Mowing Techniques
- For best results, mow when the grass is dry.
- Overlap cutting swaths slightly to ensure an even cut.
- Avoid cutting more than one-third of the grass blade length at a time.
- The 8-gallon grass collection bag efficiently collects clippings, reducing post-mowing cleanup. Empty the bag when it is full to maintain optimal performance.

Maintenance
Regular maintenance ensures optimal performance and extends the life of your mower.
- Cleaning: After each use, disconnect the battery and clean the mower deck and blade with a brush or cloth. Do not use water directly on electrical components.
- Blade Care: Inspect the blade regularly for sharpness and damage. A dull or damaged blade can lead to poor cutting performance and strain the motor. Replace the blade if it is bent or severely damaged.
- Battery Storage: Store the battery in a cool, dry place. For long-term storage, charge the battery to approximately 50% and recharge every 3-6 months.
- General Storage: Store the mower in a dry, protected area. The lightweight and compact design allows for easy storage in small spaces.
