5. Maintenance
- Cleaning: Wipe the display and throttle unit with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials.
- Inspection: Periodically check all wiring connections for looseness or damage. Ensure the throttle lever moves freely without obstruction.
- Storage: When not in use for extended periods, store the scooter and its components in a dry, cool place away from direct sunlight.
6. Troubleshooting
- Display Not Turning On: Check battery connection and ensure the 6-pin connector is fully seated. Verify the scooter's main power is on.
- Throttle Not Responding: Ensure the throttle is properly connected to the controller. Check for any physical obstructions to the throttle lever. Verify the controller is receiving power.
- Inconsistent Performance: Inspect all wiring for damage or loose connections. Ensure the correct voltage controller (36V or 48V) is matched to your scooter's battery.
- Appearance Variation: Note that due to production batch differences, the appearance of the product may vary slightly, but its functionality remains the same.
