Starting the Mower

3-in-1 Functionality
This mower offers versatile 3-in-1 functionality: mulching, bagging, and side discharge.
- Mulching: For finely cut grass clippings that return nutrients to your lawn. Ensure the side discharge chute is closed and the grass bag is removed.
- Bagging: For collecting grass clippings in the integrated 2 bushel/65L hybrid grass bag. Attach the grass bag securely and ensure the side discharge chute is closed. The bag features a full indicator for convenient monitoring.
- Side Discharge: For expelling clippings out the side of the mower. Attach the side discharge chute and remove the grass bag.

Maintenance
Regular maintenance ensures optimal performance and extends the life of your lawn mower.
- Clean the Deck: After each use, disconnect the battery and clean grass clippings from the underside of the mower deck to prevent buildup and ensure efficient cutting.
- Blade Inspection: Regularly inspect the cutting blade for sharpness and damage. A dull blade can tear grass, leading to an unhealthy lawn. Replace or sharpen as needed.
- Battery Care: Store battery packs in a cool, dry place. Do not store them in direct sunlight or where temperatures exceed 104°F (40°C).
- Storage: The foldable handle allows for easy vertical storage, saving space. Clean the mower thoroughly before storing for extended periods.
