with a damp cloth and mild soap. Avoid harsh chemicals or abrasive cleaners that could damage the material.
- Gasket Inspection: Periodically inspect the O-ring gasket around the lid for any signs of wear, cracks, or debris. A clean, intact gasket is crucial for maintaining the waterproof seal.
- Gasket Lubrication: If the gasket appears dry, apply a thin layer of silicone grease (not petroleum-based products) to keep it pliable and ensure a proper seal.
- Foam Care: The pick and pluck foam can be gently vacuumed to remove dust or small debris. If it becomes heavily soiled, it may be replaced.
- Storage: Store the case in a cool, dry place away from direct sunlight when not in use. For long-term storage, it is recommended to leave the latches unfastened to prevent compression of the gasket.
Troubleshooting
If you encounter any issues with your Evergreen 300 case, refer to the following common troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Case is difficult to open. | Pressure differential (e.g., after air travel or temperature change). | The automatic pressure equalization system should handle this. If not, ensure latches are fully disengaged. |
| Water inside the case. | Damaged or dirty O-ring gasket; latches not fully secured. | Inspect and clean the O-ring gasket. Ensure latches are fully closed and sealed. Replace gasket if damaged. |
| Items not fitting securely. | Incorrect foam plucking; foam wear. | Re-evaluate foam cutouts. Consider replacing the foam insert if it has lost its density or shape. |
