5.4 Grass Collection Bag

The 40L grass collection bag efficiently collects clippings, reducing cleanup time.

• Ensure the bag is properly attached before mowing.
• Monitor the bag's fill level. Empty the bag when it is full to maintain optimal cutting performance and prevent clogging.
• To empty, detach the bag from the mower and dispose of clippings. Reattach securely.

5.5 Mowing Tips

• For best results, especially with longer grass, start mowing at a higher cutting height (e.g., setting 3 or 4). After the initial pass, you can gradually lower the cutting height for a shorter trim. Attempting to cut very long grass at the lowest setting immediately may cause the motor to stall.
• Overlap cutting paths slightly to ensure an even cut.
• Mow in a pattern that directs clippings away from obstacles or previously mowed areas.

6. Maintenance

Regular maintenance ensures the longevity and performance of your MZK lawn mower.

• Cleaning: After each use, disconnect the battery and clean the mower deck, grass bag, and wheels. Remove any grass clippings or debris. Do not use water directly on electrical components.
• Blade Inspection: Periodically inspect the cutting blade for sharpness and damage. A dull or damaged blade can lead to poor cutting performance and strain the motor. Replace the blade if necessary.
• Storage: Store the mower in a dry, secure location. The lightweight design (approximately 26.5 lbs) and foldable handlebars allow for easy transport and space-saving vertical storage.

7. Troubleshooting

• Mower shuts off during operation:
  • Cause: Attempting to cut very long or thick grass at the lowest cutting height setting. The motor may not have sufficient power to handle excessive load.
  • Solution: Adjust the cutting height to a higher setting (e.g., 3 or 4) for the initial pass. Once the grass is shorter, you can gradually lower the cutting height for subsequent passes.
  • Cause: Battery charge is low or depleted.
  • Solution: Check the battery indicator lights. Recharge or replace with fully charged batteries.
  • Cause: Obstruction in the blade area.
  • Solution: Disconnect the battery, then carefully inspect and clear any debris from under the mower deck.
• Mower does not start:
  • Cause: Batteries not properly installed or depleted.
  • Solution: Ensure batteries are fully charged and securely seated in the compartment.
  • Cause: Safety button and trigger not activated correctly.
  • Solution: Press the safety button first, then pull the trigger lever.
