4.5. Grass Collection Bag / Mulching

Your mower offers 2-in-1 functionality: rear bagging or mulching. To use the grass collection bag, ensure the mulching plug is removed, then attach the bag to the rear discharge opening. For mulching, remove the grass bag and ensure the mulching plug is securely inserted into the discharge opening.

5.2. Mowing Techniques

For best results, mow dry grass. Overlap cutting swaths slightly to ensure an even cut. For thick or tall grass, consider raising the cutting height and making two passes. The 5.0Ah battery provides sufficient runtime for yards up to approximately 1/4 acre on a single charge.

6. Maintenance

6.1. Cleaning

After each use, remove the battery and clean the mower deck, blade, and grass bag. Use a brush or cloth to remove grass clippings and debris. Do not use water directly on electrical components.

Regularly inspect the blade for sharpness and damage. A dull or damaged blade can lead to poor cutting performance and may require sharpening or replacement. Always wear heavy-duty gloves when handling the blade.

6.3. Battery Storage

Store the battery in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, ensure the battery is partially charged (around 50%) to prolong its lifespan.

6.4. Mower Storage

The mower features an easy folding design for convenient, space-saving upright storage. Clean the mower thoroughly before storing. Fold the handle down and store the mower in a dry, protected area.
