Operating Instructions
Starting the Mower
To start the mower, pull the safety bail lever towards the handle and then press the power button. The mower will start instantly. Release the power button but keep the safety bail lever engaged to continue operation.
Self-Propelled Control
Engage the self-propelled function by holding down either the left or right self-propel lever. Adjust the drive speed using the slider on the control panel, from 'turtle' (slow) to 'rabbit' (fast), to match your walking pace and terrain.

The control panel provides battery status, turbo mode activation, and adjustable drive speed for the self-propelled function.
Turbo Mode
For thicker grass or heavy leaf pickup, press the 'TURBO' button on the control panel. This increases the blade speed for maximum cutting power. Release the button to return to standard operation.
LED Headlights
The integrated LED headlights provide illumination for mowing in low-light conditions, such as early mornings or late evenings.

Maintenance
Cleaning
After each use, ensure the mower is clean. Remove any grass clippings, dirt, or debris from the cutting deck, wheels, and battery compartment. Use a damp cloth for cleaning; do not use high-pressure water or immerse the mower in water.
Blade Care
Regularly inspect the cutting blade for sharpness and damage. A dull blade can tear grass, leading to an unhealthy lawn. Replace or sharpen the blade as needed. Always wear heavy-duty gloves when handling the blade.
Battery Care and Storage
Store batteries in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, ensure batteries are partially charged (around 50%).
Storage
The mower features EZ Fold handles that collapse vertically, allowing for compact storage. This design saves up to 70% space, making it ideal for garages or sheds.

The EZ Fold handles allow for quick vertical storage, saving significant space in your garage or shed.
