4.2 Installation Steps
- Mount the Motor: Securely attach the MY1020 motor to the go-kart frame using appropriate hardware. Ensure proper alignment for the chain drive.
- Install Drive Train: Mount the no-teeth freewheel and freewheel adapter onto the go-kart axle. Install the 55-tooth chain wheel. Connect the 25H chain, ensuring correct tension.
- Connect Motor to Controller: Connect the motor wires to the corresponding motor output terminals on the controller.
- Connect Battery: Connect your 36V battery pack to the battery input terminals on the controller. Ensure correct polarity (red to positive, black to negative).
- Install Key Switch: Mount the key switch with voltmeter in an accessible location. Connect its wires to the controller's power lock input.
- Install Pedal Throttle: Mount the pedal throttle in a comfortable position for the operator. Connect its wires to the controller's throttle input.
- Install Brake Sensor: Attach the brake sensor to the brake lever mechanism. Connect its wires to the controller's brake input.
- Optional Connections: If applicable, connect the brake light and general light wires to the controller.
- Final Check: Double-check all connections for security and correct wiring according to the diagram. Ensure no loose wires or potential short circuits.
5. Operating Instructions
- Power On: Insert the key into the key switch and turn it to the 'ON' position. The voltmeter display will show the current battery voltage.
- Start Operation: Gently press the foot pedal throttle to engage the motor and begin movement. The speed will increase as the pedal is pressed further.
- Braking: Apply the go-kart's brake. The brake sensor will signal the controller to cut power to the motor, allowing the brakes to function effectively.
- Power Off: To stop operation, release the throttle and turn the key switch to the 'OFF' position. Remove the key for security.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your motor kit.
- Chain Lubrication: Periodically lubricate the drive chain to reduce wear and ensure smooth operation.
