Important: Double-check all connections before applying power. Incorrect wiring can damage the components.
5. Operating Instructions
Once installed, operate your electric vehicle as follows:
- Power On: Turn on the power lock switch (if installed) or the main power switch for your battery.
- Throttle Control: Gently twist the throttle to accelerate. The speed will increase proportionally to the throttle input.
- Braking: Engage the brake lever to slow down or stop. The controller may cut power to the motor when the brake is applied.
- Charging: When the battery is low, connect your compatible charger to the charging port.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your motor kit.
- Cleaning: Keep the motor and controller free from dirt, dust, and moisture. Use a dry cloth for cleaning.
- Connections: Periodically inspect all electrical connections for tightness and signs of corrosion.
- Fuse Replacement: If the system loses power unexpectedly, check the fuse in the fuse cable. Replace a blown fuse only with a fuse of the same rating (20A or 25A, depending on your system's requirements).
- Motor Inspection: Check the motor's sprocket and chain for wear and proper tension.
