4. Setup

4.1 Unpacking

Carefully remove all components from the packaging. Inspect for any damage. Ensure all parts listed in the manual are present.

4.2 Handle Assembly

Attach the upper handle to the lower handle using the provided knobs and bolts. Ensure the handle is securely fastened and aligned.

4.3 Grass Collection Bag Assembly

Assemble the grass collection bag according to the instructions. Typically, this involves attaching the fabric bag to the frame. Once assembled, lift the rear discharge flap and hook the grass bag onto the mower's rear discharge opening.

4.4 Battery Charging and Installation

Before first use, fully charge the 40V battery using the supplied charger. Connect the charger to a standard power outlet and insert the battery. The indicator light on the charger will show charging status. Once fully charged, insert the battery into the battery compartment on the mower until it clicks into place.

5. Operating Instructions

5.1 Adjusting Cutting Height

The MZK lawn mower offers 6 adjustable cutting height settings, ranging from 0.98 inches to 2.76 inches. To adjust the cutting height, locate the height adjustment lever on the side of the mower. Pull the lever outwards and move it to the desired position. Ensure all wheels are at the same height setting for an even cut.

5.3 Mowing Techniques

For best results, mow dry grass. Overlap each cutting pass slightly to ensure complete coverage. Avoid overloading the motor by cutting excessively long or wet grass. If the grass is very tall, consider raising the cutting height for the first pass and then lowering it for a second pass.

The MZK mower is designed for efficient cutting with a 16-inch cutting width and a 40L grass collection bag, maximizing mowing efficiency and reducing cleanup time.

6. Maintenance

6.1 Cleaning

After each use, disconnect the battery and clean the mower. Remove grass clippings from the cutting deck, wheels, and grass bag. Use a damp cloth to wipe down exterior surfaces. Do not use water jets or harsh chemicals.

6.2 Blade Care

Regularly inspect the blade for sharpness and damage. A dull blade can tear grass, leading to an unhealthy lawn. If the blade is dull or damaged, it should be sharpened or replaced by a qualified service technician. Always wear heavy-duty gloves when handling the blade.

6.3 Storage

Store the mower in a dry, well-ventilated area, away from direct sunlight and extreme temperatures. The MZK mower features a space-saving design, allowing it to be stored vertically, saving up to 70% of space in your garage or shed.
