Mowing Tips
- For best results, mow when the grass is dry.
- Do not attempt to cut more than one-third of the grass blade length at a time.
- Overlap cutting swaths slightly to ensure even coverage.
- Avoid sudden turns or stops while mowing.
- The 16-inch cutting width is ideal for small to medium-sized lawns.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your lawn mower.
Cleaning: After each use, disconnect the battery and clean the mower deck and grass collection bag. Use a damp cloth to wipe down surfaces. Do not use water jets or harsh chemicals.
Blade Care: Periodically inspect the cutting blade for sharpness and damage. A dull blade can tear grass, leading to an unhealthy lawn. If necessary, have the blade sharpened or replaced by a qualified service technician.
Battery Storage: Store batteries in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, charge batteries to approximately 50% capacity.
Storage: For convenient storage, the mower handle can be folded. Ensure the safety key is removed and batteries are disconnected before folding. Store the mower in a dry, secure location.
