3. Mowing Techniques and Modes

The Greenworks 80V mower offers versatile cutting options:

• Avoid overloading the mower; if the motor slows down significantly, reduce your speed.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your mower. Always remove the battery before performing any maintenance.

1. Cleaning the Mower

• After each use, disconnect the battery.
• Tilt the mower on its side (with the battery compartment facing up) and use a stiff brush or plastic scraper to remove grass clippings and debris from the underside of the deck.
• Wipe down the exterior surfaces with a damp cloth. Do not use water hoses or pressure washers directly on the mower.

2. Blade Care

• Regularly inspect the blade for sharpness, bends, or cracks. A dull or damaged blade can lead to poor cutting performance and excessive battery drain.
• If the blade is dull, it can be sharpened by a qualified service center or replaced with a genuine Greenworks replacement blade.
• When replacing the blade, ensure the new blade is installed with the cutting edges facing the correct direction. Always wear heavy-duty gloves when handling the blade.

3. Battery and Charger Care

• Store batteries in a cool, dry place away from direct sunlight and moisture.
• If storing the battery for extended periods, charge it to approximately 50% capacity and recharge every 3-6 months to maintain battery health.
• Keep the charger clean and free of debris. Do not expose the charger to water.

4. Storage

• Remove the battery from the mower before storing.
• Clean the mower thoroughly.
• Fold the EZ Fold handles for compact storage. The mower can be stored vertically to save space.
