2. Electrical Wiring
- Ensure the power source (e.g., 24V battery) is completely disconnected.
- Connect the motor's red wire to the positive (+) terminal of your 24V DC power supply.
- Connect the motor's black wire to the negative (-) terminal of your 24V DC power supply.
- Verify all connections are tight and properly insulated to prevent any short circuits or accidental disconnections.
- It is recommended to use an appropriate motor controller (not included) for speed regulation and protection. Connect the motor to the controller according to the controller's instructions.

3. Chain Installation
- Install the 25H chain onto the motor's 10T sprocket and the driven sprocket on your vehicle.
- Adjust chain tension to ensure it is neither too tight nor too loose. Proper tension prevents excessive wear and ensures efficient power transfer.
Operating Instructions
Once the motor is correctly installed and wired, you can begin operation:
- Initial Test: Before full operation, perform a brief test to ensure the motor spins freely and in the correct direction.
- Speed Control: If using a motor controller, adjust the speed gradually to avoid sudden jolts or excessive strain on the motor.
- Load Management: Avoid overloading the motor beyond its rated capacity (250W) to prevent overheating and premature wear.
- Monitoring: During initial use, monitor the motor for any unusual noises, vibrations, or excessive heat.
Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your motor:
- Cleaning: Periodically clean the exterior of the motor to remove dust, dirt, and debris. Use a dry cloth; avoid using water or harsh chemicals.
- Inspection: Regularly inspect the motor for any signs of damage, loose connections, or wear on the sprocket.
- Brush Replacement: As a brushed motor, the carbon brushes will wear over time. Consult a qualified technician for brush inspection and replacement if performance degrades significantly.
- Storage: When not in use for extended periods, store the motor in a dry, clean environment away from direct sunlight and extreme temperatures.
