4. Operating Instructions
Follow these steps for safe and effective operation of your lawn mower.
4.1 Pre-Operation Checklist

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your lawn mower.
5.1 Regular Cleaning

- Inspect the blade regularly for damage, dullness, or imbalance.
- A dull blade tears grass, leading to an unhealthy lawn. Sharpen or replace the blade as needed.
