5. Maintenance

Regular maintenance ensures optimal performance and extends the life of your lawn mower. Always disconnect the power cord before performing any maintenance.

5.1 Cleaning

• After each use, clean the underside of the mower deck to prevent grass buildup, which can affect cutting performance.
• Wipe down the exterior with a damp cloth. Do not use water jets or pressure washers directly on the motor or electrical components.
• Empty and clean the grass catcher regularly.

5.2 Blade Care

• Inspect the blade regularly for sharpness and damage. A dull blade tears grass, leading to an unhealthy lawn.
• If the blade is dull, it can be sharpened by a qualified service technician or replaced with a genuine Greenworks replacement blade.
• Ensure the blade is balanced after sharpening to prevent vibration.

5.3 Storage

• Clean the mower thoroughly before storing.
• Fold the handles for compact storage.
• Store the mower in a dry, secure location, out of reach of children.
