2.3 Deck Height Adjustment
Adjust the cutting height using the single-lever height adjustment mechanism. There are 6 positions available to suit various grass lengths and preferences.
3. Operation
3.1 Starting the Mower
To start, ensure batteries are installed and the safety key is engaged. Press the push-button start. The brushless motor will provide instant power.
3.2 Self-Propelled Drive
Engage the self-propelled drive using the control lever on the handle. Adjust the speed with the touch of a lever. This feature reduces effort, especially on hills and slopes, ensuring a consistent cut.
3.3 3-in-1 Deck Functions
The 22” steel deck allows for three cutting modes:
- Rear-Bagging: For collecting grass clippings. The Vortex tunnel design ensures high capacity.
- Mulching: For finely cutting and returning clippings to the lawn as natural fertilizer.
- Side-Discharge: For expelling clippings out the side of the mower.
3.4 Torque-Sense Control
The mower is equipped with Torque-Sense Technology. Sensors in the motor detect when more power is needed for thick, dense, or wet grass, automatically increasing blade speed for a premium cut. This optimizes power usage and extends runtime.
4. Maintenance
4.1 Battery Care
- Always use the provided 4 Amp fast charger.
- Store batteries in a cool, dry place away from direct sunlight.
- Avoid fully discharging batteries before recharging to prolong their lifespan.
4.2 Cleaning
- After each use, clean the underside of the deck to prevent grass buildup, which can affect cutting performance.
- Wipe down the exterior of the mower with a damp cloth. Do not use a pressure washer.
4.3 Blade Maintenance
Regularly inspect the mower blade for sharpness and damage. A dull blade can tear grass, leading to an unhealthy lawn. Sharpen or replace the blade as needed. Always disconnect batteries before performing any blade maintenance.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Mower does not start | Batteries not charged or improperly installed; Safety key not engaged; Overload protection activated. | Ensure batteries are fully charged and correctly inserted. Check if the safety key is fully engaged. Allow the motor to cool down if it was recently overloaded. |
| Poor cutting performance | Dull or damaged blade; Grass buildup under deck; Cutting too much grass at once. | Sharpen or replace the blade. Clean the underside of the deck. Raise the cutting height or mow more frequently. |
| Self-propelled feature not working | Drive lever not fully engaged; Obstruction in drive wheels. | Ensure the drive lever is fully engaged. Check for and remove any debris around the drive wheels. |
| Reduced battery runtime | Batteries not fully charged; Old or worn batteries; Mowing thick/wet grass. | Ensure batteries are fully charged. Consider replacing old batteries. Mow when grass is dry and avoid excessively thick areas if possible. |
