  • Grass Collection: Monitor the grass bag fill indicator. Empty the grass bag when it is full to maintain optimal collection performance.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your lawnmower. Always remove the safety key and batteries before performing any maintenance.
