This crawler crane model is mainly for display and collection. To use it, simply take it out of the box and place it on a stable surface. When handling, make sure to hold it gently to avoid any damage. Store it in a dry and dust - free place to keep it in good condition. If it gets dirty, you can use a soft, dry cloth to wipe it clean. Do not expose it to extreme temperatures or humidity. Since it's a detailed model, be careful not to touch the small parts too roughly to prevent them from breaking off.
