- Assembly Team: Due to its large size, assembly requires at least 2-3 people.
- Clearance: Ensure adequate clearance around the carport for safe entry, exit, and air circulation.
- Fire Safety: Keep all heat sources and open flames away from the canopy material.

5. Operation
The Benass carport is designed for ease of use and adaptability.
5.1 Roll-Up Zipper Door
The carport features a large roll-up zipper door for convenient vehicle access and enhanced air circulation. To open, unzip the door completely and roll it upwards, securing it with the attached ties. To close, unroll the door and zip it down fully to protect the interior.

5.2 Side Mesh Roll-Up Windows
Four side mesh roll-up windows are included to ensure optimal air circulation and prevent stuffiness inside the carport. To open, unfasten the window covers and roll them up, securing them with the ties. This allows airflow while keeping insects out. To close, unroll the covers and secure them to protect the interior from elements.

6. Maintenance
- Cleaning: Clean the canopy cover periodically with mild soap and water. Avoid harsh chemicals or abrasive brushes that could damage the material. Rinse thoroughly and allow to air dry completely before storage.
- Frame Inspection: Regularly check all frame connections and bolts to ensure they are tight and secure. Tighten any loose connections.
- Anchoring Check: Verify that all ground nails, wind ropes, and sandbags are securely in place, especially after strong winds or heavy rain. Re-tension ropes if necessary.
- Snow Removal: In areas with heavy snowfall, regularly remove accumulated snow from the canopy to prevent structural damage due to excessive weight.
- Storage: If disassembling for storage, ensure all components are clean and dry. Store the canopy in a cool, dry place away from direct sunlight to prolong its lifespan.
7. Troubleshooting
- Carport Instability: Ensure all frame connections are tight and all anchoring points (ground nails, wind ropes, sandbags) are properly secured. Re-check the levelness of the ground.
- Water Pooling on Canopy: Verify that the frame is assembled correctly and the canopy is taut. Ensure proper tensioning of the cover to allow water runoff.
- Zipper Malfunction: Check for any obstructions in the zipper teeth. Apply a silicone-based lubricant if the zipper is stiff. Avoid forcing the zipper.
- Damage from Wind: If the carport experiences strong winds, inspect the frame and canopy for any bends, tears, or loose connections. Replace damaged parts immediately.
