Maintenance
Regular maintenance ensures your mower remains in top condition.
- Battery Care: Store the battery in a cool, dry place. The advanced Lithium-Ion battery is designed to hold its charge for 12+ months when not in use. Avoid fully discharging the battery before recharging to prolong its lifespan.

- Deck Cleaning: After each use, clean the underside of the mower deck to prevent grass clippings from building up, which can affect cutting performance and airflow.
- Storage: The EZ Fold™ aluminum handles allow for compact vertical storage, saving up to 70% in storage space. Ensure the mower is clean and dry before storing.
