描述

## Usage Instructions
1. Avoid violent impact, sharp‑object scratching and over‑load bearing to prevent wheel cracking and shaft deformation.
2. Keep away from corrosive liquids, dust‑filled and damp environments for long‑time exposure to slow down bearing aging.
3. The manufacturer shall not be liable for damage caused by overweight use or man‑made destruction.

## Precautions
1. Regularly clear debris around wheels and add lubricant for flexible rotation.
2. Check for cracks, wobble and loose axles before use, replace damaged wheels promptly.
3. Prevent long‑term friction against rugged sharp ground.
4. Keep spare small‑size wheels away from young kids to avoid choking risks.
