## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What is breakout force and why is it important for a wheel loader?
**A**: Breakout force measures the hydraulic power to dig into material piles. Higher kN ratings mean better loading efficiency for tough materials like gravel or rock.

### Q: How does bucket capacity affect wheel loader productivity?
**A**: Larger bucket capacity (measured in m³) allows more material per cycle, reducing total loading time. Match capacity to your typical material volume for optimal efficiency.

### Q: What maintenance does the hydraulic system require?
**A**: Regular hydraulic fluid changes, filter replacements, and hose inspections prevent leaks and maintain optimal pressure for boom and bucket operations.
