Maintenance

General Care

• Cleaning: After each use, disconnect the battery and clean the mower deck and wheels to prevent grass buildup. A damp cloth is usually sufficient.
• Inspection: Regularly inspect the mower for any loose parts, damage, or wear.

Blade Care

The 21-inch cutting blade should be kept sharp for optimal performance. Periodically inspect the blade for sharpness and damage. If the blade is dull or damaged, it should be sharpened or replaced by a qualified service technician.

Storage

For compact storage, the ergonomic handle features quick-release knobs that allow it to be easily folded. Store the mower in a dry, protected area, away from direct sunlight and extreme temperatures. Remove batteries before long-term storage.
