Operating Instructions
1. Starting the Mower
Ensure the battery is fully charged and properly installed. To start the mower, press and hold the push-button start, then engage the bail switch (handle bar). Release the push-button once the mower starts. The mower will operate as long as the bail switch is held.
2. Adjusting Cutting Height
The mower features a single-point height adjustment lever, allowing you to select from seven different cutting heights, ranging from 1.5 inches to 4 inches. To adjust, pull the lever outwards and move it to the desired height setting. Ensure all wheels are at the same height setting for an even cut.

3. Mowing Tips
- For best results, avoid cutting wet grass.
- Do not attempt to cut more than one-third of the grass blade length at a time.
- Overlap cutting paths slightly to ensure complete coverage.
- Regularly check the grass collection bag and empty it when full to maintain optimal performance.

Maintenance
1. General Cleaning
After each use, disconnect the battery and clean the mower deck and blades. Use a damp cloth to wipe down the exterior. Remove any grass clippings or debris from the underside of the deck to ensure proper airflow and cutting performance. Do not use high-pressure water or immerse the mower in water.
2. Blade Care
Periodically inspect the mower 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 protective gloves when handling the blade.
3. Battery Storage
Store the battery in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, it is recommended to store the battery with a partial charge (around 50%) to prolong its lifespan. Do not store the battery in the mower.
