2. Safety Information
Please read and understand all safety instructions before assembly and use. Failure to follow these instructions may result in injury or damage to the product.
- Assembly Safety: Always assemble the cabinet on a clean, flat, and stable surface. Ensure all parts are present before beginning assembly.

- Children and Pets: Keep children and pets away from the assembly area. Do not allow children to climb on or play with the cabinet, as it may tip over and cause serious injury.

6. Maintenance
Proper maintenance will ensure the longevity and continued performance of your Wanfu Metal Storage Cabinet.
- Cleaning: The powder-coated finish is easy to clean. Use a soft, damp cloth with mild soap and water to wipe down surfaces. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish. Dry thoroughly after cleaning.
- Regular Inspection: Periodically check all screws and fasteners to ensure they remain tight. Re-tighten if necessary to maintain structural integrity.
- Door Hinges and Lock: If the door hinges become stiff, apply a small amount of silicone-based lubricant. Ensure the lock mechanism operates smoothly. Do not force the key if it feels stuck.
- Environmental Conditions: While durable, avoid exposing the cabinet to extreme humidity or direct prolonged moisture, which could lead to rust over time.
