Maintenance
Regular maintenance ensures the longevity and optimal performance of your lawn mower.
- Disconnect Battery: Always remove the battery pack before performing any maintenance or cleaning.
- Clean the Mower:
- After each use, clean the underside of the mower deck to remove grass clippings and debris.
- Use a brush or damp cloth to clean the exterior. Do not use water jets or high-pressure washers directly on the motor or electrical components.
