Safety Instructions
Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury when operating this appliance.
- Read All Instructions: Familiarize yourself with the controls and proper use of the mower.
- Wear Appropriate Attire: Always wear safety glasses or goggles, long pants, and sturdy footwear. Avoid loose clothing that could get caught in moving parts.
- Keep Area Clear: Ensure the mowing area is clear of debris, rocks, and other objects that could be thrown by the blade. Keep bystanders, children, and pets away from the operating area.
- Inspect Before Use: Before each use, check the mower for damaged parts, loose fasteners, or any other condition that may affect its safe operation.
- Handle Batteries Safely: Use only the specified batteries and charger. Do not charge batteries in damp or wet conditions.
- Avoid Wet Grass: Do not operate the mower in wet grass, as this can cause slipping and reduce cutting efficiency.
- Maintain Control: Always maintain a firm grip on the handle. Walk, do not run, behind the mower.
- Disconnect Power: Always remove the battery pack before cleaning, servicing, or when the mower is unattended.

Cutting Options (3-in-1 Functionality)
Your MZK lawn mower offers versatile cutting options:
- Bagging: For collecting grass clippings. Attach the 11-gallon collection bag to the rear discharge chute.
- Mulching: For finely cutting and returning clippings to the lawn as natural fertilizer. Ensure the mulching plug is inserted into the rear discharge opening and the collection bag is removed.
- Side Discharge: (Note: While the product is advertised as 3-in-1, the provided images and descriptions primarily show bagging and mulching. If a side discharge chute is included, attach it to the side of the mower.)

Maintenance
Regular maintenance ensures optimal performance and extends the life of your lawn mower.
- Clean After Each Use: Disconnect the battery pack. Use a brush or cloth to remove grass clippings and debris from the deck, blade area, and wheels. Do not use water directly on electrical components.
- Blade Inspection: Periodically inspect the blade for sharpness and damage. A dull or damaged blade can lead to poor cutting performance and strain the motor. Replace or sharpen the blade as needed.
- Battery Care: Store batteries in a cool, dry place away from direct sunlight. Do not store batteries in a discharged state for extended periods.
- Storage: For long-term storage, clean the mower thoroughly, remove the battery pack, and store it in a dry, protected area. The handle can be folded for compact storage.
