5.2 Mowing Modes

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your lawn mower.
- Cleaning: After each use, clean the mower housing and cutting deck. Remove grass clippings and dirt using a brush or cloth. Do not use high-pressure cleaners or running water directly on electrical components.
