3. Mowing Techniques

For best results, mow in straight, overlapping lines. Avoid cutting more than one-third of the grass blade length at a time. For thick or tall grass, consider raising the cutting height for the first pass and then lowering it for a second pass.

4. 2-in-1 Function (Mulching/Bagging)

To collect grass, ensure the grass collection bag is properly attached. To mulch, remove the grass collection bag and insert the mulching plug into the rear discharge opening. The mower will then finely cut and redistribute the grass clippings back onto the lawn.

Maintenance

1. Cleaning

After each use, remove the battery and safety key. Clean the underside of the mower deck and the grass collection bag to prevent grass buildup. Use a damp cloth to wipe down the exterior. Do not use high-pressure water or immerse the mower in water.

2. Blade Inspection and Sharpening

Regularly inspect the 40mm steel blade for sharpness and damage. A dull or damaged blade can affect cutting performance and battery life. If necessary, have the blade sharpened or replaced by a qualified service technician. Always wear protective gloves when handling the blade.

3. Battery Care

Store batteries in a cool, dry place away from direct sunlight and moisture. For long-term storage, ensure batteries are partially charged (around 50%) to prolong their lifespan. Greenworks lithium-ion batteries are designed without memory effect and are free of heavy metals.

4. Storage

For compact storage, the mower handles can be folded down. Ensure the mower is clean and dry before storing. Store in a secure, dry location out of reach of children.
