2. Important Safety Instructions
Always observe the following safety precautions to reduce the risk of injury or damage:
- Read the Manual: Familiarize yourself with all instructions and warnings before operating the spreader.
- Personal Protective Equipment (PPE): Always wear appropriate safety glasses, gloves, and a dust mask when handling granular materials and operating the spreader.
- Keep Area Clear: Ensure children, pets, and bystanders are kept at a safe distance from the operating area.
- Not Waterproof: This device is NOT WATERPROOF. Do not expose the spreader to rain, moisture, or immerse it in water. Water contact with the battery and motor can cause damage or electric shock.
- Proper Storage: Store the spreader in a cool, dry, and well-ventilated place, away from moisture and direct sunlight.
- Battery Care: Charge the battery periodically (every 3-6 months) to prevent damage and extend its lifespan, even when not in use.
- Material Compatibility: Use only dry, granular materials. Do not use liquids or sticky substances.
- Avoid Obstructions: Be aware of potential obstructions that could cause clogging or damage to the dispersion wheel.
- Power Off: Always turn off the power before cleaning, adjusting, or performing any maintenance.

4. Setup and Charging
4.1 Initial Setup
Upon unboxing, inspect the spreader for any signs of damage. Ensure all components listed in Section 3 are present.
4.2 Charging the Battery
The spreader is powered by a built-in 7.2V DC, 2.0Ah Lithium-ion battery. For optimal performance and battery longevity, fully charge the spreader before its first use.
- Locate the USB Type-C charging port (Socket for Charge Plug) on the spreader.
- Connect the provided USB Type-C cable to the spreader's charging port.
- Connect the other end of the USB cable to a USB power adapter (a 30W or higher adapter is recommended, not included).
- The Charger LED Indicator will illuminate to show charging status.
- A full charge typically takes 2-4 hours, depending on the power supply output current. The LED indicator will change or turn off when charging is complete.
Note: To extend battery life, recharge the device at least once every 3-6 months, even if not in regular use.

5. Operation
5.1 Filling the Hopper
Ensure the spreader is turned off before filling. The hopper has a 2.5L capacity.
- Hold the spreader upright and steady.
- Carefully pour your desired granular material (fertilizer, seeds, salt, etc.) into the hopper. Do not overfill.
- Ensure the material is dry and free of clumps to prevent clogging.

5.2 Adjusting Material Flowrate (8-Level Settings)
The Material Flowrate Adjustment Knob allows you to control the amount of material dispensed. There are 8 settings:
- Levels 1-3: Ideal for fine grass seeds and very light applications.
- Levels 4-6: Suitable for moderate fertilizers and general spreading.
- Levels 7-8: Best for heavy rock salts, de-icers, or coarse materials.
Rotate the knob to select the desired level based on the material type and desired coverage.

5.3 Adjusting Seeding Angle (Throw Width)
The Throw Width Adjustment Lever allows you to modify the spread pattern and distance. There are 6 seeding angles, with a maximum adjustable angle of 127°.
- Move the lever to adjust the angle. A wider angle will cover a larger area.
- Experiment with different settings to achieve the desired coverage for your specific application.

5.4 Adjusting Motor Speed (6 Speeds)
The Speed Adjustment Knob controls the rotation speed of the dispersion wheel, ranging from 900 to 2200 rpm/min. Higher speeds generally result in a wider and more forceful spread.
- Rotate the knob to select one of the 6 available speeds.
- Use lower speeds for more controlled, localized spreading and higher speeds for broader coverage.

5.5 Spreading Operation
- Once the hopper is filled and settings are adjusted, hold the spreader firmly by the handle.
- Position yourself over the area you wish to spread.
- Press and hold the Trigger to activate the dispersion wheel.
- Walk at a steady pace, moving the spreader evenly over the area to ensure consistent coverage.
- Release the Trigger to stop the dispersion.
The spreader can cover up to 3,767.36 sq. ft. for fertilizers and 6,458.34 sq. ft. for grass seed on a single fill, depending on material and settings.
6. Maintenance and Storage
6.1 Cleaning
Regular cleaning ensures optimal performance and extends the life of your spreader.
- After each use, turn off the power.
- Empty any remaining material from the hopper.
- Use a dry cloth or a soft brush to remove any residue from the hopper, dispersion wheel, and exterior.
- IMPORTANT: Do not use water or cleaning solutions directly on the spreader, especially near the battery and motor compartments, as the device is not waterproof.
6.2 Storage
When not in use, store the spreader in a cool, dry, and well-ventilated place, away from direct sunlight and moisture. Consider using a dust cover to protect the device.
Remember to charge the battery periodically (every 3-6 months) even during storage to maintain its health.
7. Troubleshooting
Here are solutions to common issues you might encounter:
| Problem | Possible Cause | Solution |
|---|---|---|
| Spreader not turning on / No power. | Battery is depleted. | Charge the battery fully using the provided USB cable and a suitable power adapter. |
| Material not dispensing or dispensing slowly. | Clogging under the dispersion wheel. Material is wet or clumpy. Flowrate setting is too low. |
|
| Uneven spreading pattern. | Incorrect seeding angle or speed setting. Inconsistent walking speed. |
|
| Battery life is shorter than expected. | Battery not fully charged. Battery degradation due to infrequent charging. |
